Abstract

The invention discloses an adjacent foundation pit excavation supporting body and a supporting method. According to the adjacent foundation pit excavation supporting body, an existing supporting body is arranged in an existing foundation pit, the existing supporting body comprises an existing supporting pile, an existing anchoring part and an existing top beam, and the adjacent foundation pit excavation supporting body comprises a newly-added supporting pile, remained existing anchoring parts, connecting bars, and a newly-added crown beam. The adjacent foundation pit excavation supporting body is suitable for optimizing, reusing, transforming and reinforcing the existing supporting body in the excavation construction process of a new foundation pit close to the existing foundation pit, meets the requirements of new foundation pit supporting engineering, shortens the construction period and reduces the cost.

Description

technical field [0001] The invention belongs to the technical field of foundation pit support and underground engineering in the field of geotechnical engineering, and in particular relates to an adjacent foundation pit excavation support body and a support method. Background technique [0002] With the continuous advancement of urbanization, the pace is getting faster and faster, the density of urban buildings is increasing, and the construction land is becoming more and more scarce. The distance between adjacent buildings in planning and design is relatively close, and in order to meet the needs of urban construction, many projects The development progress is fast. For example, the existing foundation pit support has been constructed, the existing foundation pit has also been excavated, and a new building is newly planned. Since the new building is relatively close to the original building, it is difficult for the new foundation pit support. The difficulty is increased, b...
