Embodiment 1
[0059] Such as figure 1 As shown, the present invention is a shield tunnel surrounding rock deformation advanced monitoring structure, including a monitoring body composed of several monitoring sections 1, flexible connecting sections 2 and angle sensing devices 3 located on the monitoring section 1, wherein the flexible connecting section 2 The two ends are respectively connected to the first section and the tail end of two adjacent monitoring sections 1, and the angle sensing device 2 is used to monitor the angle between the monitoring section 1 on it and the horizontal plane and the vertical plane.
Embodiment 2
[0061] On the basis of Embodiment 1, the flexible connecting section 2 respectively connects each adjacent monitoring section 1 with bolts in turn, and connects the cables of the angle sensing devices 3 in each adjacent monitoring section 1 during connection. In order to further fix the position of the monitoring body and protect it, the head end of the monitoring section 1 close to the A end is connected with a guide head 7 with a pointed cone at one end by bolts, and when the monitoring body is installed through the guide head 7 , play a guiding role.
[0062] Moreover, a flexible sleeve 5 is sleeved on the monitoring section 1 and the flexible connecting section 2, and the flexible sleeve 5 sleeves the monitoring main body therein. At this time, the guide head 7 is connected to the end of the flexible sleeve 5 near the A end, and the gap between the guide head 7 and the flexible sleeve 5 is sealed with a sealant, and waterproof treatment is performed to prevent the filler f...
Embodiment 3
[0065] Such as figure 2 As shown, on the basis of embodiment 2, when in use, the monitoring main body is located in the advance borehole 8, and the advance borehole 8 is an obliquely upwardly inclined borehole above the unexcavated section 10 in the surrounding rock. The advance borehole 8 and The angle between the horizontal straight lines is 15°, the length of the advanced drilling 8 is 10m, and the length of a monitoring section 1 is 40cm.
[0066] In Embodiment 2, the monitoring body with the flexible sleeve 5 and the lead wire head 7 is placed in the advanced borehole 8, and after placement, a filler layer 9 for fixing the monitoring body is filled between the advanced borehole 8 and the monitoring body, The filler layer 9 of the device is cement mortar. After fixing, since the monitoring section 1 is a hollow steel pipe inside, the angle sensing device 2 is located inside the steel pipe. The angle sensing device 2 includes a first angle sensor and a second angle sensor...
