Background

The deep foundation pit refers to a project which has an excavation depth of more than 5 meters (including 5 meters), or has a depth of less than 5 meters, but has particularly complicated geological conditions, surrounding environments and underground pipelines. The foundation pit engineering mainly comprises foundation pit supporting system design and construction and earthwork excavation, and is a system engineering with strong comprehensiveness. It requires close cooperation between geotechnical engineering and structural engineering technicians. The foundation pit supporting system is a temporary structure and is not needed after the construction of underground engineering is finished.

Before construction, a support needs to be arranged in a foundation pit, and when a main body structure in the construction process conflicts with a support structure in the foundation pit, a support device needs to be detached. The existing support-dismantling reinforcing structure is generally provided with an inclined support between a bottom plate and a pre-dismantling inner support, the support-dismantling strength is low, the construction operation is complex, and the use is not safe enough.

Therefore, how to design a deep foundation pit inner support tear open and prop additional strengthening improves the efficiency of construction, reduces the potential safety hazard, becomes the problem that we will solve at present.
