Node monitoring device and method for active protective net

Abstract

The invention discloses a node monitoring device and method for an active protective net, and the device comprises dynamometers, displacement meters, joints, clamps and bolts, the dynamometers are located at the left and right sides of a node of the active protective net and are symmetrically arranged on a transverse supporting rope, and the displacement meters are located at the upper side of the node of the active protective net and are arranged on a longitudinal supporting rope; the system monitoring device composed of the dynamometer, the displacement meter and other sensors is adopted, the active protective net nodes can be monitored in real time, the monitoring precision is high, the reliability is good, and early warning, forecasting and risk management and control of the landslide can be achieved.

Description

technical field [0001] The invention relates to a node monitoring device and method of an active protection network. Background technique [0002] As a common slope protection structure, the active protection net is widely used in engineering construction fields such as slopes. Its working principle is mainly through the combination of criss-crossing horizontal support ropes and longitudinal support ropes and steel cable anchors arranged in a square pattern. Connect and carry out pre-tensioning. A cable net is laid in each hanging net unit composed of supporting ropes. The protective net system applies a certain normal preload to the slope, thereby improving the stability of the surface rock and soil, preventing the occurrence of landslides as much as possible or limiting the damage of local rock and soil, and achieving the safe operation of the expressway. Purpose. However, during the actual operation of the expressway, under the combination of a series of unfavorable eff...

Problems solved by technology

However, during the actual operation of the expressway, under the combination of a series of unfavorable effects such as plum rains and typhoons, the high slope body is subject to obvious weathering and erosion, and the weathering of the rock mass on the slope surface is intensified, which is prone to disasters such as collapse and collapse. After the collapse or collapse occurs, it will cause certain damage to the active protection network, thereby causing certain hidden dangers to the safe operation of the expressway, and after the collapse or collapse occurs, because there are no monitoring measures, the hidden danger cannot be discovered in time, resulting in a large Loss
