Abstract

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. The present invention relates to a method of laying pipes and backfilling trench by one or more flows of a thixotropic material comprising successive operations; following: a) construction of a trench at a width l and at a depth P and assembly of pipe elements together at the bottom of the trench; b) implementation position and altimetric adjustment of stops capable of controlling displacement of the assembled pipe elements: c) backfilling of said trench at a height H with a thixotropic material in the state of soil, so as to raise the pipe elements under the effect of the Archimedes thrust; d) removal of the stops when the material thixotropic is in the gel state, the pipe elements remaining stationary; e) possible additional backfilling of the trench.
