Description

Technical Field

[0001] The utility model relates to the technical field of subway construction assistance, in particular to a supporting device for subway construction. Background Art

[0002] Subway is a fast, high-capacity, electric-powered rail transit system built in cities. Trains run on fully enclosed lines. Lines in the central urban area are basically located in underground tunnels, while lines outside the central urban area are generally located on viaducts or on the ground. Subway is a high-density, high-capacity urban rail transit system that covers all kinds of underground and above-ground road rights in urban areas.

[0003] At present, during the construction of subway buildings, it is necessary to fix and support the baffles in the foundation pit. Most of the existing support devices directly support vertically through the support frame. Since they cannot support some curved foundation pits, the support of the subway construction is affected.
