Abstract (en)

[origin: FR2758378A1] The invention concerns a pipe fitting and trench filling method by means of one or several underpours of a thixotropic material comprising the following successive steps: a) digging a trench or length l and depth P and assembling together pipe elements at the bottom of the trench; b) setting and altimetric adjusting of stops for controlling the displacement of the assembled pipe elements; c) filling up said trench to a height H with a material thixotropic to the state of the soil so as to bring the pipes up by the effect of buoyancy; d) removing the stops when the thixotrope material has gelled, the pipe elements remaining fixed; e) optional complementary filling up of the trench.
