Construction method for recharging fresh water in river into underground reservoir
The invention discloses a construction method for recharging fresh water in a river into an underground reservoir. The construction method comprises the following steps of: taking a stratum funnel area with the low underground water level or exhausted underground water as the underground reservoir, selecting a nearest fresh water river with the high terrain near the underground reservoir as a water taking point, and selecting a stratum with better water permeability in a stratum between the water taking point and the underground reservoir as an underground water channel or an underground river; building a dam at the water taking point, building a reservoir near the bank of the dam, and introducing upstream river water of the river into the reservoir to meet the water recharging standard; and drilling a plurality of recharging wells on the underground water channel or the underground river near the reservoir, building two rows of water blocking walls on the underground water channel orthe underground river between the reservoir and the underground reservoir through connected water blocking piles, introducing the river water in the reservoir into the recharging wells, and rechargingthe river water into the underground reservoir through the underground water channel or the underground river formed by the stratum with better water permeability by means of the ground potential difference between the recharging wells and the underground reservoir and the water head difference in the recharging wells.
本发明将江河中淡水回灌到地下水库施工方法包括：以地下水位低或地下水枯竭的地层漏斗区作为地下水库，在地下水库附近选择地势高的最近淡水河流作为取水点，选择取水点与地下水库之间地层内具有较好透水性地层作为地下水通道或地下河；在取水点处筑建大坝，在靠近大坝岸边筑建一个蓄水池，将河流上游河水引入蓄水池内，使之满足回灌水标准；在靠近蓄水池的地下水通道或地下河上钻有若干个回灌井，在蓄水池与地下水库之间的地下水通道或地下河上，通过相连的堵水桩筑建两排堵水墙，将蓄水池内河水引入回灌井内，依靠回灌井和地下水库之间的地势差和回灌井中水头差的作用，河水通过具有较好透水性地层所形成的地下水通道或地下河回灌到地下水库中。
