Description

A kind of geotechnical stratified settlement measuring device
Technical field
The utility model designs a kind of rock of a kind of geotechnological measurement apparatus, specifically soil base, dykes and dams etc. application Native delaminating deposition measurement apparatus.
Background technology
Earth roadbed geological conditions, embankment load-up condition and execution conditions all have certain complexity, it is difficult to every Kind processing method carries out tight theory analysis, therefore can not just make accurate calculating in design, so can only often lead to The monitoring in work progress and the quality inspection after the completion of construction are crossed to ensure construction quality.The sedimentation detection that scene largely uses The main still monitoring to surface subsidence, such as infrared monitor, laser monitoring instrument of instrument.But these monitoring methods are still only The sum total measurement of sedimentation is rested on, the instrument and method that on-line measurement is settled specific to underground geotechnical stratified are considerably less.
Monitoring pair settled with geotechnical stratified, the measuring instrument of onsite application is mainly by sedimentation magnet ring, electromagnetism sense at present It should pop one's head in, survey the part such as chi composition.Sedimentation magnet ring is generally embedded in soil by the measuring principle of this electromagnetic type measuring instrument first, Then manual utilization surveys chi and down send electromagnetic inductive probe along sedimentation pipe, when electromagnetic inductive probe runs into sedimentation magnet ring Wait, system can send ring prompting, and then now scale surveys the registration and record of chi on hand for artificial naked-eye observation.So survey twice The registration measured can with calculate sedimentation magnet ring sedimentation deformation and sinking speed.
The shortcomings that this measuring method and deficiency are that measurement accuracy is not high, and Monitoring Data amount is considerably less, and artificial one Individual error of measured data is larger, and survey chi, signal cable line fatiguability fracture, and the larger cost of loss of mechanical structure is higher, can not Realize intelligent on-line monitoring.
At present also have a kind of measuring method, measuring principle is substantially similar with electromagnetic type sedimentometer, have a little unlike it With motor electromagnetic inductive probe is slowly sent to inside sedimentation pipe, and electromagnetic inductive probe monitoring switch state changes Signal is uploaded to terrestrial wireless receiving module using wireless communication mode, and motor is utilized when ground receives this signal Rotating speed and corresponding time relationship obtain the depth of sedimentation magnet ring decentralization.Although this monitoring method realizes does not need artificial meat Eye, which is read, surveys chi registration, but can not still break away from the loss of mechanization, and motor long-play also brings along larger rotating speed Error, accurate measurement can not be realized.And the phenomenon that data packetloss is necessarily had using wireless communication modes is occurred, data volume Less and intractability is larger, and this can cause the accuracy of measurement to substantially reduce.
Above two metering system, which can not all be realized, settles accurate measurement to geotechnical stratified, can not realize that intellectuality is online and survey Amount.
Utility model content
The purpose of this utility model be to solve current China is low to the automaticity of native settlement measurement, precision is not high, The problems such as real-time online measuring can not be realized, design propose a kind of measurement apparatus of geotechnical stratified settling height.
The technical solution adopted in the utility model is:
Device includes in-site measurement instrument and distant place measuring instrument, and both are communicated by wireless sensing and connected, wherein:
Described in-site measurement instrument mainly settles signal manifold by sedimentation magnet ring, geotechnical stratified and geotechnical stratified settles Signal gathering unit composition is settled, geotechnical stratified sedimentation sedimentation signal gathering unit is integrated by 1~n structure identical Hall Sensor string is formed by connecting, and all hell integrated sensors are each attached on mark post and are placed in sedimentation pipe, sedimentation magnet ring suit Outside sedimentation pipe, sedimentation pipe and sedimentation magnet ring are vertically arranged in the soil body together, and it is multiple heavy to be set with uniformly at intervals along sedimentation pipe Magnet ring drops;Spacing between per two adjacent hell integrated sensors is equal;Each hell integrated sensor passes through RS-485 buses are connected to geotechnical stratified sedimentation signal manifold, and signal manifold is settled to the integrated sensing of Hall by geotechnical stratified Device carries out Communication Control;

Described sedimentation magnet ring is annular permanent magnet structure.
Multiple hell integrated sensor array groups are settled into signal gathering unit into ground delaminating deposition, by sedimentation magnet ring point For cloth in the soil body, soil body sedimentation drives sedimentation magnet ring to follow sedimentation, and signal acquisition sensing unit ambient magnetic field strength can be caused to send out Change corresponding to raw, surrounding magnetic field power is detected by hell integrated sensor using Hall effect and is converted into electric signal, is adopted Electric signal is sent to geotechnical stratified sedimentation signal manifold, geotechnical stratified sedimentation signal in real time with RS-485 bus communication modes Manifold carries out data processing to electric signal.
Described geotechnical stratified sedimentation sedimentation signal gathering unit transmitting telecommunication number is transmitted with RS485 buses.This Kind transmission means is different from listens to the wireless sending module of ring prompting and underground to switching signal progress nothing using artificial ear Line sends both modes.This mode can both improve the reliability of data signal transmission, can ensure signal transmission again Promptness.
RS485 communication modes can be substantially the existing transmission of change accuracy and real-time.The survey at scene now It is to hear ring prompting using artificial ear to measure instrument first, and another is that the wireless sending module of underground enters to switching signal Row wireless transmission.The phenomenon of data packetloss occurs in this communication modes, inevitably results in the problem of data volume is inaccurate.And this Utility model is transmitted using RS485 buses to experimental data, efficiency of transmission is high, highly reliable, accuracy is larger and When property will get well more than wirelessly.
Described sedimentation magnet ring is annular permanent magnet structure.The utility model uses annular permanent magnet structure, compare with The particle Small Cylindrical set of permanent magnets of job site three has advantage simple in construction, installation operation is cheap into equilateral triangle at present, It can be very good to ensure the stability for settling magnet ring inside center point magnetic induction intensity;Even if it can ensure to settle magnet ring and sedimentation Relative torsion displacement occurs between pipe also will not produce any influence to the magnetic induction intensity of central point.
