在水井建设中,井管设计与施工的优劣,直接影响水井出水量的大小和水井寿命的长短。而滤水管部分(即花管)则是水井的心脏,尤为重要。目前,水井报废率较高,其最主要的原因是滤水井管的设计不合理和施工质量较差。运城市第四纪地层中的水井,井管设计一直沿用包棕或填入不规格的滤料的方法。包棕的方法,是在任何含水层中都包数层棕 In the construction of wells, well pipe design and construction of the merits, a direct impact on the size of the well water and the life of wells. The part of the drain pipe (ie flower pipe) is the heart of the well, which is especially important. At present, the rejection rate of wells is high, the main reason is that the design of filtration wells is unreasonable and the construction quality is poor. Quaternary strata in Yuncheng City, wells, well tube design has been used to pack brown or filled with non-standard filter media. The method of bagging is to pack several layers of brown in any aquifer
