摘要
随着河北省压采措施的逐步实施,针对河北省平原区浅层咸水含水层低渗透性的特点,研究适用的水平井、轻型井组、竖井、大口井-辐射井的取水方式,加大地表水与咸水的联合利用。选择中东部平原区以粉砂、细砂为主的咸水区,新建15眼竖井咸水井,单井出水量约15 m^(3)/h,利用牛河引黄水,咸淡水混合比例1∶2.14,开展管道混灌示范工程建设,选择在河北省沧州市东部地区,针对传统竖井无法取水的难题,施工4组水平井+轻型井组+竖井的取水井组,单井出水量45~60 m^(3)/h,利用南排河开展抽咸补淡示范工程建设。
Reduction of groundwater mining are implemented in Hebei Province.According to the characteristics of low-permeability in shallow saline aquifer,explore the suitable water intake methods of horizontal well,light well group,vertical well,large-diameter well with radiation well.Increase the combined use of surface water and brackish water.In central and eastern plain area,15 vertical salt water wells were built and the yield of single-well was about 15 m^(3)/h.In order to carry out the demonstration project construction of blending irrigation,divert the water of the Yellow River to the Niu River.The mixing ratio of brackish and fresh water is 1∶2.14.In the eastern area of Cangzhou,Hebei,aiming at the problem that traditional vertical wells cannot draw water,four groups of horizontal wells,light well groups and vertical well intake groups are constructed with single-well output of 45~60 m^(3)/h.The demonstration project of supplement freshwater to suppress saline water was carried out by Nanpai River.
