Coral island underground fresh water reservoir and construction method thereof
The invention discloses a coral island underground fresh water reservoir and a construction method thereof. The coral island underground fresh water reservoir comprises an annular vertical anti-seepage body and an underground storable reservoir basin defined by the annular vertical anti-seepage body, the annular vertical anti-seepage body is an underground cutoff wall or an anti-seepage curtain, is arranged along the outer edge of a coral island reef and is used for changing the seepage boundary of underground water, the purpose of expelling salt water and storing fresh water is achieved, thebasic function of storing the fresh water in the reservoir is achieved, and the underground reservoir basin is an underground loose coral gravel soil body defined by the annular vertical anti-seepagebody. According to the coral island underground fresh water reservoir and the construction method, the occurrence form of the underground fresh water of the coral island reef is changed, so that the small coral island reef which is not easy to form an underground fresh water lens body in a natural state can also form an underground fresh water resource; the underground fresh water is intercepted,the total amount of the underground fresh water resource is increased, the problems that under the natural state, the available fresh water amount of the coral island reef is small, and the fresh water lens body is unstable and fragile are effectively solved, and social and economic benefits are remarkable; and surface vegetation conservation is facilitated, and ecological benefits are remarkable.
本发明公开了一种珊瑚岛地下淡水水库及其构建方法。所述珊瑚岛地下淡水水库包括环状垂直防渗体及其所围成的地下可贮水库盆，所述环状垂直防渗体为地下截水墙或防渗帷幕，沿珊瑚岛礁外缘设置，用于改变地下水的渗流边界，达到驱咸水蓄淡水的目的，实现水库蓄淡水的基本功能，所述地下可贮水库盆为环状垂直防渗体所围的地下松散珊瑚砂砾土体。本发明改变了珊瑚岛礁地下淡水的赋存形态，使天然状态下不易形成地下淡水透镜体的小珊瑚岛礁也可以形成地下淡水资源；截留地下淡水，增加地下淡水水资源总量，有效解决了天然状态下珊瑚岛礁的可利用淡水量小、淡水透镜体不稳定和脆弱的问题，社会和经济效益显著；有利于涵养地表植被，生态效益显著。
