Waterproof roll for tunnel roof and preparation method thereof

Abstract

The invention provides a waterproof roll for a tunnel roof and a preparation method of the waterproof roll. The waterproof roll comprises a first waterproof plate, a sandwich plate is adhered to the bottom of the first waterproof plate through a first sealant; a second waterproof plate is adhered to the bottom of the sandwich plate through a second sealant; reinforcing blocks are integrally formedon the opposite peripheries of the first waterproof plate and the second waterproof plate, reinforcing grooves matched with the reinforcing blocks in a clamped mode are formed in the periphery of thetop and the periphery of the bottom of the sandwich plate, and the two sides of the center of the top and the two sides of the center of the bottom of the sandwich plate are coated with a strong waterproof glue used in cooperation with the first waterproof plate and the second waterproof plate. Through cooperation of the reinforcing blocks and the reinforcing grooves, the connecting and fasteningeffect among the first waterproof plate, the sandwich plate and the second waterproof plate can be enhanced, the overall strength between the first waterproof plate and the second waterproof plate isenhanced, and the water seepage prevention effect of the first waterproof plate and the second waterproof plate is enhanced through the strong waterproof glue, water seepage holes and water absorption microbeads.

Description

technical field [0001] The invention relates to the field of tunnel waterproof coiled material, in particular to a waterproof coiled material for tunnel roof and cutting equipment thereof. Background technique [0002] Waterproof membrane is a kind of anti-seepage material made of polymer as the basic raw material. It can prevent liquid leakage and gas volatilization. It is widely used in construction, transportation, subway, tunnel and engineering construction. [0003] When the construction unit is constructing a tunnel, it is necessary to use waterproof membranes to prevent seepage of the underground water layer at the top of the tunnel. However, the traditional waterproof membranes have poor strengthening effects and cannot offset the stress of the tunnel. Over time, it is easy to cause waterproof rolls The material is extruded and deformed. [0004] At present, tunnel construction mainly uses waterproof boards or asphalt self-adhesive polymer waterproof membranes for w...

Problems solved by technology

[0003] When the construction unit is constructing a tunnel, it is necessary to use waterproof membranes to prevent seepage of the underground water layer at the top of the tunnel. However, the traditional waterproof membranes have poor strengthening effects and cannot offset the stress of the tunnel. Over time, it is easy to cause waterproof rolls extruded material

[0004] At present, tunnel construction mainly uses waterproof boards or asphalt self-adhesive polymer waterproof membranes for waterproof construction. The construction progress of waterproof boards in tunnel construction is slow and difficult; asphalt self-adhesive waterproof membranes are dense and heavy during construction, which is time-consuming and laborious. , and not an environmentally friendly material
