Besides the majestic Xijin Bridge, what other historical sites are there in Yongkang?

After Xingtai earthquake, Tiananmen Gate Tower was severely damaged and deformed. The Tiananmen Gate Tower, which has a history of more than 550 years, has been in disrepair due to war and fire. The building structure has been seriously damaged and deformed, and the main body has been seriously sunk. After the founding of New China, it was repaired and strengthened many times, but the problem was not completely solved. From 65438 to 0969, a strong earthquake of magnitude 6 to 7.5 occurred in Xingtai, Hebei Province, which further damaged and deformed Tiananmen Gate. At the end of 1969, the State Council decided to completely demolish the Tiananmen Gate and rebuild it at the original site according to the original specifications and architectural forms.

This article is taken from People's Daily Overseas Edition on April 2, 20051. Author: Yu Minyuan Title: Secret Reconstruction of Tiananmen Square 35 years ago

According to historical records, Tiananmen Square was built in the 18th year of Yongle in Ming Dynasty (1420), and it was named Chengtianmen because it completely imitated Chengtianmen in Nanjing. During the Tianshun period of the Ming Dynasty, that is, in July of 1457, Chengtianmen caught fire and the towers were burned. 1465, Ming Xianzong sent the minister of the Ministry of Industry to rebuild the Chengtianmen Gate from Guiyu, and changed it from a memorial archway to a palace style, basically having the scale of Tiananmen Square now. 1644, Chengtianmen was destroyed by fire. In the second year, Chengtianmen was rebuilt again and completed six years later. Since then, it has been officially renamed Tiananmen Square.

After Xingtai earthquake, Tiananmen Gate Tower was severely damaged and deformed. The Tiananmen Gate Tower, which has a history of more than 550 years, has been in disrepair due to war and fire. The building structure has been seriously damaged and deformed, and the main body has been seriously sunk. After the founding of New China, it was repaired and strengthened many times, but the problem was not completely solved. From 65438 to 0969, a strong earthquake of magnitude 6 to 7.5 occurred in Xingtai, Hebei Province, which further damaged and deformed Tiananmen Gate. At the end of 1969, the State Council decided to completely demolish the Tiananmen Gate and rebuild it at the original site according to the original specifications and architectural forms.

According to the establishment of the army, the construction team was formed. Tiananmen Gate has a complicated structure and great technical difficulty. The Central Committee and the State Council established the "Tiananmen Gate Reconstruction Leading Group" with the participation of the General Staff, Beijing Garrison, Beijing Revolutionary Committee and other relevant departments. Beijing Fifth Construction Engineering Company (now Beijing Construction Engineering Group Wu Jian Company) was appointed to undertake this task.

Beijing Fifth Construction Engineering Company has selected a group of elite soldiers with solid foundation, reliable politics and excellent technology, most of whom are party member and League members. They set up five construction teams, namely, woodworking company, bricklayer company, colored oil company, shelf company and mixed company, with Yao Laiquan, then an eight-level carpenter, as the captain of the woodworking company.

In eight days, the Tiananmen Gate Tower, the world's largest building "ceiling", is 66 meters long, 37 meters wide and 32 meters high. It's hard to cover up such a big building. If steel pipes are used as scaffolding, it will take a month. The scaffolder tied them together with Chinese fir and Artemisia, connected them layer by layer, and set up the ceiling with reed mats. Except for the circular path for feeding, the whole tower was wrapped and not exposed at all. It took only eight days to set up the largest "ceiling" in the world, which was unique at that time. They also temporarily built a boiler room in Zhongshan Park, with water supply and drainage pipes leading to the tower, and several layers of heating pipes were laid around the reed mat. Although it is the middle of winter, the shed is still warm as spring.

In order to keep secrets strictly, not only Beijing residents don't know, but even the staff of Zhongshan Park, which is close at hand, don't know what happened in Tiananmen Square surrounded by reed mats. All the people involved in the reconstruction must keep it strictly confidential and are not allowed to tell anyone, even their families. This is a political task.

The treasure chest in the middle of the ridge tile contains gold ingots, rubies, cinnabar and colored particles. The Tiananmen Gate Tower is made of wood structure except that the base is brick-concrete structure. Master Yao and two men climbed the ladder of Artemisia argyi and climbed to the highest roof tile in the square. According to the order, he wants to find a suitable ridge tile. As for what to do, I don't know. He asked two workers to count the chiropractors from the east and west to the middle, and he stood in the middle position. When each of them has 43 yuan, there are 5 yuan left. So he marked the central ridge tile and quickly reported it to the headquarters.

Command leaders, experts, public security and security personnel immediately boarded the roof. The yellow glazed tile in the middle, 60 cm thick and 80 cm wide, can't be lifted by two people. Master Yao smashed the tile with a crowbar, revealing a 30 cm square wooden box with a pair of exquisitely carved dragon play beads on it. The team leader motioned Yao to open it. Master Yao poked it gently with a crowbar, and the wooden box was crisp.

Master Yao stretched out his arm and took out a piece of "copper pimple". Although the luster is not so bright, it is indeed a gold ingot. Then I took out a ruby the size of my thumb. I felt something like the tip of a red pencil again. When I twist my finger, it becomes vermilion powder. That's vermilion. In addition, there are colorful grains: soybeans, sorghum, black beans, millet and corn. Of course, some are indistinguishable.

It is said that everything in Jin Sinan's wooden box was later turned over to the state treasury.

All the pillars of this tower are made of imported wood. Tiananmen Gate has more than 60 columns, the thickest diameter is 1.2m, and the smallest diameter is 0.6m Each column is 12m long and weighs more than 7 tons. At that time, logs with better or even greater quality were found in virgin forests in Hainan Island and Xishuangbanna, but they were imported from Gabon and North Borneo because of transportation problems. This kind of wood is hard and red or yellow in color. It won't catch fire, it will only smoke. Yao Laiquan, a carpenter for many years, said that he had never seen such good wood.

According to the requirement of "all building materials are updated" in the State Council, wood components are processed by Beijing Guanghua Wood Factory. The newly made wooden columns and beams are all made of integral wood, and all the wooden components have been chemically treated with anti-corrosion, insect prevention and fire prevention.

Seven shell casings were taken from the western mountain wall. When the western mountain wall was demolished, a worker took out a complete shell with a diameter of 9.5 cm and a height of about 45 cm. The headquarters immediately instructed the public security department to take all the surrounding soil away for research.

Later, during the demolition, six shells of the same specifications were successively raised, and these seven shells were always a mystery. In view of the political environment of "taking class struggle as the key link" at that time, this news must not be spread. Where these seven shells are now is unknown.

It takes 6 kilograms of gold to paste gold foil. After the carpentry was finished, all the painted dragons and phoenixes went through the strict procedure of 1 hemp 5 ash 13. Diamond lattice fans used to be operated by hand, which was time-consuming and laborious. This time, after repeated research, a diamond lattice fan processing machine was developed, and the working efficiency was improved by 150 times. Finally, stick gold foil. The rebuilt tower used 6 kilograms of gold, all of which were imported. The painter carefully picked them up with bamboo clips, painted them on the wet paint, and then smoothed them out slightly with a fine brush. ...

Based on the political climate at that time, after the completion of the project, the headquarters set up an inspection team composed of 9 people, and used mine detectors to carry out orderly inspection on all drawings. Mine detectors are very sensitive. Once when detecting a bucket arch, the mine detector suddenly sounded, and the drawings showed that there was no record of nailing here. Finally, the bucket arch was demolished-a carpenter's flat shovel was taken out. Is it ulterior motives or negligence? No one present could see it. At that time, it was not clear whether a task force was set up for this purpose and whether the responsible person was found out.

Later, when the mine detector detected the east stairs, it kept screaming. What's wrong with a flat concrete floor? Call now! I didn't find anything. Later, cement slag was tested because this stone has a high iron content.

1 12 After the secret reconstruction was completed, the Tiananmen Gate was rebuilt brilliantly. From19691February 15, the project was officially started and completed on March 7 1970. The whole construction period is 1 12 days. The project produced nearly 100 specifications and 65438+ 10,000 glazed tiles. A layer of brick is embedded in the foundation wall, and the outer wall is coated with 50 cm of cement. The reconstructed Tiananmen Gate Tower is 87 cm higher than the original one. This is because Tiananmen Square has been sinking for many years. According to historical records, it can be said that Tiananmen Square has been restored to its original height. The reconstructed Tiananmen Gate completely retains the original shape, scale and structural layout, and is fortified according to the 9-level seismic capacity. The east-west rolling shed and the city platform were raised, the parapet became thinner, the signboard was replaced, the elevator was installed, and modern facilities such as power supply and lighting, water supply and drainage, thermal heating, telephone, television broadcasting, news photography and so on were added. According to statistics, there are 2 16 departments in the central government, and there are 2 1 provinces and cities in China, and more than 2,700 people are employed during the peak construction period. The speed and quality of the whole site construction are rare in the world.

After that, the colorful portrait of Chairman Mao was hung, and the placards of "Long live the great unity of the people of the world" and "Long live the people of China * * * and the country" on both sides of Tiananmen Base were replaced with FRP materials and wrapped with iron horns. After the "ceiling" was demolished, a magnificent Tiananmen Square appeared in front of the world.
