Water stop structure and pipe installation structure of multiple water supply pipes

摘要

PROBLEM TO BE SOLVED: To provide a water stop structure and a pipe installation structure of a multiple water supply pipe capable of preventing water leakage in a water supply pipe and a multiple water supply pipe having an outer pipe covering the water supply pipe. SOLUTION: A water stop structure 1 of a multiple water supply pipe is a water stop structure for a multiple water supply pipe 2 having a water supply pipe 21 and an outer pipe 22 covering the water supply pipe 21. The water stop structure 1 includes a heat-shrinkable tube 3 in a contracted state that extends from the outer peripheral surface of the water supply pipe 21 to the outer peripheral surface of the outer pipe 22 and covers the boundary between the water supply pipe 21 and the outer pipe 22. ..
