Problems solved by technology

However, traditional polymer waterproof membranes, such as polyvinyl chloride waterproof membranes, are made of single-layer polyvinyl chloride, and the compression and deformation resistance of the membrane is poor. Temperature changes cause shrinkage and expansion of the membrane, which is easy Cause the membrane to break and form micropores, which affects the waterproof performance of the waterproof membrane

Embodiment Construction

[0015] It can be seen from the attached drawings that the tunnel anti-seepage and puncture-resistant PE, EVA, and glass fiber waterproof membranes are composed of surface layer-isolation film protection layer 1, middle layer-PE layer, bottom layer-adhesive sealant layer 3, and the gap between each layer It is bonded together by heat and pressure during the production process.

[0016] The protective layer of the isolation film is polyvinyl chloride film, polyester film or release paper or other films with isolation protection, the thickness of the isolation film protective layer is 0.15-0.2cm, and the thickness of the adhesive sealant layer is 0.1-0.5cm.

[0017] The PE layer contains impact-resistant and puncture-resistant modifier EVA, and glass fiber is added to improve its breaking strength. The thickness of the PE layer is 0.5-3.0cm.

[0018] There are two construction methods for tunnel impermeable and puncture-resistant PE, EVA, and glass fiber waterproof membranes. One...

Abstract

An impervious puncture-resistant PE, EVA and glass fiber waterproof roll for tunnels and a construction method of the impervious puncture-resistant PE, EVA and glass fiber waterproof roll belong to the technical field of waterproof materials. The impervious puncture-resistant PE, EVA and glass fiber waterproof roll comprises an isolating membrane protective layer, a PE layer and an adhesive sealant layer, wherein the PE layer is arranged between the isolating membrane protective layer and the adhesive sealant layer, and all the layers are bonded into a whole via hot-pressing; the PE layer is 0.5-3.0 mm in thickness, and the isolating membrane protective layer is a polyvinyl chloride film, a polyester film, isolation paper or other films with an isolation protection function. The impervious puncture-resistant PE, EVA and glass fiber waterproof roll for tunnels is used for waterproof construction, and is simple in structure, convenient to construct and good in waterproof effect. The construction method is very simple and feasible, is convenient to operate and has a wide market space.

Description

technical field [0001] The invention relates to a waterproof coiled material and a construction method thereof, in particular to a tunnel anti-seepage and anti-puncture PE, EVA, glass fiber waterproof coiled material and a construction method thereof, belonging to the technical field of waterproof materials. Background technique [0002] Waterproof materials play an important role in building construction. In the construction of roads, bridges, roofs or buildings that need to be waterproofed, a large amount of waterproof materials need to be paved to prevent leakage. The quality and service life of waterproof materials directly affect the quality of the entire construction project. Traditional waterproof materials such as asphalt linoleum are gradually being eliminated due to their shortcomings such as toxicity and poor high and low temperature resistance. At present, polymer waterproof membrane has been widely used in recent years because of its excellent waterproof and co...
