(2) Before the sampler carries out static pressure sampling, all stainless steel ball valve switches 1 are ensured to be in an open state, according to the lowering progress of the soil sampler, a manual power-assisted handle 2 which is easy to operate is held by hand, the sampler is slowly and uniformly carried out static pressure, water remained in the pipe is discharged through a three-way check valve, air remained in the pipe is slowly discharged along an extension rod, a soil sample slowly enters the sampler, and the lowering is stopped when the sampler penetrates into a relatively hard soil layer by 10-20 cm;
(3) And manually closing a stainless steel ball valve switch A1-1 of the sampler which is still exposed out of the water surface to generate vacuum negative pressure in the sampling tube 7. In the process of soil lifting, the stainless steel ball valve switch C1-3, the stainless steel ball valve switch D1-4 and the like are closed in sequence until the stainless steel ball valve switch B1-2, and the extension bar 3 on each stainless steel ball valve switch can be detached after the stainless steel ball valve switch is closed. When necessary, the sampler can be slowly and uniformly lifted upwards by the aid of the traction rope 8;
(4) Checking the soil sample sampling condition through a visual sampling tube, and performing detailed description and preliminary layering, such as a pollution layer, a transition layer, a normal layer and the like;
(5) Horizontally placing the sampler, opening all the stainless steel ball valve switches 1, disassembling the soil lifting and unloading device 9, then slowly unloading the soil sample from the bottom of the sampler to a soil sample box, describing and recording in detail, and sampling to be detected;
(6) And cleaning all parts of the sampler, completing assembly and waiting for carrying out sampling work of the next drilling hole.
To sum up, the utility model provides a be applicable to river, lake, reservoir, pool simple and easy portable, convenient soil lifting, the visual portable sediment sampler of unloading soil.
