Cable duct bank plugging water-leakage-proof set

Abstract

The invention provides a cable duct bank plugging water-leakage-proof set, which comprises an elastic inner sleeve of a circular truncated cone body, and an elastic outer sleeve sleeving the circular truncated cone body outside the elastic inner sleeve, wherein a large-diameter end of the elastic inner sleeve and a small-diameter end of the elastic outer sleeve are of an integrally-formed structure; a lap-joint seam is formed in the side surface of the elastic outer sleeve, and the lap-joint seam is in a sawtoothed shape; and the outer side wall of the elastic inner sleeve is provided with more than four main keels and auxiliary keels which are adjacent to the main keels. The cable duct bank plugging water-leakage-proof set utilizes the advantage of good elasticity of rubber for sealing a tube opening, effectively solves the problem of insecure sealing caused by irregular tube opening, is simple in structure and convenient to user, can be completed by simple construction, and greatly improves working efficiency.

Description

technical field [0001] The invention relates to a pipe sealing device, in particular to a cable pipe sealing and anti-leakage suit. Background technique [0002] The cable pipe is a cable laying pipe. The material is generally cement, iron pipe or MPP pipe. The cable pipe opening generally needs to be blocked. If it is not blocked, once a pipe well leaks, it will easily lead to water accumulation along the pipe hole It spreads to other pipe wells, and then deteriorates the operating environment of the cable, causing the intermediate head to be soaked in water for a long time, greatly reducing the service life of the cable intermediate head. At present, the pipe holes in the underground opening and closing station are mostly sealed with cement, but cement is a rigid material, once it expands with heat and contracts with cold, it will cause cracks, and the cement is sealed inside the pipe with an irregular shape and poor pressure resistance , In actual work, rainwater often f...

Problems solved by technology

However, the structure of the device is complicated, and the construction process is too cumbersome, which seriously reduces the work efficiency. Due to the non-standard construction, the opening of the cable pipe is often irregular. The extension end is sealed with a wooden plug. Due to the insufficient elasticity of the sealing paste and the wooden plug, it is easy to seal the irregular part of the nozzle. The elasticity is small, and it is not easy to fill the gap caused by the expansion of the cable pipe in time, which will lead to the problem of poor sealing
