| 摘 要： | 针对临河粉细砂地区水文地质实际,通过室内渗流试验及渗透试验,确定了供水管井所采用的贴砾管的最佳厚度和对应的填砾粒径,证明了贴砾管加装填砾后,出水效果(以出水量、渗透系数、出水含砂量为评价指标)均优于贴砾管,消除了设计中认为贴砾管出水效果与加装填砾无关的误解。并在几年实际应用中得到了证明。

| Abstract: | Based on the data of laboratory experiment,the conclusion about the filter performance of the grail stickled by organic matter can become better when it wrapped up by grails are presented,and the suitable thickness and corresponding grain diameter of grail stickled by organic matter are made certain.The rationality of the conclusion have been proved by several years practices in well structure in Linhe area of Neimen municipality. |
