Anti-collapse foundation pit supporting structure
The invention belongs to the technical field of foundation pit protection, and particularly relates to an anti-collapse foundation pit supporting structure which comprises a base, rotating screws are arranged on the periphery of the base, a telescopic arm is rotationally connected to the end, close to the rotating screws, of the base, an abutting baffle is rotationally connected to one end of the telescopic arm, and the rotating screws drive the telescopic arm to stretch out and draw back. A withdrawing device is arranged in the abutting baffle. The withdrawing device comprises a movable baffle plate which is arranged in the abutting baffle plate and slides in the movable baffle plate; and one end of the connecting plate is fixedly connected with a movable baffle, and counter-acting force can be formed between the movable baffle and the abutting baffle through the connecting plate. By means of the withdrawing device and the rotating power gear, counter-acting force is formed between the movable baffle and the abutting baffle, the abutting baffle sinking into soil on the side wall of the foundation pit can be taken out, the needed acting force is small, the withdrawing mode is more convenient, and therefore follow-up withdrawing work is facilitated.
本发明属于基坑防护技术领域，具体的说是一种防坍塌的基坑支护结构，包括基座，基座的四周均设有转动螺杆，基座靠近转动螺杆的一端转动连接有伸缩臂，伸缩臂的一端转动连接有抵接挡板，且转动螺杆带动伸缩臂进行伸缩，抵接挡板的内部设有收回装置；收回装置包括：活动挡板，活动挡板设在抵接挡板的内部，且在活动挡板的内部滑动；连接板，连接板的一端固定连接有活动挡板，且活动挡板与抵接挡板之间通过连接板可形成反作用力。通过收回装置，转动动力齿轮，使活动挡板与抵接挡板之间形成反作用力，可以将陷入基坑侧壁泥土中的抵接挡板取出，且所需的作用力较小，收回的方式也更加方便，从而方便后续的收回工作。
