渗井是用以集取河床渗透水和河床潜流水而设置在河床上的大口井。因而在设计中它突破了沿河布置大口井时,井与河流水边线的距离一般不宜小于15～30米的旧框框。渗井取水是利用井内抽水形成的水位降落,造成井水与河水之间的水头差,以引导井周河水向下渗透,通过河床含水层的天然过滤而得到净化后进入井内。实践证明,在中小城镇和工矿企业的给水工程中,利用它从河
Infiltration wells are large wells set up on the river bed to collect permeate water from the river bed and subsurface flow in the river bed. Therefore, in the design, it broke through the layout of large wells along the river, and the distance between the well and the river water line should not be less than 15 to 30 meters. Infiltration well water extraction is the use of the pumping water in the well to form a water level drop, causing a head difference between the well water and the river water, so as to guide the downhole river water to permeate down through the natural filtration of the river bed aquifer and then enter the well. Practice has proved that in the water supply projects of small and medium-sized towns and industrial and mining enterprises, use it from the river
