[0001] The utility model relates to the technical field of tunnel construction, in particular to a tunnel deformation monitoring and measuring point arrangement device. Background Art

[0002] Monitoring and measurement, as the core of the New Austrian Tunnel Construction Method (NATM) tunnel construction, is an important means to monitor the stability of the tunnel surrounding rock in real time and to verify the rationality of technical measures such as construction methods and design support. Tunnel deformation measurement is the main content of tunnel construction monitoring. With the development of modern measurement technology, total stations have been widely used in tunnel deformation monitoring. In the actual monitoring process, it is usually necessary to install multiple deformation measurement points on the tunnel wall to monitor the deformation of the tunnel.

[0003] The existing tunnel deformation monitoring and measurement point layout device has a cumbersome installation method and is not convenient for long-term use. At the same time, some angles are mostly fixed and do not have the function of angle adjustment. It cannot be adjusted according to the actual use situation on site, and its practicality is poor. Therefore, we propose a tunnel deformation monitoring and measurement point layout device. Utility Model Content

[0011] Furthermore, the first connecting rod and the sleeve are telescopically connected, and the first connecting rod and the second connecting rod are matched with each other.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the rod body is fixed to the tunnel wall by the expansion screws at the bottom end of the first mounting frame, and then is hung by a hook at one end of the frame. If the angle needs to be adjusted, the tightness is adjusted by the second fasteners on the end faces of both sides of the sleeve, so that the built-in connecting rod can be extended and retracted to complete the tilting. If the frame is horizontal, it is convenient for the monitoring frame and the frame plate to move horizontally, thereby improving the stability of the measuring point.

[0013] The rod body and the first mounting frame are integrated and fixed to the tunnel wall by the expansion screws at the bottom of the first mounting frame. At the same time, the second mounting frame at the bottom is installed in the same way as the first mounting frame. Since the monitoring frame is installed on the frame plate, it is then embedded in the frame and hung on the rod body according to the hook at one end of the frame. The other end is supported by the connecting rod and the sleeve, making the whole triangular shape, thereby improving the stability of the measuring point, and the hook at one end is also convenient for disassembly or angle adjustment and rotation.

[0014] The frame plate is used to cooperate with the frame, and the interior of the frame is provided with sliding grooves matching the limit blocks at both ends of the frame plate, so as to facilitate the sliding of the frame plate inside the frame and the horizontal movement of the top monitoring frame.
