摘要： PROBLEM TO BE SOLVED: To obtain waterproofing performance equal or superior to that of stretching a waterproofing sheet only by spraying resin by forming a water permeable layer made by foaming resin and an impermeable layer made by non-foaming resin. SOLUTION: After an antifoamer and a foam breaker such as grease or the like is applied to the surface of a primary concrete layer 1 formed by spraying concrete to the natural ground 100, foaming resin is sprayed and foamed to form a water permeable layer 2. The water permeable layer 2 uses urethane resin where 5-30% evanescent particles such as salt, hydroxide, water soluble matter, sublimated matter and so on are mixed, and after foaming, through holes are formed in a skin layer of the interface with the primary concrete layer 1. Further, low-foaming or non-foaming urethane resin is sprayed to the surface of the water permeable layer 2 to construct a water impermeable layer 3 and a lining concrete layer 4 is constructed on the whole surface of the water impermeable layer 3. Water leaking from the natural ground 100 side permeates from the through holes of the skin layer into the water permeable layer 2 to be moved downward in the water permeable layer 2 and discharged.

摘要： PURPOSE:To enable the easy repair of an existing pipe in a sewer of sewerage or the like without performing an excavation work. CONSTITUTION:A repair member consists of a tubular part 10 locked on the inner peripheral surface of an existing pipe 101 and a flange part 11 formed on one end of the tubular part 10 to be locked on the end face of the existing pipe 101. At least the flange part 11 is formed of shape memory effect resin to store the shape of the flange part 11, and a repair member 1 deformed to be inserted into the existing pipe 101 is inserted in the existing pipe 101 so that the shape of the flange part 11 is restored to engage one end face of the existing pipe 101. The repair member 1 is inserted from the other end face of the existing pipe 101 so that the end face of the existing pipe 101 joined with a main pipe 100 can be repaired only by restoring the shape of the flange part 11.

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 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.
