Description

  The present invention relates to a repair device and a repair method for a drainage facility in which a liner layer for repair is applied to an inner wall of a drain trap or drain pipe corroded or damaged due to aging or the like.

  In recent years, when drainage traps and drainage pipes laid at the bottom of floor slabs are corroded or damaged due to aging, etc., instead of newly replacing drainage traps and drainage pipes, Repair is performed by forming a liner layer inside.

  Therefore, referring to Patent Document 1 regarding the conventional repair method, “the drain pipe, the drain pipe production method and the reinforcing member” described in this document is a liner layer in the pipe with a cloth material impregnated with a curable resin. Is pasted as. However, this repair method can be repaired when the drain pipe has a shape extending vertically downward from the drain trap. However, when the drain pipe has a bent portion below the drain pipe, the bent pipe is inserted into the pipe in the lateral direction. It is impossible to apply a liner layer.

  By the way, this kind of drainage equipment is inwardly connected to the outer cylinder part of the drain trap in order to prevent water from entering the floor member in case a crack or the like occurs in the floor member around the drain trap. A through hole is formed.

  However, in the invention of Patent Document 1, the reinforcing member is integrated with the inner peripheral surface of the outer cylindrical portion in the drain trap, the outer peripheral surface and the inner peripheral surface of the inner cylindrical portion, and the inner peripheral surface of the drain pipe connected to the inner cylindrical portion. It is set as the structure which press-contacts so that it may cover. For this reason, in the reinforcement member of patent document 1, as mentioned above, the through-hole formed in the outer cylinder part is block | closed, and the problem that the function of a through-hole will be impaired arises.

  By the way, in general households and apartment houses, a bent pipe is often laid in the horizontal direction under the floor from a drain pipe of a bathroom, etc., or a connection portion between the bent pipe and a straight pipe below the drain trap, or It is recognized that the connection portion between the bent pipe and the horizontal pipe provided in the horizontal direction under the floor is the place where water leakage is most likely to occur.

  In addition, the drain trap structure that is actually constructed has a double structure in which the outer cylinder is separated in the event that a crack or the like occurs in the floor member, and there is a circumferential gap between these double structures. By forming (refer to FIG. 8 and FIG. 12), moisture that has entered from the floor member is guided to the inside of the drain trap.

  Therefore, when the drain trap and drain pipe having such a structure are repaired by the liner layer for repair, not only the liner layer for repair can be formed on the inner wall of the drain pipe having the bent portion, but also as described above. It is necessary to make a repair method that does not block the circumferential gap formed in the outer peripheral wall of the drain trap.

Further, in this embodiment, as shown in FIGS. 9A and 9B, a configuration is formed in which an extra length portion 28 c is formed by folding the lower portion of the lower silicon rubber 28 b of the lining presser 24 around the outer periphery of the lower end of the tube body 25. It is said. The extra length portion 28c of the lower silicon rubber 28b expands as shown in FIG. 9B by injecting compressed air into the lower silicon rubber 28b.

  Furthermore, in this embodiment, as shown in FIGS. 9A to 9C, a rotatable lever 40 is provided on the upper portion of the sealing member 26 provided at the upper end of the lining presser 24. A tube member 41 is provided which is downward and protrudes downward from the lower end of the tube body 25 of the lining presser 24. At the lower end of the tube member 41, a rod member 41a in the tube member 41 is interlocked with the turning operation of the lever 40. It is set as the structure which provided the rubber member 42 which bulged outward by moving up and down.

  Hereinafter, as shown in FIG. 12, using the lining presser 24, the drain trap is opened without closing the circumferential gap 4c between the upper outer cylinder part 4a and the lower outer cylinder part 4b. A repair method for forming a liner layer on the inner wall 4 will be described.

  First, as shown in FIGS. 10B and 10C, a cylindrical upper lining formed by impregnating a lining agent in a state where the outer periphery of the upper silicon rubber 28a and the lower silicon rubber 28b of the lining presser 24 is separated. The cloth 29a and the lower lining cloth 29b are covered with each other, and the folded portion 29d of the lower lining cloth 29b is formed by folding the excess length formed below the lower lining cloth 29b inward of the folded portion 28c of the lower silicone rubber 28b. To do.

  As shown in FIG. 10 (a), the upper lining cloth 29a and the lower lining cloth 29b need to be sufficiently impregnated with the lining agent 17 by thoroughly squeezing the lining agent 17 in a state in which the lining agent 17 has been infiltrated. There is. As the lining agent 17, a curable resin such as an epoxy resin may be used as in the first embodiment.

  Then, as shown in FIG. 11A, the inner periphery of the pipe body 25 of the lining presser 24 is fitted into the outer periphery of the inner cylinder portion 11. Further, when the rubber member 42 suspended from the lining presser 24 is inserted into the straight pipe 20 through the inner cylinder portion 11 of the drain trap 4, as shown in FIG. When the rubber member 42 located in the straight pipe 20 swells, the inner wall of the straight pipe 20 is pressed, and the lining presser 24 is fixed. As a result, as described later, it is possible to prevent the lining presser 24 from being lifted upward as a reaction when compressed air is injected into the upper silicon rubber 28a and the lower silicon rubber 28b.

  Next, as shown in FIG. 11 (b), when compressed air is injected through the injection hoses 30 a and 31 a of the lining presser 24, the upper silicone rubber 28 a and the lower silicone rubber 28 b expand inside and outside the tube body 25. .

It can be pressed and attached to the surface.

  Further, when the lower silicone rubber 28b expands as described above, the folded portion 28c that turns back the extra length formed below the lower silicone rubber 28b is formed at the bottom of the lower outer cylinder portion 4b of the drain trap 4. By inflating and adhering toward the corner portion 23 of the corner portion with the bottom portion 14, it becomes possible to form a liner layer without creating an air reservoir in the corner portion 23.

  Next, after confirming that the lining agent of the upper lining cloth 29a and the lower lining cloth 29b has hardened after a predetermined time, the air vent cocks 32a and 32b are opened to compress the upper lining cloth 29a and the lower lining cloth 29b. Remove air and reduce. Further, by returning the lever 40 to the original position, the rubber member 42 is reduced and the pressing force on the straight pipe 20 is released, and then the lining presser 24 is pulled out upward.

  By such a repair method of this embodiment, as shown in FIG. 12, the upper lining cloth 29a is attached to the inner peripheral surface of the upper outer cylinder part 4a and the lower lining cloth 29b is attached to the outer part of the lower part as shown in FIG. It adheres in the state isolate | separated to the internal peripheral surface of the cylinder part 4b. At this time, the folded portion 29 d of the lower lining cloth 29 b is attached as the rising portion 34 on the outer periphery of the inner cylinder portion 11. In the present embodiment, the liner layer is formed on the inner wall of the drain trap 4 in such a state that the circumferential gap 4c between the upper outer cylinder portion 4a and the lower outer cylinder portion 4b is opened without being blocked by such a repair method. It becomes possible to form.

  The drainage equipment repairing apparatus and repair method according to the present invention is a repair work in which a liner layer for repairing is provided on the inner wall of a drainage pipe even in the case of having a bent part of the drainage pipe directly under the drainage trap in a general household or an apartment house.
