Mobile shelter suitable for subway station construction and construction method

Abstract

The invention discloses a mobile shelter suitable for subway station construction and a construction method. The mobile shelter comprises a plurality of shelter units arranged above a foundation pit, guiding rails are arranged on the ground on the two sides of the foundation pit, the length of each guiding rail is larger than the sum of the widths of all the shelter units by at least the width of one shelter unit, each shelter unit comprises a truss structure, side surface supports arranged on the two sides of the truss structure, a ceiling clad material layer arranged above the truss structure and a motor, sliding wheels matched with the guiding rails are arranged at the lower ends of the side surface supports, each motor can drive the corresponding side surface support to move along the corresponding guiding rail, and opening or covering of different segments of the foundation pit is achieved by the shelter units moving along the guiding rails. According to the mobile shelter, the truss structures are adopted, compared with existing folding shelters, the mobile shelter has the advantages that the stiffness and the reliability are higher, and the span of the shelter can be increased; negative impacts on a surrounding environment in noise, dust and illumination are low, so that the idea of green construction is conformed.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a mobile shelter suitable for subway station construction and a construction method. Background technique [0002] At present, many cities carry out subway planning and need to construct a large number of subway stations. On the one hand, the excavation construction of subway stations is often restricted by bad weather such as rain and high temperature, and it is difficult to effectively guarantee the construction period and quality. On the other hand, in recent years, residents and merchants around the subway construction site have increasingly higher requirements for construction environmental protection. Therefore, it is of great significance to implement closed construction in subway stations. [0003] The existing subway closed construction utilizes a fixed factory building, that is, a large factory building covering the entire excavation construction area is built on ...

Problems solved by technology

However, this patent adopts a folding canopy, which has a small structural rigidity, which limits the span of the canopy

Moreover, this patent requires manual folding, which is time-consuming and laborious, and the construction efficiency is low

In addition, the patented folding canopy needs to be folded, and the roof covering material layer adopts an opaque flexible material layer, which has poor lighting performance, which is not conducive to construction, and consumes a lot of lighting energy.
