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

Abstract

The invention provides a foundation pit support frame, which relates to the technical field of construction. The support frame of the foundation pit includes: a bottom plate of the foundation pit, which is arranged at the bottom of the foundation pit; a support member, which is arranged in the foundation pit and supports the rock and soil layer, and the support member is located in the circumferential direction of the bottom plate of the foundation pit, The support is in the shape of a cuboid and is configured to have a cavity, and the bottom end of the support is lower than the bottom plate of the foundation pit; the purlin beam is used to support two opposite supports, and the purlin beam is arranged on the support The upper part of the member is connected with two opposite support members respectively; and the drainage member is arranged in the rock and soil layer and at least part of the drainage member extends into the cavity, and the drainage member is used to drain the water in the rock and soil layer into the cavity. The supporting frame of the foundation pit has a reasonable structure and good drainage effect, and can effectively avoid the collapse of the retaining wall of the foundation pit.

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...
