Trenchless technology

Features of laying the main pipeline

Today, pipeline systems pervade almost all areas of production and industry. Pipes transport both liquid and gaseous substances. Equally important is reliable separation. Therefore, most often pipes are laid underground or under water. The laying of main water supply pipelines plays a particularly important role. It is carried out in areas with different climatic and geological conditions, which may lead to different laying options. In this case, additional factors such as reduced tees are inevitably used. If you need to create a branch from the main pipeline, you should reduce the tee.

When laying the main water pipes, special coatings are used to protect the surface of the pipes from corrosion. They are applied both outside and inside. HDPE tees can be used for plumbing. If we are talking about the internal laying of the room, then it is performed in an open way, for example, along the walls. However, water supply is often not allowed due to room conditions. After that, the procedure is transferred to a common channel, where all other pipelines are laid. However, such combinations are possible only if the channel is passing. Permits and justifications are required to lay main water pipes in special channels.

Trenchless technology

Called NO-DIG or TRENCHLESS TECHNOLOGIES in the world, NO-DIRECTION TECHNOLOGIES are a variant of underground construction work that does not open the ground.

Trenchless techniques are used in the following types of work:

  • laying of communication cables;
  • underground laying of electrical cables;
  • laying of oil, gas and heat pipelines;
  • laying sewer and water pipes;
  • Vertical use – for the formation of piles and pile structures, wells and wells.
  • Replacement of pipes – destruction of the old and simultaneous laying of the new – according to European standards.

With trenchless technology, approximately 90% of all work is done underground, eliminating the need to restore road surfaces and disrupting the normal rhythm of city life (such as blocking highways or (without interrupting the communication of the Trenchless technology is more economical (2.5-3 times) and environmentally friendly compared to traditional (trench) methods.

A machine for drilling wells and plugging pipes (pneumatic puncher)

Well punch
Wells are formed by single (without expander) or multiple (with expander) penetration of pneumatic punches from the initial well to the receiving well.

Cable laying is performed when the well is punched with a forward stroke. If you use an additional device, it will run in the opposite direction of the machine.

Pipe laying
Pipelines are laid in pre-punched wells or attached to pneumatic punches and pulled into the wells during formation. As the air punch progresses, the pipes pile up in the inlet pit. In some cases, it is recommended to tighten the pipes into pre-drilled holes.
