Abstract

The invention discloses a groundwater depth-fixed sampling probe, a sampling system and a sampling method using the probe. The groundwater depth-fixed sampling probe comprises: a quick-connect joint; The joint is arranged at the opening; the bottom threaded cap; the inner liner, the inner liner is arranged between the top threaded cap and the bottom threaded cap, and the inner liner is provided with a plurality of holes; and the outer sleeve, The outer casing is set between the top threaded cap and the bottom threaded cap, the outer casing is set outside the inner liner, and a plurality of holes are arranged on the outer casing; wherein, the top threaded cap and the bottom threaded cap It is connected with the outer sleeve through the inner liner, and the diameter of the multiple holes on the outer sleeve is smaller than the diameter of the multiple holes on the inner liner; among them, the quick-connect joint, the top threaded cap, the bottom thread The plug cap, inner liner, and outer sleeve are made of stainless steel.

Description

Technical field [0001] The present invention relates to the field of pollution site investigation and health risk assessment technology, in particular about a groundwater deposition probe, a sampling system and a sampling method of the probe. Background technique [0002] With my country's "refunded two into three", "retreat into the park", "industrial structure adjustment and upgrade" and accelerating urbanization, etc., the production enterprises located in the city, gradually shut down, for urban construction Teng land. However, due to the weak environmental awareness, some companies have caused some degree of pollution to the internal soil and groundwater in the enterprise during the production period. In order to ensure the health and ecological environment safety during this type of site re-development, the Ecological Environment Department clearly requires the need to carry out soil and groundwater pollution surveys on suspected pollution plots. For the confirmation of the...
