[0002] Cement pipe is a pre-set pipe made of cement and steel bars using the principle of centrifugal force of electric poles. Cement pipe is also called cement pressure pipe and reinforced concrete pipe. It can be used as a sewer pipe in urban construction foundation, can discharge sewage, flood control and drainage, and is also used as a water pipe and farmland machine well in some special factories and mines. Tongue and groove cement pipe is a common cement pipe, which is characterized by a tongue at one end of the pipe body and a socket at the other end. The function of the tongue and socket is to make the pipeline connection more secure and less prone to leakage and loosening. The cement pipe tongue and groove sealing structure is mainly used to ensure the sealing of the pipeline interface to prevent sewage outflow and pipeline damage. The existing cement pipe tongue and groove sealing structure usually uses a layer of sealing ring for sealing connection, but due to long-term external forces such as water flow and soil pressure, it is easy to cause sewage outflow and pipeline damage, reducing the overall sealing and protection effect. Utility Model Content

Double sealing is performed on the inside and further sealing is performed on the outside, and a pressure-resistant module and an anti-slip module are provided for reinforcement and protection, so that the first tube body and the second tube body are not easily affected by external forces, thereby achieving a better sealing effect.

[0006] Preferably, the sealing assembly includes a sealing module, a pressure-resistant module and an anti-slip module. The front and rear ends of the sealing module are symmetrically provided with pressure-resistant modules for shock absorption, and the left and right ends of the sealing module are symmetrically provided with two groups of anti-slip modules for preventing the sealing module from shifting. By setting the sealing module, the outer side of the connection between the first tube body and the second tube body can be externally sealed, and the front and rear ends of the multi-plate can be protected by setting the pressure-resistant module.

[0012] Beneficial effects of the utility model:

[0013] 1. Compared with the traditional cement pipe tongue and groove sealing structure, a layer of sealing ring is usually used for sealing connection. However, due to the long-term external force such as water flow and soil pressure, it is easy to cause sewage outflow and pipeline damage, reducing the overall sealing protection effect. By setting the first sealing ring and the second sealing ring, the inner side of the connection between the first pipe body and the second pipe body can be double-sealed, which has a better sealing effect than the sealing structure set by the traditional single-layer sealing structure. In addition, by setting the sealing component on the outside of the connection between the first pipe body and the second pipe body, the sealing can be further fixed from the outside, which can enhance the stability of the connection between the first pipe body and the second pipe body and further enhance the sealing effect. The sealing mold group can perform external sealing on the outer side of the connection between the first tube body and the second tube body. The outer side of the connection between the first tube body and the second tube body can be clamped by setting a clamping plate. The tightness of the clamping can be adjusted by setting a first bolt and a first nut. The sealing can be enhanced by setting a sealing layer on the inner side of the clamping plate to prevent water from flowing in from the gap. The upper and lower ends of the clamping plate can be protected by setting an anti-collision ring plate on the outer side of the clamping plate. In addition, by setting multiple groups of springs around the clamping plate and the anti-collision ring plate, the elasticity of the springs can play a certain buffering role in the event of collision or extrusion, so that the external force that finally reaches the clamping plate is greatly weakened, thereby playing a shock-absorbing role.

[0014] 2. By setting up the anti-pressure module, the front and rear ends of the multi-ply plate can be protected. By setting up the main elastic plate, it can be buffered and shock-absorbing when collision and extrusion occur. By setting up auxiliary elastic plates on the inner and outer sides of the main elastic plate, the rebound effect can be enhanced to prevent the main elastic plate from being crushed by excessive external force. By opening second mounting holes matching the first mounting holes on the anti-collision ring plate on the mounting blocks at both ends of the main elastic plate, the anti-pressure module and the sealing module can be detachably connected to facilitate installation and replacement. By setting up the anti-slip module, the first tube body and the second tube body can be clamped from both ends for support, thereby reinforcing the sealing module to prevent the sealing module from shifting and affecting the sealing effect. By setting up the first connecting block, the support and the second connecting block that are rotatably connected to each other, corresponding adjustments can be made according to the thickness of the actual pipeline. By setting up a gripping clamp adjusted by the second bolt and the second nut, the clamping tightness can be adjusted according to actual needs. By setting an anti-slip layer on the inner side of the gripping clamp, friction can be increased, so that the gripping clamp is not easy to slide or shift, and the anti-slip effect is better.

[0028] When working, firstly, the first sealing ring 4 is put into the anti-slip groove 7 of the tongue-and-groove end 6 of the second tube body 2, and then the second sealing ring 5 is put on the outside of the first sealing ring 4, and then the non-tongue-and-groove end 6 of the first tube body 1 and the tongue-and-groove end 6 of the second tube body 2 are mutually sleeved and clamped together;

[0029] Then, two sets of clamping plates 304 are symmetrically fitted on the outer side of the connection between the first tube body 1 and the second tube body 2, and the left and right ends of the two sets of clamping plates 304 are fixed together by the first bolt 309 and the first nut 310, so that the sealing layer 305 is tightly fitted with the outer sides of the first tube body 1 and the second tube body 2 to seal the connection;
