Description
Technical Field
The utility model relates to a civil engineering technical field especially involves a can follow the semi-rigid push rod of inclinometer that the horizontal direction measurement subsides.
Background
The inclinometer (matched with an inclinometer pipe) can be used for measuring the horizontal displacement of a deep soil body and is widely applied to monitoring and measuring of various projects such as side slopes, foundation pits and the like. The conventional inclinometer consists of a probe, a data line and an acquisition instrument, and the measurement process is as follows: vertically drilling a hole in the stratum to a designed depth, and inserting an inclinometer pipe with a cross slot into the hole; placing the probe at the bottom of the inclinometer pipe along the cross slot, and slowly lifting the probe by pulling the data line; measuring the included angle between the probe and the vertical direction at certain intervals, and recording the included angle in the acquisition instrument; and (4) completing the measurement of the included angle at each depth along the inclinometer pipe, and calculating the horizontal displacement of the soil body at each depth through post-processing.
The technology for measuring the horizontal displacement of the deep soil along the vertical direction is mature. However, in recent geotechnical engineering practice, the requirement of measuring the vertical settlement of deep soil along the horizontal direction also appears. In the process of filling a high fill embankment, the vertical settlement of soil at the bottom of the embankment needs to be measured along the cross section of the embankment; after the tunnel portal section is supported by the advanced pipe shed, the vertical settlement of the tunnel portal section needs to be measured along the longitudinal direction of the pipe shed. In principle, the inclinometer pipe with the cross groove can be horizontally arranged, and the vertical settlement of the soil body (or the pipe shed) at each measuring point can be calculated by measuring the included angle between the probe and the horizontal direction.
However, the need to measure vertical settlement in the horizontal direction is clearly not fulfilled with conventional inclinometers, and there are at least three difficulties to overcome. 1. The settlement is measured in the horizontal direction, and a large pushing force (or pulling force) needs to be provided for the probe to enable the probe to be pushed forwards (or pulled backwards) along the cross groove in the inclinometer, so that a push rod needs to be additionally arranged behind the probe. 2. The horizontal inclinometer tube embedded in the soil body generates obvious bending deformation due to the drilling precision or the self settlement of the soil body and the like, and if a push rod with too high rigidity is used, the horizontal inclinometer tube cannot adapt to the bending deformation of the inclinometer tube, so that the probe is clamped in the forward jacking (or backward pulling) process. 3. The primary direction sensor in an inclinometer probe is the gyroscope, whose initial orientation is oriented vertically, which measures the angle of the probe from vertical, but obviously not from horizontal.
