Technical field
The present invention relates to a kind of measuring equipments of scour depth, more particularly, to a kind of experiment of wave current sink bench model
Local scouring depth measurement instrument.
Background technology
The problem of science of bridge building plays increasingly important role in modern social economy, but bridge disaster by flood is brought
Thereupon, especially in the bridge in mountain area, river entrance region, due to complicated hydrogeological conditions, souring is more
To be apparent, bridge disaster by flood accident happens occasionally, and how preferably to solve the problems, such as that the local scour of bridge becomes a significant task.
Domestic and foreign scholars carry out in wave current sink the research for the problem of washing away often through model test, and scour depth is as examination
The key data tested, measurement method become a relatively difficult task.
In model test, since the Scouring Characteristic of small-medium size structure is complicated, it is desirable that instrument takes up space small, measures smart
Degree is high, and test operation is good, still lacks suitable measurement equipment at present.Or some in situ measurement means in Practical Project are required
Space is big, can not directly dispose use, as sounding system, heavy 15kg, important component energy converter ruler are swept in TSR-3000 three-dimensionals side
Very little is 330mm × 70mm × 42mm, size ratio test model and washes away and is formed by hole bigger, can not be made in laboratory again
With；Measurement accuracy cannot meet Laboratory Request, such as：The portable sounding instruments of SonarMite, precision are ± 0.1% water of 1cm
It is deep, it is unable to reach the measuring accuracy of the 0.1mm required in experiment.And some can meet the experimental facilities price mistake of required precision
In costliness, such as the hundreds thousand of quotations easily of some underwater three dimensional terrain instrument, common laboratory can not be born.These test equipments by
The constraint of its test philosophy, mode is single, and precision cannot be satisfied Laboratory Request, cannot need to be adjusted according to experiment, and
Single-point can only often be measured, complicated for operation, high cost and inefficiency, therefore develop easy laboratory test test
Equipment pole it is necessary to.
Preferably to be measured to test result, propose that a kind of test probe of scour depth, wherein key technology are
Meet flexibility and the test accuracy of instrument, it is different to be related to content about the patent of scour survey and this patent at present, arranges such as
Under：1. a kind of Water-related Project local scour monitoring system and method (CN103901433A) based on ultrasound induction, this method are
Water-related Project scene is realized using computer to engineering local scour by the method for measurement of local scour based on sonication
Monitoring；2. a kind of test apparatus (CN102374958B) for the research of seepage through soil mass Scouring Characteristic, this method be it is a kind of about
The instrument of seepage through soil mass Scouring Characteristic, study subject are seepage scour mechanism；3. a kind of local scour near pier observation system
(CN102087360B), this method is observed local scour around bridge pier with ultrasonic probe, it is preferred that emphasis is is rushed to bridge pier
Water flow structure and underwater topography during brush carry out field observation；4. a kind of underground silt-scrubbing model experiment device and method
(CN101666720B), it is a kind of method being related to silt underwashing experiment, be substantially carried out underground sediment washes away observation.Above-mentioned hair
Bright patent is not directed to the measurement content of the local scouring depth and range of small scale experiment in wave current sink chamber, and mentioned shows
Field test method cannot be satisfied the operating condition and precision in laboratory, and used sonication can not be tested shallow water indoors
Under the conditions of carry out.
