[0030] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0031] like Figures 1-6As shown, a construction foundation pit settlement safety monitoring device of the present invention includes multiple installation boxes 1 and controllers 2. An alarm 23 is fixedly installed on the upper end surface of the installation box 1. The alarm is electrically connected to the controller 2. The alarm 23 is used to alarm when the foundation pit settles, reminding the staff that the foundation pit has settled, making the device safer and more reliable. The controller 2 is used to control the electric components of the device, and can also display the monitoring results and calibrate the monitoring data. An alarm device is provided inside the controller 2 to alarm when the foundation pit settles. The installation box 1 is electrically connected to the controller 2. The upper end surface of the installation box 1 is fixedly installed with an alarm 23. The concave fixed plate 3 has a moving block 4 installed on the upper end surface of the fixed plate 3 through a sliding mechanism. An indicator mark 21 is fixedly installed on the outer wall of the moving block 4. A scale 22 is provided on the inner bottom surface of the fixed plate 3. The indicator mark 21 cooperates with the scale 22 to display the settlement distance of the foundation pit for auxiliary detection, making the monitoring result more intuitive. The sliding mechanism includes a slide groove 12 horizontally opened on the inner bottom surface of the fixed plate 3. The moving block 4 is slidably connected to the inner wall of the slide groove 12. The slide groove 12 is provided to realize the connection between the fixed plate 3 and the moving block 4, the adapter block 7, and the connecting block 13, so that the moving block 4, the adapter block 7, and the connecting block 13 can slide stably laterally along the slide groove 12, so that the monitoring result can be more intuitive. The feedback result is more accurate. The upper end surface of the moving block 4 is fixedly installed with a displacement sensor feedback end 5. The side wall of one end of the fixed plate 3 is fixedly installed with a displacement sensor signal end 6. The displacement sensor feedback end 5 and the displacement sensor signal end 6 are both electrically connected to the controller 2. When the foundation pit settles, the detection block 11 indirectly pulls the displacement sensor feedback end 5 to move, so that the distance between the displacement sensor feedback end 5 and the displacement sensor signal end 6 is enlarged. The displacement distance is monitored and displayed by the controller 2 to achieve real-time monitoring. The moving block 4 is connected to the adapter block 7 through the adapter adjustment mechanism. The outer wall of the adapter block 7 is fixed with a steel wire 8 that runs through the side wall of the fixed plate 3. An auxiliary block 9 is fixedly installed on the outer wall of the installation box 1, and a detection rod 10 is vertically movable through the auxiliary block 9. A detection block 11 is fixedly installed on the lower end of the detection rod 10, and the upper end of the detection rod 10 is fixedly connected to the steel wire 8. By setting up multiple installation boxes 1 and matching monitoring components, this device can monitor the settlement of multiple points in the foundation pit, and provide more comprehensive coverage of the settlement monitoring of the foundation pit. It can monitor and discover the settlement of the foundation pit in real time, and has higher safety. At the same time, the height of the detection block 11 can be adjusted by using the combined distance of the moving block 4, the adapter block 7 and the connecting block 13, so that the detection block 11 can be fitted with the bottom surface of the foundation pit of different depths, and has stronger applicability.

[0032] The transfer adjustment mechanism includes a connecting block 13 provided on the inner bottom surface of the fixed plate 3. The connecting block 13 and the transfer block 7 are slidably connected to the inner wall of the slide groove 12. A transfer bar 14 is fixedly installed on the outer wall of the transfer block 7. The transfer bar 14 movably passes through the connecting block 13, the movable block 4 and the side wall of the fixed plate 3. A plurality of threaded holes 15 are opened on the upper end surface of the transfer bar 14 at equal intervals. A first screw 16 is vertically threadedly installed on the upper end surface of the connecting block 13. The first screw 16 is threadedly connected to one of the threaded holes 15. The outer wall of the movable block 4 A second screw 17 is installed for horizontal rotation, and the second screw 17 threadedly passes through the connecting block 13. A transfer bar 14 is provided to cooperate with the first screw 16 to connect the transfer block 7 and the connecting block 13, so that the distance between the transfer block 7 and the connecting block 13 can be roughly adjusted, so that the detection block 11 can be suitable for foundation pits of different depths. The second screw 17 can be rotated to adjust the distance between the moving block 4 and the connecting block 13, and the distance between the moving block 4 and the connecting block 13 can be finely adjusted to make the detection block 11 fit the bottom surface of the foundation pit.

[0033] A bracket 19 is fixedly installed on the corner of the outer wall of the installation box 1, and an auxiliary wheel 20 is rotatably installed on the end of the bracket 19. The steel wire 8 slides with the surface of the auxiliary wheel 20. The auxiliary wheel 20 is used to support the steel wire 8 and change the transmission direction of the steel wire 8. At the same time, it avoids friction between the steel wire 8 and the installation box 1, replaces sliding friction with rolling friction, reduces the wear of the steel wire 8, and extends the service life of the steel wire 8. A telescopic rod 18 is vertically fixedly installed on the corner of the upper end face of the detection block 11. The upper end of the telescopic rod 18 is fixedly connected to the auxiliary block 9. The telescopic rod 18 performs an auxiliary connection between the auxiliary block 9 and the detection block 11, and performs auxiliary limiting on the detection block 11, so that the detection block 11 can only move up and down, making the monitoring feedback results more accurate.

[0034] A construction foundation pit settlement safety monitoring method, using construction foundation pit settlement safety monitoring equipment, includes the following steps:

[0035] S1: Install the installation box 1 on the ground at the edge of the foundation pit to be tested, so that the side wall of the installation box 1 is flush with the side wall of the foundation pit, and the detection block 11 is in contact with the bottom surface of the foundation pit. At the same time, adjust the calibration monitoring result so that the monitoring reading is zero;

[0036] When the S2 foundation pit settles, the detection block 11 descends along with the bottom surface of the foundation pit. The detection block 11 indirectly pulls the moving block 4 to move through the transmission of the detection rod 10, steel wire 8, adapter block 7 and other components, causing the displacement sensor feedback end 5 on the moving block 4 to displace, thereby realizing settlement monitoring;

[0037] The S3 displacement sensor feedback terminal 5 cooperates with the displacement sensor signal terminal 6 to convert the sinking distance of the detection block into data and displays it using the controller 2.

[0038] The embodiment of the present invention further provides a construction foundation pit settlement safety monitoring method, the specific working principle of which includes the following steps:

[0039] The cam 13 is fixed to the bottom of the cam 13 and the cam 14 is fixed to the bottom of the cam 13. ... The measuring blocks 11 are respectively located at different points of the foundation pit to monitor the settlement of multiple points of the foundation pit, so that the monitoring coverage is wider. When settlement occurs at a certain point of the foundation pit, the detection block 11 at the corresponding point moves downward synchronously due to the settlement of the bottom of the foundation pit. The detection block 11 pulls the corresponding adapter block 7 to move through the transmission of the steel wire 8, and the adapter block 7 pulls the connecting block 13 to move through the transmission of the adapter bar 14. The connecting block 13 pulls the moving block 4 to move through the transmission of the second screw 17. The displacement sensor feedback end 5 moves with the corresponding moving block 4. The displacement sensor feedback end 5 is indirectly pulled away from the corresponding displacement sensor signal end 6 by the detection block 11. The displacement sensor feedback end 5 cooperates with the displacement sensor signal end 6 to perform monitoring and feedback, and displays the sinking distance data of the detection block 11 on the controller 2. When the sinking distance reaches the value set by the controller 2, the alarm 23 and the alarm device in the controller 2 simultaneously sound an alarm reminder.
