Construction method using vertical formwork as pre-laid anti-stick self-adhesion waterproof roll base surface

Abstract

The invention discloses a construction method using a vertical formwork as a pre-laid anti-stick self-adhesion waterproof roll base surface. The construction method comprises the following steps thatS1, a cushion layer is poured, and then a single-side formwork-erecting frame is erected according to a formwork control line; S2, a pre-laid anti-stick self-adhesion waterproof roll is laid on the cushion layer, and waterproof rolls at the reserved vertical face part are reserved; S3, the rolls on the vertical face are turned up and smoothly attached to the formwork erecting face, and the rolls and the formwork are fixed with fasteners at the lapped joint positions of the rolls; S4, steel bars of a bottom plate structure are bound according to the design requirements of a drawing, formwork lifting construction is conducted, and concrete is poured; S5, after the concrete meets the strength requirements through maintenance, the fasteners are screwed down and collected, and the formwork is dismantled; and S6, holes, where the fasteners are mounted, in the lapped joint positions of the original rolls are subjected to sealing blockage. The construction cost of engineering is lowered, the waterproof roll on the outer side is not damaged by later dismantling, the construction quality of the waterproof roll is guaranteed, the waterproof effect is good, and actual operability is high.

Description

technical field [0001] The invention relates to the technical field of waterproof coiled material construction for underground structures, in particular to a construction method using a vertical formwork as a base surface of a pre-laid anti-adhesive self-adhesive waterproof coiled material. Background technique [0002] At present, pre-laid anti-adhesive self-adhesive membranes are widely used in most underground comprehensive pipe corridors and underground spaces in China. The construction method of this waterproof membrane is to lay the membrane on the base surface that has been constructed, and then carry out the main structural reinforcement. Binding and concrete pouring construction, the concrete structure can be closely bonded with the self-adhesive membrane, and it is mainly used for the construction of the structure bottom plate and the external wall of the bottom plate. Nowadays, masonry brick membranes are often used as the construction base for empty paving of the...

AI Technical Summary

Problems solved by technology

During the on-site construction, the pouring area of ​​the base cushion needs to include the width area of ​​the brick membrane, which wastes materials and requires a lot of labor; Long period, high project cost, etc.
