Problems solved by technology

Although the internal deformation monitoring of rock and soil using deep buried sensors can detect the deformation of rock and soil earlier than external displacement monitoring, but the cost is high, the control range of monitoring points is small, and the pressure of deep rock and soil has a great impact on displacement monitoring. The interference of the device is relatively large, which still cannot meet the needs of engineering safety guarantee and major disaster control

Embodiment Construction

[0041] Below in conjunction with example the present invention will be further described.

[0042]As a rock and soil stability monitoring device based on energy dissipation, the present invention mainly includes a temperature sensor, a telescopic spring, a fixed steel ring, a lead wire hole, a wire anti-pull device, a sealing water-stop strip, an anti-off device, a rubber belt, Insulating corks, wires, mortar bolts, lead wire steel gaskets, temperature data acquisition devices, bolt support plates and torque nuts, remote data processing and early warning devices. When installing the monitoring device, first set up the drilling hole, and slowly push the monitoring device into the drilling hole. During the pushing process, the anti-loosening device is subjected to axial outward force, compressing the rubber belt, so that the whole device can be pushed in. When the pushing is stopped, the outward force of the axial direction disappears, the rubber belt rebounds, and the jack-up a...

Abstract

The invention relates to an energy dissipation-based rock-soil stability monitoring device. The device comprises a temperature sensor, a telescopic spring, a fixed steel ring, a lead drilling hole, a lead pulling resistant device, a sealing water-stopping strip, a thread-off proof device, a rubber belt, an insulation wooden plug, a lead, a mortar anchor rod, a lead steel gasket, a temperature data acquisition device, an anchor rod support plate, a torque nut, and a remote data processing and early warning device. When the rock-soil is almost destroyed, the rock-soil is fast heated. The device can ensure that a temperature sensor is closely attached to the rock-soil, realize accurate measurement of rock-soil temperature change, determine whether the rock-soil is in a stable state through rock-soil temperature monitoring and data processing analysis according to the energy dissipation theory so that rock-soil deformation is early found and a deformation zone is determined, timely provide safety pre-warning and realize real-time monitoring and early warning of rock-soil stability.

Description

[0001] Technical field: [0002] The invention belongs to the field of geotechnical engineering monitoring, and in particular relates to a rock and soil mass stability monitoring device based on energy dissipation, which is suitable for monitoring and early warning of rock and soil engineering such as slopes and tunnels. [0003] technical background: [0004] The energy dissipation of rock and soil is one of the essential factors leading to engineering disasters. At present, conventional monitoring methods are mainly to monitor the deformation and displacement of rock and soil mass as an indirect indicator of energy dissipation, and use precision instruments to measure the external displacement and deformation of rock and soil mass, or use deep-buried sensors to monitor the internal deformation and displacement of rock and soil mass , and analyze the stability of rock and soil mass by monitoring the change and rate of change of displacement. The damage of rock and soil genera...
