Abstract
The utility model relates to a sampling device used for sampling ambient soil, in particular to a nested ring-shaped soil sampler, wherein a sampling sleeve with a disc flange is internally provided with a next sampling sleeve with a disc flange in a movable fitting way step by step, and the external diameter of the disc flange of the next sampling sleeve is in movable fit with the inner wall of the last sampling sleeve. The nested ring-shaped soil sampler can be applicable to the sampling of various soil, can effectively improve the working efficiency, prevent the cross contamination of samples of different layers, and meet the sampling requirement of samples above kilogram degree, and is easy for popularization.
Description
Technical field
The utility model relates to the sampler, particularly nested circular soil sample collector that is used for the ambient soil sampling.
Background technology
Sampling is the prerequisite that the chamber of experimentizing is analyzed.At present, carry out ambient soil when sampling both at home and abroad, often utilize ring sampler, it is pierced soil after, draw out the sample in the sampler, this method is only applicable to the sampling of mellow soil.At the hard soil sample, adopt the soil profile method usually, the dependence instrument is taken a sample on vertical section after digging out soil profile, this method inefficiency, cross pollution easily takes place in the interlayer sample; Commercial needle-like soil sample collector is limited by sample volume, can not satisfy the sampling requirement of the above sample of feather weight, and is not suitable for the sampling that contains more zone of gravel such as basement rock denudation area; Follow the boring earthenware of exploration process not have typicalness.
Summary of the invention
The purpose of this utility model is to provide a kind of nested circular soil sample collector, applicable to the sampling of all kinds of soil, can increase work efficiency effectively, can prevent the cross pollution of interlayer sample, can satisfy the sampling requirement of the above sample of feather weight, be easy to promote.
The purpose of this utility model is achieved in that a kind of nested circular soil sample collector, the drive pipe that next stage has the disk rib is installed in the drive pipe that has the disk rib step by step movingly, and wherein the inwall of the external diameter of next stage drive pipe disk rib and upper level drive pipe movingly.
When adopting the utility model sampling, the mouth of pipe that earlier first order is had the drive pipe of disk rib pastes ground, knocks the disk rib with iron hammer, pounds into the face of land first order drive pipe concordant with the face of land to the disk rib.The sample that utilizes the sampling shovel to scrape to get in the first order drive pipe (if during touch hard object, available drill rod is smash the soil in the loose first order drive pipe, on one side sampling, pound into drive pipe on one side).Be embedded in second level drive pipe at first order drive pipe then, it is concordant with the residual face of land of sampling in the first order drive pipe to the disk rib of second level drive pipe to repeat aforesaid operations, finish the sampling of second layer sample, by that analogy, finish the sampling of each layer sample.
The utility model is applicable to the environmental surveys sampling of soft and hard soil region simultaneously, compares with the soil profile method, and the sampling of use the utility model can reduce the shoveling amount more than 30 times, has improved work efficiency greatly.In upper layer of soil, introduce probe material, in the utility model sampling process, the quality share that the upper strata sample is fallen into lower floor only is 0.015%, single group sampler is reused and is not seen damaged long-pending deformation more than 600 times.Therefore, the utility model can be increased work efficiency effectively applicable to the sampling of all kinds of soil, can prevent the cross pollution of interlayer sample, can satisfy the sampling requirement of the above sample of feather weight, is easy to promote.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing,
Accompanying drawing is a sectional structure synoptic diagram of the present utility model.
Embodiment
A kind of nested circular soil sample collector, as shown in drawings, the drive pipe 2 that next stage has disk rib 1 is installed in the drive pipe 2 that has disk rib 1 step by step movingly, and wherein the inwall of the external diameter of next stage drive pipe disk rib 1 and upper level drive pipe 2 movingly.The progression of drive pipe 2 is the 3-5 level.The length of drive pipe 2,2 its length increase progressively successively from first order drive pipe 2 to the final stage drive pipe.The progression of drive pipe 2 is the 3-5 level.The hem width of disk rib 1 is 3cm.The wall thickness of drive pipe 2 is 2mm.The drive pipe 2 that has disk rib 1 is made of stainless steel.Surface of the present utility model and weld polish smooth.The external diameter of first order drive pipe disk rib 1 is φ 32cm.
