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 supporting frame, and relates to the technical field of buildings. The foundation pit supporting frame comprises a foundation pit bottom plate, supporting members, a purlin beam and a drainage member; the foundation pit bottom plate is arranged at the bottom of a foundation pit; the supporting members are arranged in the foundation pit and used for supporting a rock-soil layer, the supporting members are located in the circumferential direction of the foundation pit bottom plate, the supporting members are in a cuboid shape and are provided with cavities, and the bottom ends of the supporting members are lower than the foundation pit bottom plate; the purlin beam is used for supporting the two opposite supporting members, and the purlin beam is arranged on the upper portions of the supporting members and connected to the two opposite supporting members correspondingly; and the drainage member is arranged in the rock-soil layer, at least part of the drainage member extends into the cavity, and the drainage member is used for draining water in the rock-soil layer into the cavity. The foundation pit supporting frame is reasonable in structure, good in drainage effect and capable of effectively preventing 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...
