Description

Technical Field

[0001] The utility model relates to the technical field of concrete drainage pipes, in particular to a corrosion-resistant reinforced concrete drainage pipe. Background Art

[0002] Concrete pipes are pipes made of concrete or reinforced concrete, used to transport fluids such as water and oil. They can be divided into four types: plain concrete pipes, ordinary reinforced concrete pipes, self-stressed reinforced concrete pipes and prestressed concrete pipes.

[0003] The corrosion resistance of existing reinforced concrete drainage pipes is poor. After long-term use, the inner wall of the drainage pipe is easily corroded and broken, resulting in leakage of the drainage pipe. In the daily use of existing reinforced concrete drainage pipes, the joints of the two pipes are prone to leakage, which makes the drainage pipes poorly sealed, resulting in the disadvantage that the reinforced concrete drainage pipes cannot be used and are inconvenient for staff to use. For this reason, we propose a corrosion-resistant reinforced concrete drainage pipe. Utility Model Content

[0011] Preferably, the inner walls of the first pipe and the second pipe are both provided with a corrosion-resistant layer, and the material of the corrosion-resistant layer is epoxy resin anti-corrosion coating.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the sealing gasket and the round shell are placed at the connection between the first pipe and the second pipe, the shaft is rotated by the shaft handle, the threaded rod moves during the rotation, the arc plate and the connecting plate move, the arc plate contacts the sealing gasket, and the sealing gasket is pressed tightly at the connection between the first pipe and the second pipe, and the telescopic rod can be driven to slide inside the telescopic sleeve by the movement of the connecting plate, so that the arc plate will not rotate when it moves, and the corrosion-resistant layer is provided, and the material of the corrosion-resistant layer is epoxy resin anti-corrosion coating, so that the first pipe and the second pipe are connected.
