DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention is intended to prevent sewage from flowing into a sewage house basin when repairing the sewage house basin to which household drainage etc. constantly flows in, and to perform the repair etc. efficiently. And a device used for the method.

[0002]

2. Description of the Related Art When a sewage chamber is used for many years, concrete such as acid and alkali contained in the sewage flowing into the sewage erodes concrete, causing holes or cracks in the sewage, and sewage flows out therefrom. And there is a risk of contaminating the surrounding environment. Therefore, it is necessary to inspect and repair the broken state of the sewage hall at regular intervals, but for the repair, the sewage hall must be emptied. If it is an individual house sewage house measure, it is possible to control so that household wastewater does not flow out, and it is possible to inspect or repair the sewage house measure in the meantime. It is almost impossible to completely prevent such inflows and empty the sewage pits, and it was not possible to carry out inspection and repair of sewage pits effectively. .

[0003]

DISCLOSURE OF THE INVENTION The present invention aims at evacuating a sewage house pit without stopping the flow of sewage in a pipe leading to the sewage house pit, so that repair and the like can be easily performed. It is an object of the present invention to provide a method and an instrument for use therein.

[0004]

According to the present invention, a drum-shaped instrument is attached to a pipe for discharging sewage into a sewage chamber, and the sewage discharged from the pipe is discharged to the outside by the drum-shaped instrument. The above object was achieved by preventing sewage from flowing into the sewage chamber during repairs.

The drum-shaped device used in the present invention comprises a cylindrical portion made of a rubber-elastic film and a disk-shaped portion closing both ends of the cylindrical portion. Attached a small tube so that both ends protruded from the drum-shaped device penetrating the disk-shaped portion, and an air stopper for blowing air into the inside of the drum-shaped device was mounted on at least one of the disk-shaped portions. Things.

[0006] The drum-shaped device is installed and used in a pipe for discharging sewage into a sewage chamber, so that a cylindrical portion thereof is located along the inner circumference of the pipe. Then, air is blown into the inside of the drum-shaped device to inflate the cylindrical portion so that the cylindrical portion is in close contact with the inner periphery of the pipe, so that sewage flowing out of the pipe can only flow through the small pipe of the drum-shaped device. A discharge pipe is attached to the outer end of the small pipe, and sewage can be discharged to the outside from the discharge pipe by a pump.

In the method according to the present invention, the wastewater flowing through the pipe can be discharged to the outside through the small pipe of the drum-shaped appliance. It can be emptied, making its repair very efficient.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. In this example, as shown in A of FIG. 1, sewage 4 such as domestic wastewater flows into a sewage hall 1 through a pipe 2. In the present invention, a drum-shaped device 3 is attached to the pipe 2, and the sewage 4 discharged from the pipe 2 is supplied to the drum-shaped device 3.
Through the small pipe 7 so as to prevent the sewage 4 from flowing into the sewage chamber basin 1.

As shown in FIG. 1B, the drum-shaped instrument 3 has a cylindrical portion 5 (rubber tube) made of a rubber elastic film, and a disk-shaped portion for closing both ends of the cylindrical portion 5. 6 (thick rubber plate), small pipes 7 are attached so that both ends protrude from the drum-shaped instrument 3 through the disk-shaped part 6, and are attached to one of the disk-shaped parts 6. An air tap 8 for blowing air into the drum-shaped instrument 3 is attached.

In this example, the cylindrical portion 5 is replaced by a disc-shaped portion 6
And the inside of the noble drum portion 3 is prevented from leaking out.

The small tube 7 is tightened with screws from both the front and the rear of the rubber disk-shaped portion 6, so that the confidentiality is enhanced due to the rubber characteristics. Further, an adhesive or the like is applied to the portion. And you have more complete confidentiality. In addition,
Similarly, the joint between the air stopper 8 and the disc-shaped portion 6 is formed with good airtightness.

The drum-shaped instrument 3 is installed in the pipe 2 such that the cylindrical portion 5 is located along the inner periphery of the pipe 2, and blows air from an air stopper 8 to inflate the cylindrical portion 5. By doing so, it is fixedly disposed inside the pipe 2 with good adhesion. In this state, a discharge pipe 9 (rubber pipe or the like) is attached to the outer end of the small pipe 7 of the drum-shaped instrument 3, and the wastewater 4 can be discharged from the discharge pipe 9 to the outside by the pump 10 (FIG. 1). A).

Various sewage 4 is discharged from a plurality of pipes 2 into a sewage chamber basin 1. Individual drum-shaped instruments 3 are attached to these pipes 2 and an attachment 11 as shown in FIG.
Is attached to the pump 10, and the sewage flowing out of the plurality of pipes 2 (that is, flowing out of the drum-shaped device 3) is
Through the attachment 11, processing can be performed by one pump 10.

The attachment 11 can be screwed into the water inlet of the pump 10 and is formed by welding a circular iron plate 12 to a cylindrical water inlet attachment. A plurality of screw type sockets 13 are welded. Also, in this socket 13,
A bamboo shoot type joint 14 is screwed in, and the discharge pipe 9 is attached to the joint 14 for use. The unused socket 13 can be closed with a female screw. Therefore, the pipe 2 for discharging the sewage 4 is
And the discharge pipe 9 for guiding the sewage 4 from the pipe 2 to the pump 10
Of the attachment 11 according to the diameter of the
Can be selected and used.

When such an attachment 11 is applied,
Since the sewage 4 flowing out from the plurality of pipes 2 can be efficiently discharged to the outside by one pump 10, the operability is extremely improved.

The attachment 11 may be formed so as to be connected to a pump with a suction hose 15 as shown in FIG.

[0017]

According to the present invention, by installing the drum-shaped appliance 3 inside the pipe 2 for allowing the sewage 4 such as domestic wastewater to flow into the sewage chamber tub 1, the sewage 4 is passed through the small pipe 7 of the drum-shaped appliance 3. By pumping up, the water can be discharged to the outside, so that the sewage pit 1 can be emptied without stopping the drainage of domestic drainage and the like, and repair and the like can be performed with good workability. Thus, the method of the present invention
Conventionally, since it was not possible to completely prevent the inflow of sewage, it can be applied very effectively to repairing the sewage chamber yard 1 of an apartment house, which has been difficult to repair. In addition, the drum-shaped instrument 3 of the present invention is easy to handle because the cylindrical portion 5 can be inflated by air blowing and brought into close contact with the inner surface of the pipe 2. Furthermore, since the sewage 4 can be discharged to the outside by the small pipe 7, the sewage 4 can be easily discharged to the outside by the general-purpose discharge pipe 9 and the pump 10 by forming the small pipe 7 to an appropriate diameter. Becomes The diameter of the cylindrical portion 5 of the drum-shaped instrument 3 can also be set arbitrarily, and can be applied to any pipe 2.
