摘要： PROBLEM TO BE SOLVED: To quickly repair an existing pipe of an existing manhole into a new pipe and to exhibit sufficient watertightness between the new pipe and the existing manhole. SOLUTION: This method is to repair the existing pipe connected to a bore in a wall surface 1a of the existing manhole 1 with rigid adhesive into the new pipe 2. In this method, the existing pipe and a part of the rigid adhesive are removed from the existing manhole 1 so as to form a new bore 3 and a concrete block 4 is watertightly fixed to the circumference 1b of the new bore 3 by adhesive 5. The concrete block 4 has an insertion hole 4a for inserting the new pipe 2, the new pipe 2 is inserted into the insertion hole 4a and the new bore 3, and a flexible joint 6 is disposed between the new pipe 2 and the insertion hole 3. The flexible joint 6 is provided with a cylinder portion 6a to be press-fitted into the insertion hole 4a, a covering portion 6b covering the new pipe 2, and a connecting portion 6c connecting between the cylinder portion 6a and the covering portion 6b. The flexible joint 6 cuts off the interval between the new pipe 2 and the insertion hole 4a and the rigid adhesive 7 fills the interval between the new pipe 2 and the new bore 3.

摘要： PROBLEM TO BE SOLVED: To give flexibility corresponding to relative position change between a manhole and a ribbed pipe and ensure water stop by connecting the manhole and the ribbed pipe via a flexible joint. SOLUTION: A drilled hole 20 is provided to allow connection between a manhole 3 and a pipe 1 provided with a rib 2 on the outer periphery via an elastic flexible joint 16A. The end of the pipe 1 is inserted in the drilled hole 20. The flexible joint has a fixing part 5 mounted in the manhole, a cylindrical part 6 in which the pipe is inserted and a connection part 18 for connecting the fixing part and the cylindrical part. A connection structure includes a water stop material layer 8 provided between the inner periphery of the cylindrical part and the outer periphery of the pipe and a fastening member 7 mounted on the outer periphery of the cylindrical part. The fastening member is used to fasten the cylindrical part and the water stop material layer and thus thrust the water stop material layer against the rib on the outer periphery of the pipe, causing water stop between the cylindrical part and the outer periphery of the pipe.

摘要： PROBLEM TO BE SOLVED: To improve the water stop property by stopping a high water pressure part such as a position between the side wall and the bottom slab of a large scale and extremely deep underground tank with a rubber water stop plate provided with a reinforcing cloth at the surface of the body. SOLUTION: The body is formed of plate-form parts 2a, 2b, anchorage rib parts 3a, 3b, and a semicircular valve 5. A butyl rubber sheet 7 with reinforced cloth is stuck on the surface of the ribs 3a, 3b and the valve 5 to form a rubber water stop plate 1 having a slant section and arrange it in the peripheral direction between the bottom plate 111 and the side wall 109 of the underground tank. Underground water flows in the clearance 11 between the side wall 109 and the bottom plate 111 and the water pressure acts on the stop plate 1 and ribs 3a, 3b are pushed on the side wall 109 and the bottom plate 111 respectively and the sheet 7 is held between the ribs 3a, 3b and the side wall 109 and the bottom plate 111 and anchored therein. The anchoring force increases proportionally to the water pressure as the depth increases. The sheet 7 of which both ends are anchored by the ribs 3a, 3b prevents deformation of the water stop plate 1 resulting from the water pressure. In this way, an absorbing performance of deformation can be increased and the stop plate can cope with a high water pressure.

摘要： PROBLEM TO BE SOLVED: To provide a rubber composition which has excellent adhesion to concrete and can be used for producing a water cut off material which does not need a releasing film attached on its surface, by incorporating calcium oxide into a solid rubber material in a specific amount. SOLUTION: This composition comprises 100 pts.wt. of a solid rubber material and 2 to 300 pts.wt. of calcium oxide, and optionally, further comprises 5 to 50 pts.wt. of a hydrophilic polymer. Solid rubber materials include synthetic rubber, natural rubber and reclaimed rubber. Among various types of reclaimed rubber, the one derived from a tube which is composed mainly of butyl rubber is suitable for this composition. As calcium oxide, quick lime or calcined lime is used and the one surface-treated with a fatty acid, a surfactant or the like is more suitable. Hydrophilic polymers include ethylene glycols, such as a polyethylene glycol, an ethylene oxide resin and the like, urethane prepolymers, butyral resins, poly(vinyl alcohol)s and the like.
