[0033] The specific arrangement and function of the adjusting device 8 and the fixing device 9 will be described in detail below.

[0034] like Figure 1-Figure 5As shown, the adjustment device 8 includes a mounting block 81, which is rotatably connected to the inner wall of the measuring ruler 2, and a rotating rod 83 is fixedly connected to the inner wall of the mounting block 81, and the rotating rod 83 is rotatably connected to the inner wall of the measuring ruler 2. The side of the measuring ruler 2 is fixedly connected to the first level measuring instrument 82. By setting the mounting block 81, the angle of the measuring ruler 2 can be adjusted, so that after the foundation pit deformation angle is measured, the depth of the foundation pit deformation position can be measured. By setting the first level measuring instrument 82, the angle of the measuring ruler 2 can be conveniently adjusted to be perpendicular to the ground, thereby improving the accuracy of measuring the foundation pit deformation depth. The end of the rotating rod 83 away from the first level measuring instrument 82 is fixedly connected to a rotating gear 84, and the rotating gear 84 is rotatably connected to the side of the measuring ruler 2 away from the first level measuring instrument 82. A sliding groove is provided on the side of the measuring ruler 2 close to the rotating gear 84, and a slider 86 is slidably connected to the surface of the sliding groove on the measuring ruler 2. By providing the rotating gear 84 , the angle of the measuring ruler 2 can be easily adjusted, and the rotation of the measuring ruler 2 can be restricted, so that the slider 86 slidably connected to the surface of the slide groove on the measuring ruler 2 can move.

[0035] A clamping rod 85 is installed on one side of the measuring ruler 2 close to the rotating gear 84, and one end of the clamping rod 85 close to the measuring ruler 2 is fixedly connected to the slider 86, and a sliding rod 87 is slidably connected to the inner wall of the slider 86. By setting the clamping rod 85, the rotation of the rotating gear 84 can be restricted after the angle of the measuring ruler 2 is adjusted, thereby restricting the rotation of the measuring ruler 2. A spring 88 is sleeved on the surface of the sliding rod 87, and the two ends of the spring 88 are fixedly connected to the slider 86 and the measuring ruler 2 respectively. By setting the sliding rod 87, the position of the spring 88 can be restricted, and by setting the spring 88, the position of the slider 86 can be restricted.

[0036] like Figure 1 and Figure 6 As shown, the fixing device 9 includes two plug rods 91, both of which are slidably connected to the inner wall of the positioning plate 1, and one end of the two plug rods 91 is fixedly connected to a control board 92. By setting the plug rods 91, the positioning plate 1 can be conveniently fixed on the ground, and by setting the control board 92, the two plug rods 91 can be controlled to move at the same time. A connecting plate 93 is fixedly connected to the surface of the two plug rods 91, and a second level measuring instrument 94 is fixedly connected to the side of the connecting plate 93. The second level measuring instrument 94 can be connected to the plug rods 91 by setting the connecting plate 93, and by setting the second level measuring instrument 94, it can be observed whether the two plug rods 91 are parallel to the ground.

[0037] A fixing block 95 is fixedly connected to one side of the positioning plate 1 close to the control plate 92, and a control screw 96 is threadedly inserted into the inner wall of the control plate 92, and one end of the control screw 96 is rotatably connected to the fixing block 95. The control screw 96 can be arranged to control the movement of the control plate 92, and the fixing block 95 is arranged to ensure that the control screw 96 can be connected to the positioning plate 1 while ensuring that the control screw 96 can rotate.

[0038] Working principle: When using the foundation pit deformation measuring device to measure the deformation of the foundation pit, first move the positioning plate 1 close to the edge of the foundation pit, and then place the measuring ruler 2 close to the inner wall of the foundation pit. At this time, the deformed inner wall of the foundation pit pushes the rotating ruler 3, so that the moving block 4 slides on the inner wall of the positioning plate 1, and then rotate the fastening screw 5 to fix the position of the rotating ruler 3. The deformation position and deformation angle of the foundation pit can be recorded through the pointer 6 and the inclination sensor 7. After the deformation angle measurement of the deformation position of the foundation pit is completed, the movable clamping rod 85 drives the sliding block 86 to slide on the surface of the sliding rod 87, so that the clamping rod 85 moves away from the rotating gear 84, and the restriction on the position of the rotating gear 84 is released. Then, the fastening screw 5 is rotated to release the restriction on the position of the rotating ruler 3, and then the measuring ruler 2 is rotated. The measuring ruler 2 is placed in a vertical state with the ground through the first horizontal measuring instrument 82, and the clamping rod 85 is loosened. Under the action of the elastic force of the spring 88, the clamping rod 85 moves close to the rotating gear 84 to limit the position of the rotating gear 84. At this time, the depth of the deformation position of the foundation pit is measured and recorded by the pointer 6. The measuring ruler 2 can be rotated by setting the mounting block 81. The position of the measuring ruler 2 can be restricted by the rotating rod 83 without affecting the rotation of the measuring ruler 2. The adjusting device 8 can be provided to facilitate the adjustment of the angle of the measuring ruler 2, so that the depth of the deformation position of the foundation pit can be measured after the deformation angle measurement of the deformation position of the foundation pit is completed, thereby ensuring the accuracy of the foundation pit deformation measurement as much as possible.

[0039] When it is necessary to fix the positioning plate 1 on the edge of the foundation pit, first move the positioning plate 1 close to the edge of the foundation pit, then rotate the control screw 96 to make it rotate on the surface of the fixing block 95. The rotation of the control screw 96 causes the control plate 92 to drive the two insertion rods 91 to move close to and insert into the ground, thereby fixing the positioning plate 1. The second level measuring instrument 94 on the connecting plate 93 can be used to observe whether the positioning plate 1 is level with the ground after installation. By setting the fixing device 9, when it is necessary to measure the deformation of the foundation pit, the positioning plate 1 can be installed horizontally at the edge of the foundation pit as much as possible, thereby ensuring the accuracy of the foundation pit deformation measurement using the foundation pit deformation measuring device as much as possible.
