Description
Technical field
The utility model relates to a kind of reservoir dam pick-up unit, specifically reservoir dam depression and horizontal shift reference point pick-up unit.
Background technology
Dam is as the crucial multi-purpose project of great hydraulic engineering, whether its stability and safety is directly connected to other ancillary works of whole hydraulic engineering is normally moved, and directly affect and determine to focus on the security of large hydraulic engineering integral body and the performance of design efficiency, the more important thing is its stability and the safe direct relation downstream area people's the security of the lives and property, social and economic construction and ecological environment security etc.
Concrete dam and stone masonry dam build up after water conservation reservoir utilization, and under the effects such as water pressure, silt pressute, unrestrained pressure, uplift pressure and temperature variation, dam body must deform.The variation of the distortion of dam body and various load action and influence factor has corresponding regular variation, and within the range of permission, this is normal phenomenon.Yet the abnormal deformation of dam body is the tendency of dam malicious event often.Before the accident of nineteen fifty-nine France Ma Erbasai arch dam, having there is abnormal deformation in abut, if this dam has carried out the deformation observation of system at run duration, grasps in time the deformation of abut, adopts an effective measure, and is likely to avoid the accident that breaks down.Therefore, for guaranteeing the safe operation of concrete dam and stone masonry dam, must carry out deformation observation to dam body, whether normal to grasp at any time dam distortion under various load actions and related factors impact.Concrete dam and stone masonry dam are subject to be subject to uplift pressure effect upwards at the bottom of the thrust of the horizontal directions such as water pressure and dam, have the trend of sliding downstream and toppling, and therefore will carry out horizontal displacement observation.Concrete and stone-laying all belong to elastic body, and under horizontal loads, amount of deflection will occur dam body, therefore also need to carry out deflection observation., will there is volume change in the load actions such as dam body temperature influence and deadweight, depression also will occur ground, need to carry out perpendicular displacement (depression) observation.China arranges monitoring system since the eighties in 20th century on a large scale at dam.
The classification method of dam body displacement monitoring has: 1) according to the position of measuring point, be divided into dam body surface and internal displacement monitoring; 2), according to measurement function, be divided into horizontal displacement monitoring, perpendicular displacement monitoring and three-D displacement monitoring; 3), according to the continuity of monitoring, be divided into artificial cycle monitoring and on-line continuous monitoring.Dam body surface displacement monitoring method comprises two large classes: 1) according to basic point elevation and position, with transit, spirit-leveling instrument, electronic distance measuring instrument or laser collimator, GPS, intelligent total powerstation etc., measure dam body surface monument, surveyor's beacon place elevation and change in location, this mode can realize the three-D displacement DATA REASONING of measuring point; 2) on dam body surface, install or bury underground the instrument of some displacement monitorings, this mode can only be measured the individual event displacement data of measuring point conventionally.Dam body internal displacement monitoring is mainly realized by embedded instrument is installed, and conventionally can only monitor the individual event displacement data (horizontal shift or perpendicular displacement) of measuring point.Conventional displacement monitoring instrument has displacement meter, crack gauge, inclinator, sedimentometer, plumb line coordinator, tensile-line instrument, multipoint displacement meter and strainometer etc.
Online detection research situation is as follows both at home and abroad at present.
1, horizontal shift on-line monitoring technique
Supporting layout and checking are mutually carried out in dam body horizontal displacement monitoring technology and surface deformation monitoring, dam body perpendicular displacement monitoring etc.Common technology has tiltmeter technology, draws bracing cable technology, just, reversed pendulum technology etc.
1.1 tiltmeter technology
Tiltmeter technology is mainly used in measuring the displacement of dam body inner horizontal, and principle of work is the variable angle amount of measuring between inclinometer pipe axis and pedal line, thereby calculates the horizontal shift size of soil layer each point.Tiltmeter have movable tiltmeter and fixedly tiltmeter minute.Movable tiltmeter is for manual measurement, and fixedly tiltmeter can be realized automatic on-line measurement.Its measuring method forms sensor string at a certain distance by some stationary slope levels, calculates the inclinometer pipe section that each sensor is corresponding move according to transducer spacing (gauge length) and measured inclination angle, forms the horizontal distortion curve of inclinometer pipe.Different according to sensor, fixedly tiltmeter is divided into servo accelerometer formula, electrolyte type, resistance-strain chip etc.That the method construction is disturbed is less, measuring principle theoretical foundation fully, stable performance, simple to operate, can on-line monitoring.When measurement hole depth is little, measuring accuracy meets the demands; But when hole depth is larger, inner laying sensor is more, and cost is higher, and measuring accuracy is affected simultaneously.
1.2 draw bracing cable technology
Drawing bracing cable formula horizontal displacement meter is to utilize the stainless steel steel wire that linear expansion coefficient is very little that the horizontal shift of dam body internal monitoring point is delivered to the observation room outside dam, by measuring steel wire, the fixing relative displacement of punctuate is realized the observation of dam body inner horizontal displacement.By leading block, at its observation room end, add fixedly counterweight or a weight, when the flat measuring point of water in dam moves, drive steel wire moves, and in the fixing displacement of punctuate place steel wire, adds that the displacement of self is the displacement of the flat measuring point of water in dam.The method measurement result reproducible, precision is high, and measurement result is not subject to the such environmental effects such as atmospheric pressure and temperature, do not need to carry out atmospheric pressure compensation and temperature correction, long-time stability are good.But the method construction is complicated, maintenance inconvenience.Drawing bracing cable technology also can be for the displacement of monitoring dam body surface level, and principle is to adopt a stainless steel steel wire to apply tension force at two-end-point place, thereby makes its straight line that is projected as at surface level measure measured point with respect to the offset distance of this straight line.With collimation line method, compare, the datum line of this method is the straight line of a physics.The feature of method of tension wire alignment is: be subject to ectocine little, in dam monitoring, application is general.Its measuring accuracy depends primarily on reading accuracy, adopts the bracing cable measuring system of drawing of linear CCD sensor to realize automatic reading, and its range is several centimetres, be better than ± 0.1mm of precision.But the two ends of drawing bracing cable generally will be provided with vertical line, so that the benchmark of measurement to be provided, objectively increased the installation and maintenance use cost of system.The development trend of drawing bracing cable technology is two-way lead wire, and the displacement of the gentle vertical direction of observation water, has improved observation rate simultaneously.
1.3 just, reversed pendulum technology
Just, reversed pendulum both can realize dam body surface level displacement monitoring, can realize again the deflection observation of earth dam.Meanwhile, the method again often and other method such as method of laser alignment, method of tension wire alignment be used in conjunction with.Vertical frontal line is that one end is fixed near dam crest, and the other end hangs weight, so as between observation dam body each point and dam body with respect to the displacement of the dam foundation, and the deflection observation of dam body.Reversed pendulum is that one end is embedded in dam body foundation deep layer basement rock place, and the other end floats, and measures the absolute displacement of dam body.This technology is widely used in dam monitoring, and attains full development, and adopts linear CCD sensor technology can realize automatic reading.
2 dam body perpendicular displacement on-line monitoring techniques
Dam body perpendicular displacement monitoring and dimensional deformation monitoring, dam body horizontal displacement monitoring etc. are carried out supporting layout and checking mutually.Main monitoring method has communicating pipe method monitoring technology (static level method), horizontal stationary slope level monitoring technology, vibrating wire settlement sensor monitoring technology etc.
2.1 communicating pipe method on-line monitoring technique
Utilize liquid communicating pipe two-port in the principle of same level, observe, the implementation of dam body internal vertical displacement monitoring is: in dam body, design monitoring position arranges sedimentation gauge head, in gauge head, settle a container, be furnished with water inlet pipe, drainpipe and gas outlet, three Guan Shunpo guide to dam body outward appearance ell, water inlet pipe is connected with measurement mechanism (marking graduated glass tube) in observation room, by connection balance, makes in glass tube the vessel level in liquid level and gauge head in same water level elevation.Drainpipe is the unnecessary liquid discharge that limits water level by surpassing in gauge head container, and fixedly water level in gauge head container, can calculate gauge head elevation by the glass tube water level on observation room measurement mechanism.Gas outlet communicates container with observation room atmosphere, make liquid level in container be identical atmospheric free surface with liquid level in glass tube.The method measuring principle is simple, intuitive measurement results.By water colunm height in the high sensor measurement glass tube of measuring accuracy, can realize on-line monitoring.But also have following shortcoming: civil engineering workload is large, the concreting of measuring point pier needs curing time, and channel excavation affects construction transportation, and construction is disturbed large, affects main body construction progress; Construction process requirement is higher, need carry out necessary protection to gauge head and pipeline, and pipeline must reliably connect; Liquid is had to specific (special) requirements, need to adopt the distilled water of exhaust, at cold district, need add anti freezing solution; In pipe, the existence of the suitable microorganism of environment, certainly leads to and affects the material that pipeline is unimpeded, causes measuring system to lose efficacy; Observation program and maintenance measure are complicated.Hydrostatic level is also the important instrument of monitoring dam body surface vertical sedimentation, and measuring principle is identical with connecting pipe principle, according to the elevation of starting datum mark, by the discrepancy in elevation recording communicating pipe, carrys out the elevation of pilot measurement punctuate.Communicating pipe is comprised of sebific duct, glass tube and delineation chi etc.This method is not subject to the impact of Atmosphere Refraction, is easy to realize the robotization of reading and transmission, and be better than ± 0.1mm of measuring accuracy is widely used in perpendicular displacement monitoring.Hydrostatic level is reliable because measuring high, the long-term Measurement sensibility of precision prescribed, with the measurement of general small-range pressure transducer, does not reach this requirement.
2.2 horizontal stationary slope level monitoring technology
On design monitoring elevation, level is laid inclinometer pipe, in pipe, place the sensor string being formed at a certain distance by some horizontal stationary slope levels, adopt the fixedly inclination angle of gradient meter sensor measurement vertical direction, according to transducer spacing (gauge length) and measured inclination angle, calculate the inclinometer pipe section that this sensor is corresponding and move, the deformation curve that the algebraic sum that each sensor respective tube section moves forms is the sedimentation and deformation curve of inclinometer pipe.The method construction is disturbed less, quick and easy for installation, and measuring principle theoretical foundation is abundant, and the construction time can be observed, do not need auxiliary civil engineering, easily realize on-line monitoring, sensor resolution is high, measuring accuracy meets the demands, and observed result is subsidence curve, meets dam deformation rule.But measurement range is little, easily there is uneven settlement or dislocation, larger on measuring system impact, whether adapt to large sedimentation and deformation and need further to study and verify.
2.3 vibrating wire settlement sensor monitoring technology
Vibrating wire settlement sensor is fixed on sedimentation plate, by fluid-through tube, distilled water (anti freezing solution) is input to sedimentometer, form distilled water (anti freezing solution) water column, the pressure that water column produces acts directly on the pressure-bearing mould of sensor, change calculations by survey sensor frequency goes out change value of pressure, can know the height of water column through converting by inference.Measure water column liquid level elevation, can calculated settlement dish elevation.The method measuring principle is simple, and more for convenience, the construction time can be observed, and can realize on-line monitoring in construction.But have line clogging and antifreeze problem, if water colunm height is too high, measuring accuracy does not reach code requirement.Absolute settlement accuracy of observation is subject to measurement of the level Accuracy.
3 three-D displacement on-line monitoring techniques
Above-mentioned various monitoring method is to the horizontal shift of deformation point and perpendicular displacement testing respectively, affects measuring accuracy, increases difficulty of construction and workload, and measurement data simultaneity is bad.Development along with surveying instrument and measuring technique, adopt in a large number at present the measuring technique of the observation dam body surface deformation point horizontal shift of energy real-time continuous and perpendicular displacement, due to what measure, it is the three-D displacement value of deformation point, therefore be called " three-D displacement monitoring ", major technique has high-precision intelligent total station instrument technique and GPS monitoring technology etc.
3.1 intelligent total station instrument techniques
Intelligence total station instrument technique, utilize exactly so-called robot measurement (MeasurementRobot, the Huo Cheng geodetic Geo-robot of robot) carry out automatic search, tracking, identification and accurately find target accurately and obtain the information such as angle, distance, three-dimensional coordinate and image.Utilize intelligent total powerstation to carry out the robotization deformation monitoring of tailing dam, the monitoring form of generally taking is: the DEFORMATION MONITORING SYSTEM that intelligent total powerstation and monitoring point target (sighting prism) and upper control computer form, can realize round-the-clock unattended surveillance, its essence is automatic Polar measuring system.System, without manual intervention, can automatically gather, transmit and the three-dimensional data of processing deformation point.Utilize the Internet or other LAN (Local Area Network), also can realize remote monitoring and administration.The deployment cost of which monitoring point is low, management maintenance is easy, monitoring accuracy is high, and monitoring distance accuracy can reach 1mm left and right.But shortcoming is system lays the impact that is subject to the conditions such as landform, weather, can not realize intervisibility completely and measure, and compares with traditional measurement method, and early stage, installation cost was relatively high.
3.2 GPS robotization technology for deformation monitoring
In the mounted on-line monitoring system of China, dam facing displacement measurement much all adopts GPS automatic monitoring technical.GPS automatic monitoring technical and full-automatic total powerstation automatic monitoring technical are all by the contrast of dam facing monitoring point and basic point relative position, determine the displacement of monitoring point.But the monitoring accuracy of single GPS equipment can not meet the technical requirement of tailing dam safety management, need by GPS real time differential DEFORMATION MONITORING SYSTEM, utilize the deformation contrast of each monitoring point and base station, can greatly improve displacement monitoring precision, GPS displacement monitoring precision can reach horizontal shift 3mm, perpendicular displacement 5mm.Applying GPS carries out tailing dam deformation monitoring and has lot of advantages: 1) between survey station without intervisibility; 2) can put forward the three-D displacement information of controlling/monitoring point simultaneously; 3) round-the-clock monitoring; 4) monitoring accuracy is high; 5) easy and simple to handle, be easy to realize monitoring automation.But GPS also has its weak point: limited by satellite situation.For example, requiring between gps antenna and gps satellite must intervisibility, and any blocking all reducing available number of satellite, affects measuring accuracy.2) be subject to sky environmental impact.At noon on daytime, be subject to ionospheric interference large.Share satellite number few, often do not receive 5 satellites, thereby initialization time is long, even can not initialization, also just cannot measure.3) Data-Link transmission be disturbed and restriction, operating radius less than nominal range.While there is above-mentioned situation, measuring accuracy does not reach nominal accuracy, cannot meet measurement requirement.
At present, China's dam safety monitoring field all approaches or reaches advanced world standards at aspects such as monitoring instrument and automatic data acquisition system development and the researchs of Data Management Analysis method, and the various on-line monitoring instruments that are applied to reservoir dam are of a great variety.Yet for many years, China's reservoir dam displacement monitoring is in personal monitoring's stage, on-line monitoring just just just developed in recent years.With regard to displacement monitoring equipment itself, although kind is a lot, every kind of equipment has its weak point, from several respects such as precision, stability, installation work amount, maintenance, use, prices, investigates, and can meet the equipment of requirements seldom.Dam body internal displacement monitoring can only be used traditional individual event displacement monitoring equipment, needs pre-plugged or boring to install, and construction inconvenience, does not also have good alternative method at present; Three-dimensional data monitoring equipment that dam body surface displacement is used is easy for installation, stable performance, precision are high, but affected greatly by geographical environment, and mounting condition is restricted, and this type of home-made equipment rate is low, installation cost is high.
