Question/Answer

- Delivery price?
Delivery is calculated based on the distance of your facility, from the warehouse, as well as the tonnage and dimensions of the products.

-Where are you bringing it from?
Delivery is carried out directly from production. Production facilities are located throughout the central region, and before entering our network, they undergo strict quality control by the legal, accounting and quality departments.

- Where is the post office?
For the convenience of users, we have created a system for distributing the load on managers; if 1 person checks the mail, this significantly slows down the work or even leads to the fact that read letters are lost. You can leave a request through the form at the top of the site “Leave a request”, it will go to a free manager and they will call you back within 5 minutes.

- Do you have a mobile number?
For the convenience of users, we have created a system for distributing the load on managers; if a mobile phone is specified, then only 1 person can talk on it, and it will be difficult to reach him during the season.

- Why is it so expensive?
The price of a product consists of several components, the main one being the cost of the material, which determines the quality of the final product. There is also a markup from the factory and a markup from the trading company, we work on the terms of a dealer discount, so we don’t have a markup separate from the factory, we make money from the fact that the factory shares part of its profit with us, and we, in turn, provide the factory with volume to ensure uninterrupted operation .

- Why can’t you order less than 15 thousand? Do you work only in wholesale?
Some items are manufactured in nearby areas and shipping of these items adds significant cost to the product. We calculated that when ordering more than 15 thousand, the benefit from purchasing products from us becomes greater. If you have a small request for products that are manufactured in your area, it will be cheaper to purchase products at nearby factories. Unfortunately, at the moment we do not have a single plant in the Moscow region that has passed our quality check.

- Where can I pick it up?
The products are manufactured in different factories, region and city, the manager can tell you, because the factory is different for each product.

- Why is delivery so expensive?
Delivery is calculated based on the distance of the object from the factory warehouse. The delivery cost is divided by the number of items based on the weight of the product; if you order 1 item, the entire delivery cost will fall on it, but if there are 10 items in the order, the delivery price will be equally distributed over these 10 items.

- Do you work with VAT?
Yes, the company Beton Project LLC works for OSNO and is a VAT payer. All prices on the website include VAT.

- Why is only the office listed on the website and not the plant?
We are a dealer of factories and operate at our office address. Because Our list contains a significant number of factories that have passed our inspection; it is not rational to post all the addresses of factories with products, which would complicate the search for the right factory. If you are interested in where this or that product can be exported, you can always check with the Manager or use our delivery.

- Do you have a warehouse in Moscow?
We do not have a warehouse in Moscow or the Moscow region, because... this will have a negative impact on the cost of the product because it will entail additional costs.

- What kind of plant? What's it called?
The products are manufactured at different factories, you can always come to the factory and see for yourself the quality of our products. Also, if you have any doubts, you can pay for the products directly to the factory.

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

Explanation of markings

The marking of support and unloading plates contains alphabetic and numerical designations that determine the name of the product and its standard 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, for rainwater inlet;
• PD – support plate, road;
• 6 – standard size of the product;
• PYAP – anchor plate, rectangular;
• OUP – universal support rectangular

Reinforced concrete base slabs are made of heavy high-strength concrete, according to the sketches of the Mosinzhproekt State Design Institute in accordance with GOST 8020-90 “Reinforced concrete products for manholes for water supply and sewerage networks”, working drawings of the 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.

Well road slab ( PD 10 – reinforced concrete structural element of round underground wells, on which the well hatch rests, located on the roadway. Together with other well elements, support plates are often used in road construction when laying urban communications - drainage, network, water and gas wells, different lines communications. Strict requirements for road surfaces are also presented to the plate. Norms and standards for the production of well road slabs are enshrined in GOST 8020-90.

The slabs have a rectangular shape with a recess for supporting the well cover and a hole corresponding to the diameter of the well. The presence of a road slab allows you to reliably fix the hatch and well in its position, eliminating deformation from vehicles passing through it. The PD 10 road slab is made of high-strength heavy concrete reinforced with prestressed reinforcement, which significantly increases its performance characteristics and guarantees high wear resistance. Due to reinforcement with steel frames of class At-IIIC and At-IVC and A-I, A-II and A-III and an increased thickness of 220 mm, the slab acquires a mass of 2647.5 kg. This weight is mounted and lifted using mounting loops using cranes.

Due to the use of heavy concrete grade M200, the road slab for wellsPD 10 is characterized by strength, durability and high corrosion resistance. The moisture absorption of concrete is no more than 8% of the design mass. The grade of concrete for frost resistance of the base plate is not lower than F50, water resistance is not lower than W2. Road base plate plays an important role in road construction as it prevents subsidence road surface in the area of ​​the well and contributes to safer movement of various vehicles through such areas. For maximum safety, it is imperative to install the well elements so that the well hatch cover is flush with the surface.

Product marking

Like other reinforced concrete products, road slabs PDs are marked with alphanumeric groups. The first group indicates the type of product, then (rounded to the nearest whole number) indicates (in decimeters) the diameter of the hole.

The second group carries additional information - the indicator of concrete permeability: (N - normal, P - reduced, O - especially low) and special design characteristics (embedded products, holes, niches and cutouts), indicated by Arabic numbers or letters.

For an example of marking a road slab, consider PD 10 (2800x2000x220mm), where:

• PD – well element type – road slab;
• The number is the diameter of the hole;
• The letter is the permeability of concrete.

The symbol, weight and date of manufacture of the reinforced concrete product are located on the outer side surface of the PD base plate.

Product quality control

The main reason for the rejection of slabs, as well as other reinforced concrete products, is the exposure of working reinforcement. Due to such a defect, the product very quickly corrodes and crumbles during operation, which can threaten road safety.

For any concrete slabs the absence of cracks is important. Only shrinkage cracks barely visible to the eye with a width of no more than one tenth of a millimeter are possible.

Minor deviations in the geometric parameters of the base plates are allowed, no more than ±5 mm in thickness, ±6 mm in the length of the slab. The surface of the road well slab PD should not have large quantity shells with a diameter of more than 15 mm and a depth of more than 5 mm.

Acceptance tests carried out when checking indicators:

• class of concrete in terms of strength and tempering strength of concrete base slabs;
• compliance of reinforcement and embedded products;
• strength of welded joints;
• thickness of the protective layer of concrete to the reinforcement;
• accuracy of geometric parameters;
• quality of the concrete surface of the slabs.

Accompanying a batch of road concrete slabs for wells technical passport, must contain information about the date of manufacture of the batch of concrete slabs for PD 10 wells, the number of products, and the results of strength tests; information about the grade of concrete and compressive strength, as well as the class of concrete for frost resistance and water resistance.

Transportation and storage

Well slabs must be stored in stacks in working position (face up). One stack should not be more than 6 rows in order to avoid falling and deformation of products. For transportation, road slabs are stacked no higher than 2.5 meters and securely fastened. Both during transportation and storage, gaskets with a thickness of at least 40 mm must be placed between the plates.

Concrete round well bottoms PD 15-1

The underground sections of the city are pierced by vital systems: gas pipelines, sewerage, water and heat supply, drainage, etc. Therefore, back in the Soviet period, materials were designed to quickly create wells - trunks for rapid penetration into the network. In addition to public utilities, wells were dug in private households, agricultural and industrial enterprises.

Due to factory readiness and low price, by purchasing wall rings, bottom slabs, 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 KS rings. And the bottom is made of KCD, PD plates. Sometimes, a developer tries to save money and buy rings with a glass-shaped bottom. Design drawings of universal products for water management construction include the project Series 3.820-9 issue 1.

Well bottom slabs - characteristics, dimensions, price

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

The diameters of the bottom plates depend on internal diameter 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. All sizes of slabs, trays, well rings, well covers can be found in the catalog "Reinforced Concrete Products Directory". The panels are expected to be strong, rigid and crack resistant, and not to overgrow or rot.

A high-strength reinforced concrete element serves as the basis for underground water supply and sewerage wells; often bottom slabs are used as a support for private systems, various cellars, cesspools, agricultural buildings, and 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 purchased for the construction of brick and stone walls wells. The diameter of the bottom corresponds to the diameter of the well from 1000 to 2000 mm. Minimum diameter installed at least 80 cm so that, if necessary, a person can get inside. The operation of well bottoms is permissible in any climatic conditions, in dry and water-saturated soils.

Application slab products

Modern standard album series 3.820-9 issue 1 includes only elements of round wells, which are installed everywhere for a variety of purposes. The main goal of the designers of concrete slabs was versatility - the standard album PD 15-1 included only five standard sizes of slabs that satisfy all construction needs. In 2017, the production of well products is determined by the new GOST 8020-2016, you can download it for free in the “GOSTs and SNiPs” section of the website.

PD type slabs are also called KCD - cylindrical well bottoms. They are laid at the very bottom of the well and become the basis for the subsequent construction of the well trunk. Series 3.820-9 does not require the presence of well chambers, so the wall rings of the wells are mounted directly on the bottom. The task of slab products of type PD 15-1 is stability and insurance of well rings from shifting and subsidence.

Dimensions, loads and requirements for the production of well bottoms are specified in GOST 8020-90“Concrete and reinforced concrete structures for wells.” Similar products include the release of 7 series 3.900.3 and in the project series 3.900.1-14. Universal well bottom slabs can serve 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, and liquid media of varying aggressiveness, concrete for the production of bottoms is selected with reduced permeability. The water absorption of such PD 15-1 slabs is no more than 8% by weight. The water resistance class for ordinary products is set to W4; if you need to buy bottom plates for working in aggressive environments, it is recommended to order plates of a higher class. The frost resistance of concrete well bottoms is established according to the intended construction region (at least F100). Production in Khabarovsk, Omsk, Krasnoyarsk, Ulan-Ude, Irkutsk, Sochi, Stavropol is adjusted to climate needs by modeling necessary indicators protection against temperature fluctuations.

To prevent erosion, wear and corrosion, the manufacturer carefully protects PD 15-1 slabs. The production of well bottoms from heavy grade concrete M200 (B15) ensures that GOST standards are met in terms of strength, rigidity and crack resistance. The quality of the bottom ring plates is controlled at each stage of production and then tested in laboratory conditions. Reinforcement of the bottom slabs is carried out with welded mesh made 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 undergo a production stage of anti-corrosion protection. To increase the service life of well bottoms, it is necessary to hydrophobize and insulate the seams and the products themselves. The price list for well elements for 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, and since then reinforced concrete products have been actively produced according to the 3.820-9 series. Today, technologists at reinforced concrete factories pay attention to the quality and characteristics of the recipes concrete mixtures. Therefore, before ordering bottom slabs and well rings, it is necessary to indicate the required water resistance and frost resistance class of concrete. The weight of the PD 15-1 bottom plate is 925 kg, this allows it to be well anchored in the ground and avoid shifting even during vibrations. Installation of well bottoms is carried out on a sand base and a layer of mortar 100 with a thickness of at least 10 mm. At the Kompleks-S company you can buy well bottom slabs 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.

Marking of bottom plates

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 a well PN 10 (1500x1500x100 mm), which can also be called KCD. PN – bottom plate, 10 – well diameter 1000 mm. The brand, weight, production date and QC stamp are applied to the end face of the slab.

Product quality control

The base of a well has a serious task - to be a support and protection from penetration groundwater, so the bottom plate must be different high quality and the impeccable actual condition of the concrete. Cracks wider than 0.2 mm on the surface of slab X are not allowed. Products with exposed steel mesh and incorrectly positioned embedded products are also rejected. Steel hinges should not be torn off due to the influx of concrete, so as not to burden the installation of slabs. The tempering 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 slab will ensure a minimum thickness of the seams and good stability of the trunk. Deviations from the standard for plate X according to GOST 8020-90 are ±5 mm in thickness, ±6 mm in bottom diameter. The surface of well bottoms should not have a large concentration of defects - cavities, sagging, chips, delaminations. Otherwise, contact with liquid media and soils will quickly lead to wear of the products.

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

• Concrete class based on strength and tempering strength of concrete;
• Correspondence of the provisions of reinforcement and embedded products;
• Strength of welded joints;
• Thickness of the protective layer of concrete to the reinforcement;
• Geometric compliance with the standard;
• Actual condition of concrete.

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

Transportation and storage

Even simple items such as slabs and well rings require special handling upon delivery. The Kompleks-S company will deliver concrete products quickly and carefully. Round concrete slabs are stored on a leveled base, on pads, in stacks no higher than 2.5 meters, face up. During transportation, the bottoms of the wells are securely fastened and laid according to weight, with the obligatory use of cushioning material at least 3 cm thick. Loading and unloading concrete slabs requires accuracy and care; in this case, a product that has retained maximum strength and reliability will survive installation.
