Safety device for deep foundation pit in soft soil area of liquefied sand layer
The invention provides a safety device for a deep foundation pit in a soft soil area of a liquefied sand layer. Comprising a base, a baffle arranged on the base, a supporting structure arranged on the base and used for supporting the baffle and a buffer plate installed on the outer side of the baffle in a sliding mode, and a collapse early warning mechanism is arranged on the inner side of the baffle; the collapse early warning mechanism comprises a fixing plate fixed to the inner surface of the baffle, a mounting frame arranged on the fixing plate, a buzzer fixed to the mounting frame, a pressing switch electrically connected with the buzzer and a sliding rod fixedly connected with the buffer plate. According to the deep foundation pit supporting structure, the collapse early warning mechanism is arranged on the inner side of the baffle of an existing deep foundation pit supporting structure, so that when collapse occurs, the buffer plate slides to drive the sliding rod to slide, the sliding rod extrudes the pressing switch when sliding, a circuit of the buzzer is switched on, buzzing is conducted, and a worker can be warned in time.
本发明提供一种液化砂层软土区深基坑安全装置。包括底座、设置在所述底座上的挡板、设置在所述底座上用于对挡板进行支撑的支撑结构以及滑动安装在所述挡板外侧的缓冲板，所述挡板的内侧设有塌陷预警机构，所述塌陷预警机构包括固定在所述挡板内表面的固定板、设置在所述固定板上的安装架、固定在所述安装架上的蜂鸣器、与所述蜂鸣器电连接的按压开关以及与所述缓冲板固定连接的滑杆，本发明在现有的深基坑支护结构的挡板内侧设置塌陷预警机构，使得在发生塌陷时，缓冲板滑动带动滑杆滑动，滑杆滑动时挤压按压开关，使得蜂鸣器的电路接通并发出蜂鸣，能够及时对工作人员进行警示。
