Auxiliary equipment for automatically supporting and preventing collapse in construction process of building foundation pit
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.
本发明涉及建筑基坑技术领域，且公开了一种建筑基坑用建造过程中自动支护防止塌陷的辅助设备，包括主动轴，所述主动轴外部活动连接有传动座，所述传动座顶部活动连接有压缩弹簧，所述传动座左侧活动连接有推杆，所述推杆底部活动连接有挤压块，所述挤压块右侧活动连接有复位弹簧，所述复位弹簧右侧活动连接有转动轴，通过启动外部驱动源带动主动轴转动，从而拉伸压缩弹簧使其发生形变后带动传动座运动，传动座运动会带动支撑活塞运动挤压支撑气腔的内部空间，将支撑气腔内部的气体挤入支撑气囊内使其发生膨胀，从而对外部的土壤施加压力防止塌陷，从而达到了在挖掘基坑的同时对基坑进行支护防止其塌陷的效果。
