Description

Dual-purpose plugging member for underwater pipeline

technical field

The utility model belongs to the technical field of water conservancy engineering tools, and in particular relates to a dual-purpose plug member for underwater pipelines that can quickly complete the reinforcement and transformation of underwater discharge pipes, effectively shorten the construction period, and improve work efficiency.

Background technique

When reinforcing the water discharge pipes and water discharge holes of the reservoir, in order to meet the construction requirements, it is necessary to carry out interception construction for the pipes (holes) underwater. At present, the upstream cofferdam method is generally used to change the underwater construction to land construction; the disadvantage is that the project investment is large, the construction period is long, and the cofferdam needs to be removed after the construction is completed. The underwater pipe dual-purpose plug member can effectively solve the above problems, and is of great significance to the reinforcement of the water discharge pipe. After the production of the dual-purpose plug for underwater pipelines is completed, divers are required to place the dual-purpose plug components for underwater pipelines underwater according to the construction requirements into the original pipe opening, and they can be fixed in the pipeline by themselves under the action of water pressure, and the downstream of the pipeline can be opened. The valve releases the water in the pipeline, and the construction work can be carried out. After the construction is completed, close the pipeline valve, open the upstream valve of the component, and remove the upstream cover after the water body fills the pipeline, and the project construction is completed.

Contents of the invention

The purpose of the utility model is a dual-purpose plug member for underwater pipelines designed to overcome the construction difficulties of water discharge pipes. The technical solution adopted to realize the purpose of the utility model is: a dual-purpose plug member for underwater pipelines, which is characterized in that: the member is provided with an inner pipe, and a cover is provided in cooperation with the inner pipe, and a valve is arranged on the cover. The inner ring of the cover is provided with a rubber pad, the inner pipe is provided with a steel mesh, the outer wall of the inner pipe is wrapped with a certain thickness of dry kelp, and the end of the inner pipe is provided with a steel ring. This component is placed on the upstream inlet section of the water discharge pipe, and the cover is fixed on the original pipeline, the valve is closed, and the water flow leading to the pipeline is closed, so that the downstream pipeline can be constructed; the valve on the cover is opened to fill the pipeline with water , At this time, the water pressure on both sides is equal, the cover is removed, the inside of the dual-purpose plug of the underwater pipeline remains unblocked, and the original pipeline returns to the normal working state. Therefore, when the cover is working, the pipeline is in a cut-off state; when the cover is removed, the pipeline returns to the normal working state; the dual-purpose purpose of the component is achieved.

The utility model has the advantages of novel structure, convenient production and easy operation, and the efficiency can be greatly improved after being installed at the upstream inlet of the discharge pipe.

Detailed ways

Referring to the accompanying drawings, a dual-purpose plug member for underwater pipelines is characterized in that: the member is provided with an inner pipe 1, and a cover 2 is provided in cooperation with the inner pipe 1, and a valve 3 is arranged on the cover 2, and the cover 2 The inner ring is provided with a rubber pad 5, the inner pipe 1 is provided with a steel mesh 4, the outer wall of the inner pipe 1 is wrapped with a certain thickness of dry kelp 6, and the end of the inner pipe 1 is provided with a steel ring 7.

During use, the utility model is placed on the upstream inlet of the original steel pipe 8 by divers in still water, and after about 4 hours, the dry kelp 6 expands to produce a water-stopping effect, and the downstream valve of the pipeline is opened to remove the water flow in the original pipeline. Pipeline construction is carried out downstream. After the construction is completed, close the downstream gate valve, unscrew the valve 3, and put water into the pipeline. After the water is full, the upstream and downstream water pressure of the plug member is the same. The original pipeline construction was completed and entered normal working condition.
