Waterproof plugging process for cable hole

Abstract

The invention discloses a waterproof plugging process for a cable hole. The waterproof plugging process comprises the following specific steps: polishing the inner side wall of the cable hole to be smooth; prefabricating a sealing plate, cutting inserting holes in the sealing plate, prefabricating a sleeve, welding steel bars to the outer side wall of the sleeve, drilling a plurality of grout penetrating holes in the outer side wall of the sleeve, welding a cover plate to the end wall of the sleeve, cutting through holes and grouting holes in the cover plate; sleeving the sealing plate outsidethe cable, inserting the sealing plate into the cable hole, moving the sealing plate into the cable hole, sleeving the sleeve and the cover plate outside the cable, inserting the sleeve into the cable hole, pushing the sealing plate into the cable hole, and attaching the cover plate to a wall.; injecting the filler into the sleeve from the grouting hole, allowing the filler to enter the cable hole from the slurry penetrating hole, and when the filler overflows from the top of the cover plate, stopping grouting; rotating the sleeve, injecting the filler from the grouting hole, and when the filler overflows from the top of the cover plate, stopping the grouting; repeating for multiple times, and finally sealing the grouting hole by a sealing plug; and waiting for filler drying, thereby reducing the possibility that water overflows from the cable hole.

Description

technical field [0001] The invention relates to the technical field of cable hole plugging, more specifically, it relates to a cable hole waterproof plugging process. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of conductors (at least two in each group). Each group of conductors is insulated from each other and is often twisted around a center. Insulating covering. The cable has the characteristics of internal electrification and external insulation. When installing cables, sometimes it is necessary for the cables to pass through the wall. In order to facilitate installation, the cable holes cut out on the wall are generally larger than the diameter of the cables. After the cables are installed, there will be gaps that are prone to water leakage. important core. [0003] Authorized announcement number is that the Chinese patent of CN1020293C discloses a kind of through-wall cable tube water cut-off plugging tec...

Problems solved by technology

[0004] When using the technology in the prior art, at first on the exposed cable, use hemp silk to stick epoxy glue to make dripping water, then lay bricks and plaster outside the wall to form a mold, and finally pour hot asphalt into the mold, but in long-term use Among them, asphalt is easy to age, and its water resistance performance decreases. At this time, it is easy to cause the anti-water blocking effect to decline, which needs to be improved
