Description

Technical Field

[0001] The utility model relates to a water conservancy project, in particular to a drainage pipeline used in the water conservancy project. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. However, existing water conservancy projects and drainage projects are not easy to connect and install. During the installation process, the fixing holes between the pipes cannot be quickly connected, which wastes a lot of time during installation. At the same time, they are not corrosion-resistant. The inside and outside of the pipes are in contact with corrosive liquids and gases for a long time, which causes corrosion and rust to the entire pipe, reducing its service life.

[0003] For example, the publication number CN201922016800.3 discloses "A drainage pipe for water conservancy projects", which is coordinated by a pipe body, a first mounting ring, a second mounting ring, a mounting hole, a docking groove, a docking ring, a clamping hole, a clamping rod, a spring, a connecting plate, a steel body, a first protective layer, a second protective layer, an inner corrosion-resistant layer, a waterproof layer, a heat-resistant layer and an outer corrosion-resistant layer. It has the advantages of easy docking installation and corrosion resistance, and solves the problem that the existing drainage projects of water conservancy projects are not convenient for docking installation. During the installation process, the fixing holes between the pipes cannot be quickly docked, which wastes a lot of time during installation. At the same time, it is not corrosion-resistant. The inside and outside of the pipe are in contact with corrosive liquids and gases for a long time, which causes corrosion and rust to the pipe as a whole, reducing the service life.

[0004] When the pipes are butt-jointed, a pull ring is provided, and the pull ring is pulled to facilitate the movement of the clamping rod and fix it to the outside of the pipe installation ring, and the clamping rod is used for alignment. However, it is difficult to support the pipes by relying solely on the clamping rod, and the force of the movement between the pipes is greater than the force of the spring and the clamping rod, so the clamping rod will be consumed too much, which makes it difficult to achieve a good butt-joint installation effect on the pipes.
