河床辐射井系指集水井位于岸边或河床上,而辐射管伸入河流水体底部含水层中。它主要集取河床渗透水,具有出水量大的优点。因此,河床辐射井在国内外给水工程中得到了越来越广泛的应用。然而,从运行经验看,这种型式的辐射井经长时间运行后出水量有减少的趋势(即出水量不变,而水位降深增大)。例如在湖北安陆某厂和某公司 The bed radiation well means that the collecting well is located on the bank or riverbed, and the radiant tube extends into the bottom aquifer of the river body. It mainly collects permeate water from the river bed, which has the advantage of large water output. Therefore, river bed radiation wells have been used more and more widely in domestic and foreign water supply projects. However, from the operating experience point of view, this type of radiation wells after a long period of operation after the water has a tendency to decrease (ie, the amount of water does not change, while the water level decreases deeper). For example, in a plant and a company in Anlu, Hubei Province
