Description
?
Technical field
The invention belongs to surface deposit acquisition technique field, shallow water territory, particularly relate to a kind of soft cloth back cover formula shallow water territory original state surface deposit sampling thief.
?
Background technology
The surface deposit in shallow water territory takes place to corrode and suspend under hydrodynamic effect repeatedly owing to be subjected to the loose and high influence of water cut of its quality easily.This is not only to the migration of chemical substance between sedimental physical arrangement, water body-sediment with distribute and produce considerable influence, and also can produce to a certain degree influence to the ecologic environment feature of bio-transformation behavior and water body.People adopt field inspection and lab simulation method to study the Changing Pattern of shallow water territory surface deposit usually.Because field inspection hydrodynamic condition uncontrollable, often cause the systematicness of experimental result and repeatable relatively poor, in addition in the experimentation human and material resources expend bigger, so the actual operation of field inspection method is not good.And the lab simulation method is to realize that simulating lab test is the basis, and the original state surface deposit by adopting no sequence disturbance more can guarantee accuracy and the authenticity of simulated experiment as the experimental simulation material.At present, shallow water territory surface deposit sampling thief commonly used has freshwater mussel formula sampling thief and columnar sampler, and they have the following disadvantages: freshwater mussel formula sampling thief can produce destruction to physical arrangement and the sequence structure of surface deposit in sampling process, and it is lower to be sampled into power; Columnar sampler can only be gathered the sediment that area is less, the degree of depth is darker usually, and can produce destruction to physical arrangement and the sequence structure of surface deposit equally when being transferred to the simulation container, the sampling area that can't satisfy the simulating lab test needs is big, sampling depth is shallow, the experimental simulation needs of undisturbed surface deposit.
Chinese patent application 200810153883.4 discloses " a kind of grabbing superficial deposit sampler ", though this sampling thief has out/closes the control function, be conducive to sampling thief and insert sediment smoothly, improve sampling efficiency, but this sampling thief can produce extruding to sediment in closing course, and sedimental physical arrangement and sequence structure are produced disturbance and destruction.And for example Chinese patent application 201210062438.3 discloses " a kind of water body surface deposit does not have the box sampling thief of disturbance ", this sampling thief is to improve on the basis of freshwater mussel formula sampling thief to form, though it is clear that this sampling thief has the surface deposit water and soil interface of collection, the sediment sequence remain intact with sampling process in be not subjected to advantages such as disturbance, but because its closed manners is the extracting formula, uncontrollable sedimental sampling quantity, in sampling process, cause the sampling failure easily, and sediment its physical arrangement and sequence structure when shifting are easy to generate destruction, directly influence authenticity and the accuracy of simulated experiment.
Chinese patent application 200810126080.X discloses " manual rotation type column shaped deposit sampling instrument ", this sampling thief can be under manual rotary manipulation, can gather the column shaped deposit of desired depth easily, and can keep sample not have disturbance and sequence fidelity in the sampling process, but sediment is transferred to the destruction that will inevitably cause physical arrangement and sequence structure to sediment the process of simulated experiment container from the sampling bucket, directly influences the no perturbation of sample.And for example Chinese patent application 201110087077.3 discloses " a kind of river deposit column-shaped sampling apparatus ", though this device is provided with pipe in the separate type sampling, can make sediment keep realizing under the virgin state shifting, but the sampling area of this columnar sampler is little, and sampling depth is dark excessively, can't be applicable to that sediment area in the simulated experiment is big, the needs of depth as shallow.
How to overcome the deficiencies in the prior art and become one of emphasis difficult problem that needs to be resolved hurrily in the surface deposit acquisition technique of current shallow water territory.
