Abstract

The invention belongs to the technical field of waterproofing, and relates to a waterproof roll and a preparation method and a construction method thereof. The waterproof roll comprises a resin sheet layer, a non-asphalt-based polymer self-adhesive layer and an interface bonding layer which are sequentially arranged, and the light transmittance of the waterproof roll is larger than or equal to 45%. According to the visual waterproof roll, light can penetrate through the roll to see through the gasket, and when the light transmittance of the roll is larger than or equal to 45%, good visibility is achieved for warm-color gaskets such as orange gaskets and red gaskets.

Description

technical field [0001] The invention belongs to the technical field of waterproofing, and in particular relates to a waterproof coiled material, a preparation method and a construction method of the waterproof coiled material. Background technique [0002] Since tunnels are constructed using the mining method or the new Austrian method, the method of setting a waterproof layer between the shotcrete layer and the secondary lining is generally used to solve the waterproof problem of the composite lining. The waterproof layer constructed usually adopts PVC, EVA, ECB, LDPE and other waterproof boards. These traditional flashings have a smooth surface and cannot form an effective bite with the secondary lined concrete. Once the waterproof membrane is damaged or the welding is not firm, there will be a phenomenon of "water channeling" between the waterproof layer and the second lining concrete, and then enter the tunnel through concrete cracks and gaps. [0003] In recent years,...
