The invention relates to the technical field of foundation pit supporting, and discloses a foundation pit supporting device and a foundation pit supporting method.The foundation pit supporting device comprises a supporting plate, and the two ends of the side face of the supporting plate are each provided with a first supporting assembly and a second supporting assembly; the first supporting assembly comprises a strip-shaped inserting block which is horizontally arranged on the side face of the supporting plate, the other side of the supporting plate abuts against a limiting plate, the tail end of the strip-shaped inserting block penetrates through the supporting plate and is fixedly installed at the center of the side face of the limiting plate, and a cone is fixedly installed at the top end of the strip-shaped inserting block. A reinforcing assembly used for reinforcing the stability of the strip-shaped inserting block is arranged in the strip-shaped inserting block. According to the device, the limiting nails can synchronously move and rotate, so that the limiting nails can more smoothly enter soil after extending out of the strip-shaped inserting blocks, stable limiting of the strip-shaped inserting blocks is achieved, and the supporting safety of the supporting plate is further guaranteed.

本发明涉及基坑支护技术领域，公开了一种基坑支护装置及基坑支护方法，包括支护板，支护板侧面两端均设有第一支护组件和第二支护组件；第一支护组件包括：条形插块，条形插块水平设置于支护板侧面，且支护板另一侧抵接有限位板，条形插块末端穿过支护板并固定安装于限位板侧面中心处，且条形插块顶端固定安装有椎体，条形插块内部设有用于加固条形插块稳定性的加固组件。本发明能够使限位钉同步的移动和转动，从而可使限位钉在伸出条形插块后，并且伸出条形插块后可更加顺利的进入土壤内部，实现条形插块的稳定限位，进一步的保证了支护板的支护安全性。
