Netherlands breakwater (Scenery) Satellite maps
The world's most spectacular is the largest tide gate built in the Netherlands is not by chance.The Netherlands in Western Europe, the endangered North Sea, the entire state of potential low-lying, river aspect, staggered channels, over the dam, the area of nearly 50,000 square kilometers, of which 1 / 4 at 1 m above sea level below, for a long time, the Netherlands and the sea, the fight against flooding And rely on the construction of dams to protect their survival and development.Without these moisture-proof dam, when the tide comes, "half of the country" will fall into the underwater.Low-lying coastal areas of the Netherlands, the size of raging rivers Zonghengjiaocuo water potential, coupled with this band Chaoci larger and prone to storm surge disaster, the people of the Netherlands to build a large number of protective facilities, the most prominent is the bridges and dams.In the capital city of Amsterdam has more than 1,000 bridges, 1,000 people have averaged a bridge, indeed, "Bridge City."The Netherlands is the world's deteriorating environment to take the most active measures to control one of the countries, far away in the 13th century began with Wai Hoi Zaotian approach to the expansion of land.In Wai Hoi Zaotian, in order to drain farmland in the water, the Dutch have long started to use wind energy, to build a large windmill pumping and thus the various types of everywhere windmills, a number of buildings the city of Amsterdam Also completed a similar windmill-like, Dutch windmills have become a distinctive characteristics, no wonder the Netherlands "Windmill Kingdom," Blair said.Netherlands this century, the most prominent of the sea-there are two.IJsselmeer is a project, from 1932 until 1994 completed before and after experiencing 62, completed a 32 km long promenade on the sea, in nautical miles Wai to a nearly 10,000 square kilometers of IJsselmeer other One is nearing completion of the Delta project, the project is by far the world's largest moisture-proof projects.Construction site southwest of the Netherlands is the new West Sier De Water Crossing, the low-lying here, the river aspect, the upper reaches of abundant water in flood season by storm surges serious disaster.In the early 1980s after proof that the establishment of a switch-mode mobile storm surge protection of the gate is feasible, the relevant government departments to open tender, from six kinds of programmes selected the design, code-named BMK construction programme as a basis.The project includes two huge tide gate door, usually kept the door with moisture-proof gate of the dock, the river channel formation, moving moisture-proof doors and gates of the power supply drainage facilities and computer information management system, and several other parts.Moisture-proof gate door is the key to the project site.The door is divided into two, each fan showed a fan-shaped gate, the gate width of about 300 meters, the use of take-off and landing of the ship-cavity gate, the gate on the hull 22 meters high, 210 meters long, divided into a number of chamber, like the same container One for the installation of electricity and hydraulic devices in electrical room, the other chamber is used to control water entering and leaving through the hull of the PM10, every fan, weighing about 36,000 tons gate.Computer information management system is used to start and stop gates, and to provide timely and dock gate chamber from top to bottom water manipulation of information.Moisture-proof gate operating procedures, generally comes when the storm surges, such as the water level over the Amsterdam annual mean sea level of 3.2 meters, moisture-proof gates will be closed, the process is in moisture-proof gates closed before the first channel of water into dock, Stored in the dock, the tide gate float, and open the dock gate, with moisture-proof gate of the locomotive moving to the central waterway, moisture-proof gates open at this time in the chamber, so that access to water, moisture-proof gates from the river to sink 1 Metres, the use of jet-washed cement sediment on the riverbed, the river bed to be clean, smooth moisture-proof gate landed on the riverbed, two of the gate is 360 meters wide off the river, which completed the closure of moisture-proof gate procedures, to be After the storm surges, moisture-proof gate re-opened, the first moisture-proof gate from the inside of the chamber of water, moisture-proof gate to float, with moisture-proof gate of the locomotive Tuohui dock after dock gate closed, then emptying stagnant water dock, started the end of .Through the forecast, moisture-proof gate closing time is generally not more than 30 hours, during which time will not cause flooding caused by rising river water.If moisture-proof gate inside the river may rise more than moisture-proof gate of the sea water level, floating on a tide gate way to the river discharge into the sea below.The moisture from the engineering design of the Millennium is one in the storm surge to consider, in order to guarantee the normal operation of moisture-proof gate function, a year in the waterway relatively idle, the first exercise.The total project investment of about 900 million U.S. dollars, it's built so that the Fokker angle above the Rotterdam Delta region more than 100 million residents from storm surges disaster in that country.
