The present invention relates to a sealing device for sewage pipes (or water pipes), and more particularly, to a sealing device for sewage pipes for sealing connections between sewage pipes and sewage pipes through which living (or industrial) wastewater (or drinking water) flows.

Generally, sewage, which is a domestic wastewater after being used as domestic water in homes and factories, flows through sewage pipes installed in the basement and is purified and treated in sewage terminal treatment plants.

Recently, in order to protect nature and prevent environmental pollution, and to protect nature, it is necessary to pay close attention not to contaminate groundwater or soil by leaking in the middle before it reaches the sewage treatment plant after draining sewage, which is a domestic wastewater, from general households. have. For example, the domestic wastewater drained from homes, etc., goes through the various stages of collection, sedimentation, and purification before reaching the sewage treatment plant, and then is transferred to the sewage treatment plant, which is the final destination.

The sewer pipe is the pipeline forming this path. This sewer needs to be continuous, so it is buried throughout the process. Therefore, it is necessary to prevent the leakage of sewage in the part where the sewer pipes are connected. It is used for this purpose is a sewer pipe sealing device.

In the conventional sealing apparatus, a tape-type band or the like having waterproofness at a connection portion between the sewer pipe and the sewer pipe is sealed daily by hand. However, the conventional sealing device of this type has a problem that not only has always followed the risk, but also the productivity is lowered since the connection of the sewage pipes of the heavy chain has to be sealed by hand one by one. In addition, the conventional sealing device has another problem that the waste water is easily leaked by the waste water flowing continuously between the sewage pipe and the sewage pipe is contaminated with soil and groundwater.

Therefore, the present invention improves productivity by easily sealing the connection between the sewage pipe and the sewage pipe through which the domestic (or industrial) waste water flows, and a new form that can block the leakage of waste water through the connection part of the sewage pipe even after continuous use. The purpose is to provide a sealing device for sewage pipes.

According to a feature of the present invention for achieving the above object, at least one formed on the outer circumferential surface to seal the coupling portion of the first sewer pipe and the second sewer pipe when the one end of the first sewer pipe is connected to one end of the second sewer pipe; A sewage rubber is attached to the coupling groove of the sewage pipe is coupled to the first sewer pipe, the sewer pipe sealing device having a rounded jaw to be caught in the front end of the first sewer pipe inserted into the second sewer pipe on the front surface is formed of a hard rubber material A first coupling part coupled to an outer circumferential surface of one end of the first sewer pipe inserted into the second sewer pipe; A second coupling part attached to the outer circumferential surface of the first coupling part by a water-expandable rubber material and integrally formed and adhered to the inner surface of the second sewer pipe when in use; At least one blade piece formed on an outer circumferential surface of the second coupling part and formed at a predetermined interval and a height with a space having a predetermined size therebetween, and compressed to the space when the first sewer pipe is coupled to the second sewer pipe; Include.

It is sectional drawing which shows the coupled state.

1 and 2, when connecting the first sewage pipe 10 and the second sewage pipe 12 uses a sewer pipe sealing device 20 according to an embodiment of the present invention. At this time, one end of the first sewage pipe 10 is fitted to one end of the second sewage pipe 12 is coupled. Therefore, the sewer pipe sealing device 20 is inserted into the outer peripheral surface of one end of the first sewer pipe 10 and inserted into the second water pipe 12. By the sewer pipe sealing device 20 as described above, the coupling portion between the first sewer pipe 10 and the second sewer pipe 12 is sealed.

The sewer pipe sealing device 20 includes a first coupling part 22 and a second coupling part 24. The first coupling portion 22 is formed of a hard rubber material. The first coupling portion 22 is coupled to an outer circumferential surface of one end of the first sewer pipe 10 inserted into the second sewer pipe 12. Therefore, the inner surface of the first coupling portion 22 has a shape corresponding to the outer circumferential surface of the first sewer pipe 10. In the embodiment of the present invention, since the outer circumferential surfaces of the first and second sewer pipes 10 and 12 are formed in a circular shape, the inner surface of the first coupling portion 22 is also formed in a circular shape. The second coupling part 24 is formed of a water expandable rubber material. This water-expandable rubber material is a rubber material that has a property of expanding when a liquid is absorbed. The second coupling part 24 is attached to the outer circumferential surface of the first coupling part 22 and integrally formed with the first coupling part 22. The second coupling part 24 is in close contact with the inner surface of the second sewer pipe 12 when the first sewer pipe 10 is coupled to the second sewer pipe 12. Meanwhile, blade blades 26 are formed on the outer circumferential surface of the second coupling portion 24. The blade pieces 26 are formed at predetermined intervals and heights with a space 28 having a predetermined size therebetween. The blade pieces 26 allow for further sealing between the first sewer pipe 10 and the second sewer pipe 12. In this case, since the blade pieces 26 are formed of a water-expandable rubber material as the second coupling part 24, leakage of sewage may occur between the first sewer pipe 10 and the second sewer pipe 12. When inflated, the sewage will not leak out.
