Pd 10 1 volume of concrete m3. Plate road PD10. The use of well plates

One of the most important components in the design of various types of motorized equipment is the engine start system. The reliability of work, the speed of turning on the motor, and therefore its correct operation, directly depend on it. Launcher PD 10 is mounted on a tractor MTZ equipment, which is considered to be the most common.

The starting engine PD 10 is designed to ensure a stable start of the motor of MTZ tractors, it stands out among other analogues with its excellent technical characteristics, high stability of operation. It is a standard starter equipped with one cylinder. Its working volume is 0.346 liters, which is quite enough to start the engine even in adverse conditions. The power of the unit at 3.5 thousand revolutions reaches 10 hp.

Having studied specifications products, it should be noted that it belongs to the two-stroke type, equipped with a crank-chamber purge. The engine runs on a gasoline mixture, the quality of which is regulated by a carburetor, which allows finer tuning of the engine. The principle of operation of such a device is extremely simple.

First, the PD-10 is started through the standard tractor starter, after which it is connected to the main engine vehicle. With the help of mechanisms, the energy of rotation is transmitted to the gearbox and, subsequently, the tractor crankshaft gains the necessary speed for stable independent operation. After the main engine has reached the working state, the starting analogue stops its work.

Scheme of the device of the starting engine PD-10

The starting motor of this brand consists of a number of components and seems to be a complex technical unit designed to ensure a stable start of the MTZ tractor engine. Studying its device, we can distinguish the following key elements designs:

• cylinder. Mounted on the crankcase with nuts. Purge channels, well located tangent to the circumference of the node, reduce the leakage of the mixture with the exhaust. The cylinder head is equipped with a glow plug;
• piston. Manufactured from high strength aluminum alloy. His hallmark is a spherical bottom, which improves the quality of cleaning the cylinder from exhaust gas. In order to achieve the correct position of the piston, it should be placed in such a way that the arrow on its bottom points towards the rear axle of the crankshaft;
• crank mechanism. Made of special grade steel, equipped with a bronze bushing. The heads of the mechanism are one-piece, and the bearing is double-row, roller type;
• gears;
• crankshaft. Roller bearings with rubber seals act as its support. In order to equalize the centrifugal force, the knees of the cheeks are equipped with special weights;
• the cooling system of the unit is connected to a similar system of the main motor.

These elements are key and take the most Active participation in the operation of this engine. At the same time, there are many other constituent parts, like pins, rings, windows and other accessories.

Service PD-10

As a rule, the launcher will not require a lot of time from the owner to perform node maintenance work. It is important to remember that the use of fuel in its pure form, without pre-mixing with oil, is strictly prohibited, as this can lead to engine damage and subsequent failure.

In order to fill the engine, you will need to mix clean gasoline of good quality and engine oil in a clean container, strictly observing the proportions of 15: 1. It is necessary to use a special funnel-filter when filling, which will avoid the ingress of large and small contaminants into the internal components of the unit.

Scheme PD-10

As you use, you should flush the sump of the fuel tank, and also wash or replace the air filter in a timely manner. It is recommended to do this every 480 hours of use. Since many of the problems that arise with the launcher are related to the unsatisfactory cleanliness of the air filter, it should be periodically dismantled and cleaned, following the instructions below:

1. Remove the protective cap of the air purifier and the restrictive mechanism.
2. Remove filter.
3. Rinse it in diesel fuel, then moisten it with oil.
4. Install filter, restrictor and cap.

It is necessary to pay due attention to the maintenance of the gearbox operating in conjunction with the PD-10. First of all, you should change the oil after 960 hours of operation, and top it up every 480 hours, as needed.

With a similar frequency, the performance of the clutch assembly should be checked. During operation, it is necessary to remember that the launcher operation time should not exceed 10 minutes, otherwise the probability of its failure increases significantly.

Setting and adjustment

From correct setting engine, including PD 10u, depend on its technical indicators, as well as stability and performance. Adjustment of the device is carried out in several stages, the first of which is considered to be the setting of the carburetor.

To do this, you should set the length of the rod between the damper and the regulator, after which, adjust the engine at low speeds. After that, they begin to adjust the crankshaft, which can be done using the appropriate spring. The more it is compressed, the higher the engine speed is.

Then, it is necessary to start setting up the ignition system, and the last, final step will be setting up the mechanism responsible for turning off the drive gear.

Conclusion

PD-10 can be called one of the most important units installed on tractors manufactured by MTZ. They have the necessary characteristics for a stable engine start, unpretentious in maintenance and care. Thanks to this combination, the 10 series launchers have become incredibly widespread.

Base plates are used in construction for the arrangement of prefabricated wells for various purposes, installed on the carriageway of city and regional highways. Unloading, support plates play an important role in the design of the well, evenly distributing the physical load on the well. In the center of the plate there is a technological hole for installing a cast-iron hatch.

Deciphering the marking

The marking of the base, unloading plates contains an alphabetic and numeric designation, which determine the name of the product and its size. There are several types of base plates used in construction:

• UOP-6 - unified base plate;
• OP - base plate;
• 1K - standard size of the product, for a round cast-iron hatch;
• 1D - standard size of the product, under the storm water inlet;
• PD - base plate, road;
• 6 - standard size of the product;
• PYAP - anchor plate, rectangular;
• OUP - basic universal rectangular

Reinforced concrete base slabs are made of heavy high-strength concrete, according to the sketches of GI "Mosinzhproekt" in accordance with GOST 8020-90 "Reinforced concrete products for manholes of water and sewer networks", working drawings "Mosinzhproekt" Album PS-34-1.

Production and quality control

Reinforced concrete unloading slabs are manufactured in batches and checked by the Quality Control Department for compliance with the requirements of GOST 13015-2012. The indicators of tempering strength, water resistance and frost resistance of concrete are most carefully checked. The geometric parameters of the product are also measured, in order to determine the deviation of the geometric parameters of the finished product.

Production is carried out in the factory in specialized forms, from concrete of class B20, grade M-250 by vibroforming according to GOST 8020-90. The price of base plates consists of the volume of concrete required for production and specialized plasticizer additives. Compliance with all standards gives a guarantee of the quality of the finished product and an increase in service life.

Concrete bottoms of round wells PD 15-1

Underground sections of the city pierce vital systems: gas pipeline, sewerage, water and heat supply, drainage, etc. Therefore, back in the Soviet period, materials were designed to quickly create wells - trunks for quick penetration into the network. In addition to public utilities, wells were dug in private households, at agricultural and industrial enterprises.

Due to factory readiness and low price, having bought wall rings, bottom plates, well covers, developers could get a strong well of the required size in a matter of days. The diameters of wells for urban needs are from 1 to 2 meters. Depth from 2 to 7 meters. The trunk is formed from concrete rings of the KS. And the bottom of the plate KCD, PD. Sometimes, the developer tries to save money and buy rings with the bottom of the KSD, in the shape of a glass. Design drawings of universal products for water management construction include the project Series 3.820-9 issue 1.

Well bottom plates - characteristics, dimensions, price

Round slab - the base of a cylindrical reinforced concrete well, a high-strength flat slab of the appropriate shape. Structures of this type are buried no more than 7 meters. Bottom slabs according to series 3.820-9 have a thickness of 100,120, 140 mm - optimal for distributing typical well loads. Loads from soil pressure, concrete rings, pipelines, own weight affect the bottom plate PD 15-1, therefore, inside the product there are grids made of steel coated with an anti-corrosion compound.

The diameters of the bottom plates depend on the inner diameter of the rings KS, KTs - according to the project Series 3.820-9, these are 1000, 1500 and 2000 mm. Also on sale you can find products from 750 to 2500 mm in other series. You can find all sizes of plates, trays, well rings, well covers in the catalog "Reinforced Concrete Products Directory". The panels are expected to have strength, rigidity and crack resistance, the ability not to grow or rot.

A high-strength reinforced concrete element serves as the basis for underground water supply and sewage wells, often bottom slabs are used as a support for private systems, various cellars, cesspools, agricultural buildings, drinking wells. The use of the PD 15-1 slab is not necessary only with working chambers or well rings; concrete well bottoms are often bought for the construction of brick and stone walls of wells. The bottom diameter corresponds to the well diameter from 1000 to 2000 mm. The minimum diameter is set at least 80 cm so that, if necessary, a person can get inside. Operation of well bottoms is admissible in any climatic conditions, in dry and water-saturated soils.

The use of plate products

Modern type album series 3.820-9 issue 1 includes only elements of round wells, which are arranged everywhere for a variety of purposes. The main task of concrete slab designers was versatility - the standard album PD 15-1 includes only five standard sizes of slabs that satisfy all the needs of construction. In 2017, the production of well products determines the new GOST 8020-2016, you can download it for free in the section of the site "GOSTs and SNiPs".

Plates of the PD type are also called KCD - well cylindrical bottoms. They are laid on the very bottom of the well and become the basis for the subsequent building of the well shaft. Series 3.820-9 does not imply the presence of well chambers, therefore the wall rings of wells are mounted directly on the bottom. The task of plate products such as PD 15-1 is the stability and insurance of well rings from shifting and subsidence.

Dimensions, loads and requirements for the production of well bottoms are fixed in GOST 8020-90 Concrete and reinforced concrete structures for wells. Similar products include issue 7 series 3.900.3 and in the project series 3.900.1-14. Universal well bottom plates can be used in various septic tanks, pits, brick wells, etc.

Bottom plates: materials and characteristics

Since the work of well reinforced concrete daily involves contact with soil, groundwater, liquid media of various aggressiveness, concrete for the production of bottoms is selected with reduced permeability. Water absorption of such boards PD 15-1 is not more than 8% by weight. The water resistance class for ordinary products is set to W4, if you need to buy bottom plates for work in aggressive environments, it is recommended to order plates of a higher class. Frost resistance of concrete of well bottoms is set according to the proposed region of construction (at least F100). Production in Khabarovsk, Omsk, Krasnoyarsk, Ulan-Ude, Irkutsk, Sochi, Stavropol adapts to climatic needs, simulating the necessary indicators of protection against temperature fluctuations.

To prevent erosion, wear and corrosion, the manufacturer carefully protects the PD 15-1 boards. The manufacture of well bottoms from concrete of heavy grades M200 (B15) ensures compliance with GOST in terms of strength, rigidity and crack resistance. The quality of the bottom ring plates is controlled at each stage of production, then tested in the laboratory. Reinforcement of the bottom plates is carried out with welded meshes of steel A-I, A-II, A-III, Bp-I and A-IIIc as necessary.

The protective layer of concrete up to the reinforcement is at least 1.5 cm. Internal steel parts and embedded products go through the production stage of anti-corrosion protection. To increase the service life of well bottoms, it is necessary to hydrophobize and isolate the seams and the products themselves. The price list for elements of wells according to the project Series 3.820-9 includes current prices for well bottoms. Price fluctuations directly depend on the cost of energy, steel and concrete.

Factory reinforced concrete for the construction of water supply and sewerage networks was revised in 2016, since then reinforced concrete products have been actively produced according to the 3.820-9 series. Today, technologists of factories of reinforced concrete products pay attention to the quality and characteristics of concrete mix formulations. Therefore, before ordering bottom plates and well rings, it is necessary to indicate the required class of water tightness and frost resistance of concrete. The mass of the bottom plate PD 15-1–925 kg, this allows it to be well fixed in the ground and avoid shifting even during vibrations. Installation of well bottoms is carried out on a sandy base and a layer of mortar 100 with a thickness of at least 10 mm. In the Complex-S company, you can buy well bottom plates of any size and in the required configuration. Delivery of reinforced concrete is carried out quickly and carefully throughout Russia. Lifting and installation of the bottom plate is carried out using steel hinges included in the design.

Bottom plate marking

Series 3.820-9 and GOST 8020-2016 regulate the marking of well bottoms as follows. The alphanumeric combination of the brand includes the name of the product and the diameter of the well. As an example, consider the bottom of the well PN 10 (1500x1500x100 mm), which can also be called KCD. PN - bottom plate, 10 - well diameter 1000 mm. The brand, weight, date of issue and the OTK stamp are applied to the end face of the plate.

Product quality control

At the base of the well, a serious task is to be a support and protection against penetration. ground water, therefore, the bottom slab must be of high quality and impeccable actual concrete condition. Cracks with a width of more than 0.2 mm on the surface of the plate X are not allowed. Products with exposed steel meshes and incorrectly located embedded products are also rejected. Steel hinges should not break behind the influx of concrete, so as not to burden the installation of plates. The release strength of concrete is 70% in summer, 90-100% in winter.

The geometry of the well bottom is not so important, but the straightness of the plate will ensure the minimum thickness of the seams and good shaft stability. Deviations from the standard for plate X according to GOST 8020-90 ± 5 mm in thickness, ± 6 mm in diameter of the bottom. The surface of the well bottoms should not have a large concentration of defects - shells, sagging, chips, delaminations. Otherwise, contact with liquid media and soils will quickly lead to wear of products.

Upon receipt of a batch of bottoms, it is necessary to conduct a complete inspection and acceptance tests. According to GOST 8020-90, they include an assessment of factors:

• Concrete class for strength and tempering strength of concrete;
• Compliance with the provisions of reinforcing and embedded products;
• Strength of welded joints;
• The thickness of the protective layer of concrete to the reinforcement;
• Geometric conformity to the standard;
• The actual state of the concrete.

The supply of reinforced concrete for the construction of wells is accompanied technical passports, in which the consumer is informed about the date of release of the bottoms, the characteristics of concrete, the class of water resistance and frost resistance, the type of steel and the anti-corrosion protection of products. In the Complex-S company, you can buy only certified well bottom plates, which will be accompanied by all the necessary documentation.

Transport and storage

Even items as simple as slabs and well rings require special handling upon delivery. Company "Complex-S" will deliver concrete goods promptly and carefully. Round concrete slabs are stored on a leveled base, on spacers, in stacks no higher than 2.5 meters front side up. When transporting the bottom of the wells, they are securely fixed and laid according to weight, with the obligatory use of gasket material with a thickness of at least 3 cm. Loading and unloading concrete slabs requires accuracy and care, in this case, the product will “reach” the installation, retaining maximum strength and reliability.

Well bottoms (bottom plates) PD 10 bottom plate are a prefabricated element that is designed to prevent runoff water from entering the ground and groundwater from entering the well system. They are used in water, gas, sewer wells, as well as in the arrangement of drinking wells, septic tanks and cesspools. Products are suitable for use in dry and moisture-saturated subsiding soils.

The reliability of the entire structure depends on the quality of the bottom plate and the correctness of its installation. well bottom PD 10 bottom plate designed to withstand any load despite ground movement and groundwater influence. The size of the product is selected in accordance with the size of the rings, covers and manholes.

Advantages

• High level of strength and durability finished products thanks to the use of high quality materials
• Quick and easy installation due to precise overall dimensions
• Resistance to lateral, static and dynamic loads
• Simple, labor-intensive maintenance and cleaning
• Products are suitable for any type of soil

The slab of the bottom of the well is a reinforced concrete product of a rounded shape. The diameter of the bottom must not be less than the diameter of the outer ring. There are several modifications of plates, differing in height, diameter and weight. For their marking, an alphanumeric designation is used. The selection of modifications is recommended to be carried out with a specialist in order to avoid incorrect calculations.

Specifications

• In the manufacture of the bottom slab, heavy concrete class B15 (M200) is used
• The frost resistance index of concrete is F100
• The water resistance index of concrete is W4
• Reinforcement is carried out with steel of class Bp-I or AI-AIII
• The products are equipped with mounting loops made of class A-I steel
• To be able to use the elements of the well in an aggressive soil environment, in concrete mix sulfate-resistant cement is added, which tolerates reactive and chemical substances well.

Location selection

Before starting the construction of the structure, it is necessary to determine the location of its location. The site must be convenient for operation. During the construction of a water or sewer well, it is imperative to calculate its volume, depending on the daily need for water and drainage.

Mounting

Well bottom plate PD 10 bottom plate is lowered into the shaft first and placed horizontally. After it, wall rings are installed, which are covered with a well cover and a hatch. The joints between the bottom and the wall rings are carefully sealed with a mortar with the addition of cement.

The bottom must be installed evenly, on a prepared pad and a concrete base that ensures the stabilization of the structure. Otherwise, distortion may occur, which will lead to the appearance of cracks and a violation of the sealing of the well. Before installing the well bottom, it is recommended to examine the soil and determine the depth of the groundwater.

The mark of the axis of the well is verified using a level. Sometimes during installation a slope is created towards the outlet pipe in order to avoid the formation of excess water in system. Do not forget about the additional waterproofing of the bottom of the well.

The bottom slab bears the weight of the entire structure, therefore it is made of heavy grades of concrete that are resistant to corrosion, moisture and impact. low temperatures. The product is reinforced with steel rods.

Indicators for which acceptance tests are carried out

• Brand and class of concrete in terms of compressive strength and tempering strength
• Concrete surface quality
• Concrete cover thickness to reinforcement
• Correspondence of metal and embedded elements
• Strength of welded joints
• Geometry Correctness

Quality control

It is obligatory to have a technical passport (certificate), which indicates the date of manufacture, the brand of concrete, the compressive strength of concrete, the water resistance and frost resistance of concrete, the results of acceptance tests.

On the surface of the products, shrinkage cracks with a width of not more than 0.1 mm are permissible. Deviations in geometry should not exceed 5 mm in thickness and 6 mm in diameter. Permissible a small amount of shells with a diameter of not more than 15 mm and a depth of up to 5 mm. Mounting loops should not be hidden behind concrete sags, as this may make installation difficult.
