摘要： PROBLEM TO BE SOLVED: To provide sufficient sealing performance properties, by forming on the end side of an acceptor, a first slant surface inclined at a first angle against a pipe shaft, and forming on the inner end side of the acceptor from the first slant surface, a second slant surface inclined at a second larger than the first angle against the pipe shaft. SOLUTION: On the slant surface of a lip 28, a first slant surface 30 inclined at a first angle against a pipe shaft is formed on the end side of an acceptor 14, a second slant surface 32 which is extended from the end part of the first slant surface 30 and inclined at a second angle larger than the first angle, is formed, and a thin part 34 is formed in a part of the inner end side end part of the acceptor 14 as the free end of the lip 28. Also, a projected part 36 is formed on the inner end side of the acceptor 14 in a main body 22 by being projected in a pipe shaft direction. Hereby, sufficient sealing performance can be obtained, and besides, the twisting of a rubber ring 10 can be prevented.

摘要： PROBLEM TO BE SOLVED: To increase the withstand load against the collapse of a branch pipe while keeping the earthquake resistance. SOLUTION: When a branch pipe 16 is relatively displaced relative to a main pipe 12 for sewage when the ground is displaced due to an earthquake, or the like, the distortion of the pipe line at a branched part can be absorbed by the bending of a joint part 22 made of the flexible material. Even when the excessive force is applied to a ring 20 from the branch pipe 16 when the main pipe 12 for sewage is buried deep, the ring 20 is not deformed because the ring is formed of the hard material.

摘要： PROBLEM TO BE SOLVED: To improve the stability of a rubber ring without reducing its strength. SOLUTION: A corner part 14b in the deep side of a rubber ring groove 14 is formed on a radius surface A having a radius (h) within the range of 90 deg.. When a rubber ring is joined by inserting a vinyl chloride pipe into a rubber ring socket 10, the force of the vinyl chloride pipe for pushing a rubber ring 12 into a deep side is applied to the radius surface A of the rubber ring groove 14 and thereby the rubber ring 12 is locked in the rubber ring groove 14. Thus, the falling of the rubber ring 12 from the rubber ring groove 14 to the deep side is prevented and since the rubber ring groove 14 is not formed by expanding a compressed diameter metallic mole, the number of thin parts in the periphery of the rubber ring socket 10 is small. Thus, without reducing a strength, the stability of the rubber ring is improved.

摘要： PURPOSE: To improve execution workability by forming a flexing deformation part, flexed in a width direction between two engaging parts, so as to protrude in the same direction to the protruding direction of a protrusive streak. CONSTITUTION: In a joiner 10 for connecting the fellow winding side edges of a strip 14 helically wound along an internal surface of a pipe 12, the joiner comprises two engaging parts 30 formed with a protrusive streak 22 fitted to each other in the winding side edge in the respective one main surface and a flexing deformation part 34 formed so as to protrude in the same direction to the protruding direction of the protrusive streak 22 between the two engaging parts 30 further to flex in a width direction. Thus by forming the flexing deformation part 34 flexed in a width direction between the two engaging parts 30 so as to protrude in the same direction to the protruding direction of the protrusive streak 22, sufficient strength can be ensured against a charging pressure of back filling material, and also a sufficient extending/contracting amount can be ensured. In this way, execution workability can be improved.

摘要： PROBLEM TO BE SOLVED: To prevent a joiner from separating from a strip. SOLUTION: A strip 14 wrapped round spirally along the inner surface of a sewer pipe is joined by a joiner 10 in its width direction side peripheries, and a lining material 42 is filled between the inner surface of the sewer pipe 12, the strip 14, and the joiner 10. In this way, an anchor part 40 formed in the joiner 10 is buried in the lining material 42, so that after curing of the lining material 42, the anchor 40 is fastened firmly in the lining material 42.

摘要： PROBLEM TO BE SOLVED: To prevent water leakage from a mounting part of a manhole joint. SOLUTION: When a projection 28 of a rubber joint 20 is fitted in a hole 46 of a vinyl chloride flange 40, the rubber joint 20 and the vinyl chloride flange 40 are integrated. A flange 26 of the rubber joint 20 is pressed against a side wall 12 of a manhole by a pressing plate part 44, adheres on it and is bonded on it. Moreover, when a band 50 is mounted in a groove 30 of a cylindrical part 22 of the rubber joint 20 and is tightened, a projection bar formed on inner periphery of the cylindrical part 22 is pressed against outer periphery of a vinyl chloride pipe 16, adheres, and is fixed on it. If force which bends the vinyl chloride pipe 16 is applied thereon due to earthquake, the force is absorbed by the deformation of a bent part 24 of the rubber joint 20. At this time, the flange 26 of the rubber joint 20 and the cylindrical part 22 adhere on outer periphery of the side wall 12 of the manhole and the vinyl chloride pipe 16 closely and are held there.

摘要： PURPOSE:To obtain a three-dimentional and miniature manhole by providing openings separately from each other on upper and lower sides on the side surfaces of a manhole body, and connecting storm sewer pipes to the upper side openings and sanitary sewer pipes to the lower side openings. CONSTITUTION:First openings 22a, 22b and second openings 30a, 30b are provided on the side surfaces of a manhole 14 having an opening 12 on the top face. A hatch 28 is provided between the first openings and the second openings. Further, sanitary sewer pipes 24a, 24b are connected to the first openings 22a, 22b,while storm sewer pipes 32a, 32b are connected to the second openings 30a, 30b respectively. When checks, etc., are made, the storm sewer and sanitary sewer can be checked out at one time. Thus, a manhole capable of being installed even under a narrow road can be obtained.
