Combination type sampler for solutions of soil at different depths

Abstract

The invention relates to a combination type sampler for solutions of soil at different depths. The sampler comprises a handle, a main pipe and an aspirator; the main pipe consists of an adapting pipe,a sampling pipe, an extension pipe and a conical pointed drill bit; the handle is fixed on the adapting pipe, the adapting pipe is arranged at the upmost end of the sampler, the conical pointed drillbit is arranged at the lowest end of the sampler, and the sampling pipe and the extension pipe are mutually combined and connected between the adapting pipe and the conical pointed drill bit. The combination type sampler is convenient to disassemble and assemble, can be used for achieving the purpose of collecting the solutions of soil at different depths through mutual combination of various components when being convenient to carry simultaneously, and can further be used for avoiding causing damage to a soil structure to pollute samples when the sampler is inserted; in the soil solutions collected in a sampling pipe, the suspended matter impurities are removed, and the samples are convenient to treat and analyze further in a laboratory; the device is not only suitable for sampling in anarea in which the soil water content is high, but also particularly suitable for collection of the solutions of soil in some areas, in which soil overlying water exists, and in marsh areas at the same time.

Description

technical field [0001] The invention relates to a soil solution collection device for soil environment detection in environmental engineering, in particular to a soil solution combination sampler with different depths. Background technique [0002] Soil solution refers to soil interstitial water, which is not only the place where soil chemical reactions occur, but also the way for plant roots to obtain nutrients in the soil. Soil solution plays an important role in the study of chemical reactions in soil, the interaction of solid and liquid in soil, the change of nutrients in soil, and the migration and transformation of pollutants in soil. The current soil solution collection devices generally have problems such as sampling will destroy the distribution of soil solution, layered sampling of soil solutions at different depths is difficult, the collection process is easy to pollute the soil solution, and the soil solution collection process is troublesome, especially for diff...

Problems solved by technology

The current soil solution collection devices generally have problems such as sampling will destroy the distribution of soil solution, layered sampling of soil solutions at different depths is difficult, the collection process is easy to pollute the soil solution, and the soil solution collection process is troublesome, especially for different depths. The concentration change of soil solution substances has great scientific research significance, so it is necessary to design a collector that can collect soil solutions at different depths
