Direct Pipe

Pipe installation method that combines the operation of microtunneling machines and HDD. This method performs simultaneously the excavation and installation of the pipe, so it does not require the necessary enlargement in HDD or an attack pit with reaction wall, resulting in a fast, versatile, efficient and effective method. It is applicable to any soil condition.

On the other hand, it requires a huge ramp surface, since it requires a long working platform on which the metal pipe is welded.
