They are available in different varieties, including standard, pressure, and non-pressure pipes, each with unique qualities like robustness, longevity, and resistance to external influences. To ensure correct alignment and connection and preserve system integrity, installing these pipes is a simple process that entails trenching, laying the pipes, and backfilling. To assist you in understanding their significance and application, this article will examine their various types and applications and offer a straightforward installation guide.

Main characteristics of reinforced concrete pipes

The following specifications are provided by GOST standards (state standards), which are followed in the manufacturing of concrete structural materials:

• absence of cracks on the walls outside and inside;
• parts with the designations TS, TSP, TBP, TB are equipped with rubber sealing rings to ensure the sealing of the butt joint.

At the end of the part, product marking is applied to the surface. They vary in length and diameter of round or oval cross-section, and they are produced with or without sockets. Because of the heavy weight of the products, special equipment is needed to install the communications.

Advantages and disadvantages of reinforced concrete pipes

Reinforced concrete cylindrical socket parts are now widely available and are frequently utilized in the assembly of highways for a variety of applications. Individual links are simple to connect and function as gravity-driven, non-pressurized structures for the natural removal of sewage waste.

• high strength;
• ability to work at low and high temperatures;
• special folds and sockets help in connecting individual links;
• the inner surfaces of reinforced concrete pipes are smooth;
• concrete has anti-corrosion resistance and is not afraid of decay;
• the material of the products is dielectric and resists the effects of stray currents in the soil;
• fire safety;
• long service life (50-70 years or more).

Concrete pipelines’ high strength enables them to support large loads. They are buried beneath highways and railroads because of this ability. Reinforced concrete pipes can be used in both hot and cold environments because of their resistance to temperature changes. In highly humid environments, they are employed in the construction of pipelines.

• large mass;
• destruction of the material in an aggressive environment.

Laying channels and routes with a big weight requires specialized equipment that cannot be done without it.

Types of reinforced concrete pipes

Reinforced concrete pipes are currently available for purchase:

• pressure;
• non-pressure;
• non-pressure socket;
• socket.

Liquid transportation canals are laid using non-pressurized products. During the manufacturing process, heavy concrete brands (B25 and above) are utilized. Concrete mix water resistance is W6, and frost resistance is F300. Products that are manufactured typically vary in length from 2.5 to 5 meters and in internal diameter from 400 to 1600 millimeters. A variety of civil and industrial construction applications use concrete links, with the exception of constructing canals beneath category I and II highways.

• strength group 3 — withstands backfill with soil to a height of 6 m;
• group 2 withstands the load of a soil layer 4 m thick;
• products of strength group 1 — 2 m.

They carry liquid because of the system’s slight (2–3º) slope. It is important to keep in mind that the liquid flow’s cross-section is 5% smaller than the structure’s diameter when performing calculations.

A socket is an extension of the pipe that is used in socket parts as a connecting element. The product’s other end is constrained. These components are utilized in the building of subterranean liquid transportation systems. This most frequently refers to building culverts and storm sewers beneath railroads and roads.

Centrifugation and vibrocompression are two processes used to produce socket products from heavy grade concrete. Pipe dimensions are as follows: internal diameter: 400–2000 mm, length: 2.5–5.5 m. Because of how simple it is to connect these reinforced concrete pieces when setting up gravity channels, they are the most widely used. High levels of joint sealing are achieved by connecting the sleeve stepped element and the socket surface with rubber rings.

Pressurized products are also made from high-strength concrete. These structures’ contents move under pressure produced by specialized pumps. The walls of pressure pipes are thick—up to 10% of their diameter. Drainage systems beneath transportation highways are built with the use of products. Does not apply to private farms.

Marking of reinforced concrete pipes

Products made of reinforced concrete are labeled according to their intended use. Letters and numbers are used for marking, which is applied to the socket’s surface or the pipe’s end.

The product label’s numerical representations show:

• the first characterizes the internal cross-section of the product;
• the second is the length of the reinforced concrete tubular product in decimeters;
• the last is the load-bearing capacity of the pipe.

For instance, the following is what the letters and numbers in the marking TB 40.25-2 signify:

• TB – there is a socket-shaped connection;
• 40 – the internal diameter is 40 cm;
• 25 – the useful length of the product is 2.5 m;
• Group 2, meaning the soil height is no more than 4 m.

Occasionally, a second letter is added to indicate the pipes’ resistance to specific substances and permeability:

• O – especially low permeability;
• P – reduced;
• H – normal permeability;
• Щ – resistance to alkaline agents;
• K — acid resistance.

Digital and typographic markings provide information about the product’s dimensions and attributes.
