Background technology
Sediment, as the important component part of the aquatic ecosystem such as lake, reservoir, is the main source of aquatic plants growth desired nutritional, is also the important place that community of aquatic organism is perched and multiplied.Water/sediment interface is the ambient boundary of water and sediment two phase composition, sedimentary particle density, particle composition in interface, all there is obvious graded in chemical substance activity, pH, dissolved oxygen DO (DO), oxidation-reduction potential (Eh), biologically active etc., is that aquatic ecosystem is at the most significant ambient boundary of the opposite sex that is wanting in such as physics, chemistry and biological characteristics; The physical and chemical reaction under biology participates in occurred in interface, comprise oxidation and reduction, dissolve and precipitation, sorption and desorption, migration and conversion, spread and bury, bacteria bio reacts and the effect such as bioturbation, being the importance of water environment geochemical cycle and biosystem coupling, is the important channel controlling and regulate substance use and exchange between water and sediment.The surface sediment samples obtaining original position fidelity seems particularly crucial to the behavior of deep announcement water/sediment interface geochemical cycle.
The type of existing sediment sampler has a lot.In order to obtain in-situ deposition thing many samplings columnar sampler, but the sediment sample of the original position obtained by prior art, sample need be transported to laboratory, sedimental layering sample is obtained by freeze drying or top point-score, these class methods still create disturbance to sediment, cause sequence fidelity not strong.
Utility model content
The purpose of this utility model is to provide a kind of for surface deposit original position stratified sampling pipe, and to realize in-situ acquisition and can meticulous layering, the sediment sample gathered with this device can realize original position layering.
For achieving the above object, the utility model is by the following technical solutions:
A kind of for surface deposit original position stratified sampling pipe, comprise intake pipe, get mud pipe, bottom, cutting head and several hierarchy slicings, connect bottom described intake pipe and get mud pipe, get mud pipe to get mud duct member by several and form, the described xsect of mud duct member inwall of getting is for square, the bottom on foursquare wherein three limits is provided with arc groove, 4th limit offers a sealing slotted eye, and described bottom, cutting head can be connected with the base being arranged on the bottom of getting mud pipe is detachable respectively.
Further, be provided with flange bottom described intake pipe, get mud pipe entirety and be fixed on flange by fixed screw and be connected with intake pipe, the end of fixed screw is provided with wing nut.
Further, the bottom of described intake pipe is provided with outlet valve.
Further, described intake pipe is made up of PVC material.
Further, get mud duct member described in be made up of polytetrafluoroethylmaterial material.
Further, described in get mud duct member and comprise two kinds of specifications, its thickness is respectively 1cm and 2cm.
Further, described hierarchy slicing is provided with handle.
Further, described hierarchy slicing is made up of stainless steel.
Further, the thickness of described sealing slotted eye is 1mm.
The beneficial effects of the utility model are:
Adopt the sediment sample of stopple coupon collection of the present utility model can realize original position layering.The utility model structure is simple, and be easy to operation, easy to carry, by directly carrying out layering to sediment, realize the sequence fidelity of sediment sample, sampling efficiency is high, is applicable to field work.It has good practical value and application prospect extensively in ecological environmental protection technical field.Get mud duct member polytetrafluoroethylmaterial material to make, this material be high temperature resistant, corrosion-resistant, intensity is high, and has very strong sealing.
