Abstract

The invention discloses a coating-rolling composite waterproof system structure suitable for an underground side wall. The coating-rolling composite waterproof system structure comprises a coating waterproof layer and a rolling material waterproof layer. The coating waterproof layer is a special thick coating type water-based asphalt waterproof coating for the side wall, and the rolling material waterproof layer is a high-strength anti-puncture asphalt-based self-adhesive waterproof rolling material. According to the coating-rolling composite waterproof system structure suitable for the underground side wall, the technical advantages of the special thick coating type water-based asphalt waterproof coating for the side wall and the high-strength anti-puncture asphalt-based self-adhesive waterproof rolling material are fully exerted, the special thick coating type water-based asphalt waterproof coating for the side wall, the high-strength anti-puncture asphalt-based self-adhesive waterproof rolling material, a bottom plate and a top plate throwing-joint part are firmly bonded together, a full-interface closed waterproof structure is formed, the leakage problem caused by infirm bonding of the joint part due to the material type difference is effectively avoided, and the risk that the waterproof rolling material on the side wall slides and is punctured in the subsequent backfilling process can be avoided.

Description

technical field [0001] The invention relates to the technical field of material application, in particular to a coating-roll composite waterproof system structure suitable for underground side walls, that is, a coating-roll composite waterproof system. [0002] technical background [0003] The waterproof parts of underground buildings generally include the bottom plate, side wall and roof. The floor has a mature pre-paved anti-adhesive construction method, which can be matched with different pre-paved waterproof membranes (including polymer and non-asphalt-based pre-paved waterproof membranes). The pre-paved anti-adhesive waterproof system has two outstanding advantages: ① full Adhesive structure has an advanced concept of no water channeling; ②Pre-paved anti-adhesive has low requirements for the base layer, which is suitable for underground rush construction period, saving money and construction period without a protective layer; there are various mature waterproof construc...
