Mould support method of foundation pit basement haunch shearing wall

Abstract

The invention provides a mould support method of a foundation pit basement haunch shearing wall. The method includes the following steps: S1 integrally molding a basement base plate and an upper turning shearing wall arranged on the upper surface of the basement base plate in pouring mode and embedding reinforcing bar heads on the basement base plate; S2 building a brick base film on the outer side of the upper turning shearing wall and embedding a plurality of connection pieces in the brick base film; S4 welding a plurality of water stopping screws on the stretching ends of a plurality of connection pieces; S6 fixing a single side mould plate on the extending ends of the plurality of water stopping screws; and S8 building a plurality of inclined supports used for supporting the single side mould plate from the inside of the single side mould plate between the steel bar heads and the single side mould plate. Compared with the existing double side mould support method, the mould support method is simple to operate. Due to the fact that only the single side mould plate is supported on the inner side of the haunch shearing wall, the method is less is required construction space, low in construction cost, small in construction difficulty and short in construction period.

Description

technical field [0001] The invention relates to the field of building engineering construction, in particular to a formwork support method for adding axillary shear walls to basements of foundation pits. Background technique [0002] With the rapid development of modern urban construction, urban land resources are becoming more and more precious, and the available working surfaces for many construction projects are becoming less and less, especially for basement and axillary shear wall construction. At the same time, with the development of deep foundation pit support technology, the deep foundation pit support has changed from the original grading support to the more space-saving vertical support. When using the existing double-side formwork method, it is difficult to meet the construction technical requirements.
