Abstract
PURPOSE: To simplify operation and greatly reduce the number of working procedures by driving pickets having projection orifices in the ends into the soil in the vicinity of the leak locations of the underground conduit, and projecting and forcing cut-off agents through the ends of the pickets. CONSTITUTION: When leaks at X-printed locations of the joining portion 2 of an underground conduit 1 are detected, pickets 3 are driven from the ground to the joining portion 2. Cut-off agents 5 are forced into the pickets 3 in the arrowhead direction from their upper portions through a pressure pump and transportation hoses 4, and projected to the soil 7 in the vicinity of the leak locations of the joining portion 2 through projection orifices 6 and solidified together with the soil. By this way, it is not necessary for workmen to go into and operate in the conduit, or to dig out the leak portion of the conduit and bury it again, therefore it is possible to simplify the operation and greatly reduce the number of working procedures.
