Embodiment Construction

[0012] The invention discloses a post-drilling waterproof treatment method for a waterproof structure, comprising: processing a sleeve assembly according to the size of the required opening, and the sleeve and the flange need to be fully welded on both sides. Steel pipe in flanges and assemblies can be purchased at plumbing supply stores.

[0013] Open the structure. After the hole is completed, the concrete surface around the hole needs to be polished to ensure that the flange can fully contact the structure.

[0014] Temporarily fix the flange sleeve to the opening, and place the flange on the back surface of the structure. After the simple fixation, the post-planting bolts are positioned and drilled, and the galvanized bolts are implanted into the structure with planting glue (the construction process is the same as planting bars).

[0015] After the planting glue is completely cured, first install a water-swelling water-stop strip (point sticking method) on the inner side...

Abstract

The invention relates to a pipe for opening holes in a wallboard. A post-drilling waterproof treatment method for a waterproof structure, including: processing the sleeve assembly according to the size of the required opening, the sleeve and the flange need to be fully welded on both sides; opening the structure, and after the opening is completed, the concrete around the hole needs to be Polish the surface to ensure that the flange can fully contact the structure; temporarily fix the flange sleeve on the opening part, and place the flange on the back surface of the structure; after simple fixing, perform positioning and drilling of post-planted bolts, and place galvanized bolts Use planting glue to implant into the structure, and the construction process is the same as that of planting bars; after the planting glue is completely cured, first install a circle of water-swelling water-stop strips inside the bolts, then install waterproof rubber rings, and finally install flange waterproof sleeves After the casing is aligned, the bolts are fastened, and the single pad and single cap are tightened one by one in the form of cross diagonals; after the fastening is completed, the flexible asphalt ointment is filled between the casing and the structure from the side facing the water. Can. The waterproof effect of the present invention is stable.

Description

technical field [0001] The invention relates to the opening and routing of wall boards, in particular to the opening of waterproof structures. Background technique [0002] In the construction of new buildings and the renovation of old buildings, it is often necessary to open holes in the waterproof structure wall panels to run pipes. The usual method for new buildings is to pre-embed casings with water-stop rings before concrete pouring, and for old buildings to be renovated. The method of plugging and filling with flexible waterproof material after drilling through the pipe is adopted. For new buildings, once the water-stop casing is missing during construction, the treatment method will be remedied according to the method of old building renovation, but this remedial method cannot effectively guarantee the waterproof effect of the rear opening. Contents of the invention [0003] The present invention aims to solve the above-mentioned defects, and provides a waterproof ...
