Polyethylene polypropylene fiber composite waterproof roll laying construction method

Abstract

The invention relates to a polyethylene polypropylene fiber composite waterproof roll laying construction method. The polyethylene polypropylene fiber composite waterproof roll laying construction method adopts the following waterproof roll laying device, and the waterproof roll laying device comprises a vertical frame, a support frame, a clamping and pressing plate, a pressing mechanism and a rolling mechanism; and the polyethylene polypropylene fiber composite waterproof roll laying construction method adopting the waterproof roll laying device comprises the following steps: S1, cleaning a construction site; S2, pretreating waterproof rolls; S3, rolling the waterproof rolls; and S4, laminating the waterproof rolls. According to the construction method, the following problems existing when waterproof rolls are manually laid in the prior art that the laying difficulty of the side edges of the waterproof rolls is high, the waterproof rolls at the upper end and the side surfaces of a square pit need to be manually flattened and compacted respectively, the waterproof rolls can be displaced and deflected when being laid, consequently the laying effect of the waterproof rolls is poor, the waterproof rolls are prone to wrinkling during laying, and the waterproof performance of the waterproof rolls in the later period is affected can be solved.

Description

technical field [0001] The invention relates to the field of waterproof coiled material processing, in particular to a construction method for laying polyethylene polypropylene fiber composite waterproof coiled material. Background technique [0002] Polyethylene polypropylene composite waterproof membrane is a new type of waterproof membrane made of raw polyethylene synthetic polymer materials, adding anti-aging agents, stabilizers, adhesion promoters, etc. Coil. [0003] Polyethylene polypropylene fiber composite waterproof membranes are laid by lap joints; when waterproof construction is carried out on square pit structures such as storage pits and water storage pits, the laying of waterproof membranes on the side of the square pit is the entire square pit. The main points and difficulties of the waterproof treatment of the structure. When laying the waterproof membrane on the side of the square pit, the waterproof membrane is usually manually compacted and pasted on the...

AI Technical Summary

Problems solved by technology

[0004] It is difficult to pave the side of the waterproof membrane. It is necessary to manually flatten and compact the waterproof membrane on the upper end and the side of the square pit. Poor, when the waterproof membrane is paved, it is prone to wrinkles, which will affect the waterproof performance of the waterproof membrane in the later stage
