Excavation supporting structure for excavation of foundation pit above tunnel
The invention provides an excavation supporting structure for excavation of a foundation pit above a tunnel, which structurally comprises a positioning seat, a vertical body, a connecting wall and a supporting plate, the interior of the positioning seat is fixedly connected with the lower end of the vertical body, and the vertical body is connected with the edge of the connecting wall; the two sides of the edge of the supporting plate are welded and connected with the lower layer of the connecting wall and connected with the vertical body through the connecting wall. After the movable control piece is further improved, the outer layer of the vertical rotating rod of the movable control piece and the areas of the driving block and the adaptive layer can be covered through the dustproof shell of the parallel block, accumulation and jamming caused by dust invasion are prevented, then the height adjusting body can be adjusted according to control of the vertical rotating rod on the transverse rotating rod, and the height adjusting effect is improved. The height adjusting body can be straightened or bent to adjust the height of the supporting plate, so that the use convenience of the supporting structure is improved, and the supporting strength of the supporting structure can be further enhanced under the clamping of the hardness of the vertical rotating rod and the transverse rotating rod of the height adjusting body.
本发明提供一种隧道上方基坑开挖的开挖支护结构，其结构包括：定位座、垂直体、衔接壁、支护板，定位座内部与垂直体下端进行固定连接，垂直化体与衔接壁边缘相连接，支护板边缘两侧与衔接壁下层进行焊接衔接并通过衔接壁与垂直体相连接；本发明由活动控制件进一步改进后，通过平行块的防尘壳能将活动控制件的垂直转杆外层以及驱动块、适配层区域进行覆盖，防止粉尘入侵造成的堆积卡死，然后依据垂直转杆对横向转杆的控制能将高度调节体的进行调整，使得高度调节体将进行立直或弯曲来达到对支护板的高度进行调节，进而提高支护结构的使用便利性以及通过高度调节体的垂直、横向转杆硬度加持下能进一步强化支护结构的支护强度。
