Description

A flexible intelligent inclinometer rope

technical field

The utility model relates to a monitoring device used in the fields of civil engineering, geological engineering and geological disaster monitoring, in particular to a monitoring intelligent inclination measuring rope capable of automatically measuring the continuous variation of deep horizontal displacement.

Background technique

In engineering practice and scientific research, it is often necessary to monitor the displacement of rock and soil or engineering structures at a certain depth below the ground. However, because the rock and soil mass or engineering structures in this part are buried deep underground, it is often impossible to measure directly. Therefore, people generally use inclinometers to monitor the displacement of a certain depth range underground.

At present, there are generally two types of inclinometers, which are divided into movable inclinometers and fixed inclinometers. Existing inclinometers are all made of inclinometer probes, reading instruments, cables and inclinometer tubes. When measuring, the inclinometer pipe is first buried inside the rock and soil mass and used as the guide rail of the inclinometer. The fixed inclinometer is to put the inclinometer probe into the specified depth along the guide rail. When the rock and soil deform, the entire inclinometer tube will deform along with the soil. The inclination probe measures the inclination angle, the data is transmitted to the reading instrument by the cable, and the horizontal displacement increment of the measured soil can be obtained through calculation. The measurement principle of the movable inclinometer is the same as that of the fixed inclinometer, the difference is that the movable inclinometer requires the surveyor to put the inclinometer probe into the predetermined depth, and then lift the cable section by section, so that the inclinometer probe can measure Horizontal displacement increment for a certain depth range.

However, these two inclinometric methods have great disadvantages. Due to structural limitations, fixed inclinometers can generally only measure the displacement of one or several specific depths, and cannot fully reflect the displacement changes in the specified depth range of underground rock and soil or underground structures. Moreover, the monitoring accuracy is limited and the monitoring effect is limited. Not ideal, it is difficult to reflect the actual deformation of the object. In addition, the mechanical structure of the inclinometer is complicated, and the manual operation is cumbersome. The operation process of the mobile inclinometer is cumbersome and relies too much on manual work. Professionals are required to visit the site for the whole process of measurement every time. However, due to the manual operation of the surveyors, the measurement results often have large errors. Moreover, it is necessary to install and operate an inclinometer for each measurement, and to measure a reading every time a depth position is measured, the operation repetition rate is high, and the efficiency is extremely low. In addition, for some monitoring objects in the field, due to the limitation of objective conditions, long-term on-site operation is not conducive to ensuring personal safety. For monitoring objects in remote areas, repeated long-distance transportation increases monitoring costs in disguise.

Through continuous measurement and interpretation, continuous displacement monitoring of monitoring positions in a certain depth range underground can be realized.

As a further technical improvement, the flexible protective tube is a flexible material tube of rubber, plastic or metal hose, or a flexible material tube in which steel wire or carbon fiber is arranged to increase strength.
