Document Type and Number:
Japanese Patent JP7244825
Kind Code:
B2
Abstract:
To provide a construction method of a filler between an inner tube and an outer tube of an underground buried pipe structure comprising a double tube of the inner tube and the outer tube with a cable being passed through inside of the inner tube, without cutting open the underground buried pipe structure largely, causing neither damage nor deterioration in performance of the cable in the inner tube when the filler is filled between the inner tube and the outer tube, and where there is no possibility that filling effect becomes insufficient due to poor filling in the presence of stagnant water.SOLUTION: A construction method of a filler is provided between an inner tube and an outer tube of an underground buried pipe structure composed of a double tube of a plurality of inner tubes and one outer tube with a cable being passed through inside of the inner tube. A low heat generation type under water non-separable filler is used having a density of 1.36-1.70 kg/L.SELECTED DRAWING: Figure 2
