[0002] Water conservancy projects are projects built to eliminate water disasters and develop and utilize water resources. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, ferries, valves, fishways, and other types of hydraulic structures, such as the construction of sewage pipes.

[0003] In the prior art, sewage pipes are generally concrete pipes, stainless steel pipes, PE corrugated pipes, etc., among which PE corrugated pipes have good corrosion resistance and high pressure resistance, and PE corrugated pipes have good softness and are relatively convenient to construct. When the prior art Chinese PE pipes are docked, a sealing ring is generally installed at one end of the PE pipe and then inserted into the pipe joint of another pipe for docking. In order to ensure the sealing of the pipe connection, the sealing ring is generally tight, and it is easy to be misaligned during the plug-in process, resulting in reduced sealing.

[0006] The airtight component comprises an airbag, an annular airbag is fixedly installed in the pipe joint, and the air inlet of the airbag is located on the outside of the pipe joint.

[0007] A groove is formed on the top surface of the pipe joint, a through hole is formed on the bottom surface of the groove, and a valve core connected with the air bag is fixedly installed in the through hole.

[0008] An annular groove is formed on the inner wall of the pipe joint, and the airbag is fixedly installed in the annular groove. After the airbag is inflated, it can fit tightly with the outer side of the second corrugated pipe.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. When the device is in use, the sealing ring and the airbag cooperate with each other to achieve double sealing of the connection between the first bellows and the second bellows, thereby improving the sealing effect of the interface;

[0011] 2. The airbag has good deformation ability during use. Through inflation, the airbag can make adaptive changes to its own shape according to the contact position with the second bellows, thereby improving the sealing performance of the device. BRIEF DESCRIPTION OF THE DRAWINGS
