Problems solved by technology

[0003] Most of the traditional support structures are traditional support beam structures. The traditional support beam structure occupies a large construction area during the construction process, and the construction convenience of the structure in the foundation pit is poor. At the same time, the installation, disassembly and The excavation period of foundation pit earthwork and other construction is long, and the construction cost is high

Abstract

The invention provides a prefabricated support structure construction process based on prestressed fish-belly beam support technology, comprising the steps of selecting support structural members, constructing an enclosure wall, constructing column members, constructing triangular carrier members, mounting round purlin members, mounting carriers and support beam members, mounting angle brace members, mounting fish-belly members, mounting fish-belly beam members and applying prestress. The prestressed fish-belly beam support technology is used herein to manufacture the prefabricated support structure; rigidity and stability of the whole prefabricated support structure can be improved; construction site space can be enlarged; other production in a foundation pit is facilitated; the process herein also has the advantages of short construction period. Energy consumption is greatly reduced; pretreatment of the triangular carrier members helps improve post-mounting stability of triangular carriers; a better positioning reference environment is provided for the round purlin mounting in subsequent steps; therefore, mounting precision and structural stability of the whole prefabricated support structure can be improved.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a construction process of an assembled support structure based on a prestressed fish-belly beam support technology. Background technique [0002] Foundation pit support is an engineering construction method that adopts support, reinforcement and protection measures for the side wall of the foundation pit and the surrounding environment to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit. The prefabricated support structure is based on formed prefabricated components, which are assembled on site through various technical means to form a support structure. At present, the more mature prefabricated support structures on the market include: prefabricated piles, prefabricated underground diaphragm wall structures, Prestressed fish-belly beam support structure, tool-type combined internal support, etc. Among them, ...
