低下を図ることができる。That is, the embodiment of the drain pipe rehabilitation method according to the present invention provides a method for rehabilitating an existing drain pipe apparatus.
An existing pipe joint 61 (shown by a two-dot chain line in FIG. 2) fixed to the floor slab 2 is cut in the vicinity of the upper and lower surfaces of the floor slab 2 (see a part shown by a one-dot chain line C in FIG. 10). The upper and lower portions of the pipe and the existing vertical drain main pipe are removed, and the straight pipe portion of the existing pipe joint left after cutting is defined as an outer pipe 5.
And a renewal vertical drain main pipe 1 is connected to the renewal pipe joint 6. According to the embodiment of the rehabilitation method of the present invention, the mortar 4 is not required to be frayed at all, and the renewed pipe joint is inserted into the straight pipe portion of the existing pipe joint 61 already centered, that is, the outer pipe 5. Updating vertical drain main pipe, drain collecting pipe, etc. can be immediately installed on this,
It is possible to carry out construction in a short period of time. Moreover, the outer tube 5
As mentioned above, since it was centered in the initial construction,
No centering work is required for rehabilitation, no skill is required,
Safe rehabilitation work without vibration and noise can be performed, and the cost can be significantly reduced.

周まわりを締め付けるようになっている。In this embodiment of the rehabilitation method, since the outer diameter of the renewal pipe joint 6 is slightly smaller than the inner diameter of the existing pipe joint 61, the cross-sectional area of the drainage flow is slightly reduced. By using a material having high corrosion resistance such as stainless steel, the wall thickness of the straight pipe portion of the renewal pipe joint 6 can be reduced, and the decrease rate of the drainage cross-sectional area can be reduced. Further, as a material of the renewal pipe joint 6, a corrosion-resistant material such as a synthetic resin other than stainless steel can be adopted. FIG. 4 shows another receiving structure of the pipe joint 6, wherein the receiving port 7 is provided with a tapered portion 7a which expands in a trumpet shape, and the sealing member 13 has an enlarged diameter portion 14 which comes into contact with the inner surface of the tapered portion 7a.
Is provided, and the circumference of the tapered portion 7a is tightened by a ring-shaped tightening band 16 having a diameter-reducing tightening portion 15 at one location in the circumferential direction.

る。By adopting such a receiving structure, the tightening state around the outer periphery of the receiving port 7 can be made uniform to enhance the sealing performance. FIG. 7 shows another example of the connection structure between the pipe joint 6 and the vertical drain pipe 1. The vertical drain pipe 1 is a straight pipe having no receiving port at the upper end, and the spigot 9 of the pipe joint 6 and the vertical drain pipe 1 are connected. The upper end is abutted with a sealing material 17 therebetween, and is fastened and fixed by a radially expandable and contractible band-like joint 18 composed of a C-shaped ring shown in FIGS. This band-shaped joint 18
Is a method in which a rubber-made cylindrical sealing material 19 is surrounded by a C-shaped split plate 20, and a bolt 2 is attached to a tightening flange 21 projecting substantially radially outward from both ends of the split plate 20.
2, the split plate 20 is configured to be able to expand or contract in the radial direction by tightening and loosening the bolt 22. Therefore, the joint 18 is previously fitted to the upper end of the vertical drain main body 1 at a position shown by a two-dot chain line in FIG. Pushing up the joint 18 upwards as shown in FIG.
By tightening and fixing the bolts 22 at the positions shown by solid lines in FIG.

ばよい。As described above, the drainage pipe device according to the present invention is a drainage pipe device in which a vertical drainage main pipe is connected via a pipe joint penetratingly mounted on a floor slab. Since the existing drainage pipe system is configured to be penetrated inside the outer pipe fixed to the floor slab in a penetrating manner, if the existing drainage pipe device needs to be rehabilitated due to aging, the pipe joint and the vertical drainage main pipe or vertical drainage main pipe are required. After separating the connection with the collecting pipe and the like, and removing the old existing fitting from the outer pipe, the replacement fitting is installed in the outer pipe, and the updated vertical drain main pipe or the like may be connected to the replacement fitting. .

The drain pipe device according to the present invention cuts the outer pipe near the upper and lower surfaces of the floor slab of the existing pipe joint without need. It is composed of the straight pipe part left as it is. Therefore, even when the existing fitting is not attached to the floor slab via the outer pipe, the existing fitting can be used as the outer pipe at the time of rehabilitation of the existing drainage pipe device,
It is possible to eliminate the breaking work of the floor slab.

ことが可能である。Further, the method for rehabilitating a drainage pipe device according to the present invention is a method for rehabilitating an existing drainage pipe device, wherein an existing pipe joint fixed to a floor slab is located near upper and lower surfaces of the floor slab. To remove the upper and lower parts and the existing vertical drain main pipe, cut the existing pipe joint and leave the straight pipe portion remaining as an outer pipe, insert a renewal pipe joint through the outer pipe, and install the renewal pipe. Since the renewed vertical drain main pipe is connected to the joint, it is not necessary to remove the existing pipe joint by scouring the floor slab, eliminating vibration and noise, and rehabilitating in a short time without much skill, It is possible to significantly reduce costs.
