CA 2278224

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.

La présente invention concerne un procédé de pose de tuyaux et le remblaiement de tranchée par une ou plusieurs coulées d'un matériau thixotrope comprenant les opérations successives; suivantes: a) réalisation d'une tranchée à une largeur l et à une profondeur P et assemblage entre eux des éléments de tuyaux au fond de la tranchée; b) mise en place et réglage altimétrique de butées aptes à contrôler le déplacement des éléments de tuyaux assemblés: c) remblaiement de ladite tranchée à une hauteur H avec un matériau thixotrope à l'état de sol, de façon à faire remonter les éléments de tuyaux sous l'effet de la poussée d'Archimède; d) retrait des butées lorsque le matériau thixotrope est à l'état de gel, les éléments de tuyaux restant immobiles; e) éventuel remblaiement complémentaire de la tranchée.
