摘要： PURPOSE:To unman the operation in a sewer pipe and to enhance safety by providing the front ends of opening/closing legs disposed in a front part body and rear part body with rubber wheels rollable on the inside wall of the pipe. CONSTITUTION:The front part body 1 and the rear part body 2 are hung down from a manhole without bending and are carried into the pipe by bending the front part body 1 and the rear part body 2 with each other. Next, a leg opening air cylinder 39 is actuated and then, links 34, 35 are opened by a link 312 and the rubber wheel 38 is rolled on the peripheral wall of the pipe as the links are opened. The rubber wheel is thus braced and held in contact with the pipe wall. Only the rubber wheel 38 of the front part body 1 is subjected to leg closing and an extension and contraction cylinder 41 is extended to project the front part body 1 forward if the water level in the sewer pipe 103 is low. After the rubber wheel 38 of the front part body 1 is subjected leg opening, the rubber wheel 38 of the rear part body 2 is subjected to leg closing and the extension and contraction cylinder 41 is closed to withdraw the rear part body 2. The rubber wheel 38 of the rear part body 2 is subjected to leg opening to hold the entire part on the pipe wall. The in-pipe moving body is moved forward by inches in such a manner.

摘要： PURPOSE:To withstand the impact when the pig is launched from a pig transmitting and receiving part (launcher) and to ensure the arrival of the pig at a pig transmitting and receiving part (catcher) by providing the outer peripheral surfaces and end faces at both ends in a longitudinal direction with coating layers consisting of epoxy resins. CONSTITUTION:The outer peripheral surfaces and ends at both ends in the longitudinal direction of the pig 1 are provided with the coating layers consisting of the epoxy resins. The width of the epoxy resin coating layers 2 with respect to the longitudinal direction of the pig 1 is not particularly limited and is preferably about 3 to 5mm from the front ends at both ends in the case of the pig 1 of, for example, about 50 to 150mm diameter and about 100 to 250mm length. A sufficient reinforcing effect is not obtainable if the width is
