The invention discloses a foundation pit opening steel structure supporting device after excavation of a building foundation pit. The foundation pit opening steel structure supporting device comprises a combined supporting steel plate and a bottom plate, wherein a cross rod is fixedly connected to the bottom plate, the cross rod is hinged to the combined supporting steel plate, a first sliding groove and a second sliding groove are formed in the upper end of the bottom plate, a first guide rod is rotationally connected into the first sliding groove, a second guide rod is fixedly connected into the second sliding groove, a screw is arranged on the upper portion of the first guide rod, a driving block is slidably connected into the first sliding groove, and the screw is sleeved with the driving block which is in threaded connection with the driving block. According to the foundation pit opening steel structure supporting device, the supporting force of the combined supporting steel plate can be automatically increased, meanwhile, a worker can be reminded of the possibility that soil on the side wall of the foundation pit seeps water and becomes thin and collapses, so that the supporting work of the side wall of the foundation pit can be dealt with in time, the thin part of the soil on the side wall of the foundation pit can be pulled out, concrete can be added, and the stability of the side wall of the foundation pit is improved.
本发明公开了一种建筑基坑挖设后的基坑口钢结构支护装置，包括组合支护钢板和底板，所述底板上固定连接有横杆，所述横杆与组合支护钢板铰接连接，所述底板的上端设有第一滑动槽和第二滑动槽，所述第一滑动槽内转动连接有第一导向杆，所述第二滑动槽内固定连接有第二导向杆，所述第一导向杆上部分为螺杆，所述第一滑动槽内滑动连接有驱动块，所述驱动块套在螺杆的外部且与其螺纹连接。本发明不仅可以自动增加对组合支护钢板进行增加支撑力，同时，可以向工作人员提醒基坑侧壁泥土渗水变稀，存在坍塌的可能性，从而可以及时应对基坑侧壁的支护工作，且可以将基坑侧壁泥土变稀的部分抽出，可添加混凝土，以增加基坑侧壁的稳定性。
