Embodiment 1

[0040]A multilayer soil gas sampler, which comprises: PTFE waterproof breathable hose 1, three-layer plastic protective shell 2, airtight polyurethane pipe 3 and cylindrical plastic pipe 4. Wherein, each layer of plastic protective shell 2 has a cavity, and a number of small holes are provided on its side wall. Two adjacent layers of plastic protective shells 2 are connected by threads, and the ends of the plastic protective shells 2 at the top and bottom are all fixed (can be fixed by threaded connections). There are: protective end caps to protect the inner soft The role of the tube. The cylindrical plastic pipe 4 has a cavity, which passes through the cavity of each layer of plastic protective shell 2 and extends to the protective end cap of the bottom plastic protective shell 2 and is fixed, and the plastic protective shell on the top layer The protective end cap of 2 is provided with a perforation through which a cylindrical plastic pipe 4 passes. The PTFE waterproof an...

Abstract

The invention discloses a multilayer soil gas sampler and a sampling method. The sampler comprises a plurality of layers of plastic protective shells, a cylindrical plastic pipeline, a plurality of waterproof breathable hoses and a plurality of airtight polyurethane pipes, wherein two adjacent layers of the plastic protective shells are in threaded connection, each plastic protective shell is provided with a cavity, the side wall of each plastic protective shell is provided with a plurality of small holes, and a partition plate is arranged between two adjacent layers; the cylindrical plastic pipeline is provided with a cavity, penetrates through the cavity of each layer of plastic protective shell, extends to the protective end cover of the plastic protective shell at the bottommost layerand is fixed; the plurality of waterproof breathable hoses are arranged in each layer of plastic protective shell and are wound on the outer side wall of the cylindrical plastic pipeline; the airtightpolyurethane pipes are arranged in the cavity of the cylindrical plastic pipeline in a penetrating mode, the bottom end of the airtight polyurethane pipe is communicated with one end of the waterproof breathable hose, and the top end of the airtight polyurethane pipe extends out of the top end of the cylindrical plastic pipeline and is provided with two-way valve. The sampler disclosed by the invention can be used for simultaneously collecting gas of multiple layers of soil and is convenient to use.

Description

technical field [0001] The invention relates to a soil gas sampler, in particular to a multilayer soil gas sampler and a sampling method. Background technique [0002] Soil microorganisms decompose soil organic matter and organic nitrogen through mineralization to produce CO 2 、CH 4 and N 2 O and other greenhouse gases, these greenhouse gases are either released into the atmosphere through diffusion, or dissolved in the soil solution, or remain in the soil pores, or are further decomposed and reduced by microorganisms. [0003] The chamber sampler (Chamber) has been widely used by researchers at home and abroad to monitor the flux of soil greenhouse gas emissions. To find out the turnover of gas in the soil, therefore, various soil gas samplers have been developed. For example, Chinese patent CN201710127750.9 discloses a simple deep soil gas sampler and its sampling method. The device buries a waterproof and breathable membrane in the soil according to the required depth...
