Description

Technical Field

[0001] The utility model relates to an intelligent electric-controlled deep displacement monitoring device, belonging to the technical field of geological displacement monitoring devices. Background Art

[0002] Deep inclinometer is the main technical means to monitor the deep deformation of side (slide) slopes. The deep displacement of landslides is monitored by drilling inclinometer. Borehole inclinometer reflects the deformation of the stratum through the deformation of the pre-buried inclinometer tube, and the deformation of the inclinometer tube is measured by the vertically movable inclinometer tube probe. During observation, the inclinometer tube probe moves upward from the bottom of the borehole through the pulley device and the inclinometer tube groove. The instrument measures the inclination of the location through two force-balanced accelerometers and records the angle data every 50 cm. The angle data is converted into lateral displacement, compared with the initial observation data, and multiple inclinometer data curves are superimposed to determine the parameters such as the deformation direction, depth, displacement and deformation rate of the inclinometer tube, thereby achieving the effect of monitoring the deep displacement of the stratum.

[0003] The existing testing methods can be divided into manual monitoring and automatic monitoring. The manual monitoring method is to use a certain length of cable (50m or 100m) with one end fixed to the inclinometer and the other end connected to the demodulator. First, put the connected inclinometer into the bottom of the inclinometer tube, and then manually lift the fixed length cable (50cm is the length of an inclinometer). After the data stabilizes, carry out a measurement, and complete the full-range deformation measurement of the deep borehole through multiple lifts.

[0004] The automated monitoring method is to connect multiple inclinometers (usually 4 to 5) in series at a certain interval and then connect them to cables, and place them at a fixed depth in the inclinometer tube. The other end of the cable is connected to the data acquisition and transmission device. The monitored deformation signal is interpreted by the device and transmitted to the monitoring system platform through wireless communication technology, realizing the function of remote automated monitoring.

[0005] By comparing manual monitoring and automated monitoring, we can see that manual monitoring can measure the entire borehole but has high labor costs, while automated monitoring requires more consumables but can monitor the entire range in real time. The advantages and disadvantages of the two monitoring methods are compared as follows:

[0028] (2) A foundation pit of a certain depth is excavated around the borehole, and then a "concave concrete pier" of a certain height (≥30 cm) is poured to construct an equipment placement platform 4 to fix the cable hoisting device 5 and the retracting and releasing distance measurement control device 6;
