Underground water extraction device and extraction method
The invention discloses an underground water extraction device and an extraction method. The underground water extraction device comprises a well casing, a first piston, a water pumping pipe and a pump machine; a water inlet hole is formed in the well casing; the first piston is arranged in the well casing, and the outer wall of the first piston is attached to the inner wall of the well casing; the first piston divides the well casing into a plurality of water pumping layers, and a water pumping pipe is arranged in each water pumping layer; and during working, the first piston is located at a stratum medium layering position. According to the underground water extraction device, underground water of different stratum media is extracted separately, so that the purpose of separately controlling the water extraction amount of the different stratum media is achieved, the underground water in the target stratum media and the depth is extracted more accurately, the underground water extraction device has better adaptability to pollutants with different densities, and the extraction efficiency is higher and the extraction effect is better.
本发明公开了一种地下水抽提装置及抽提方法，所述的抽提装置包括井管、第一活塞、抽水管和泵机；其中，所述的井管上设置进水孔；所述的第一活塞设置于井管内且第一活塞的外壁与井管的内壁相贴合；所述的第一活塞将井管分割成多个抽水层，每个抽水层内均设有抽水管；所述的抽水管与泵机连接；工作时，第一活塞位于地层介质分层处。本发明的地下水抽提装置，对不同地层介质的地下水分开进行抽提，从而达到分开控制不同地层介质抽提水量的目的，更加精确的抽提到目标地层介质与深度中的地下水，并且对不同密度的污染物有更好的适应性，有更高的抽提效率和更好的提取效果。
