Construction method of polymer self-adhesive film waterproof roll capable of being constructed in rainy season

Abstract

The invention discloses a construction method of a polymer self-adhesive film waterproof roll capable of being constructed in a rainy season. The construction method comprises the following steps of 1) cushion layer construction, 2) base layer cleaning, 3) roll plane laying, 4) roll vertical face laying, 5) roll long edge lap joint, 6) roll short edge lap joint, 7) pile head treatment, 8) internaland external corner treatment, 9) anchor rod treatment, and 10) subsequent rebar binding and concrete pouring. According to the construction method, a back face lap joint adhesive covering layer is additionally arranged on the long edges of the roll, the long edges are in lap joint to form lap joint of adhesive and adhesive, the short edges are in lap joint by pasting two kinds of matched polymerself-adhesive tape, and therefore the requirement for the rainy condition and even the open water construction environment is met, and the anchor rod joint part is prevented from leaking through measures such as a water swelling water stop ring.

Description

technical field [0001] The invention relates to the field of waterproof coiled materials, in particular to a construction method for polymer self-adhesive film waterproof coiled materials which can be constructed in rainy seasons. Background technique [0002] With the development of engineering technology and the increasingly urgent demand for underground space, underground buildings have developed unprecedentedly, such as common underground garages, underground commercial streets, subways, tunnels, and comprehensive utility corridors. my country, especially the area south of the Yangtze River, is affected by the southeast monsoon of the Pacific Ocean, and there is a rainy season that lasts for more than two months every year. For the current extremely critical waterproofing works of underground buildings, especially the waterproofing of the bottom slab at the deepest buried depth, it is often faced with rainy days. Operation, the wet base surface in rainy season, and even t...

Problems solved by technology

[0003] Traditionally used waterproof membranes bonded to the base surface (such as SBS modified asphalt waterproof membranes, EPDM EPDM waterproof membranes, etc.) need to be clean, dry (moisture content ≤ 9%), flat base surface Due to the extremely high requirements on the base surface, the actual waterproof effect is relatively poor. At present, the application in floor construction is gradually replaced by polymer pre-laid waterproof membranes.

[0004] The current polymer pre-laid waterproof membrane has been gradually matured i
