Abstract

PURPOSE: To conduct construction, which lays a main pipe in a sleeve pipe, efficiently and economically by injecting a mixed material, which is separated into a sedimentation layer and a floating layer after a fixed time passes, to a lower surface of the sleeve pipe when laying the main pipe in the sleeve pipe.
CONSTITUTION: Sluice plates 8 are fixed at both pipe ends of a sleeve pipe 2, an injector 9 consisting of each mixer, pump and injecting hole for an A liquid and a B liquid is prepared on the ground, a nose of the injecting hose 9' is pulled into the sleeve pipe 2 and a mixed liquid 10 is injected. When the mixed liquid 10 is injected up to fixed depth, injection is stopped. When a fixed time passes, coagulating components in the mixed liquid 10 settle, lubricating components float, and the liquid is stratified, gels, solidifies and is changed into a supporting layer. A main pipe, to a nose thereof a guiding pipe with a sliding means is fixed, is drawn or inserted into the sleeve pipe, and the main pipe is laid being slide on the supporting layer.
