Stratum monitoring device for tunnel and deep foundation pit construction

ZHANG YANGSONG / ZHU HUIYU

The invention discloses a stratum monitoring device for tunnel and deep foundation pit construction. The device comprises a base plate, wherein a threaded sleeve is fixedly embedded into the upper endof the base plate; the interior of the threaded sleeve is in threaded connection with a screw; one end of the screw is rotatably connected to a supporting plate; a first driving motor is fixedly arranged at the upper end of the supporting plate through a first fixing frame; one end of an output shaft of the first driving motor is fixedly connected to one end of the screw through a coupling; the other end of the screw is rotatably connected to a fixed block; a wireless monitoring probe is arranged at the lower end of the fixed block; a telescopic rod is arranged at the upper end of the base plate; and one end of the telescopic rod is fixedly welded to the lower end of the supporting plate. According to the device, the screw is driven to rotate through the first driving motor, due to the fact that the screw is in threaded connection with the threaded sleeve, the screw can ascend and descend by rotation of the screw, so that the wireless monitoring probe at the other end of the screw isdriven to ascend and descend, and thus different depths of a deep foundation pit can be monitored as needed.

本发明公开了一种隧道深基坑施工的地层监测装置，包括基板，所述基板的上端嵌装固定有螺纹套管，所述螺纹套管的内部螺纹连接有螺杆，所述螺杆的一端转动连接有支撑板，所述支撑板的上端通过第一固定架固定安装有第一驱动电机，所述第一驱动电机输出轴的一端通过联轴器固定连接于螺杆的一端，所述螺杆的另一端转动连接有固定块，所述固定块的下端设置有无线监测探头，所述基板的上端设置有伸缩杆，所述伸缩杆的一端固定焊接于支撑板的下端。本发明能通过第一驱动电机带动螺杆转动，由于螺杆与螺纹套管之间螺纹连接，螺杆的转动能使螺杆自身升降，从而带动螺杆另一端的无线监测探头升降，能根据需要对深基坑不同深度进行监测。
