Further, described tinsel is steel wire or copper wire.
Compared with prior art, a kind of novel measurement landslide sliding surface position of the present invention and the method and apparatus of slippage, it can have tens measuring points even more a plurality of measuring point, and range is big, the precision height, it can determine the position and the slippage of slipping plane more accurately.Simultaneously, the data of sliding surface slippage can be transferred to data processing centre (DPC) in real time, and the slippage data are carried out intellectuality processing and demonstration.The present invention is because tinsel such as steel wire or copper wire in this device are thinner, and is can point arranged much more many than the multipoint displacement meter of using always, so just can determine the size of slippage on the position of slipping plane and the slipping plane more accurately.In addition, owing to adopted high-precision duplex angular displacement sensor, the range of measurement is unrestricted, and the precision height.Simultaneously, by radio transmitting device can also be in real time with the data transmission of sliding surface slippage to deep slippage Monitoring and Controlling administrative center, and deal with.
Description of drawings
Fig. 1 is a kind of structural representation of measuring the device of landslide sliding surface position and slippage of the present invention.
Embodiment
Specify the present invention below in conjunction with accompanying drawing:
Among Fig. 1, the ground 15 of region to be measured is provided with sensor measurement platform 6, and ground vertically has a boring 16 for 15 times.Wireless data transmission device 12, accumulator 13, solar panel 14, several supports 3 (only showing 2 supports among the figure) are installed on the sensor measurement platform 6, have a runner 2 on each support 3, angular displacement sensor 1 is installed in the center of runner 2, all angular displacement sensors 1 are installed in the rain cover 7 and all link to each other with wireless data transmission device 12, and solar panel 14 and accumulator 13 are angular displacement sensor 1 and wireless data transmission device 12 power supplies.16 internal fixation of holing are equipped with sleeve pipe 17; be set with a metal tube 11 in the sleeve pipe 17; the end that some (only illustrating 2 among the figure) has the steel wire 4 of protective sleeve (not shown) is fixed on different depth place on the outer wall of metal tube 11 by rivet 10 respectively; the other end of steel wire 4 is fixed on the steel wire clamp device 5 after walking around the excircle of the runner 2 on each self-corresponding support 3, and steel wire clamp device 5 is fixed on the sensor measurement platform 6.Be cast with sand-cement slurry 8 between sleeve pipe 17 and the metal tube 11 and be used for fixing the protective sleeve and the metal tube 11 of steel wire 4.Angular displacement sensor 1 is the conductive plastics angular displacement sensor or the angular encoder of duplex.
When the landslide geologic hazard occurring, the geological stratification generation slippage of ground below 15, sleeve pipe 17 and metal tube 11 are cut off in slippage place, and steel wire 4 has flexibility can not cut off, and and then glide plane one starting, because steel wire 4, will drive runner 2 in the motion of glide plane and rotate, angular displacement sensor 1 will in time be failed this variation numerical value and be transferred to landslide depth slippage Monitoring and Controlling administrative centers by wireless data transmission device 12.When angular displacement sensor 1 is measured a certain position and following point and all displacement occurred, the a certain position that just can judge between the point of this point and this some top is a slipping plane 9, and calculate the slippage of slipping plane 9 according to the numerical value change of angular displacement sensor 1, can determine the position and the slippage of slipping plane 9 relatively accurately.
