Mechanical fixing construction process of waterproof coiled material

Abstract

The invention provides a mechanical fixing construction process of a waterproof coiled material. The mechanical fixing construction process comprises the following steps of cleaning a base layer, laying a polyethylene film vapor barrier layer, laying a thermal insulation layer, repairing a seam, laying the waterproof coiled material and performing first-time flattening treatment, performing second-time flattening treatment, fixing the waterproof coiled material, performing lap joint of the waterproof coiled material and performing joint strengthening treatment. According to the mechanical fixing construction process of the waterproof coiled material, the degree of closure between the polyethylene film vapor barrier layer and the base layer can be improved by adopting a method of vacuum pumping while using a pressure roller for flattening; moisture in concrete structural holes of the base layer can be removed by using a strong air drying method to blow and dry the surface of the base layer, and the drying property of the base layer is improved, so that the vapor barrier effect between the polyethylene film vapor barrier layer and the base layer is improved, the waterproof effect isbetter, the waterproofness of the waterproof coiled material after being fixed is maximized without increasing the larger cost, and the fixing stability of the waterproof coiled material on a construction site is high.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a construction technique for mechanically fixing waterproof coiled materials. Background technique [0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering basis The leak-free connection with the building is the first barrier for the waterproofing of the entire project and plays a vital role in the entire project. [0003] In the existing waterproof construction projects, the waterproof membrane generally adopts the method of mechanical fixing construction to fix the waterproof membrane, but in the existing waterproof membrane mechanical fixing construction method, the waterproof membrane still has the problem of insufficient fixation. The final waterproof membrane is prone to ed...

AI Technical Summary

Problems solved by technology

[0003] In the existing waterproof construction projects, the waterproof membrane generally adopts the method of mechanical fixing construction to fix the waterproof membrane, but in the existing waterproof membrane mechanical fixing construction method, the waterproof membrane still has the problem of insufficient fixation. The final waterproof membrane is prone to edge warping. If a large number of fixing nails are used to fix the waterproof membrane, too many fixing holes will destroy the waterproof performance of the waterproof membrane, which may cause water seepage. The closure of the space is not good enough, and it is still prone to water seepage. The laying of the waterproof membrane on the thermal insulation layer will also cause the problem of insufficient closure and sealing due to the problems of the fixing parts and the fixing gasket, which directly affects the waterproof of the waterproof membrane. performance
