Plugging method aiming at cables

Abstract

The present invention discloses a plugging method aiming at cables. The method comprises the following steps: the step 1: fixing arranging supports at a circular output input hole in an inspection well to form a plurality of partitions for separating the cables from each other; the step 2: flexible waterproof adhesive tapes are arranged at the intervals between each partition; and the step 3: employing a fireproof air inflation sealing bag to wrap the cables, the fireproof air inflation sealing bag fully extrude the cables and the flexible waterproof adhesive tapes through air inflation expansion so as to realize the complete filling of the gaps between the partitions. The plugging method aiming at cables performs separation arrangement when the cables or optical cables are arranged in the circular output input hole in the inspection well, applies effective gap filling and has good sealing waterproof, fireproof and rat and ant prevention functions, so that the installation and maintenance are convenient and rapid, the service life is prolonged, and the accident rate is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of cable duct sealing, in particular to a sealing method for multiple cables based on a circular output and input hole in a manhole. Background technique [0002] In the circular output and input holes in power cables and communication manholes, when installing cables or optical cables, an inflatable pipe sealing bag can be used to seal the pipe hole by using the principle of inflation and expansion. It is widely used in plastics, cement and steel. Pipes of hard materials. This plugging method is quick to install, easy to remove, and has a good sealing effect. It has high-quality fire resistance and waterproof performance, and can avoid the adverse effects of accumulated water, sediment, mice, etc. on the pipeline environment. However, based on the current actual installation experience Look, when sealing multiple cables or optical cables, each cable is not placed separately. Usually, an inflatable pipe sea...

Problems solved by technology

This plugging method is quick to install, easy to remove, and has a good sealing effect. It has high-quality fire resistance and waterproof performance, and can avoid the adverse effects of accumulated water, sediment, mice, etc. on the pipeline environment. However, based on the current actual installation experience Look, when sealing multiple cables or optical cables, each cable is not placed separately. Usually, an inflatable pipe sealing bag is used to wrap and seal. This sealing method has low structural strength and is not suitable for the flexibility of cables. The modernized installation process is not conducive to withstand the small-scale displacement of the cable, and the anti-seismic ability is weak, which greatly weakens the protection effect on the cable and is not conducive to subsequent maintenance operations.
