Anti-salty method suitable for low-salinity saline water environment and salty water collecting pit structure
The invention discloses an anti-salty method and a salty water collecting pit structure suitable for a low-salinity salty water environment, and the anti-salty method adopts a mode of locally deepening a salty water collecting pit at multiple positions to form a sectional salty water collecting pit structure so as to increase the head loss of salty water upstream. And the pressure energy of the interface of the salt water and the fresh water is continuously changed by repeatedly increasing and reducing the water depth of the sectional salt water collecting pit structure, the kinetic energy of the salt water is dissipated, and the upstream speed of the salt water is slowed down. According to the method, the speed and the salt content of intrusion of salt water to the upstream can be reduced, the engineering cost is saved, and adverse effects on navigation safety of ships caused by poor water flow are avoided.
本发明公开了一种适用于低盐度咸水环境的防咸方法及集咸坑结构，该防咸方法采用多处局部加深集咸坑的方式形成分段式集咸坑结构，以增大咸水上溯的水头损失，并利用分段式集咸坑结构反复增大和减小水深的方式不断改变咸水和淡水交界面的压能，耗散咸水的动能，减缓咸水上溯的速度。本发明能够减缓咸水向上游入侵的速度和含盐量，节省工程成本，并避免形成不良水流对船舶的通航安全造成不利的影响。
