[0012] To further illustrate the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the specific implementation, structure, features and effects according to the utility model are described in detail as follows in combination with the drawings and preferred embodiments.

[0013] Example 1:

[0014] As shown in Figure 1 , Figure 2 The utility model discloses a kind of deep foundation pit side wall inclination monitoring devices, including laser emitter 2 and laser reflector 3, the laser emitter 2 is set to the top of the side wall to be measured of foundation pit, laser reflector 3 is fixed with interval on the side wall to be measured of foundation pit, a row of interval laser emission port is provided on the laser emitter 2, the interval between the laser emission port and the side wall to be measured of foundation pit is same, laser emitter 2 is located in the range of foundation pit, the laser reflector 3 is set to different positions of the side wall to be measured of foundation pit, the laser emission port of laser emitter 2 emits laser and is irradiated on different laser reflector 3 and reflected to the adjacent side wall of the side wall to be measured of foundation pit.

[0015] The laser emitter 2 is a commercially available product, and a plurality of laser emitting ports are arranged inside the laser emitter 2 to emit laser light. The laser emitter 2 is fixed to the top of the side wall to be detected of the deep foundation pit 1 through a mounting frame, and the laser emitting ports extend into the foundation pit. Meanwhile, the position of the mounting frame is adjusted to ensure that the distance between each laser emitting port and the side wall to be detected is the same. A plurality of laser reflectors 3 are arranged on the side wall to be detected of the deep foundation pit 1 at intervals, and the installation directions of the laser reflectors 3 are consistent. In this way, the laser light emitted by the laser emitter 2 is reflected by the laser reflectors 3 to the adjacent side wall, and a vertical straight line is formed or the reflection angles of the laser reflectors 3 are inconsistent, but the laser points on the side wall to which the laser light emitted by all the laser emitters 2 is finally reflected are arranged in a vertical straight line. During the entire monitoring process, the laser emitter 2 is continuously turned on. If the side wall to be detected of the deep foundation pit 1 is inclined, the laser reflectors 3 will be inclined, thereby changing the landing points of the reflected laser light. The technician can determine the inclination degree or local inclination or overall inclination of the side wall to be detected according to the landing points of the laser light.

[0016] The laser reflectors 3 are arranged on the side wall to be detected of the deep foundation pit in a horizontal direction at intervals and in a vertical direction at intervals. The laser reflectors 3 are arranged on the side wall to be detected in a staggered manner, that is, the laser light emitted by at least one laser emitting port of the upper laser emitter 2 can irradiate the laser reflectors 3, so that each laser reflector 3 has laser light reflected to the side wall to form a laser point as a reference.

[0017] As shown in Figure 3 The structure of the laser reflector 3 includes a rectangular mounting plate 4, a mirror plate 5 is arranged on the rectangular mounting plate 4 through a rotating shaft 10, and an adjusting mechanism is arranged between the rectangular mounting plate 4 and the back of the mirror plate 5. The adjusting mechanism is used to adjust the included angle between the mirror plate 5 and the rectangular mounting plate 4. The rectangular mounting plate 4 can be used to conveniently level the laser reflector 3 during installation, so that all the laser reflectors 3 are consistent. The rectangular mounting plate 4 of the laser reflector 3 is fixedly connected to the side wall to be detected, and the fixing form can be selected according to actual needs, such as bonding. The rectangular mounting plate 4 of the laser reflector 3 is rotationally connected to the mirror plate 5 through the rotating shaft 10. Of course, the included angle between the axis of the rotating shaft 10 of each laser reflector 3 and the side wall of the rectangular mounting plate 4 is the same. In this way, only one side of the rectangular mounting plate 4 of the laser emitter needs to be kept horizontal during installation, and the rotating shaft 10 can be kept consistent. Therefore, through the adjusting mechanism of the laser reflector 3, all the mirror plates 5 can be adjusted to be consistent, that is, all the mirror plates are parallel to each other. In this way, the reflection of the laser light can be kept consistent and the angle can be consistent.

[0018] The adjusting mechanism is that an adjusting rod 6 is arranged on the back of the mirror plate 5 through a pin shaft, an adjusting rod 6 is arranged on the rectangular mounting plate 4 through a pin shaft, the ends of the two adjusting rods 6 are connected with an adjusting block 7 through pin shafts, screw holes are arranged on the adjusting block 7, a screw rod 8 is arranged in the screw holes, one end of the screw rod 8 is swing-connected with the rectangular mounting plate 4, and an adjusting handle 9 is arranged at the other end of the screw rod 8.

[0019] The adjusting mechanism adopts two-section adjusting rods 6, the adjusting rods 6 are arranged between the adjusting block 7 and the mirror plate 5 and between the adjusting block 7 and the rectangular mounting plate 4 respectively, the two ends of the adjusting rods 6 are swing-connected through pin shafts, the adjusting block 7 is threadedly connected with the screw rod 8, the screw rod 8 can only swing, and the screw rod 8 is perpendicular to the rotating shaft 10, so that the position of the adjusting block 7 is changed when the screw rod 8 rotates, the angle between the two adjusting rods 6 is changed, the position of the mirror plate 5 is adjusted, and finally the included angle between the mirror plate 5 and the rectangular mounting plate 4 is changed. Of course, in actual use, the mirror plates 5 of all the laser reflectors 3 are adjusted to the same state, and the mirror plate 5 is adjusted so that the landing position of the laser after being reflected by the mirror plate 5 is in a proper position, and observation is facilitated.
