Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit support, in particular to a deep foundation pit support structure. Background Art

[0002] A deep foundation pit refers to an excavation depth of more than 5 meters (including 5 meters) or a basement with more than three floors (including three floors), or a project with a depth of less than 5 meters but particularly complex geological conditions, surrounding environment and underground pipelines.

[0003] However, in the prior art, the support device of the foundation pit is generally composed of multiple groups of baffle plates. Although such a support device can better fit the foundation pit and is convenient for installation and disassembly, there is a lack of connecting and limiting components between the baffle plates, resulting in weak connection between the baffle plates, low overall integrity of the device, and uneven support force. For this reason, we propose a deep foundation pit support structure. Utility Model Content
