Description

Sliding inclinometer

Technical Field

The utility model relates to the technical field of inclinometers, in particular to a sliding inclinometer.

Background

The sliding type inclinometry system is widely applied to the scenes such as construction monitoring of building engineering, stability monitoring of a dam, preventive monitoring of geological disasters and the like, and is mainly used for monitoring deep horizontal displacement of soil layers with different depths below the ground surface. The size, rate and depth of the deep soil layer movement can be determined by analyzing the measurement data at different time points in the monitoring period.

In the excavation process of a foundation pit (taking the excavation of the foundation pit as an example), soil layers with all depths at the edge of the foundation pit have a tendency to incline towards the interior of the foundation pit, and in order to ensure the safety of the foundation pit, the size, the speed and the like of displacement of the soil layers with all depths at the edge of the foundation pit towards the interior of the foundation pit need to be monitored in the whole excavation process. In order to represent the displacement condition of soil layers with different depths at the edge of a foundation pit, a plurality of deep holes are distributed at the periphery of the foundation pit before the foundation pit is excavated, and inclinometer pipes, namely inclinometer holes and inclinometer pipes shown in the figure, are buried in the holes. And the soil layer displacement conditions of different depths at the edge of the foundation pit can be characterized by the deformation conditions of the inclinometer pipe at the different depths. The inclinometer is an instrument for measuring the deformation degree of the inclined tube. The inclinometer pipe is provided with two groups of orthogonal guide grooves, one group of guide grooves faces the center direction of the foundation pit, and the upper guide wheel and the lower guide wheel of the sliding inclinometer are ensured to slide into the group of guide grooves in the measuring process. In the measuring process, the sliding inclinometer is slid to the bottom of the inclinometer, the inclination angle of a single point at the measuring depth can be measured through a sensor built in the inclinometer, the single point offset at each measuring depth can be obtained through a trigonometric function relation, and the accumulated offset of each depth can be obtained through accumulation, namely the tube shape of the inclinometer (the shape of the inclinometer). In the process of excavating a foundation pit, at different time points, the tubular shape of the inclinometer pipe is changed and tends to the inside of the foundation pit more and more; if we use the inclinometer tube shape before excavation as the standard, a new tube shape is generated on each subsequent measurement date, and the change of the new tube shape and the tube shape before excavation is the tube shape change of the current measurement date. The purpose of the sliding inclinometer is to measure and calculate the tubular change at different time points after excavation, and if the tubular change exceeds the allowable range, alarm information is issued to warn the safety occurrence risk of foundation pit excavation engineering.

In practical use, we find that the inclinometer of the prior art is generally a whole pipe, and the upper and lower groups of guide wheels are both rotatably mounted on the inclinometer through connecting rods, so that the working surface of the inclinometer is not easy to be kept flat, and the unevenness has a great influence on the final measurement precision, therefore, we propose a sliding inclinometer to solve the problem.
