The manufacturer of high-quality reinforced concrete products "ZhBIKOM" from Moscow provides its customers with an improved model - the UOP 6 base plate for wells. Made from durable material, it is able to withstand intense long-term loads, temperature changes and the influence of aggressive chemicals.
The main purpose of the base plate is to provide access to the well from the surface. A cast iron hatch is always installed at the top of the product. Installation is carried out on rings of wells of various shapes, followed by laying the road surface. The reinforced base plate UOP 6 is used in the construction and organization of access to:
The main requirement that ZhBIKOM customers make in Moscow is high concrete strength and protection from external influences.
All products that you can buy from our company comply with national GOST standards with a precise classification of all products. However, this did not prevent us from improving the design of the unloading base plate UOP 6:
The base plate UOP 6, the price of which is quite affordable at the ZhBIKOM company, has the following dimensions:
These data are established by standards and generally accepted rules for organizing wells on busy highways and highways. Attaching the base plate to the well can be done either by simply installing it on top or using cement mortar.
In the construction of low-rise private houses, multi-story buildings, and industrial facilities, the following slabs are used:
They form the basis of buildings. During the construction of roads not only for ground transport, but also for air transport. The plane puts a lot of load on the runway, and a concrete slab can handle it. In this case, the following types of coatings are used:
Road ones are constantly being improved. They perfectly solve problems when efficiency and reliability are needed. When constructing reinforced concrete fences, you cannot do without concrete slabs. Although they are not so in demand.
For more effective use of concrete structures, you need to know their positive and negative sides. Advantages:
Flaws:
Concrete slabs are divided according to the following characteristics:
They are monolithic structures reinforced with a steel frame. They mainly perform a load-bearing function, distribute loads and ensure the rigidity of the building. Manufactured at the factory or on site. This process occurs by pouring the reinforcement with a precisely calculated volume of concrete. The reinforcement inside provides a large margin of safety. The ratio between reinforcement and concrete is calculated in (m3).
Advantages of this type:
Flaws:
Remember: additional strength is required in support areas.
It is used in the construction of massive structures, heating mains, remote structures (balconies).
Ribbed slabs PTR. - this is a solid product with ribs (U-shaped) in one or two vertical directions. The main areas of application of these slabs are industrial buildings, utility rooms for various purposes: garage floors, attics, basements. The unsuitability for the construction of residential buildings is due to the presence of protrusions that do not allow for a flat ceiling.
Advantages:
Flaw:
The reinforcement runs on one side.
These slabs have voids inside the structure. That is why they are called empty. The shape of the voids is round or oval.
Advantages:
Flaw:
Suitable for almost all types of construction (entertainment centers, cottages, garages, warehouses) They are used as internal floors.
Prepared from the most durable grades of concrete. Serve as the basis of buildings. Primary requirements:
Separate the floors of the building. They have the widest range. Traditionally used - M300. M150 is suitable for low-rise buildings. The versatility of these slabs makes them the most popular in construction. The advantages of such floors:
Reinforced concrete road slabs. They occupy one of the leading positions in production. Widely used in the construction of highways, highways, and roads. In production it is used (B25, B30). The use of road slabs increases the durability and reliability of transport routes. Main advantage: withstands high loads without losing its shape or mechanical properties. Reinforced reinforcement increases its stability many times over and is used in the construction of runways.
They are made by vibration casting or vibration pressing. After this, the next stage is steaming until the concrete mixture is completely crystallized. Different colors come from natural impurities. They do not fade or wash off over time. Advantages:
External wall panels. Help speed up the pace of construction. They are used in the construction of external walls of buildings. Widespread use is due to a number of advantages of these panels:
They are the most complex element in building structures. Classified:
Although base plates They are an invisible part of a reinforced concrete structure; they are entrusted with the main task of ensuring strength during the construction of the facility and its communication systems. What is the base plate used for? What are its functions?
The main task that this (and very important) part of the structure solves is relieving the load from other components of the facility. This usually applies to the sewer well, heating system and water supply. In addition, in any engineering project there are exit options for carrying out repairs on the site. And thanks base plate ensuring proper maintenance and safe access to these systems.
Support reinforced concrete slabs are used in the construction of low-rise and high-rise buildings, drawing up projects for household and administrative facilities to ensure the strength and reliability of the structure being created. In this case, both bricks and large blocks can be involved in the work. In this case, the main task of the slab will be to uniformly distribute the load of the transverse and longitudinal girder on the wall masonry.
Varieties
There are various types of op boards, which are more or less in demand in the construction market. The most popular and most often used of them are reinforced concrete structures such as support-anchor plate And base plate op. They act as a construction basis not only for the foundations of objects, they are also indispensable in modern underground communications.
Depending on the area of use, the boards used must have high technical characteristics. This is controlled by strict GOST rules. Such technical requirements are explained by the fact that very often base plate OP participates in the creation of load-bearing structures of buildings.
There are separate types base plates, used in laying railways and highways, heating mains, etc.
Suitable for blocking wells base plates OP-1d OP-1k and UOP-6. All these types of base plates differ in their design features.
In the case of the model base plate op 1k, which is a short slab, protects the well of communications running through roadways. The side length of the op-1k base plate is 1600 mm. If we compare it with the product slab op, then its side difference will be 1000 mm. Thanks to the impressive dimensions of the product and its shape, reminiscent of a truncated pyramid, it distributes the load over the entire working surface, which in turn ensures safe operation and prevents premature destruction of the well. This modification op slabs thickness 25 cm. In addition, it has a round through hole for the lid. The presence of a built-in hatch simplifies the installation process. Most often used for conventional cast iron hatches. A slab OP-1d, being an elongated version of the first modification, has a thickness of 16 cm and a rectangular through hole for a drainage grate, which is used to arrange a drain, that is, this is the so-called hole for a “rain inlet”. That is, depending on their purpose, they are used to increase the strength of wells. The choice is determined by operating conditions. But both models are indispensable in areas with weak soils and difficult hydrological conditions. At the same time, they protect the entrance to the well from destruction due to squatting of the soil. But their use is permissible on low-intensity road surfaces in the absence of an aggressive environment.
Reinforced base plate UOP-6 is the key to the longevity of the communication system. Its shape is represented in the form of a truncated cone or pyramid, in the center of which a through hole is made, created for the purpose of constructing wells.
Unlike previous models, this one is presented in the form of a reinforced concrete ring with a shell for a well. Its special design allows protection in all required areas, including increased external overloads. Such a slab is applicable on intensive, significant routes with heavy vehicles, as it has increased strength, capable of withstanding a load of several tens of tons. It is also applicable for telephone and unified wells. In addition to high resistance and reliable strength, its technical advantages also include enhanced frost resistance and moisture resistance, which significantly extends its service life. This happens thanks to the anti-salt waterproofing impregnation that is used to treat its surface. The mass of the slab is 0.8 tons with a diameter of 1.7 m
There is also support-anchor plate, which has additional iron inserts to attach anchor bolts. Due to this fastening, the slab is so firmly fixed in place that it cannot be moved later by any mechanical means or by soil sliding due to heavy rains. This board can stick to almost any surface. Therefore, it is beneficial to use where the highest reliability data from the concrete base is required.
What are the advantages of a base plate?
Proof of these practical advantages that distinguish our slabs is their long service life.
How to install the base plate correctly?
In order to ensure the decent quality of the installed slab, you need to follow a number of installation rules. Direct installation occurs in two ways:
In any case, during installation it makes sense to adhere to the maximum load capabilities, because if it is exceeded, this will inevitably result in early wear of the product.
There are certain conditions that must be met during assembly:
It is imperative to carry out preliminary preparatory work, including cleaning and subsequent wetting of the surface. Afterwards you need to treat it with hot bitumen liquid.
A compacted base is being prepared with a foundation made from a special dry mixture
A corresponding base plate and ring are placed on this base.
The last thing to do is seal the area where the ring meets the slab. The required level of sealing can be achieved thanks to the conveyor belt, as well as a special porous sealing gasket.
What is special about the base plate manufacturing process?
Formation base plates is an important process that requires responsible control - after all, they represent a very important design detail. Therefore, an integral part of this material is concrete grade M200, which is intended for use directly in installation on wells and is able to withstand operation on the roadway. If the product will subsequently work in bending, then it is customary to take concrete that has tension.
This plate is distinguished by a very complex technological production procedure. It all starts with steel rods placed in special molds and filled with concrete. In this case, by heating or using a regular jack, all existing reinforcement is stretched. And as soon as the product hardens, evaporation begins. To do this, reinforced concrete slabs are installed in special heat chambers, where all the liquid evaporates from them in twelve hours at a temperature of 90 C. As soon as the required strength is achieved, the rods are weakened. When they contract, they create corresponding tension. Despite the technical difficulties of the creation process, they can be purchased at fairly affordable prices.
Today the need for base plate remains at a high level in various regions of the country, since, despite the harsh conditions of our climate, it ensures reliability and strength of communication for many years.

Support slabs are components of engineering structures that are used for the construction of prefabricated wells. Reinforced concrete wells are structures that are used for the construction of various types of underground communications: sewer, water supply, gas networks and inspection wells.
A feature of the slabs that distinguishes them from support rings is a special rectangular shape, which allows you to direct loads to the entire perimeter of the slab, due to which the walls of the well receive minimal load, which has a beneficial effect on the service life of the entire structure. In addition to the main function, the slabs allow you to bring the well cover to the required level, protect the well from debris, entry of unauthorized persons, soil collapses, and provide a reliable and durable base for the hatch. Reinforced concrete support slabs for wells are designed for heavy loads, which is why they are used, among other things, on roads and highways.
Base plates are used in areas such as road and engineering construction, in the construction of sewer wells and stations, fire and treatment tanks, tunnels, sewers and mines. The data is widely used in the energy sector, during the storage and refining of oil, gas, mineral fertilizers and hazardous substances, as well as in the food industry (bunkers and elevators) and in electroplating production. Wells made of reinforced concrete prefabricated products can be used at high groundwater levels or in soils with a seasonal rise.
Concrete reinforced with steel frames, from which the base plates of wells are made, has a number of advantages compared to other building materials. The strength of concrete allows wells to withstand the load that occurs due to soil pressure, and its dense structure is not subject to erosion by groundwater, thanks to which reinforced concrete wells can be used in most soils. The smooth surface of the rings does not allow debris to cling to the walls and form blockages. In addition, concrete is easily cleaned, and cleaning does not require special equipment or qualified specialists. Elements of prefabricated wells are easily mounted on top of each other. Thanks to this, repairs do not require a complete replacement of the structure - it is enough to simply replace or repair the worn-out element. Inertness is another of the most important advantages of concrete; thanks to it, the products do not have any effect on the quality of water and, accordingly, can be used for storing drinking water.
Structurally, the base plates are a rectangular plate with inclined edges and an outlet hole in the middle, round or rectangular, which is subsequently closed by a cast-iron hatch. As a rule, rectangular support plates are installed on wells that are located under busy highways, that is, in places where there are significant non-uniform loads.
Reinforced concrete base slabs are manufactured in accordance with GOST 8020-90, as well as series 3.900.1-14 issue 1 “Reinforced concrete products for round wells for water supply and sewerage” and RK 2201-82 “Prefabricated reinforced concrete wells on underground pipelines” from heavy concrete, Compressive strength class is accepted as B15, B20 or B22.5. The frost resistance class of concrete is accepted to be no less than F100. The water resistance class must be at least W6. To increase the slabs' resistance to moisture, additional hydrophobic protection is added to the concrete products.
Various types of foundations are used for the construction of houses and outbuildings. Monolithic reinforced concrete slabs are popular, providing stability, strength and durability of buildings. Slab foundations in construction are used for weak soils susceptible to frost heaving. After preparing the site and constructing a cushion of crushed stone and sand, the formwork is installed. Then a layer of waterproofing is laid, and the monolithic base is reinforced. The construction of the slab is completed by the process of pouring cement. Each stage has its own characteristics.
A monolithic reinforced concrete base, as well as a prefabricated foundation made of reinforced concrete slabs, are made from heavy concrete mortars, to strengthen which reinforcement is used with a diameter of 8-12 mm. To decide on the use of a monolithic slab as a foundation, special calculations are performed.
The thickness of the foundation is determined, as well as its depth, depending on a number of factors:
The monolithic structure is durable and is used on the following types of soil:
A distinctive feature of the foundation slab is its increased area, which allows:

Foundation type: monolithic reinforced concrete slab - a responsible structure with certain characteristics:
Monolithic reinforced concrete slab has increased strength An important characteristic of the foundation is its overall dimensions. The length and width of the foundation structure correspond to the dimensions of the future building, and the thickness varies within wide limits:
The characteristics of the slab base are influenced by the brand of concrete mixture used, the range of reinforcement, as well as the type of foundation structure.
Compared to other types of foundations, a monolithic reinforced concrete slab has serious advantages:
No special equipment is required to pour a concrete slab To carry out construction activities, no special training or special equipment is required.
In buildings built on a monolithic slab, the floor is concrete. How to insulate it? This question interests novice developers. There are many options involving the use of modern sheet heat insulators. The technology allows you to build a thermally insulated Swedish stove. This is also one of the advantages of the monolithic structure of a reinforced concrete foundation.
Along with its advantages, the foundation has weaknesses:
Despite the existing disadvantages, professional builders prefer slab construction due to its high performance characteristics.
The technological process of constructing a monolithic slab includes preparatory measures and basic operations. Let's look at the main stages of work.
When preparing to concrete the foundation of a reinforced concrete slab with a monolithic slab, a number of preparatory measures should be performed:
Before pouring the concrete slab, it is necessary to carry out preparatory work The technology also provides for the possibility of laying utility networks during the construction of the foundation slab.
Having completed the preparation, perform the basic operations for installing the slab:
Please note important points:
Start dismantling the formwork one month after the start of concreting.
Monolithic reinforced concrete slab is a proven design that ensures the stability and durability of buildings on problematic soils. When performing work, it is important to comply with technological requirements and use high-quality building materials. It is important to decide on the design option for the slab, taking into account the design features of the building and the requirements of the design documentation.
