Tilt monitoring: according to the actual monitoring needs, the connection tubes and extension tubes are increased or decreased, and then the bottom tube, extension tube and top tube spliced ​​by the connection tube are vertically inserted into the position to be detected, and then the adjustment mechanism is placed above the top tube, and the existing connection rope is wound around the outer surface of the winding disk, and one end of the connection rope is passed through the guide tube, so that one end of the connection rope can be firmly connected to the mobile frame, and then the second measuring mechanism is inserted into the top tube through the mobile frame, and the existing white paper is stably clamped in the pressing frame through the pressing plate. At this time, by rotating the adjustment limit rods in different directions, the support frame can be continuously adjusted under the support of the limit tubes and limit rods in different directions, so that the position of the pipe rack can be offset with the support frame. At this time, under the support of the support ball, the pipe rack is always kept in a vertical state above the top frame under the traction of the counterweight, and then the bottom end of the pipe rack can be located above the top tube. At this time, by controlling the lighting of the light source pen body, the light source pen body can generate light spots on the surface of the existing white paper, and then the camera device body passes through the pipe rack The position of the light spot is recorded in real time, and then the winding motor is controlled to start, so that the winding motor drives the winding disc to rotate through the first linkage wheel, the second linkage wheel and the linkage belt, so that the rotating winding disc can continuously release the existing connecting rope, so that the existing connecting rope can gradually put the second measuring mechanism into the bottom tube at a uniform speed, and at the same time, the driving motor is controlled to start, so that the driving motor can drive the rotor to rotate rapidly, so that the rapidly rotating rotor can keep the light source pen body in a vertical state at all times under the support of the second rotating frame and the first rotating frame, and then in the process of the light source pen body gradually falling into the bottom tube, if the top tube, the connecting tube and the bottom tube do not maintain the original vertical state, then in the process of the light source pen body falling in the vertical state, the initial light spot of the light source pen body will gradually deviate from the origin position, at this time, according to the light spot offset distance, the inclination of the first measuring mechanism can be conveniently and intuitively observed, and at the same time, the length of the existing connecting rope and the light spot offset distance are used as two right-angled sides, so that the inclination angle of the first measuring mechanism can be obtained more conveniently;

[0019] S2. Settlement monitoring: Select a suitable building to build the standard point, and then start the rotating motor through control, so that the rotating motor can cooperate with the rotating gear to drive the ring gear to rotate, and then the rotating ring gear can drive the protective frame to rotate, so that the rotating protective frame can adjust the monitoring angle of the camera device body in the horizontal direction through the mounting bracket, and then start the steering motor through control, so that the steering motor can drive the camera device body to rotate in the vertical direction, and then the camera device body can maintain a fixed angle to compare the shooting position of the standard point, and then the settlement condition of the position to be detected can be monitored according to the actual monitoring needs.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0021] (1) In the present invention, when in use, the connection tube and the extension tube are increased or decreased according to the actual monitoring needs, and then the bottom tube, the extension tube and the top tube spliced ​​by the connection tube are vertically inserted into the position to be detected, and then the adjustment mechanism is placed above the top tube, and the existing connection rope is wound around the outer surface of the winding drum, and one end of the connection rope is passed through the guide tube so that one end of the connection rope can be firmly connected to the moving frame, and then the second measuring mechanism is inserted into the top tube through the moving frame, and the existing white paper is stably clamped in the pressing frame by the pressing plate. At this time, by rotating different The azimuth adjustment limit rod enables the support frame to continuously adjust its position under the support of the limit tube and the limit rod in different azimuths, so that the position of the tube rack can be offset with the support frame. At this time, under the support of the support ball, the tube rack is always kept in a vertical state above the top frame under the traction of the counterweight block, so that the bottom end of the tube rack can be located above the top tube. At this time, the light source pen body is controlled to light up, so that the light source pen body can generate a light spot on the surface of the existing white paper, and then the camera device body records the light spot position in real time through the tube rack, and then starts the control. The winding motor drives the winding disk to rotate through the first linkage wheel, the second linkage wheel and the linkage belt, so that the rotating winding disk can continuously release the existing connecting rope, so that the existing connecting rope can gradually put the second measuring mechanism into the bottom tube at a uniform speed. At the same time, by controlling the start of the driving motor, the driving motor can drive the rotor to rotate rapidly, so that the rapidly rotating rotor can keep the light source pen body in a vertical state at all times under the support of the second rotating frame and the first rotating frame. Then, in the process of the light source pen body gradually falling into the bottom tube, if the top tube, the connecting tube and the bottom tube do not maintain the original vertical state, then in the process of the light source pen body falling in the vertical state, the initial light spot of the light source pen body will gradually deviate from the origin position. At this time, the inclination of the first measuring mechanism can be conveniently and intuitively observed according to the light spot offset distance. At the same time, by using the existing connecting rope length and the light spot offset distance as two right-angled sides, the inclination angle of the first measuring mechanism can be obtained more conveniently, so that the equipment can conveniently monitor the inclination of the soil at the position to be detected, so that the equipment can efficiently realize its due functions.

10. A method for using a soil monitoring system around a foundation pit, characterized in that: The soil monitoring system for the surrounding area of ​​a foundation pit as claimed in claim 9 comprises the following steps: S1. Tilt monitoring: according to actual monitoring needs, the connecting tube (302) and the extension tube (303) are increased or decreased, and then the bottom tube (304), the extension tube (303) and the top tube (301) spliced ​​by the connecting tube (302) are vertically inserted into the position to be detected, and then the adjustment mechanism (2) is placed above the top tube (301), and the existing connecting rope is wound around the outer surface of the winding drum (202), and one end of the connecting rope is passed through the guide tube (203) so that one end of the connecting rope can be firmly connected to the moving frame (401), and then the second measuring mechanism (4) is inserted into the top tube (301) through the moving frame (401), and the existing white paper is stably clamped on the top tube (301) by the pressing plate (207). Inside the pressing frame (206), by rotating the adjusting limit rod (105) in different directions, the position of the support frame (101) can be continuously adjusted under the support of the limit tube (106) and the limit rod (105) in different directions, so that the position of the pipe frame (108) can be offset with the support frame (101). At this time, under the support of the support ball (107), the pipe frame (108) is always kept in a vertical state above the top frame (205) under the traction of the counterweight block (109), and then the bottom end of the pipe frame (108) can be located above the top tube (301). At this time, by controlling the lighting of the light source pen body (406), the light source pen body (406) can be generated on the surface of the existing white paper. The light spot is detected by the camera body (115) through the tube frame (108), and the camera body (115) records the light spot position in real time. The winding motor (204) is then controlled to start, so that the winding motor (204) drives the winding disc (202) to rotate through the first linkage wheel, the second linkage wheel and the linkage belt, so that the rotating winding disc (202) can continuously release the existing connection rope, so that the existing connection rope can gradually put the second measuring mechanism (4) into the bottom tube (304) at a uniform speed. At the same time, the driving motor (405) is controlled to start, so that the driving motor (405) can drive the rotor (404) to rotate rapidly, so that the rapidly rotating rotor (404) can rotate between the second rotating frame (403) and the first rotating frame (403). The light source pen body (406) is kept in a vertical state at all times under the support of the frame (402). Then, when the light source pen body (406) gradually falls into the bottom tube (304), if the top tube (301), the connecting tube (302) and the bottom tube (304) do not maintain the original vertical state, the initial light spot of the light source pen body (406) will gradually deviate from the origin position during the falling process of the light source pen body (406) in the vertical state. At this time, the tilting state of the first measuring mechanism (3) can be conveniently and intuitively observed according to the light spot offset distance. At the same time, by placing the existing connecting rope length and the light spot offset distance as two right-angled sides, the tilting angle of the first measuring mechanism (3) can be obtained more conveniently. S2, settlement monitoring: Select a suitable building to construct a standard point, and then control the start of a rotating motor (113) so that the rotating motor (113) cooperates with a rotating gear (114) to drive the gear ring (112) to rotate, and then the rotating gear ring (112) can drive the protective frame (111) to rotate, so that the rotating protective frame (111) can adjust the monitoring angle of the camera device body (115) in the horizontal direction through the mounting frame, and then control the start of a steering motor (116) so that the steering motor (116) can drive the camera device body (115) to rotate in the vertical direction, and then the camera device body (115) can maintain a fixed angle to compare the shooting position of the standard point, and then the settlement condition of the position to be detected can be monitored according to actual monitoring needs.
