The measuring rod 8 can perform vertical sliding displacement along the measuring unit 7. On one side wall of the measuring rod 8, there is a vertical scale groove 802. The bottom end of the measuring rod 8 is rotatably connected to a bottom-attaching mechanism 9. The bottom-attaching mechanism 9 can ensure the accuracy of the measurement data of the measuring rod 8 for the slope of the river channel foundation pit;

[0033] The measuring unit 7 includes a bearing platform 702. On the upper end of the bearing platform 702, there are a transverse observation camera 703 and a vertical observation camera 704 fixedly installed. The transverse measurement camera is oriented towards the transverse scale groove 604, and the vertical observation camera 704 is oriented towards the vertical scale groove 802. The transverse observation camera 703 can perform real-time observation on the transverse scale groove 604, and the vertical observation camera 704 can perform real-time observation on the vertical scale groove 802.

[0034] As Figures 1 - 3 shown, at the four corners of the lower end of the base 2, there are universal wheels fixedly installed, enabling the base 2 to perform displacement adjustment; on the upper end of the base 2, on one side of the support 3, there is a counterweight groove 4.
