Contaminated soil static sounding sampler and sampling method

The invention provides a contaminated soil static sounding sampler and a sampling method, the contaminated soil static sounding sampler is used for being installed at the lower end of a probe rod of static sounding equipment for use, and the contaminated soil static sounding sampler comprises an exhaust waste soil pipe, a soil sample pipe, a reducer union, a screw cover and a pipe shoe; a plurality of exhaust holes are formed in the pipe wall, close to the upper end, of the exhaust waste soil pipe. During sampling, the exhaust waste soil pipe is detachably connected to the lower end of a probe rod of static sounding equipment through the reducer union, the lower side of the exhaust waste soil pipe is detachably connected with the soil sample pipe and the pipe shoe in sequence, the inner diameters of the exhaust waste soil pipe, the soil sample pipe and the pipe shoe are the same, and the outer diameters of the exhaust waste soil pipe, the soil sample pipe, the spiral cover and the pipe shoe are the same.
