Underground space prefabricated integral structure and construction method thereof

Abstract

The invention relates to an underground space prefabricated integral structure and a construction method thereof. The structure comprises a U-shaped first-section open caisson, an H-shaped standard section arranged at the upper part of the U-shaped first-section open caisson, and an angle brace device arranged inside the U-shaped first-section open caisson. The U-shaped first-section open caissoncomprises a plurality of U-shaped open caisson elements, iron blade feet, twisted steel joint bars, and horizontal connecting devices arranged inside the U-shaped open caisson elements, and vertical connecting reinforcing steel bars arranged at the tops of the U-shaped open caisson elements. Connecting steel bar grouting holes are formed in the top faces of the U-shaped open caisson components. The H-shaped standard section comprises H-shaped composite wall plates fixed to the tops of the U-shaped open caisson elements, steel bar trusses arranged inside the H-shaped composite wall plates, fixing connecting parts and telescopic fixing devices arranged at the tops of the H-shaped composite wall plates; and shear keys and shear grooves are formed in the side wall faces of the two ends of theH-shaped composite wall plates respectively.

Description

technical field [0001] The invention relates to an underground space prefabricated assembly integral structure and a construction method thereof, which are applied in the technical field of underground space prefabricated assembly. Background technique [0002] The industrialization of construction is based on the prefabricated production of components and prefabricated construction as the main production methods, and is characterized by standardization of design, component parts, construction mechanization, and management informationization, and can integrate the entire construction industry such as design, production, and construction. Chain, a new production activity mode that realizes the sustainable and circular development of low-carbon, energy-saving, environmentally friendly construction products, and maximizes the life cycle value of construction products. Transitioning the traditional scattered and messy manual operation method to the industrial standardized produc...

AI Technical Summary

Problems solved by technology

The construction method is more environmentally friendly, and the construction site can realize the advantages of no dust, no waste, no construction measures and auxiliary materials, and no noise; Beams and other supporting reinforcement forms) or support first and then excavate (such as ground connection wall, cast-in-situ pile support form), the traditional technology has a long construction period and a large waste of materials. For example, the ground connection wall is used outside the underground space When there are internal bottom beams and interstory beam embedded parts in the wall, the concrete surface needs to be manually removed in the later stage, and even the embedded parts connected to the ground wall can not be used, and secondary drilling and rebar planting are required to complete the reinforced connection. The combination of "U" type caisson first section + "H" type laminated outer leaf wall panel + inner leaf cast-in-place concrete realizes the completion of beams, columns, floors, stairs, Standardized design, factory production and assembly construction of exterior walls and interior walls
