The invention provides a foundation pit supporting device and a using method thereof. The foundation pit supporting device comprises vertical piles, surrounding purlins and a supporting structure. A plurality of vertical piles which are vertically arranged surround the pit wall of the foundation pit side by side; a bracket is installed on the wall face, away from the pit wall, of the vertical pile, the enclosing purlin is transversely erected on the top of the bracket, and the ends of the enclosing purlin are connected and abut against the wall face of the vertical pile. The support structure is used for supporting two opposite enclosing purlins at the same height; bearing structures are arranged on the two groups of opposite enclosing purlins located on the two pit walls of the foundation pit, and the bearing structures can move along the enclosing purlins after being adjusted; the bearing structure is used for bearing the frame supporting structure before outward ejection; the bearing structure can be separated from the in-place mounting and supporting structure through adjustment; assembly and building can be facilitated, the construction operation efficiency is improved, the suspended hanging time is shortened, and potential safety hazards are reduced.

本发明提供了一种基坑支护装置及其使用方法，包括立桩、围檩、架撑结构；多条竖向设置的立桩并排围挡在基坑的坑壁处；立桩远离坑壁的壁面上安装有托架，围檩横向架设在托架的顶部、并端部相连，抵持在立桩的壁面上；架撑结构用于对处于同一高度的相对两围檩之间进行支撑；处于基坑两坑壁的相对的两组围檩上均设有承托结构，承托结构经调节可沿围檩移动；承托结构用于对朝外顶出前的架撑结构进行承托；承托结构经调节可从安装到位的架撑结构处脱离；可便于装配搭建，提高施工作业效率，减小悬空吊挂时长，降低安全隐患。
