High-molecular self-adhesive film waterproof roll welding and lapping structure and construction method

Abstract

The invention discloses a high-molecular self-adhesive film waterproof roll welding and lapping structure and construction method. The structure comprises two pairs of rolls, two welding seams in the lapping edges, a reserved cavity positioned between the two welding seams in the lapping edges, and a sealing adhesive tape covering and bonded to the upper part of the lapping part, wherein the rolls at the lapping part adopt the structures without adhesive layers. The construction method comprises the following steps: taking the two pairs of high-molecular self-adhesive film waterproof rolls in place; removing the self-adhesive layers at the lapping part of the rolls through special equipment, and exposing a base layer plate; lapping the two welding seams in the lapping edges, where the adhesive layers are removed, of the two pairs of rolls through a welding machine; detecting the welding and sealing quality through the cavity reserved between the two welding seams; covering the lapping edges through sealing tapes to enable the lapping edges and the rolls on the two sides to both achieve the property of the self-adhesive film rolls. According to the structure and construction method, through the treatment of the adhesive layers, the rolls can be welded and lapped, the lapping edges can be subjected to airtight detection, the lapping is firm and reliable, and the adaptability is strong.

Description

technical field [0001] The invention relates to the field of underground engineering, and is mainly aimed at a measure for lap joint treatment of polymer self-adhesive film waterproof coiled materials, especially for mining method construction projects in which the coiled material is selected as the outer waterproof layer. Background technique [0002] Construction is a century-old project. In addition to the requirements of firmness, construction projects must be waterproof and moisture-proof. In recent years, there has been an upsurge in the development of underground space across the country, especially in large and medium-sized cities. Civil buildings and public transportation are all asking for space underground, and the scale is getting larger and larger. However, the problem of leakage has followed, and The scope of the leakage and the great harm are beyond our imagination. According to statistics, the average leakage rate of houses nationwide is 65%, and the leakage...
