Abstract

The invention provides an existing pipe gallery underground space and a supporting structure thereof and a construction method of the supporting structure. The method comprises the steps that soil around a pipe gallery is pre-reinforced, and supporting walls are arranged along the two sides of the pipe gallery; soil is excavated to the bottom level position of the pipe gallery, soil is drawn out below the pipe gallery in the length direction of the pipe gallery, so that multiple dispersed containing spaces are formed below the pipe gallery, and first support structures are arranged in the containing spaces; soil is excavated to the position below the pipe gallery, the first support structures are dismounted in sequence, meanwhile, plate-shaped second support structures are paved below thepipe gallery to replace the first support structures, and the second support structures are jointed to form a support plate to abut against the position below the pipe gallery; the underground space is excavated, and support piles are arranged according to the positions of structure piles in the design drawing of the newly-added underground space; and a bottom plate is poured at the bottom of theunderground space, and the bottom plate, the support piles and the supporting walls are connected into a whole. A construction foundation of a reverse building method is provided for excavation of theunderground space, and on the premise of guaranteeing that the existing pipe gallery is not influenced, the underground space is built.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to an underground space of an existing pipe gallery and its support structure, and a construction method for the support structure. The invention is mainly used in the case of adding an underground space under the existing comprehensive pipe gallery. Background technique [0002] With the further development of urbanization, the original underground pipelines, water lines, power lines, etc. need to find a better layout location, so the comprehensive pipe gallery came into being. Some cities face the problem of protecting the existing pipe gallery above the soil layer when constructing underground space. Therefore, how to better construct underground space under the soil layer while ensuring the existing pipe gallery is a new problem. The traditional protection method of pipe gallery adopts the suspension of Bailey beams, which will lead to an excessively large ground occupati...
