Problems solved by technology

The so-called gas tunnel refers to the tunnel passing through the gas formation. Therefore, as more and more tunnels are built through the gas-containing formation, during the construction and operation of the tunnel, if the management and prevention are not done properly, it is easy to cause major safety accidents.
Nowadays, in order to prevent gas leakage, PVC boards are generally used to fit in the tunnel, but the PVC board is affected by high and low temperature changes, and the joints are hot and cold construction cannot guarantee its strong adhesion, and cannot be bonded to the rock surface of the tunnel. At the same time, the concrete is easily broken under the extrusion, and then loses the gas-proof and waterproof functions, leaving a safety hazard for the tunnel construction. Therefore, a waterproof membrane for gas isolation is urgently needed to meet the requirements of tunnel construction. The rock surface is closely pasted to prevent gas exposure

Abstract

The invention discloses a gas isolation waterproof coiled material in the technical field of coiled materials. The coiled material comprises a coiled material body, the coiled material body comprises a fireproof layer, a grid layer is pasted on the fireproof layer, the grid layer is coated with a waterproof coating, a plastic film layer is pasted on the waterproof coating, a waterproof layer is pasted on the plastic film layer, the lower surface of the fireproof layer and the upper surface of the plastic film are both coated with modified asphalt, the two opposite ends of the coiled material body are rack-shaped sawtooth ends, and the upper surfaces of the sawtooth ends are provided with bonding layers. According to the scheme, the gas isolation waterproof coiled material is provided so as to be tightly attached to the rock surface in the tunnel construction process, and gas is prevented from being exposed.

Description

technical field [0001] The invention relates to the technical field of coiled materials, in particular to a gas isolation and waterproof coiled material and its processing technology. Background technique [0002] The current road construction is developing rapidly, the proportion of tunnels is large, and there are more and more gas tunnels. Gas is a colorless, odorless gas that is insoluble in water, with a relative density of 0.554 and a permeability 1.6 times that of air. The main component is alkanes, of which methane accounts for the vast majority. When it reaches a certain concentration, it can burn or explode. . The so-called gas tunnel refers to the tunnel that passes through the gas formation. Therefore, as more and more tunnels are built through the gas-containing formation, if the tunnel construction and operation are not properly managed and prevented, it is easy to cause major safety accidents. Nowadays, in order to prevent gas leakage, PVC boards are generall...
