A kind of wall cable sealing method

Abstract

The invention discloses a wall body cable blocking method, comprising the following steps: step 1: fixedly disposing a support in an opening of a wall body to form multiple partitions to separate multiple cables from each other; step 2: using an inflation sealing bag to enclose the cables to be inserted in an anchor ear PVC (polyvinyl chloride) tube, and implementing extruding the cables using the inflation sealing bag and fully expanding to fill gaps by means of inflation expansion; step 3: respectively mounting a baffle mold at each of two ends of the opening of the wall body; step 4: injecting a fireproof and waterproof filler into an injection hole of each baffle mold to fill the gaps; and step 5: after the fireproof and waterproof filler is solidified, removing the baffle mold. The method may achieve separating arrangements of multiple cables in a hole passing through a wall, while applying effective gap filling; by adopting a flexible mounting process, good sealing, waterproof, fireproof, ratproof and anti-termite functions are provided; mounting and maintenance are fast and convenient; service life is long; the accident rate is low; and maintenance costs are lowered.

Description

technical field [0001] The invention relates to the technical field of electric power safety, in particular to a wall cable sealing method. Background technique [0002] In the waterproof sealing process of the cable duct wall hole, the inflatable duct sealing bag can be used to realize the sealing function of the pipeline cable entrance by using the principle of inflation and expansion. This sealing method is quick to install, easy to remove, and the sealing effect is also good. High-quality fire-resistant and waterproof performance can effectively waterproof, prevent seepage, prevent pests and other unfavorable factors for cables and computer rooms. However, as far as the current actual installation experience is concerned, when multiple cables are blocked through the wall, the individual cables are not placed separately, and the multiple cables are generally poured with cement. This pouring method is difficult in construction technology and quality. The reliability is po...

Problems solved by technology

However, as far as the current actual installation experience is concerned, when multiple cables are blocked through the wall, the individual cables are not placed separately, and the multiple cables are generally poured with cement. This pouring method is difficult in construction technology and quality. Poor reliability, easy weathering of clay, poor durability

If an inflatable pipe sealing bag is used for uniform wrapping and sealing, this sealing method has low structural strength, is not suitable for the flexible installation process of cables, is not conducive to withstand small-scale displacement of cables, and has weak earthquake resistance. It greatly weakens the protective effect on cables, and is not conducive to subsequent maintenance and replacement operations. In some installation processes, multiple wall holes corresponding to multiple cables are opened in advance on the wall and equipped with sleeves for sealing installation. , this installation method has poor application flexibility, complex installation process, low operating efficiency, high cable failure rate and high installation and maintenance costs
