Underground curtain for preventing seawater invasion and purifying residual saline water and construction method thereof
The invention provides an underground curtain for preventing and controlling seawater invasion and purifying residual salt water and a construction method thereof, and the construction method comprises the following steps: determining seawater invasion, an underground aquifer and other related areas according to hydrogeological conditions of a coastal region; the combined underground curtain comprises two wall bodies which are distributed front and back in the water flow direction of underground water, a top suspension type wall body is located on one side of an inland underground aquifer, and a sunken type wall body is located on one side close to seawater. The sunken wall body is arranged at the bottom of the aquifer, and the lower part is embedded into the impermeable bedrock; the upper opening of the wall body is positioned between the local sea level and the 10% seawater salinity isoline of the salt water wedge; the upper suspension type wall body is arranged on the upper portion of the aquifer and is built from the earth surface, an opening is reserved in the bottom of the aquifer, and the bottom end of the upper suspension type wall body needs to be lower than the top end of the sunken type wall body; the distance between the upper suspension type wall body and the sunken type wall body is 1/5-4/5 of the height of the sunken type wall body; by means of the technical scheme, seawater invasion can be effectively prevented and treated, and residual salt water in the upstream underground water source after the underground curtain is built is removed.
本发明提供了一种防治海水入侵和净化残留咸水的地下帷幕及其施工方法,根据滨海地区的水文地质条件，确定海水入侵和地下含水层等相关区域；组合式地下帷幕包括两个墙体并且沿地下水水流方向前后分布，包括上悬式墙体位于内陆地下含水层一侧，下沉式墙体位于靠近海水一侧；下沉式墙体设置在含水层底部，下部嵌入不透水基岩；墙体上部开口位于当地海平面和咸水楔10%海水盐度等值线之间；上悬式墙体设置在含水层的上部，自地表开始修建，在含水层底部留有开口，上悬式墙体的底端需低于下沉式墙体顶端；上悬式墙体与下沉式墙体之间的距离为下沉式墙体高度的1/5~4/5；通过本发明的技术方案，可以有效地防治海水入侵，去除地下帷幕建立后上游地下水源地的残留咸水。
