It includes the pipe (channel) system itself and various structures on the pipe (channel) system (such as pump stations, reservoirs, pipe bridges, gate wells, sewage inspection wells, rainwater inlets, etc.). Its project investment accounts for the majority of the total investment in the water supply and drainage system project.

[0003] However, in the existing water supply and drainage pipe connection structure, during use, most of the pipes are only connected to each other through flanges. However, the connection point of the pipe is the place where the greatest force is applied. The threaded connection of the flange alone is prone to loosening. In addition, the flange connection method requires welding a flange of a specified specification to the upper end of the pipe, which is cumbersome to operate, and the strength of the welding position is difficult to ensure, which is prone to water leakage. In view of this, there may already be technical means to solve the above problems in the prior art, but this case intends to provide an alternative or replacement technical solution.

[0022] When sealing and splicing the pipe group 1 of the water supply and drainage pipeline, the staff first uses a tapping sleeve to process external threads on the upper ends of the two pipe groups 1, and then the two internally threaded sleeves 2 cooperate with the external threads to fix the two internally threaded sleeves 2 at the specified positions on the upper ends of the two pipe groups 1. The position of the internally threaded sleeves 2 can be adjusted by the provided operating nut 3, and then the sealing sleeve 5 is put on one end of the pipe group 1, and the sealing effect between the pipe group 1 and the sealing sleeve 5 is ensured by the sealing gasket inside the sealing sleeve 5.
