Abstract

The invention discloses an integrated foundation pit supporting structure and a construction method thereof. The integrated foundation pit supporting structure comprises a cement soil wall arranged atthe foundation pit supporting position, prefabricated parts integrally arranged in the cement soil wall and connecting pieces, wherein at least one connecting piece comprises an end inserting piece and a splicing piece; and grooves with the sinking direction perpendicular to the connecting direction of the two prefabricated parts are formed in the end inserting pieces and / or the splicing pieces.The advantages of the cement soil wall and the prefabricated parts are combined, the overall rigidity of the supporting structure is improved, the horizontal displacement of the supporting structurecan be effectively controlled, a good water stop effect is achieved, and a foundation pit supporting inner support and an anchor cable can be omitted. The integrated foundation pit supporting structure is suitable for projects needing to strictly control the horizontal displacement, and compared with a conventional supporting structure, the economic efficiency is good, the construction speed is higher, the work efficiency is higher, part of components can be recycled, and safety is better guaranteed.

Description

technical field [0001] The invention relates to the field of foundation pit support structures and construction thereof, in particular to an integrated foundation pit support structure and a construction method thereof. Background technique [0002] The foundation pit support structure is to ensure the safety of the underground construction and the surrounding environment of the foundation pit, and the support, reinforcement and protection structure adopted for the side wall of the foundation pit or the surrounding environment. [0003] The common method is to implant a single pile body in cement soil, and H-shaped steel can be built into the pile body as needed to improve the overall rigidity. For example, the patents with application numbers 201721092849.1 and 201721092865.0 are both based on supporting structures formed by implanting prefabricated components in cement-soil walls. [0004] However, such a setting method has weak horizontal rigidity and low reliability of ...
