ABSTRACT:
The invention relates to a method of laying underground conduits along a trench dug into the ground and filled with sludge designed to prevent the trench walls from collapsing.
The trench is at least partly lined with hardenable grout and the conduit laying operations are carried out under the protection of this grout so that, after the same has hardened, it seals the conduit into the ground.
