摘要： PURPOSE: To provide a manhole repairing method, by which a lining layer, the inner surface of which is smooth, can be simply obtained. CONSTITUTION: Manhole repairing materials 1, 3 for covering the straight wall part of the manhole inner wall surface A and a manhole repairing material 9 for covering the inclined wall part are prepared, and sequentially inserted in the manhole to be fitted and stacked after the sewer pipe port E part is closed by a closing material 45. The manhole repairing materials 1, 3, 9 are increased in diameter to cover the manhole inner wall surface A with a gap 89, and then the gap 89 is filled with a hardening filler 115 for a lining.

摘要： PURPOSE: To simply form a lining layer which has sufficient repair effect and a smooth inner face. CONSTITUTION: The cylindrical part 3 of a manhole repair material is inserted into a manhole 29 in the state of a contracted diameter, and then, an adhesive layer 11 is pressed against an inner wall face 33 for sticking the cylindrical part 3. Next, the truncated conical part 5 of the manhole repair material is inserted into the manhole 29 in the state of the contracted diameter, and then an adhesive layer 13 is pressed against the inner wall face 33 for sticking the truncated conical part 5 in a state where it mounts on the cylindrical part 3.

摘要： PURPOSE:To form a lining layer having sufficient repairing effect and having a smooth inside within a short period of time. CONSTITUTION:A cylindrical section 3 of a manhole repairing material is so constructed that an interior wall surface 19 and a space 37 are provided inside a manhole 15. The space 37 is filled with lining ordinary temperature hardening epoxy resin 43. After the lining ordinary temperature hardening epoxy resin 43 is solidified, a cut head conical section 5 is so mounted to the upper end of a cylindrical section 3 that it is provided with an interior wall surface 19 and a space 49. The space 49 is filled with the lining ordinary temperature hardening epoxy resin 51 to leave it alone until the epoxy resin is solidified.

摘要： PURPOSE:To provide a construction where a vent hole is quickly closed under the rainy weather for preventing the ingress of rain drops, and opened for releasing gas from a manhole quickly after the rain stops, regarding an approximately plate type manhole cover having vent holes drilled in a thicknesswise direction. CONSTITUTION:This cover is formed out of a cover body 1 and a resin member 2, and each of vent holes 20 is fitted with a foamed resin member 2 capable of reversibly absorbing and releasing water and having a continuous cell at least partly. In this case, the member 2 has a large surface area. Thus, the member 2 quickly absorbs water and expands, thereby closing the vent holes 20. Also, the member 2 quickly releases water, thereby opening the vent holes 20.

摘要： PURPOSE:To provide a construction where a vent hole is closed under the rainy weather for preventing the ingress of rain drops, and opened for releasing gas from a manhole after the rain stops, regarding an approximately plate type manhole cover having vent holes drilled in a thicknesswise direction. CONSTITUTION:This manhole cover has a frame type case 3 laid at a position faced to the opening of a vent hole 10 or therein, and having a lattice 35, and a resin member 4 laid in the case 3 and capable of absorbing and releasing water reversibly. Under the rainy weather or the like, the vent hole 10 is closed because of the swelling of the member 4 due to water absorption. In a dry condition, the member 4 shrinks to open the vent hole 10, and sand or the like drops from the lattice 35. Thus, gas in a manhole can be smoothly discharged.

摘要： PURPOSE:To contrive the reduction of cost facilitating execution while preventing the leakage of water by providing an elastic plateshaped unit to be arranged in a concrete internal wall surface further a securing tool to be driven closely adhering. CONSTITUTION:A waterproof layer 10 of deterioration part of a conduit is removed from inside a stratum 8, and a concrete layer 9 is exposed. Next matching with a circumferential length of the internal peripheral surface of the concrete layer 9, a polyvinyl chloride-made elastic plate 10a is cut, rounded, curved so as to be along the internal peripheral surface and internally fitted into the concrete layer 9. And next utilizing repulsive elasticity of the plate 10a, it is closely attached to the internal peripheral surface of the concrete layer 9. A nail 14 is driven by a pneumatic nailing gun to one end part side in the upper end of the elastic plate 10a through a rubber packing 12 and a retaining washer 13, and the plate 10a is fixed to an upper end of the concrete layer 9 while thermally fused by a hot metal system adhesive agent.

摘要： PURPOSE:To make a tunnel waterproof by forming a water-proofing layer of a synthetic resin board, synthetic rubber board, metal board and others all having impact resiliency on the surface of an excavated rock, and infiltrating a hardening filler between a bedrock and the water-proofing layer to carry out back-filling. CONSTITUTION:A board with impact resiliency or a synthetic resin board, synthetic rubber board, fiber reinforcing resin board, metal board and others are stuck on the wall of a bedrock of a drift constructed by excavating the ground in a state of watertightness by using a machine and the pressure of a jig. Thus, water-proofing boards 3 are subsequently stuck lengthwise of a tunnel up to an appropriate length in the shape of an arch for placing one time of lining concrete. Concrete, gravel, crushed stone or muck are filled the space between the bedrock 1 and water-proofing boards 3, and cement milk, epoxy resin, urethane resin and the like as an bonding agent is infiltrated later on to carry out back-filling.
