反滤回灌井的改进技术

Improved technology of recharge well with filter layer

反滤回灌井是我国山东半岛地下水回灌中广泛采用的一种有效的回灌设施,它由回灌井和回灌池组成。文中分析了反滤回灌井的利用现状及存在的主要问题,提出了综合改进措施,研发了土工织物反滤回灌井技术,并导出土工织物反滤回灌井单井回灌量的理论计算公式。

Recharge well with filter layer is an effective water recharge facility widely used for the groundwater recharge in Shan- dong Peninsula, which is consisted of recharge well and recharge pool. The status of the utilization of the well and the main prob- lems therein are analyzed herein, and then comprehensive improvement measures are put forward. Moreover, the technology of the recharge well with geotextile filter layer is developed along with deriving out the theoretical formula for calculation of a single-well recharge volume for the recharge well with geotextile filter layer.
