The utility model relates to a kind of fluviograph that groundwater level changes of measuring, and particularly is installed in the geotechnical boring fluviograph probe that the groundwater level of quantitative test displacement rock, the soil body (it is as follows to be called for short gliding mass) changes.Technical field of the present utility model is the improvement to the float type level meter of measuring the groundwater level variation.
The prior art float type level meter, be partly to ooze the float in the underground water in boring with the end connection of indium steel wire, the other end connects weight, through placing the hell support pulley of dynamo-electric conversion metering system is housed, when groundwater level changed in the boring, pulley rose or descends with float and rotates.Mechatronic Systems on the pulley, a kind of is to produce Morie fringe with the optical system that is fixed on the pulley, with photoelectrometer recorded fringe variable number, reflects corresponding SEA LEVEL VARIATION situation.The Morie fringe that is produced is continuous, does not allow the Halfway Stopping photoelectric counting, and incompatible groundwater level in the gliding mass is changed carries out long term monitoring.Its advantage is the precision height, and the SEA LEVEL VARIATION value can measure 0.05 millimeter.Another kind is to reflect variation of groundwater level in the boring with the optical code disk that is fixed on the pulley, and also incompatible groundwater level in the gliding mass is changed of this optical code disk carries out long term monitoring.
Task of the present utility model is, carry out long term monitoring for adapting to groundwater level in the gliding mass changed, measure float type level meter that groundwater level changes and change a social system and make that its structure is simple more, low, the easy-operating gliding mass fluviograph probe that can carry out the automatic measurement WATER LEVEL CHANGES rule of long term monitoring in geotechnical boring at any time of cost existing.
Solution of the present utility model, be that the pulley that will have float type level meter now changes the different coaxial-type arbor wheel of size diameter into, one end of float connecting line and weight line is fixed and be wrapped in the physical dimension of dwindling fluviograph on the arbor wheel that places the diameter that varies in size on the support to different directions respectively, increase applicability.With different moment flood the meter starting sensitivity.With original dynamo-electric metering system that metering system changes contactor and series resistance coordinate composition into of changing, can carry out discontinuous measurement.With the remote control interface WATER LEVEL CHANGES of displacement rock, the soil body is carried out telemonitoring, be connected and monitor on the spot with general digital multimeter.
The utility model has following advantage with existing fluviograph ratio:
1. use the different coaxial-type arbor wheel of size diameter to become different moment, one end of float connecting line and weight line is fixed and is wrapped on the arbor wheel of the diameter that varies in size to different directions respectively, improved the starting sensitivity of fluviograph, reduced the space length of weight and float connecting line, increase applicability, dwindled the height of fluviograph.Use the metering system that contactor and series resistance coordinate are formed instead, the cost of instrument is reduced, structure is also simpler, and can with the telemonitoring device interface of full-automatic rock, land movement, directly phreatic water level variable in the gliding mass is become electric parameter and carry out telemonitoring, and can round-the-clock, long term monitoring, can be connected on the spot with general digital multimeter again and monitor, easy to use, easy operating.
2. but the Changing Pattern of water level value in the utility model quantitative assay gliding mass is analyzed the correlation between water level and the gliding mass activity, and analysis of slope stability is played an important role, and is one of important tool of research gliding mass.Precision: ± 2 centimetres, ranging: 2.5 meters.
3. wriggle in the utility model and the dual-purpose gliding mass, the intrinsic displacement test probe, dual-purpose gliding mass settlement gauge, dual-purpose auto thermal compensation ductilimeter, dual-purpose gliding mass high-precision deformation meter, six kinds of rocks such as gliding mass overload alarm probe, the land movement tester is used in combination, rock applicable to various scales, land movement, can fully understand rock, the pace interval rule of land movement, can be to the displacement rock, the stability of the soil body, growth trend can mobile scale, sliding speed, the slide plane degree of depth, slide surface forms situation, the extent of injury, facing sliding time etc. provides data information.The threat whether mountain area major workss such as the railway in can planning to build country, mine, reservoir, factory are subjected to rock, land movement provides reliable data information.Finish feasibility study more easily, reduce the huge disastrous effect that disastrous engineering geological problems brings.Can carry out monitoring, alarming to existing cities and towns, factory, mine, railway, highway, dam and the Other Engineering building etc. that threatened by rock, land movement.
4. wriggle in the utility model and the dual-purpose gliding mass, the intrinsic displacement test probe, dual-purpose gliding mass settlement gauge, dual-purpose auto thermal compensation ductilimeter, dual-purpose gliding mass high-precision deformation meter, six kinds of gliding mass test probe combinations such as gliding mass overload alarm probe and full-automatic rock, the field data sampling of monitoring of soil displacement, coding, the conveyor apparatus interface, by full-automatic rock, the center control of monitoring of soil displacement, decoding and universal interfacing instrument are controlled and are formed full-automatic rock, the monitoring of soil displacement system, can be at the distance rock, land movement is on-the-spot more than 50 kilometers, even hundreds of kilometer, thousands of kilometers indoor, can collect the rock of surveying at any time, the Various types of data of land movement, do not need the people to change and handle fully, and automatically data are imported computer rock by machine, each data of land movement activity are calculated automatically and are printed.
