Prefabricated construction method for straight wall of pit

Abstract

The invention relates to a prefabricated construction method for a straight wall of a pit. The prefabricated construction method can avoid the phenomena of formwork expansion and material waste in the prior art by decomposing the straight wall of the pit into parts and installing the parts of a prefabricated wall plate from zero to whole in a blocking manner during construction, thereby being beneficial to reducing the cost, concrete prefabricated wallboards are prefabricated on site and can be stored in advance, the construction efficiency is favorably improved, the construction period is shortened, a traditional formwork is replaced, the prefabricated wallboard formwork is light in weight, good in compactness, convenient to connect and easy in node treatment, and is beneficial to forming a complete wall body and pouring the concrete, so that the prefabricated wallboard formwork is not easy to loosen and crack, the prefabricated concrete wallboards form a complete formwork system, the requirements for stability and strength of the overall structure of the wallboards are met by adjusting the connection relation among the wallboards, the upper prefabricated wallboards and the lower prefabricated wallboards are more accurately installed together, deviation is not likely to happen, and a foundation is laid for subsequent straight wall construction.

Description

technical field [0001] The invention relates to the technical field of cellar construction, in particular to an assembled construction method for straight walls of cellars. Background technique [0002] After the construction of the cellar in the winery, due to the technical requirements, it is common to use cast-in-situ concrete vertical walls as the protective layer around the cellar. In recent years, a common problem has been found in the construction of the vertical wall of the cellar. Limited, or partially affected by the foundation of the factory building, the construction of the cast-in-place concrete straight wall formwork project is difficult, the formwork explodes when pouring concrete, and the flatness of the straight wall surface is poor, which in turn leads to poor construction foundations such as the quality control of the straight wall, and at the same time Due to the requirements of concrete technical performance, the formwork cannot be removed in a short per...
