Description
Technical field
The present invention relates to navigation channels to observe field, the sound collection observed in more particularly to a kind of river for the defeated shifting of boulder and cobble
System, harvester and its method for arranging.
Background technology
After Impoundment of Three Gorges Reservoir operation, reservoir area channel condition is greatly improved, but still cannot adapt to navigate at this stage completely
Fortune development.Think that Fluctuating Backwater Area shoal hinders boat mainly by boulder and cobble according to channel silt Prototype Observation and Analysis work for many years
Scour and Accretion causes, and at present because being limited by observation device and observation technology, it can not effectively obtain the defeated shifting of prototype boulder and cobble
Real time kinematics characteristic, therefore Fluctuating Backwater Area pebble shoal scour-silting rule is recognized still not very clear.
Domestic and international bed load sediment testing method, which sums up, at present can be divided into two classes：Direct test method and indirectly test
Method.Direct test method is mainly the sampler and device by means of various sizes and structure, directly measures the side of bed load sand-like
Method.The direct method of measurement divides device to survey method and hole survey method.It is to put bed load sampler to riverbed directly to measure bed load sand that device, which surveys method,
Ocean, sampling process is convenient, flexible, intuitive, and the river condition and flow and sediment of adaptation are wider compared with other methods, can measure and push away
The cross direction profiles of matter silt discharge and section passage rate are moved, when survey time can control passage silt discharge change procedure, it can be deduced that certain
The moon, year passage amount and the various features value of one survey station.Disadvantage is that：First, test workload is too big；2nd, sampler is not
Enough perfect, some sampler samples are less efficient or even there are no available sampling efficiencies；3rd, sampler blocks water larger,
Under the conditions of flood in the presence of cannot transfer to river bed the phenomenon that, influence the normal collection of big silt discharge data.It cheats in survey method
It is easier that fixed hole survey method sets hole on withered riverbed, and does not need to the calculating corrected into line efficiency, but this method can only be
River or gully use；Total passage amount after a flood can only be obtained, it is impossible to measure the change procedure of passage amount；Slot hole method is surveyed
Precision height is tested, but is generally only used for river channel, and equipment bulky complex, it is costly.Indirect test method is with using various physics
Based on principle or by testing and the relevant physical quantity of Bed Load Movement, Sediment Transport amount is calculated indirectly.Wherein bed ripples method
Disturbance of the method to riverbed can be surveyed to avoid device, but it is mainly used for sandy riverbed, it is more difficult for the Changjiang river the Measurement of Bed Load；Difference is surveyed
Method is only applicable to the sand bed-load test of brook or river；Volumetric method cannot measure the continuous process of bed load discharge, only
It can obtain total passage amount of a certain period；Lithology investigation method, can be in a short time in the case where lacking actual measurement bed load data
The passage quality in each tributary in riverbed is extrapolated relatively according to field lithology survey data to measure, but this method heavy workload can only be big
Cause reaction average case for many years, it is impossible to react bed load change procedure, simultaneously as the abrasion of lithology cobble when investigation section compared with
Length has larger impact to test result precision；Trace method floats sand and diffusion velocity according to tracer etc. to study in research seashore
Sedimentary loading of sand bed-load etc. obtains reliably achievement, but the Large River as the Changjiang river face to face, due to cobble particle phase
Mutual burial effect, missing particle is difficult to recycle, in addition, also there are environmental pollution problems for radioactive isotope, it is impossible to as routine
Observation procedure；Photometry in flash spotting is since the shape of bed load sediment particle and the turbidity of flow are to photometer electricity pulse amplitude
The influence of value is too big and is the impact for avoiding sediment movement, it is necessary to the factors such as reliable protection, the party are carried out to optical element
Method is restricted；Underwater camera method is only applicable to silt content very little, river water compared with the river clear, the depth of water is shallower, sand grain is larger,
And necessary protection must be carried out to instrument and equipment and effective illumination measures must be taken；Ultrasonic is differentiated
Rate, timeliness, flow condition and silt content etc. are affected, and observing buoy is difficult to reach requirement.ADCP mensurations use ADCP
Technology while flow velocity is measured, using the movement velocity of synchronized tracking and backscattering functional measurement bed load, is pushed away with this
Bed load discharge is calculated, which is the Measurement of Bed Load new technology to grow up in recent years, is still in conceptual phase at present.Sound
Method is in bulky grain silt（Cobble or gravel）During because of movement, acoustic sensor and recording equipment, observation cobble movement feelings can be used
Condition can measure intensity, the Bed Load Movement track of particles collision sound, can also distinguish whether there is pebble bed-load movement, should
Method does not influence bed surface Bed Load Movement when measuring.
To sum up, current bed load sampling technique is sampled in typical section, typical period of time, measures timeliness deficiency,
It can not realize that single-point is measured and recorded for a long time；Measurement space is insufficient, measures and remembers while being not easy to realize multiple spot, multizone
Record；Sampler blocks water more significantly, and situation about putting less than river bed is likely to occur when flow velocity is larger, influences silt discharge and measures essence
Degree.Application No. is 201310508489.9 Chinese patent disclose it is a kind of based on hole survey method basic principle bottom-sitting type it is round-the-clock
Monitoring and measuring method, this method are only applicable to fine sediment river to bed load sediment in real time；Underwater camera observation procedure
It is affected by flow condition, nearly bottom silt content, there is also time and the limitation in space, therefore this method is only applicable to hang
Husky silt content very little, the river water shallow river big compared with clear, sand grain.
