摘要： PROBLEM TO BE SOLVED: To eliminate a load and a risk on a worker by eliminating an operation for removing an invert at the bottom of a manhole and reduce construction time and cost, in an aseismic construction method in which a gap is formed in a manhole side-wall around a sewage pipe for providing earthquake resistance to the connected portion of the manhole and the sewage pipe and a damping material is filled in the gap.
SOLUTION: This construction method includes a first step of forming, in the manhole side-wall, a groove 34 which is recessed a predetermined depth into the manhole side-wall circumferentially in the wall of the sewage pipe from the inside of the end of the sewage pipe, a second step of slitting the sewage pipe by pressing a cutting tool 36 in which a crank pin is used as a shaft-like rotary blade 39 in the radial direction from the inner groove edge of the pipe end while rotating the rotary blade, changing the direction and circumferentially turning around the pipe end after the rotary blade cuts off the pipe end, and cutting the sidewall of the manhole around the pipe end to form an annular gap which is brought into contact with the pipe end around the pipe end, and a third step of filling a rubber or resin damping material into the gap.

摘要： PROBLEM TO BE SOLVED: To provide a pressure releasing device for underground structure capable of releasing pressure with a simple structure.SOLUTION: A pressure releasing device for underground structure is provided with an air-permeable lid body 12 which communicates with a sewer pipeline A and which is supported by the ground surface opening edge part of an underground structure B open to the ground surface, through a lid body support frame 13, and a pressure adjusting unit 20 which is arranged under the air-permeable lid body 12 and which divides the inside of the underground structure B into the air-permeable lid body side and the sewer pipeline side. The pressure adjusting unit 20 has a check valve for operating in the opening direction by the rise in the pressure on the sewer pipeline side in the underground structure so as to open the pressure on the sewer pipeline side to the air-permeable lid body side. The pressure adjusting unit 20 is provided with a fixing overhang part 21 held between the lid body support frame 13 and the air-permeable lid body 12 and a swollen part 23 in a form of projecting downward supported by the fixing overhang part 21, and the check valve 34 is disposed in the swollen part 23.
