Description

A kind of laser datum point detection device monitored based on reservoir dam

Technical field

The utility model is related to a kind of reservoir dam monitoring device, specifically a kind of based on swashing that reservoir dam is monitored Light Trigger jitter detection device.

Background technology

Concrete dam and stone masonry dam are built up after retaining utilization, in the effect such as water, silt, wave, uplift pressure, temperature and earthquake Under, necessarily deform, seriously cause to subside, case is too numerous to enumerate.Dam safety monitoring technology is international concern problem.

Dam structure safety monitoring system is related to multiple ambits such as optics, sensor, electronics, two ranks of development experience Section：

1st, stage (1891～1964 years), also referred to as prototype measurement are observed.Because the level monitoring in the stage is relatively low, simply right The monitoring instrument being placed on dam structure carries out manual observation and detection, records dam real-time status.

2nd, the stage (nineteen sixty-five is so far) of security viewpoint direction finding safety monitoring transformation and development.Gradually anticipate in domestic external monitor field Know the limitation of instrument detection, just dam is adopted and is manually patrolled in combination with Instrument observation.Wherein Japan, the U.S. are earliest The country of walkaround inspection is carried out, also all regulation must be carried out to dam for the country such as subsequently French, Canada of Italy and Norway Manual inspection, so as to effectively avoid the defect for only carrying out safety monitoring to dam with observation instrument.But due to artificial inspection The change on dam surface can only be observed, and the labyrinth change and potential safety hazard to its inside is difficult to distinguish, it is therefore necessary to A kind of monitoring technology that can at any time, everywhere, in time, efficiently reflect and detect dam safety issuess of utility model.The sixties Later stage, external many countries are studied and are manufactured to the instrument and equipment of monitoring dam safety automatically：Japan realizes first Automatic data collection is carried out to Monitoring Data on arch dam；Afterwards, Italy successively realizes plumb instrument deformation auto-monitoring and centralized Gathered data system；1989, Canada be possible to carry out data acquisition, storage, processs, it is long-range and analyze etc. function oneself Dynamicization detecting system is arranged on dam.China starts to carry out monitoring to dam deformation from the eighties, also have developed distributed intelligence Detection data acquisition system, wireless communication module and the software systems of dam network safety information can be safeguarded.

At present dam deformation is monitored in the world and adopt two ways：

1st, according to basic point elevation and position, using theodolite, spirit level, electronic distance meter or laser collimator, GPS, intelligence Can total powerstation etc. measuring elevation and change in location at dam body surface monument, surveyor's beacon.The three-D displacement data of achievable measuring point are surveyed Amount；

2nd, the instrument of some monitoring displacements is installed or buried on dam body surface, is typically only capable to measure the individual event displacement number of measuring point According to (horizontal displacement or vertical displacement).Conventional displacement monitoring instrument has displacement meter, crack gauge, dipmeter, sedimentometer, vertical line to sit Mark instrument, tensile-line instrument, multipoint displacement meter and strain gauge etc..

For deformation monitoring equipment, from the perspective of from several respects such as precision, stability, installing engineering amount, maintenance, prices, can be full The equipment of sufficient requirements does not almost have.Dam body internal displacement monitoring can only use traditional individual event displacement monitoring equipment, need Pre-plugged or drilling is wanted to install, construction inconvenience, the alternative that there is presently no；Three dimensions that dam body surface displacement is used According to monitoring device is easy for installation, stable performance, high precision, but affected greatly by geographical environment, mounting condition is restricted, and cost It is high.
