Concrete pipes - types, characteristics and use

Pipes

We are so accustomed to all sorts of objects on the sides of roads and in the city, that sometimes we simply do not notice them. Today in the article we will talk about the sewage system, which often uses concrete pipes used or new to drain various wastewater. In this case, it will be a question of the road variant and the socket form.

Non-pressure pipes for various uses

Road

This type of concrete products is designed for laying automotive and railway coatings, so they got their name. If we take into account the classification, such pipes refer to non-pressure structures.

With their help, you can create:

  • sewage;
  • livnestok;
  • underground collectors;
  • non-corrosive production liquids.

Properties and production

Due to the harsh operating conditions, concrete road pipes under the coating should have:

  1. Resistance to deformation, cracking and bending;
  2. Resistance to soil and atmospheric moisture;
  3. High specific strength:
    • unlike other similar non-pressure pipe structures, it is reinforced. Thus, they manage to withstand the loads of various vehicles, freight trains and passenger cars;
    • For this purpose, reinforcement of pipes with high-strength steel of grades BP-II and B-II is used;
    • in the manufacture of products used heavy concrete.

    Tip: the finer the granularity of the concrete used, the more accurate the geometrical dimensions of the products and the smooth surface can be. This parameter prevents silting of the inner surface of the pipe.

    Vibration compaction helps to improve the frost resistance and water resistance of products, due to which air pores are removed. There is a direct relationship between these parameters, based on the fact that the less the material will be impregnated with moisture, the less will be the level of microdestruction of its surface during freezing.

    The weight of road concrete pipes is significant, which ensures their resistance to ejection forces during floods and frost heaving. Due to these characteristics of the product it is possible to install at depth.

    Laying concrete sewer

    Not the last role is played by the thickness of the walls, which ensures their wear resistance. This makes it possible to operate structures for over a hundred years.

    Classes There are four groups distributed over the maximum depth (or embankment height) and level of strength, up to 5, 10, 15 and 20 m. The last two parameters are distinguished by reinforced reinforcement.
    Marking and dimensions
    1. Culvert pipes used in road construction designate "TV".
    2. The first two digits of the marking indicate the dimensions (in cm — the length and in dm — the inner diameter), and the last for the class. For example, TV 200.70-4 is deciphered as follows:
      • non-pressure pipe road culvert length 2000 mm;
      • internal O700 mm;
      • used in embankments up to 20 m high (fourth grade).

      Usually the length of the products is in the range of 2500-5000 mm, and the internal O500-2000 mm.

      The price of pipes used in road construction directly depends on their strength characteristics and workmanship - the cost of concrete goods will be higher, the higher their size and strength. When choosing the optimal ratio should be taken into account the minimum design strength.

      Using

      1. In road construction non-pressure pipes used for the construction of embankments.
      2. They make gutters under the highways and railway canvases.
      3. They are used to lay roads over small streams, rivers, canals and over ravines.
      4. In public utilities, they are used for microtunneling.
      5. In settlements built tunnels for cable networks, heating, water supply and drainage.

      Tip: the construction of underground tunnels in the future facilitates operational inspections and repairs.

      Conclusion of urban sewage

      Flange

      One of the types of concrete pipes - bell-shaped, well-proven in construction work. With their help, it is possible to lay underground pipelines for sewage for various purposes.

      They differ in that complete with them are special rubber rings that serve as a seal during their docking. Thanks to them, the labor intensity and cost of installation is significantly reduced.

      Rubber joint seal ensures leak tightness

      They give the opportunity to spend it with quality and in a short time. In addition, you will be confident that the pipeline will be tight and reliable.

      The industry offers two options for these products, which will be discussed in more detail below:

      Pressure head
      1. Used for the construction of underground pressure piping.
      2. They can be not only bell-shaped, but also cylindrical.
      3. The instruction allows non-aggressive liquid to be pumped at temperatures of up to 400 ° C.
      4. Section - round.
      5. Connection method - end-to-end, rubber ring serves as a seal.
      6. Abbreviation - TN. When equipping the product with a core of polymer - TNP, of steel - THC.
      Free-flow
      1. For the production of used concrete class B25.
      2. Included are rubber o-rings.
      3. Diameter - 400-1600 mm.
      4. Used for laying underground gravity collectors in a wide range of business and industry.

      They are allowed to be used for the transportation of aggressive liquids, however, at the same time, the strength characteristics of the products must be at a very high level.

      Bell pipes have an abbreviation of TBR - their one end is somewhat extended. Pairing with another pipe occurs at the expense of him.

      Tip: the installation is best done with the help of construction equipment, since the weight of the products is significant and you cannot do it yourself.

      Benefits, Types and Uses

      These products are different:

      • strength;
      • frost resistance;
      • high corrosion resistance;
      • ability to stay smooth for at least half a century.

      Depth of laying or filling with soil - up to 2, 4 or 6 m.

      There are 4 types of such products according to GOST, they are all cylindrical and differ in the method of splicing:

      • T-sealed sealant;
      • TB - sealed with rubber rings, at the end there is a stop rim;
      • TC - step interface;
      • DFT - has a sole for mating in the area of ​​the joints.
      Concrete products brand TC

      Products have earned their prestige over the years, so without them it’s hard to imagine:

      • underground pipelines not subject to water pressure from the inside;
      • systems of storm sewage and removal of human life processes at work and in everyday life;
      • road construction;
      • drains of various designs;
      • storm sewer;
      • land reclamation work;
      • device engineering communications, passing under the highway or railway tracks.

      Conclusion

      This article has been considered concrete pipes, which are used in various industries, in particular, road and socket. The first ones, due to their specificity, are an enhanced version of standard products, which enables them to withstand increased loads.

      The latter are more used in general business activities. Both options have a lot of advantages, one of which is durability. The video in this article will help you find additional information on this topic.
