Temporary supporting device for underground foundation pit construction
The invention belongs to the technical field of foundation pit supports, and discloses a temporary supporting device for underground foundation pit construction, which comprises a plurality of supporting rings, the supporting rings are arranged in parallel at equal intervals, the central axes of the supporting rings are overlapped, and a plurality of groups of limiting mechanisms are arranged on the circumference of the middle part of every two adjacent supporting rings at equal intervals. The uppermost supporting ring of the supporting device is arranged at the top end of the foundation pit, and when the first supporting plate is extruded by the inner wall of the foundation pit, the first supporting plate and the second supporting plate reversely push the supporting ring to generate upward moving force through the sliding rail, the first bent lever, the rotating seat and the second bent lever; the supporting ring drives the sliding sleeve fixedly connected with the supporting ring to tend to move upwards along the sliding rod, but the sliding sleeve is limited to slide upwards along the sliding rod due to the fact that the plane of the bottom end of the clamping hole, close to one side of the supporting ring, of the sliding sleeve makes contact with the plane of the bottom end of the clamping block, and therefore the supporting ring can only move downwards and cannot move upwards. And therefore, the whole inner wall of the foundation pit can be quickly supported.
本发明属于基坑支架技术领域，且公开了一种地下基坑建设用临时支护装置，包括多个支环，多个支环等距平行排列，多个支环的中轴线重合，相邻两个支环的中部圆周等距设有多组限位机构。本发明通过将支护装置最上方的支环设置在基坑的顶端，当第一支撑板受到基坑内壁挤压，第一支撑板和第二支撑板反向通过滑轨、第一曲杆、转座和第二曲杆推动支环产生向上移动的力，支环带动与其固定连接的滑套产生沿着滑杆向上移动的趋势，但是由于滑套靠近支环一侧的卡孔底端平面与卡块底端的平面接触，限制滑套沿着滑杆向上滑动，从而实现支环只能向下移动，不能向上移动，进而实现了快速对基坑的整个内壁进行支撑。
