Description

Technical Field

[0001] The utility model relates to the technical field of supporting devices, and more specifically to a supporting device for a foundation pit of a basement building. Background Art

[0002] When constructing underground buildings, it is necessary to first construct a foundation pit. The foundation pit is a soil pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be determined based on geological and hydrological data and the conditions of nearby buildings on site. Foundation pit support is a measure of support, reinforcement and protection for the side walls of the foundation pit and the surrounding environment to ensure the safety of underground structure construction and the surrounding environment of the foundation pit. In order to stabilize the soil slope of the foundation pit wall, a support device is generally set on the foundation pit support pit wall.

[0003] However, most of the existing foundation pit support devices have a relatively fixed structure and cannot be adjusted and installed according to the angle of the foundation pit wall. They have poor compatibility and are inconvenient to use. At the same time, the existing support uses materials such as steel sheet piles that can be turned over to consider turnover and economy. However, after the foundation pit is excavated, due to the inappropriate height and high flexibility of the steel sheet piles, the top of the foundation pit is more likely to have a large displacement, forming cracks on the top of the slope, which poses a strong safety hazard.

[0004] Therefore, we propose a basement construction foundation pit support device, which ensures the stability of the steel sheet pile support, solves the potential safety hazard problem and can be used in a revolving manner. Utility Model Content
