Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit inclination measurement, in particular to a device for detecting the inclination angle of a side wall of a deep foundation pit. Background Art

[0002] Foundation pit refers to the space below the ground excavated for the construction of the foundation and basement of a building (including structures). It is a temporary project that provides a space so that the foundation masonry work can be carried out in the position specified by the design. Inclination measurement of foundation pits is to evaluate the stability and reliability of foundation pits by measuring the changes in the inclination angle of the foundation pit wall, which is of great significance for safe production. The traditional method of measuring the inclinometer of foundation pits is to first drill several vertical holes around the foundation pit wall, then lower the PVC pipe into the hole, and then manually lower the inclinometer into the PVC pipe hole, measure an inclination angle value every meter or half a meter, and finally evaluate the deformation degree of the foundation pit based on the changes in the inclination angle value.

[0003] In the patent with publication number CN117782021A, a foundation pit inclination measuring device is disclosed, which relates to the technical field of foundation pit inclination measurement. The device includes a fixed bottom plate, a motor assembly, a wire retracting assembly, a retracting length counting assembly, a pod-type inclinometer and a main control circuit board, wherein the fixed bottom plate is used to be fixed directly above the foundation pit wall hole and is provided with a wire-retracting hole aligned with the hole, and the pod-type inclinometer is used to be vertically and movably arranged in the foundation pit wall hole and includes a tubular pod upper part, a connecting tube, a tubular pod lower part, a slave control circuit board and a tilt detection module. Through the combination of software and hardware of the aforementioned components, the pod-type inclinometer can be lifted and lowered, and when it is found that the inclinometer reaches a certain target depth position, the tilt detection module is triggered to collect and return the tilt angle at the target depth position, so that the tilt angle of each target depth position can be fully automatically measured, reducing manual workload, avoiding the problem of inaccurate manual readings, and improving the safety of foundation pit operations. However, when the diameter of the vertical holes drilled around the foundation pit wall is large, the tilt detection module cannot fit the inner wall well, which will cause deviations in the measurement results, so the adaptability and practicality of this foundation pit inclination measurement device are poor.

[0028] like Figure 7 and Figure 8 As shown, it also includes a covering frame 12, an isolation cover 13, a water tank 14, a connecting pipe 15, a water pump 16 and a cleaning brush 17.
