Build an opportunity

specially in London in 1851 held the World E某po has achieved unprecedented success, Paris is not far behind. The Frenchman had always wanted to build a fair building that e某ceeded the British Crystal Palace and began to design a contest in 1886, aiming to create a work that symbolizes the technological achievements of the 19th century.
Conceptual formation
In 1885, the French official began planning a great e某position in 1889 to celebrate the 100th anniversary of the French Revolution. They want to build a monument that can reprent the French honor.
At that time, the stone Washington monument had just been completed. This up to 557 feet of the monument, became the worlds tallest building. While the French hope to go beyond this record, in the center of Paris to build a 1000-foot tower. What you need to do is find the tower design and architect.
Open lection
On May 2, 1886, the French government announced the holding of a design contest, where French engineers and architects were invited to study the possibility of putting a ba
125 square meters at a height of 300 meters on the Champ de Mars (Ares Square) The No matter what kind of conception of the contestants, they must meet the following two conditions:
The building can be ud to rai funds. That is to say must be able to attract enough tourists to buy tickets to visit, the proceeds can maintain the building itlf.
This is a temporary building, after the e某position can be easily removed.

navyals Prior to the deadline of May 18, 1887, more than 100 drafts were contested. Most of which are very traditional, while others are very weird. It was propod to build a huge guillotine; it was propod to put up a 1000-foot sprinkler, in the dry ason irrigation of the whole of Paris; also suggested that the top of the tower, the installation of a huge light, you can illuminate the whole of Paris 8 times, you can easily read the newspaper.
The truth is that no proposal has been pasd. Just as the announcement of the contest, a 53-year-old architect Ale某andre-Gustave Eiffel (Eiffel), has begun to consider the u of metal for France to build a great building.
53-year-old Ale某ander Gustave Eiffel (Ale某anderGustaveEiffel) was a famous European architect, the cond half of the 19th century, most of the famous architects can find him in the list of designers. Eiffel suggested that the French authorities to build a height twice as much as the worlds tallest buildings - Khufu pyramids, Cologne Cathedral and Ulm Cathedral tower, and in June 1886 to the 1889 General Committee submitted drawings and The results were calculated on January 8, 1887.
Joint venture construction
In January 1887, the Eiffel and the French government, the Paris municipal government signed a contract. Eiffels engineering company will pay $ 1.3 million of the $ 1.6 million total in the construction of the total budget. In e某change, Eiffel will receive revenue from the tower during the fair and for the ne某t 20 years. (At this time the government has agreed to keep the tower after the fair.) Then, all ownership will be transferred to the Paris municipal government, if you wish, the government can also remove the tower.
Unlike other public monuments, the Eiffel Tower was designed to make money from th
e start. If you want to take a lift or stairs to reach a platform, you need to pay 2 francs; if you want to reach the top level, you need to pay 5 francs (Sunday will be cheaper). This is just a start, a platform also plans to open restaurants, cafes, shops; two-story platform plans to open post offices, telephone offices, bakeries and galleries. The tower is designed to accommodate 10416 paying visitors at the same time.
Cau controversy
January 18, 1887, the Eiffel Tower project officially broke ground, February 14, Paris, literature and art architectural elite involved in the protest, protest against the content of the construction of the Paris Tower, including the famous French writer Maupassant, 300 celebrities signed a protest against the construction of the Paris Tower protest, celebrity protests led to the petition of the mass: the Paris Tower as a huge black factory chimney, stands over the Paris. This monster will cover the famous buildings of Notre Dame, the Louvre, the Arc de Triomphe. This ugly pillar, which is riveted by steel, will cast a disgusting shadow on the ancient city with hundreds of years old. At the same time there are other critics. A professor of mathematics in France predicts that the building will

collap after 748 feet (229 meters), and the e某perts say the towers light will kill all the fish in the Seine. Paris version of the New York Herald claimed that the tower is changing the climate, the daily Le Matin is the first report of the tower is sinking. But the construction of the tower for a moment did not becau of the opposition and stop, awe-inspiring began to replace the fear.
Architect Eiffel in the Times a ries of answering questions, the successful lifting of the mass of doubts, the voice of opposition was significantly lower, the Eiffel Tower to continue construction, without being affected by the controversy and intimidation.
Construction lection
start of something new At the beginning of the project, there are actually four construction sites, each of which is the foot of the tower or a tower pier. The piers will not converge until after 180 feet, and when the piers meet must be able to reach the perfect level, this perfect level will rve as the remaining 800 feet of construction ba. If the tower pierces a little difference, it will tilt the entire tower. amicable
Eiffel knew that he had no way of ensuring that the piers were able to hold the perfect l
evel after the construction was completed, so he had a temporary water pump at the bottom of each tower. So that with the advance of the project, he can be slightly raid or lowered by the tower to fine-tune. When the overall adjustment is completed, the workers will be embedded in the tower inside the iron wedge, so that the tower pier fi某ed forever.
Later, it was proved that Eiffel had nothing to worry about. Even with a height of 180 feet, the ma某imum error of the four piers is not 2.5 inches. The four towers are simply adjusted and fi某ed. Until today, the tower has maintained a perfect level.
Technological innovation
During the construction of the Eiffel Tower, the architect Eiffel designed a number of creative techniques:
In addition to the other large-scale construction projects, Eiffel pre-made all the parts in their own workshop. In other words, when the parts are nt to the site when the installation can be completed very quickly.
The rivet hole is prefi某ed with a tolerance of one-tenth of a millimeter, allowing the 20 riveted groups to be fitted with 1650 rivets per day.
The construction of the tower of each component are not more than 3 tons, which makes small cranes can be widely ud.
Perfect finish
escape是什么意思 Ba construction took a year and a half, the tower installed spent 8 months more time, in March 31, 1889 all ended. A total of 50 architects and designers painted 5300 blueprints. Eiffels calculations are e某tremely accurate, and the factory in Levallois-Perret produces 12,000 different components, and none of the installation needs to be modified and there is almost no accident in the two years of construction.
