Abstract

The invention relates to the technical field of building foundation pits, and discloses auxiliary equipment for automatically supporting and preventing collapse in construction process of a building foundation pit. The auxiliary equipment comprises a driving shaft, a transmission seat is movably connected to the outer part of the driving shaft, a compression spring is movably connected to the top of the transmission seat, a push rod is movably connected to the left side of the transmission seat, an extrusion block is movably connected to the bottom of the push rod, a reset spring is movably connected to the right side of the extrusion block, and a rotating shaft is movably connected to the right side of the reset spring. An external driving source is started to drive the driving shaft to rotate, so that the compression spring is stretched to deform to drive the transmission seat to move, the transmission seat moves to drive a supporting piston to move to extrude the inner space of a supporting air cavity, air in the supporting air cavity is extruded into a supporting air bag to expand the supporting air bag, and therefore pressure is applied to external soil to prevent collapse, and the effect that the foundation pit is supported and prevented from collapsing while the foundation pit is excavated is achieved.

Description

technical field [0001] The invention relates to the technical field of building foundation pits, in particular to an auxiliary device for automatically supporting and preventing collapse during the construction process of building foundation pits. Background technique [0002] Existing buildings often need to excavate foundation pits during construction. In order to ensure the safety of the environment around the foundation pit and the stability of the foundation pit, the construction unit often adds certain support measures to the foundation pit. As the height of buildings continues to rise, the depth of excavated foundation pits is getting deeper and deeper, so the safety of foundation pits has attracted people's attention. [0003] Traditional foundation pit support devices are often installed after the foundation pit is excavated deeper, and in some areas with relatively soft soil, even if the excavation depth is shallow, there will be a risk of collapse. At the same tim...
