Single-side support-formwork system backing on brick mixing retaining wall and construction method

Abstract

The invention discloses a single-side support-formwork system backing on a brick mixing retaining wall. The single-side support-formwork system backing on the brick mixing retaining wall comprises the brick mixing retaining wall and a timber formwork, wherein a space for pouring concrete is defined by the brick mixing retaining wall and the timber formwork. A water stopping positioning screw rod is pre-buried in the brick mixing retaining wall, one end, stretching out of the brick mixing retaining wall, of the water stopping positioning screw rod penetrates through the timber formwork, and the oppositely-pilling force capable of bearing the concrete pouring side pressure is generated on the brick mixing retaining wall and the timber formwork, one side, backing to the brick mixing retaining wall, of the timber formwork is provided with an inner ridge and an outer ridge, the inner ridge and the outer ridge are arranged in a mutually-perpendicular mode, and the water stopping positioning screw rod penetrates through the outer ridge and is fixed with the outer ridge. The single-side support-formwork system is simple in structure, convenient to operate and high in reliability degree, when the retaining wall is constructed, a stress supporting part of the support-formwork system is completed at the same time, the large amount of steel material cost and the labor cost of a conventional single-side support formwork are saved, and the construction efficiency is further improved. A construction method suitable for the single-side support formwork backing on the brick mixing retaining wall is provided.

Description

technical field [0001] The invention relates to the technical field of pouring concrete walls in building construction, in particular to a single-side formwork system and a construction method with a backing brick-concrete retaining wall. Background technique [0002] In the construction of underground concrete wall structures in construction projects, pits in pits or basements with height differences are often encountered. Due to limited conditions, it is necessary to use brick-concrete walls to retain soil on one side of the concrete wall, and then back against the brick-concrete The construction of the concrete wall structure is carried out on the wall surface, which will inevitably cause the concrete wall to adopt the method of single-side formwork for construction. The reliability of the single-side formwork is directly related to the quality of the construction of the concrete wall structure. [0003] At present, the construction of unilateral support formwork for...

Problems solved by technology

This system can only be applied to the formwork system of relatively short concrete walls, but in the case of high concrete walls, the connecting parts and diagonal braces of the triangular one-sided support often cannot withstand the stress during the concrete pouring process. The generated side pressure causes damage and instability, and the production and installation of this single-side formwork system requires a large labor and material cost, which is not economical
