Pipe ramming is a trenchless technology, wherein a steal or plastic pipe with its open side is rammed into the ground at the required depth. This process is done progressively: behind every 6 m long pipe segment a new one is added. After all pipe segments are rammed in, they are cleaned off spoils. The rammed pipe can be used for its intended purpose, or as the casing for smaller pipes or cables.

Two pits shall be prepared for the pipe ramming, whereas the ground surface between them remains intact.

Pipe ramming is the optimal solution, when:

the surface of the land shall not be damaged (as in the case when a road or railroad goes or a building stands above the planned communication lines, a dam is built up above, or when the existing landscaping shall be preserved);
maximal construction length is up to 60 m.

Pipe ramming is appropriate for installation of subsurface utility service infrastructure of various application. Pipes from 100 to 1400 mm in diameter can be installed. The technology is not suitable when the soil is filled with rocks or boulders, thus investigation of the soil shall be performed first.

Pipe ramming enables you to:
  • Complete project faster and easier – the pipe ramming method makes possible to lay out the pipes directly to a manhole or basement without cracking it. Also, the pneumatic tool is easy to handle and combine with a pipe of the required diameter.
  • Ensure comfort – by installing utility network this way, it is not necessary to disrupt or restrict road or railroad traffic.
  • Decrease pipeline installation costs – no junctions are required for pipe ramming. It is necessary to prepare only a small ground surface area, thus the environment restoration costs are lower.

Pipe ramming is well recognised in Lithuania and abroad. It is a safe, fast, reliable, easily applicable and economically viable technical solution. These advantages can be achieved only when the professional equipment is used.
