Title
(EN) METHOD FOR FILLING A TRENCH COMPRISING A PAIR OF CONDUITS AND SUCH A FILLED TRENCH
(FR) PROCÉDÉ DE REMBLAYAGE DE TRANCHÉE COMPORTANT DEUX CONDUITES ET TRANCHÉE AINSI REMBLAYÉE
Abstract
(EN)
A filled trench is disclosed. The filled trench comprises: a pair of conduits (3a, 3b) for delivering fluid with a different temperature in each of the conduits, the pair of conduits being surrounded by filling material; a first section (5a) filled with a filling material of a first type (4a), wherein the first filled section (5a) of the filled trench occupies a space surrounding a first conduit (3a) of the pair of conduits; and a second section (5b) filled with a filling material of a second type (4b), wherein the second filled section (5b) of the filled trench occupies a space surrounding a second conduit (3b) of the pair of conduits. The filling material of the first type (4a) has a first thermal conduction coefficient and the filling material of the second type (4b) has a second thermal conduction coefficient, the second thermal conduction coefficient being different from the first thermal conduction coefficient.

L'invention concerne une tranchée remblayée. La tranchée remblayée comporte : deux conduites (3a, 3b) destinées à acheminer un liquide à une température différente dans chaque conduite (3a, 3b), les deux conduites (3a, 3b) étant entourées d'un matériau de remblai; une première section (5a) remplie d'un matériau de remblai d'un premier type (4a), la première section remblayée (5a) de la tranchée remblayée occupant un espace entourant une première conduite (3a) de la paire de conduites: et une seconde section (5b) remblayée d'un matériau de remblai d'un second type (4b), la seconde section remblayée (5b) de la tranchée remblayée occupant un espace entourant une seconde conduite (3b) de la paire de conduites. Le matériau de remblai du premier type (4a) possède un premier coefficient de conduction thermique et le matériau de remblai du second type (4b) possède un second coefficient de conduction thermique, le second coefficient de conduction thermique étant différent du premier coefficient de conduction thermique.
