Description

Double sea dike reservoir and construction method thereof

The invention relates to a reservoir construction method, in particular to a reservoir construction method with innovation and multiple added value.

Among the world's water resources, 94% is seawater, and only 6% of fresh land water, while in land fresh water, 77.2% is distributed in the north and south poles, and 22.4% is in the deep underground, which is difficult to develop, only 0.4%. Fresh water can be used to sustain human life.

According to the World Water Forum, one in three people in the world is currently in a water shortage crisis, mainly in Africa and Asia. No matter whether it is rich or poor, it faces the threat of rapid water reduction. The problem of water shortage has worsened. Social panic and turmoil are frequent, especially among the poorest countries and those who are extremely undernourished, worse than experts have previously predicted.

So far, the world has been unable to do anything about how to increase clean fresh water. In Taiwan, for example, there is a water shortage crisis every year. However, the continued construction of the reservoir is due to the difficulty of location, environmental protection and the increasing cost of land acquisition. Difficulties, as for seawater desalination projects, are too costly to implement. On the other hand, during the flood period, huge amounts of water have flowed into the sea because there is no proper water-bearing place. Therefore, it is imperative to create a huge and appropriate water-reserving space.

In the 1960s, drinking water was scarce in Hong Kong. The Hong Kong government completed the world's first sea-pool reservoir in 1967. The reservoir works to build a dam at the end of a bay in Tolo Harbour, New Territories, and then extract the seawater. Built. Because the reservoir is located at the bay, and the dam is set up on both sides of the bay, and the seawater is drained into a reservoir, because the levee is not wide enough, not only can the seawater not be drained, but even more, the seawater will infiltrate. The water in the reservoir still contains salt, which is a pity for the US.

Looking at the whole world, using the intertidal zone to set up reservoirs and implement double seawalls, deep excavation of reservoirs, increase of ultra-wide seawalls, consolidation of dikes, and the use of reservoir construction methods for clearing seawater during tidal ebb tides, even separating reservoirs into sinking pools and nets. The construction methods for pools, reservoirs and creating multiple added value have never been seen, and the present invention will certainly bring new hope to human water.
