Novel pipe curtain-box culvert integrated tunnel structure and construction method

Abstract

The invention provides a novel pipe curtain-box culvert integrated tunnel structure and a construction method, and belongs to the field of tunnel structures. A rectangular steel pipe curtain is jacked and then connected through an integrated locking opening, high-fluidity concrete is poured into the rectangular steel pipe curtain, and finally an overall stable structure is formed. According to the novel pipe curtain-box culvert integrated tunnel structure and the construction method, the novel pipe curtain-box culvert integrated tunnel structure is flexible in section form, good in environmental influence control, can be applied in shallow burying or even ultra-shallow burying, high in construction mechanization level, has great advantages when being applied to short-distance crossing projects, and good in economical efficiency.

Description

technical field [0001] The invention belongs to the field of tunnel structures. Background technique [0002] At present, the commonly used construction methods of tunnels include: open cut method, drill and blast method, shield method, pipe jacking method, pipe curtain box culvert method, etc. Among them, the open cut method and drilling and blasting method are limited by the site and environmental conditions; the tunnel section of the shield tunneling method and the pipe jacking method is small and cannot meet the requirements of large traffic flow; It controls the environmental impact and has the advantages of large tunnel section size, but the construction time is long, and the pipe curtain has little effect on controlling the environment in the normal use stage of the structure, and the pipe curtain cannot be recycled, resulting in high construction costs. This patent intends to use a small rectangular pipe jacking machine to jack steel pipes into the soil, connect adj...
