Compared with the prior art, the problem of water leakage of a water stop project can be completely solved after the device is used.

Description

Technical Field

[0001] The utility model relates to a wall-penetrating screw rod, in particular to a water engineering leak-proof plug which is installed at both ends of the wall-penetrating screw rod during water engineering construction and is used to prevent water leakage. Background Art

[0002] As we all know, in order to prevent water leakage in water conservancy projects, a waterproof pad is added to the middle of the traditional through-wall screw during construction. Although the effect of adding the waterproof pad is much better than the traditional through-wall screw alone, it does not completely solve the problem of water leakage in water conservancy projects. Therefore, designing a water conservancy project anti-leakage plug that can completely stop water leakage in water conservancy projects is a technical problem that needs to be solved at present. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a water engineering leak-proof plug which can completely solve the problem of water leakage in water engineering.

[0004] The technical solution of the present invention to solve the technical problem is:

[0005] The anti-leakage plug for water conservancy projects is composed of a plug body, and is characterized in that the plug body is a frustum of a cone with a stepped outer conical surface and a cylinder in the middle, a central blind hole matching the waterproof bolt is provided on the end face of the small head end of the frustum of the cone, an O-ring I is mounted on the middle cylinder of the frustum of the cone, and an O-ring II is provided at the cross section of the frustum of the cone.

[0006] As a technical solution of the utility model, an annular groove for installing an O-ring is provided on the end surface of the small end of the truncated cone, and the O-ring II (2) is installed in the annular groove.

[0007] As a technical solution of the utility model, the central blind hole is an internal threaded blind hole matching the external thread of the end of the waterproof bolt.

[0008] As a technical solution of the utility model, a process hole for a tool used to tighten the plug body is provided on the end surface of the large head end of the truncated cone.
