Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering safety monitoring technology, and in particular to a deep foundation pit settlement monitoring device. Background Technology
[0002] In various civil engineering fields, settlement is a key monitoring indicator in the construction of infrastructure such as buildings, bridges, roads, and dams. For buildings, uneven settlement can lead to problems such as wall cracking and door and window deformation. Taking multi-story residential buildings as an example, uneven foundation settlement will cause internal forces in the building structure. As settlement progresses, visible cracks may appear in the walls, seriously affecting the normal use and safety of the building. In bridge engineering, the settlement of bridge piers will change the stress state of the bridge. Excessive pier settlement will cause the internal forces of the bridge superstructure to redistribute, which may lead to cracks in the beams and even endanger traffic safety. According to relevant research, many bridge defects are related to foundation settlement. For road engineering, roadbed settlement will cause uneven road surfaces. Under the repeated action of traffic loads, the road surface is prone to potholes and undulations, reducing the comfort and service life of the road. In particular, the control of roadbed settlement is even more important for heavy traffic roads such as highways.
[0003] Early settlement monitoring relied mainly on manual measurement, with the level being the most commonly used tool. It establishes a horizontal line of sight and reads the leveling rod to determine the height difference between two points. This method has a certain degree of accuracy, but the operation process is cumbersome. When conducting settlement monitoring on large construction sites, multiple leveling points need to be set up around the building, and surveyors need to measure each point one by one. Moreover, the instrument must be set up and the readings must be accurate for each measurement. Total stations can measure angles and distances, and calculate the three-dimensional coordinates of the monitoring points through resection to obtain settlement data. However, total station measurements also have the problem of low efficiency. In complex construction site environments with many obstacles and construction machinery, the measurement line of sight of the total station can be obstructed, affecting the smooth progress of the measurement.

[0009] A drill bit is fixedly connected to the bottom of the detection column, and a top plate is fixedly connected to the outer wall of the detection column near the top edge.
[0010] As a further description of the above technical solution:
[0011] A dust baffle is fixedly connected to the outer wall of the support column near the top edge, and a reflective strip is fixedly connected to the bottom edge of the dust baffle.

[0016] As a further description of the above technical solution:
[0017] The top of the base has a threaded groove, and the top of the base also has multiple round holes.
[0018] As a further description of the above technical solution:
[0019] The inner wall of the circular hole is threaded with a cross screw, and the top of the detection column is fixedly connected with a support rod.

[0021] 1. In this utility model, during testing, the testing column is inserted into the soil, and the support column is stably erected on a flat area using cross screws and a base. The user operates the controller to start the laser rangefinder to measure and record the initial distance. Subsequently, the solar panel on the top of the support column converts light energy into electrical energy to power the laser rangefinder for real-time distance measurement.

[0037] Please see the appendix Figure 2 - Appendix Figure 4 The bottom of the support column 5 is fixedly connected to a threaded column 20, and the bottom of the threaded column 20 is threadedly connected to a base 22 to ensure stable installation. The top of the base 22 is provided with a threaded groove 21, and the top of the base 22 is provided with multiple round holes 23.

[0038] Specifically, the bottom of the support column 5 is fixedly connected to the threaded column 20. This connection method ensures the stability of the support column 5 and allows the entire structure to be firmly erected in the required position. The bottom of the threaded column 20 is connected to the base 22 by threads, further enhancing the stability of the structure. The top of the base 22 has threaded grooves 21, which facilitate subsequent installation and adjustment. In addition, multiple round holes 23 are evenly opened on the top of the base 22. The inner walls of these round holes 23 are connected to the cross screws 24 by threads, making the installation and disassembly of the entire device more flexible and convenient. The top of the detection column 1 is fixedly connected to the support rod 25, which not only enhances the stability of the detection column 1, but also provides reliable support for fixing the position of the buzzer 208, ensuring the stability and accuracy of the buzzer 208 during operation.
[0039] Working principle: When testing is required, the testing column 1 is buried in the soil. After the support column 5 is erected stably on a flat area using the cross screws 24 and the base 22, the user controls the controller 11 to let the laser rangefinder 13 shine on the reflective prism 7 to measure and record the initial distance. Subsequently, the solar panel 10 on the top of the support column 5 absorbs light energy and converts it into electrical energy to power the laser rangefinder 13 for real-time distance measurement. The user can observe the values measured by the controller 11 to record the real-time settlement height without worrying about energy supply issues. This greatly solves the problem of needing to use cumbersome tools for monitoring and brings convenience to the user.
[0040] After the detection column 1 is buried in the soil, when the soil pressure changes, the conical head 207 on the outer wall of the detection column 1 begins to squeeze towards the center. By sliding inside the support column 204, it drives the push button 205 to slide, causing the push button 205 to press against the pressure sensor 203. At this time, it indicates that the pressure is too high, and the buzzer 208 on the top of the detection column 1 sounds an alarm, prompting the staff to make the next work arrangements, thus ensuring the safety of the staff.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
