IPC: E04B1/66
Filed: 1994-11-02
Abstract: PURPOSE: To prevent the generation of a backflow to a hose of a water stop material and execute work more definitely with higher efficiency by injecting a compressed air into a water stop material injection hose buried along a construction joint after suction washing and thereby inspecting a construction failure. CONSTITUTION: A water stop material, such as epoxy resin, cement-based slurry is infected into a clearance of a construction joint 21 from a water stop hose 1 buried in the construction joint 21 of concrete, thereby sealing water. After the infection is over, the water stop material in the water stop hose 1 is absorbed and washed while a compressed air equivalent to the pressure remaining in the concrete is injected into the hose 1, thereby holding the water stop material until it is cured. In this case, when the pressure in the hose 1 dropped dramatically, it is assumed that there exists a clearance in the concrete so that it is necessary to infect the water stop material once again. Or a recessed part 7 is installed to the construction joint 2 and a connection hose 6 is housed so that it may be convenient if reinjection is required after an elapsed time.  This construction makes it possible to eliminate a construction failure and produce the effect of water stop definitely and enhance workability as well.
