Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] see figure 2 As shown, a top view of the supporting structure of the foundation pit of the present invention is shown. The technical scheme of the present invention adopts a double-row pile structure arranged on the periphery of the foundation pit to support the foundation pit, so as to ensure that the structure of the foundation pit is stable and no collapse occurs. In addition, in order to enhance the strength of the support structure, the present invention also forms a reinforced soil body and an obliquely supported anchor rod assembly in the double-row piles. The reinforced soil body and the anchor rod assembly play an auxiliary role and help the double-row piles to resist the impact of the foundation pit. pressure to keep the foundation pit stable. The double-row piles, reinforced soil, and anchor components support each other an...

Abstract

The invention belongs to the field of construction, and particularly relates to a supporting structure and a supporting method for a foundation pit. The supporting structure for the foundation pit comprises double-row piles arranged on the periphery of the foundation pit, an anchor rod assembly and a reinforced soil body, a reinforced area is defined by the double-row piles, the double-row piles are anchored inside the ground of the foundation pit through the anchor rod assembly, and the reinforced soil body is formed in the reinforced area. The technical scheme that the reinforced soil body is arranged in the reinforced area inside the double-row piles is adopted, the integral supporting strength of the double-row piles is improved, the stability of the supporting structure for the foundation pit is guaranteed, the foundation pit is prevented from collapsing, and the problems such as potential safety hazards are solved.

Description

technical field [0001] The invention belongs to the field of construction, in particular to a support structure and a support method for a foundation pit. Background technique [0002] With the rapid development of urban rail transit construction across the country, more and more subway station foundation pit projects are constructed by open cut method. Most of the subway stations and entrances and exits are located in urban traffic arteries and prosperous areas, and the underground pipelines are dense and complicated. Pipeline relocation is often limited by factors such as space, pipeline function interruption, construction period, and construction cost. The foundation pit enclosure structure of the main body of the subway station and ancillary works can only be constructed near the block, and a new form of support structure has to be adopted. and construction methods, in order to minimize the impact of building envelope construction on underground pipelines and ensure the...
