Problems solved by technology
[0003] In related technologies, when deep foundation pits are excavated in areas with high groundwater levels, the soil aquifer is cut off, and groundwater will continue to infiltrate into the foundation pits. If drainage is not timely, it will easily cause quicksand, slope instability, or decrease the bearing capacity of the foundation. , and even cause the retaining wall of the foundation pit to collapse

The invention provides a foundation pit support frame, and relates to the technical field of buildings. The foundation pit support frame comprises a foundation pit bottom plate, support pieces, an enclosing purlin beam and water drainage pieces, wherein the foundation pit bottom plate is arranged at the bottom of a foundation pit; the support pieces are arranged in the foundation pit and support arock and soil layer, the support pieces are positioned in the circumferential direction of the foundation pit bottom plate and are cuboid-shaped and are configured to form cavities, and the bottom ends of the support pieces are lower than the foundation pit bottom plate; the enclosing purlin beam is used for supporting the two opposite support pieces, and the enclosing purlin beam is arranged atthe upper parts of the support pieces and is separately connected with the two opposite support pieces; and the water drainage pieces are arranged in the rock and soil layer, at least parts of the water drainage pieces extend into the cavities, and the water drainage pieces are used for draining water in the rock and soil layer into the cavities. The foundation pit support frame is reasonable in structure and good in drainage effect, and can effectively prevent the foundation pit retaining wall from collapsing.
Description
technical field [0001] The invention relates to the technical field of construction, in particular to a foundation pit support frame. Background technique [0002] The foundation pit support is to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit. The support, reinforcement and protection measures are adopted for the side wall of the foundation pit and the surrounding environment. The design requires that the foundation pit support, as a structural system, should meet the requirements of stability and deformation requirements. [0003] In related technologies, when deep foundation pits are excavated in areas with high groundwater levels, the soil aquifer is cut off, and groundwater will continue to infiltrate into the foundation pits. If drainage is not timely, it will easily cause quicksand, slope instability, or decrease the bearing capacity of the foundation. , and even cause the foundation pit retaining wal...
