The sensor is respectively positioned at the center of rotating wheel on the corresponding brackets. One end of a plurality of wires is respectively positioned at the different locations on the exterior wall of the straight pipe along with the axes of the straight line, while the other end of the wire is respectively reeled around the rotating wheel on the corresponding brackets and then connected. The utility model has decades of measuring points and even more measuring points with large measuring range and high precision, which can be more accurately measure the location and sliding amount of slide surface. At the same time, the data of the sliding amount of slide surface can be promptly transmitted to the data treatment center and can be intelligently treated and displayed.
Description
Technical field
The utility model relates to geologic hazard monitoring and forecast field, particularly a kind of device of measuring landslide sliding surface position and slippage.
Background technology
In the monitoring and prediction of landslide disaster, the slippage of determining position of slip surface and slipping plane is very important.Now, people monitor side slope deep deformation and displacement with multipoint displacement meter, it is a kind of effective measurement means, after it utilizes and holes in rock soil mass, different depth is buried fixedly anchor head of measuring point underground in the hole, the measuring staff that is connected with anchor head (measuring staff external application pillar and Grouting Cement mortar separate) is gone up installing displacement readings device, measures along the measuring point displacement of the different depth on the drilling axis by the displacement readings device to change.But existing multipoint displacement meter is general maximum can install 6 anchor heads at different depth, the distortion in a plurality of slipping planes of monitoring different depth and zone, and also range is limited.
The utility model content
At the deficiencies in the prior art, the purpose of this utility model provides the device of a kind of range is big, measuring accuracy is high measurement landslide sliding surface position and slippage.
For achieving the above object, a kind of device of measuring landslide sliding surface position and slippage of the utility model, comprise a straight tube, some have the tinsel of protective sleeve, the angular displacement sensor identical with tinsel quantity and with the supporting support of sensor, support has runner; Sensor is separately fixed in the runner of corresponding support in the heart, one end of some one metal wires is separately fixed at the diverse location place on the outer wall of straight tube along the axis of described straight tube, the other end wiry is fixed after walking around runner on the corresponding support respectively.
Further, also comprise a sleeve pipe that is complementary with described straight tube, described straight tube and tinsel all are arranged in the sleeve pipe.
Further, also comprise wireless data transmission device, described sensor all links to each other with this wireless data transmission device.
Further, also comprise accumulator and solar panel, this accumulator links to each other with described wireless data transmission device with described sensor with solar panel.
Further, described angular displacement sensor is the conductive plastics angular displacement sensor or the angular encoder of duplex.
Further, described straight tube is metal tube or pvc pipe.
Further, described tinsel is steel wire or copper wire.
Compared with prior art, a kind of novel measurement landslide sliding surface position of the utility model and the device 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 utility model 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 utility model.
Embodiment
Specify the utility model 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 straight pipe 11 in the sleeve pipe 17; the end that some (only showing 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 straight pipe 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 straight pipe 11 and be used for fixing the protective sleeve and the metal straight pipe 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 straight pipe 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.
The purpose that protective sleeve is set outside steel wire 4 is for cement mortar and steel wire 4 being separated, steel wire 4 being slided in protective sleeve smoothly.In addition, steel wire 4 can also replace with tinsels such as copper wires, also can be with the stronger nylon wire of toughness etc., and metal straight pipe 11 can also replace with the PVC straight tube.
The utility model is because steel wire 4 is 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 9 and the slipping plane 9 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 wireless data transmission device 12 can also be in real time with the data transmission of sliding surface 9 slippages to deep slippage Monitoring and Controlling administrative center, and handle it, and the slippage data carried out intellectuality handled and demonstration.
