s1, preparation operation: an operator carries the air guide seat (201) by hand, simultaneously aligns the bottom end of the outer pipe (101) to a specified survey shallow soil position, presses down the air guide seat (201), so that the air guide seat (201) drives the bottom frame (401) to move downwards, in the process of pressing down the outer pipe (101), the gasket (404) is firstly contacted with the ground, when the bottom end of the outer pipe (101) is completely submerged into shallow soil, the ejector rod (405) can push the plugging rod (103) into the outer pipe (101) under the support of the gasket (404), so that the interior of the outer pipe (101) is communicated with the outside through the air holes, and simultaneously sprays harmful gas detection reagents to the top of the air test plate (309) through the atomizing nozzle (308), and then starts the micro gas booster pump (302), so that the micro gas booster pump (302) generates high-speed flowing air flow at the communication position of the air guide seat (201) and the outer pipe (101) through the connecting pipe (303) and the air guide pipe (202), then, gas in shallow soil is sucked into the outer pipe (101), the gas is discharged into the bottom frame (401) through the T-shaped groove and the gas pipe (203) under the driving of high-degree flowing gas flow, the flowing gas flow accelerates the gas in the shallow soil to flow to the gas holes, the concentration of the gas collected in the outer pipe (101) is rapidly increased, and then the micro exhaust fan (310) is started, so that the micro exhaust fan (310) firstly pumps the gas into the gas guide frame (304) through the gas checking pipe (305);

s2, gas safety warning: when gas in the gas guide frame (304) enters the transparent gas testing frame (306), the gas is contacted with the atomized harmful substance detection reagent attached to the surface of the gas testing plate (309), so that the harmful substance detection reagent and the harmful substance in the gas can rapidly generate a color development reaction, whether the harmful substance exists in the gas or not is visually observed through the transparent gas testing frame (306), and meanwhile, the harm of the gas to a human body is judged according to the actual color depth;

s3, gas detection: in the process that shallow soil was inserted in outer tube (101), make top ring (104) support shutoff pole (103) shutoff bleeder vent under the support of spacing spring (105), make outer tube (101) push down in-process earth can not block the bleeder vent, after the operator judges gaseous harm according to harmful gas detect reagent, carry out appropriate safety protection operation, open control valve (205), make the operator effectively gather the gas that flows through control valve (205) through gas detector.
