Abstract: This is an advanced reservoir construction method. Its characteristics are to build reservoirs at flattened wide coast intertidal zones or bays near sea gates of rivers, firstly establishing reservoir external embankments at marked scope periphery, presetting a plurality of sea water inlet/outlet gates at proper positions of reservoir external embankments, after completing reservoir external embankments, all gates are closed at the same time when there is no sea water or fewer sea water remains inside reservoir external embankments during the great ebb as low tide, afterward completely sealing the gates with steel concrete; next performing construction work for reservoir internal embankments, after completing reservoir internal embankments, immediately performing digging work of soil/rocks inside reservoirs, stacking dug soil/rocks between reservoir internal embankments and reservoir external embankments to solve the outlet of soil/rocks at the same time while strengthening embankments and creating embankment reclaimed lands. The construction location of reservoirs can also select intertidal zones near bay of sea gate of river. The origin of water source of reservoirs is rainwater collected at large area catchment basin of reservoirs firstly, and clean raw water introduced from nearby rivers secondly, and flood in a large number collected in typhoon season or rainstorm or heavy rainfall thirdly, and takes iceberg dragged from north and south poles as supplemented water sources fourthly. A plurality of blocks should be increased inside reservoirs and respectively taken as a plurality of stilling basins, a plurality of purified water basins, and a plurality of water storage tanks continuously for people's livelihood water, irrigation water and industrial water. Raw water inlets of reservoirs are disposed with water gates. Raw water at different time and different sources is introduced into different stilling basins and different purified water basins, or even different water storage tanks. The way of delivering reservoir water is to dig a faraway water storage tank that is lower than the low limit elevation of efficient water level of reservoir. Water is delivered between faraway water storage tanks by using communicating tube principle, and finally water in the faraway water storage tank is pressurized to pump to user ends everywhere. After constructing external embankment and internal embankment at reservoir, soil/rocks inside reservoir is dug to stack between the reservoir external embankments and the reservoir internal embankments to solidify embankments and create vast embankment reclaimed lands that are taken as transportation roads, park green fields, residential regions and taken as airports, docks or non-toxic disposal soil/rock stowing places and windbreak forests. To reduce evaporation of reservoir and reinforce the utilization of water surface of reservoir, water surface athletic fields or leisure boat dwellers, water malls, water organic farms, etc. are constructed by buoys on water surfaces of reservoirs. To increase the utilization value of reservoirs, it can be divided into people's livelihood water basins, industrial water basins and irrigation water basins, wherein industrial water basins and irrigation water basins can be constructed with swimming pools or waterparks and taken as producers of fish farming or quality agriculture. The people's livelihood water basins can be extended as tap water purification, exposure, and disinfection facilities, directly providing high quality family tap water. Large area solar cell panels or wind power generation facilities can be disposed above reservoirs or embankments to deal with power production or operate seawater desalination or produce excellent diluted water, deep ocean seawater or deal with production of sea salt through generated power. In addition, sea sand rinsing fields can also be constructed on embankment reclaimed lands of reservoirs. During plentiful water source period, sea sand is rinsed by remained pure water so as to deal with side job of gravel supply.
