In what type of soils or geological conditions is pipe ramming most suitable?

The pipe ramming is a technique that is particularly suitable for terrain with low surface cohesion, presence of high water table o urban constraints that prevent open excavation.

At Eurohinca, This technology is adapted by means of different excavation systems according to the geology of the environment:

  • At soft or water-saturated soils, is used, the Hydroshield TBM, The pressure is maintained at the front with bentonite sludge, preventing seepage or collapse.

  • At stable or rocky terrain, systems are used to open shield with specific cutting tools (bucket, miner or pickaxe).

  • At urban areas with difficult access or crossings under infrastructures, the microtunneling guarantees millimetric precision and minimum disturbance of the environment.

Pipe ramming allows working under roads, rivers, industrial or coastal areas without interrupting the surface environment, offering a solution safe, clean and sustainable in geotechnical conditions where traditional excavation is not feasible.
