Sault Canal Emergency Swing Dam
The Sault Canal Emergency Swing Dam is an all-metal structure built by the Dominion Bridge Company in 1896. It sits along the Canadian Sault Ste. Marie Canal, to protect against the rush of water that would occur if something ever damaged the Sault locks. It operates by swinging over the canal and dropping wicket gates into the water. The Emergency Dam was put to the ultimate test on June 9, 1909 when the freighter ''Perry G. Walker'' crashed into the upstream lock sending a torrent of water crashing into the downstream lock. The Perry G. Walker and another ship the "Assiniboia" were sent back into the St. Marys River and another ship that was heading upstream out of the locks the "Crescent City" hit the channel wall. The swing dam proved its worth by slowing down the torrent of water. This example of emergency swing bridge is the last of nine ever built. Other examples were previous in Sault Ste. Marie, Michigan, USA and in the Panama Canal The Panama Canal ( es, Canal d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dominion Bridge Company
Dominion Bridge Company Limited was a Canadian steel bridge constructor originally based in Lachine, Quebec. From the core business of steel bridge component fabrication, the company diversified into related areas such as the fabrication of holding tanks for pulp mills and skyscraper framing. Other Canadian plants were located in Amherst, NS, Toronto, ON, Winnipeg, MB, Regina, SK, Saskatoon, SK, Calgary, AB, Edmonton, AB, Richmond, BC and Burnaby, BC. In the 1960s and 1970s, Dominion Bridge expanded internationally and renamed itself AMCA International (AMCA name effective June 1, 1981). This name was later changed to United Dominion Industries. To keep name recognition alive, the company continued to call its Canadian division 'Dominion Bridge'. Between 1979-1988, the company's Lachine plant operated under the auspices of a subsidiary called Dominion Bridge-Sulzer Inc., which was co-owned by AMCA International and Sulzer Inc. The Dominion Bridge facility in Burnaby, BC operated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wicket Gate
A wicket gate, or simply a wicket, is a pedestrian door or gate, particularly one built into a larger door or into a wall or fence. Use in fortifications Wickets are typically small, narrow doors either alongside or within a larger castle or city gate. The latter were often double gates, large and heavy, designed to allow the passage of wagons, coaches and horsemen. The purpose of wickets was to avoid the risk of having to open the main gates to the castle or city for just one or two individuals on foot. Because the wicket was only one person wide, it only allowed entry one at a time and enabled the guards to better control access. In the Middle Ages the narrow doors in the city walls also enabled late arrivals to gain entry after the main gates had been closed. If the small entrance in the door of a large gate has a high threshold, it may be called a manway. If it is a separate, narrow entrance next to the main gate, it may be called a pedestrian entrance. This type of doub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panama Canal
The Panama Canal ( es, Canal de Panamá, link=no) is an artificial waterway in Panama that connects the Atlantic Ocean with the Pacific Ocean and divides North and South America. The canal cuts across the Isthmus of Panama and is a conduit for maritime trade. One of the largest and most difficult engineering projects ever undertaken, the Panama Canal shortcut greatly reduces the time for ships to travel between the Atlantic and Pacific oceans, enabling them to avoid the lengthy, hazardous Cape Horn route around the southernmost tip of South America via the Drake Passage or Strait of Magellan and the even less popular route through the Arctic Archipelago and the Bering Strait. Colombia, France, and later the United States controlled the territory surrounding the canal during construction. France began work on the canal in 1881, but stopped because of lack of investors' confidence due to engineering problems and a high worker mortality rate. The United States took over the ...

Dams In Ontario
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Buildings And Structures In Sault Ste
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
