Foundation pit supporting structure and pit wall collapse prevention construction method
The invention discloses a foundation pit supporting structure and a pit wall collapse prevention construction method. The foundation pit supporting structure comprises a supporting bearing seat; a driving worm gear is rotationally arranged at the center position of a driving cavity in the support bearing seat through a bearing; a protective top plate is arranged on the top surface of the support bearing seat; wherein the outer sides of the top surfaces of the supporting bearing seats are fixedly connected to the bottom ends of the lifting cylinder seats at equal intervals, and the interiors of the lifting cylinder seats which are arranged at equal intervals are slidably connected to the bottom ends of the lifting lining plates; the center position of the top face of the driving support is fixedly connected to the bottom end of the lifting sleeve. According to the foundation pit supporting structure and the pit wall anti-collapse construction method, falling soil in foundation pits with different depths is shielded through the supporting bearing seat and the protection top plate which are arranged in the foundation pit, and the inner wall of the foundation pit can be in contact to the maximum extent through the supporting main lining plate moving towards the outer side and the extensible supporting auxiliary lining plate; and the supporting effectiveness and the supporting stability are improved.
发明公开了一种基坑支护结构及坑壁防塌陷施工方法，包括支护承载座；所述支护承载座内部驱动腔体的中心位置处通过轴承转动设置有驱动蜗轮；还包括：所述支护承载座的顶面设置有防护顶板；其中，支护承载座的顶面外侧等距离固定连接于举升筒座的底端，且等距离设置的举升筒座的内部滑动连接于举升衬板的底端；其中，驱动支架的顶面中心位置处固定连接于升降套筒的底端。该基坑支护结构及坑壁防塌陷施工方法，通过置于基坑中的支护承载座以及防护顶板针对不同深度的基坑内部落土进行遮挡，并通过向外侧移动的支护主衬板以及可延展的支护副衬板，进而能够最大程度的接触基坑的内壁，提升支护的有效性以及支护的稳定性。
