A construction method for single side wall formwork support system

Abstract

The invention discloses a construction method for a unilateral wall formwork supporting system. The construction method comprises the following steps: A, supporting formworks are assembled; B, retaining wall steel bars are bound, all the supporting formworks are arranged at the periphery of a retaining wall in an adaptive manner, every two adjacent supporting formworks are connected for forming a supporting system part, and the supporting system parts are fixed relative to the ground; C, the retaining wall is subjected to concrete pouring and curing; and D, the supporting formworks are dismounted and the construction is completed. With the application of the construction method, the supporting formworks are used to support the retaining wall unilaterally without split screws, and no hole locations of the split screws are formed in the retaining wall constructed in such mode; the supporting formworks are high in structural strength, are spliced tightly and are good in pressure bearing capacity, so that the self-waterproof performance of structural concrete is improved effectively; and with the application of the construction method, a construction cycle is short, the influence of cross construction is little, the manpower is saved, the quantity of erected scaffolds is reduced, the construction efficiency is improved substantially and the cost is saved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method for a single-side wall formwork support system. Background technique [0002] Retaining walls are often used in underground structures of housing construction projects and subway projects. They play the dual role of structural load-bearing and blocking groundwater and soil. Traditional retaining walls usually use ordinary wooden formwork to close the formwork, and use double-drawn screws for formwork reinforcement. Retaining walls in subway construction and other projects have the characteristics of large structural thickness, high height, and high waterproof requirements. Using ordinary wooden formwork to construct retaining walls has problems such as large pressure bearing, large deformation, loose joints, and tensioning screws. Adverse effects on the self-waterproof performance of structural concrete. Contents of the invention [0003] The purpose ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the problems existing in the prior art that the retaining walls in projects such as subway construction have the characteristics of large structural thickness, high height, and high waterproof requirements, and ordinary wooden formwork is used to construct the retaining wall. Large size, large deformation, loose joints, and the above-mentioned disadvantages of the adverse effect of the pull screw on the self-waterproof performance of the structural concrete provide a construction method for the single-side wall formwork support system
