Problems solved by technology

[0009] 1) Although the above scheme proposes the support technology and self-balancing method of the underwater foundation pit, it cannot balance the earth pressure by adjusting the support length of the support system after the deformation of the foundation pit
[0010] 2) The above technical solution adopts rigid support technology, which cannot realize flexible adjustment

Embodiment

[0065] As a preferred implementation mode, this embodiment takes the foundation pit as a standard cuboid structure as an example, combining Figure 1-8 As shown, a foundation pit support balance system includes several straight support parts 1, corner support parts 2, lattice columns 3, connectors 4, and multi-layer beam structures 5, and the beam structures 5 of the same layer are connected end to end to form a rectangular structure and is arranged on the side wall of the foundation pit 6, the two ends of the straight support member 1 are abutted on two opposing beam structures 5, and the plurality of straight support members 1 are equidistantly arrayed on the beam structure 5 on the same floor of the foundation pit 6 Above, the corner supporting parts 2 are installed at each corner of the foundation pit 6 and are located at the inner corners of the foundation pit 6. One end of the lattice column 3 abuts against the pile foundation 7 arranged at the bottom of the foundation pi...

Abstract

The invention relates to a foundation pit support balance system. The foundation pit support balance system comprises straight supporting parts, corner supporting parts, lattice columns, connecting pieces and beam structures, wherein the beam structures are arranged on the side wall of a foundation pit in an end-to-end connection mode, the two ends of the straight supporting parts abut against thebeam structures in two opposite directions, the straight supporting parts are equidistantly arrayed on the beam structures in the same layer of the foundation pit, the corner supporting parts are arranged at corners of the foundation pit and located at the inner corners in the foundation pit, one ends of the lattice columns abut against a pile foundation at the bottom of the foundation pit, the other ends of the lattice columns abut against the topmost straight supporting parts, one sides of the connecting pieces are connected with the lattice columns, the other ends of the connecting piecesare connected with the straight supporting parts, and the connecting pieces are connected with all the straight supporting parts in the same plane. Through the scheme, the method for adjusting the supporting length of the supporting system after the foundation pit is deformed is realized, and the technology for flexibly adjusting the supporting system is realized.

Description

technical field [0001] The invention relates to the technical field of foundation pit engineering support construction, in particular to the field of self-balancing equipment for foundation pit support and support technology, in particular to a foundation pit support balance system and an installation method. Background technique [0002] Since the 21st century, the demand and development of underground space have been increasing. [0003] At present, people's development of underground space is mainly to build underground tunnels, basements, underground commercial complexes, etc., and the current common technical process for building basements is to first construct the underground maintenance mechanism, and then carry out foundation pit excavation. During the process, due to the need to balance the external forces such as soil pressure and water pressure in the soil, it is necessary to establish a support system to balance the above forces, thereby preventing the foundation...
