Description

Technical Field

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

[0002] Foundation pit refers to the space below the ground excavated for the construction of the foundation and basement of a building (including structures). Before excavation, the excavation plan should be determined based on the geological survey data and the situation of nearby buildings on site, and waterproofing and drainage work should be done. If the excavation is not deep, the slope can be used to stabilize the slope, and the slope size is determined according to relevant construction regulations. For deep excavations and nearby buildings, foundation pit wall support methods and shotcrete wall protection methods can be used. Large foundation pits can even use underground continuous walls and column-type bored pile interlocking methods to prevent the outer soil layer from collapsing. If there is no impact on nearby buildings, the well point method can be used to lower the groundwater level and use slope open excavation. In cold areas, natural freezing methods can be used for excavation, etc.

[0003] The foundation pit support structure refers to the reasonable, effective and economical technical measures adopted to ensure the safety and progress of foundation pit excavation construction, according to the different depths of the foundation pit, soil characteristics and surrounding environment. It is a general term for various components and accessories used to support the surrounding areas of the foundation pit.

[0004] When the existing support structure is in use, the support plate is generally placed on the inner wall of the foundation pit, and then one end of the support rod is pressed against the side wall of the support plate, and the other end of the support rod is pressed against the bottom of the foundation pit, so that the support plate, the support rod and the bottom of the foundation pit form a triangle. One end of the support rod is supported by the bottom of the foundation pit, so that the other end of the support rod provides support force for the support plate, so that the support plate can apply force to the inner wall of the foundation pit, making the inner wall of the foundation pit less likely to collapse. However, when this type of support structure is actually used, the bottom end of the support rod and the bottom wall of the foundation pit are prone to slipping, which makes the support force of the support rod on the support plate insufficient, affecting the support effect of the foundation pit.

[0005] Therefore, it is necessary to provide a new foundation pit supporting structure to solve the above-mentioned technical problems. Utility Model Content
