Device.
Background technique
Clay, silt, organic matter and other various mineral objects in river,lake and reservior water body, by long-time physics, change
The effects of learning and is biological and water body transmit and are deposited on water bottom, form deposit.One as water body of these deposits
Divide and influence each other with water, while also can reflect water body migration, conversion etc..Therefore, either the historical upheaval of water body is studied also
It is to assess its status, granularity, layer structure and the chemical component of water body deposit are all important index.
Common sampler of aquatic sediments is generally divided into grab type and pillar two major classes.Wherein, grab type sampler is logical
The mode for crossing crawl acquires deposit, and structure is simple, but larger to the disturbance of deposit, is easily destroyed the script of deposit
Structure leads to not that complete section is presented, is also unfavorable for the chemical component of each layer of chromatographic analysis, therefore is only applicable to deposit
The comprehensively sampling of sample is studied.Pillar sampler generally by the way that sampling pipe to be inserted into deposit, then lifts sampling pipe, passes through
Deposit in pipe is taken away water body by hydrostatic pressure together, is then extruded deposit by piston.Pillar sampler is to deposition
The disturbance of object is small, carries out layering research convenient for research deposit.Therefore, either Study of Water Environment or hydrologic research is to water body
When deposit is sampled, it is often used pillar sampler.
However, existing pillar sampler generally releases sediment sample by piston after sampling from sampling pipe.It should
Process one is laborious, and two have disturbance to the cross-section structure of sample.Therefore, it is necessary to a kind of new sediment samplers.
