Luoyang DingDing northeast and zhongzhou road intersection, is home to luoyang public transportation corporation, its basic position in the center of the luoyang city. Today, it is a city sui and tang dynasties of luoyang palace city hall display protection engineering construction site & ndash; & ndash; The tall tower crane, frequent in and out of the vehicle, has been out of the ground of the steel structure framework attracts many people's eyes.
How to protect the important site of sui and tang dynasties of luoyang city? How to do in the construction site without damage? After the completion of the protection of the building what look like? With the readers' questions and concerns, our reporter walked into the hall to show protection engineering site, the excavation protection shows the engineering behind the news.
What is the work of the ancient hall?
It is 294 feet high, three layers, it is cloth of the empress wu zetian decrees, entertain princes, worship hall, is her dominant center
Mencius said: & other; Throughout, hall, the hall also king &; ; In du fu's "shek kwu song said: & other; Open hall ChaoHe, governors throughout his sword grinding & sound phase; ; "Mulan phrase" in such said: & other; Return see right, right to sit hall & throughout; .
Hall is? The ancient ritual of highest specification building, is the place where emperor declared of church and state.
So, wu zetian period's hall in where? This problem, as the cultural relics of luoyang excavation and conservation have the answer.
In 1986, the city of luoyang in northeast DingDing zhongzhou road intersection area planning and construction of building, the bus company construction personnel excavation foundation of a house and found a buried in the soil of ancient brick. Continue to clean up along the ancient brick, a brick wall.
Chinese academy of social sciences, archaeology team staff rushed to sui and tang dynasties city, immediately organized several group after excavation. After a few days and nights of excavation, a construction sites appear in front of the world. Measurement of the size of it, found ten thousand square meters!
Combining the relevant historical materials and sites, archaeological experts concluded that this site is in the history of Chinese literature the first female emperor wu zetian's hall.
Literature on the hall has the following description.
Hall, 294 feet high, north-south, east-west 300 feet each, a total of three layers: the lower sides corresponding to four, that is, spring, summer, autumn and winter; 12 middle method are for dome, Kowloon holding on; On the upper method twenty-four solar terms, also for the dome, ShiTieFeng, higher zhangs, decorated with gold. In the hall with a huge wooden pile, as a bucket Gong beams attached to the trunk, upper and lower penetration, vientiane palace.
Hall, its location has a dry YangDian emperor yangdi. In 621, its flat Wang Shichong mess of the house was burned down. In A.D. 665, tang dynasty the emperor dry yuan temple built on site. In 688 AD, the empress wu zetian ordered the demolition of dry yuan temple, the hall built on the site.
What is the majestic palace? It's wu zetian in luoyang acting palace. But, it is different from general palace: here, in addition to the emperor to promulgate decrees, accept ChaoHe, treats princes and important government activities such as debate lectures, also worship the 2nd face & ndash; & ndash; Hall, the function of shoulder the sacrifice.
Later, the hall was destroyed in the rebellion.
What is the new hall?
It is a 20000 - ton, have protective shelter ancient line of steel structure, covered the hall site, has multiple functions such as protection and display
This morning, the reporter sees in the engineering construction site, the hall octagon steel structure steel beam on the ground has begun to take shape.
& other; Hall show construction is an ancient building line protection of steel protective shelter, is a 20000 - ton monster! Throughout the &; Sui and tang dynasties of luoyang palace city urban engineering headquarters Zhou Haitao introduction, display hall protection buildings are neither restores ancient ways, nor antique buildings. Therefore, the significance of the new hall is completely different from the ancient imperial palace hall, its design concept is totally different from the ancient hall.
Say simply, it is a modern large-scale steel structure protection shed, the bottom from the east, west, south, north three layers stylobate layers of curl upwards, finally form the octagon pavilion slope protective shelter. Figuratively speaking, the new hall, in hall site cover a large shield, the shield in realization of multiple functions such as protection, show and visit.
Why the new hall is a steel structure with ancient line protective shelter? Because, although the new hall is not recover to hall, but fully consider when building the basic shape of the original building: for example, new hall USES the octagon three-tier stylobate, three-layer stylobate is recorded on the historical hall of intentionality.
How big is the size for the protection of the tent? Zhou Haitao said, protective construction total 21 meters high, things, the north and south 105 meters wide, a total construction area of nearly 9880 square meters, the total weight of more than 20000 tons.
The new hall and hall site contact embodied in where?
New tricks so & other; Deductive & throughout; Hall: don't do image restoration or fake, according to hall's historical image display of intentionality, standing on the floor in the new hall can visit hall site
Should not only can protect the important sites, but visit and display function, the new hall in design has its unique feature.
Hall protection shows the building covering the full extent of the site, its appearance not do image restoration or fake, but using the octagonal plane shape, three columns on each side to step stairs three layers of luck receiving gate, luck receiving palace, three on each side to show intentional elements such as history books recorded in historical image's hall.
New hall has two layers: the layer and underground layer.
Layer on the ground floor with three-layer stylobate is high, east, west, south, north three steps, each side has three sets of doors. The rest four multi-function hall, using multimedia show means past dynasties to the tang dynasty in luoyang city appearance, HeLuo people life scenes, miyagi archaeological course content to display.
Site protection hall the underground layer of the excavated area.
Municipal administration of cultural heritage, sui and tang dynasties of luoyang palace city, deputy director of engineering battalion commander Wang Mulin said that for the same show has unearthed hall center column column around the development and application of part of the site, from the floor of the ground floor of a down, height of 13.26 meters.
In particular, the central hall center part of the glass floor laid is 11 meters in diameter, made 11 meters in diameter glass curtain wall glass floor down to the site surface, the height of 13.26 meters.
Glass floor standing in 11 meters in diameter around the banisters look down, can see hall ZhuChuShi and other sites. Railings outside, it is precast floor ground: if due to the need of archaeological excavations, pull down floor can work.
How is the function of the new hall?
illar of independent 194 in fine sand and notoginseng lime soil cushion, let more than 20000 tons of heavy & other protective shelter and sites; No root & throughout; Connection, protection of the site
LiuJian construction group co., LTD., henan hall, head of the technical department JiHaoJie calculated the weight of the steel protective shelter: protect tent to use all kinds of steel 2296 tons, use of floor slab weight more than 6500 tons, together with the other all sorts of structural members, the total weight of more than 20000 tons. The main weight by 194 precast beam composed of independent column is passed on to the ancient rammed earth, it requires that the ancient rammed earth's carrying capacity is 40.5 tons per square metre.
In the history of sui and tang dynasties in luoyang city repeatedly damaged, currently preserved ruins are the soil site. On soil sites protection engineering construction, protection, not destruction is one of the most fundamental principle. So, such a modern behemoth built on the ruins, ruins can withstand?
no problem
It is hard to imagine: based on the site protection, the purpose of school of architecture, tsinghua university doctoral tutor, the famous design expert Guo Dai thus Heng switches to the design of this modern monster unexpectedly & other; No root & throughout; .
JiHaoJie said, through scientific experiments found that ancient rammed earth's carrying capacity is 23 tons per square meter, far can not meet the requirements of 40.5 tons per square meter, how to do? In order to protect the display engineering, on the ancient rammed earth excavation, not driving: construction, the site first rammed earth covered with a 60 cm thick layer of fine sand and fine sand with a 40 cm thick layer of notoginseng lime soil. Don't dismiss the composed of fine sand and notoginseng lime soil 1 m thick cushion: have the cushion, the ancient rammed earth bearing capacity is 40.5 tons per square meter. No excavation and pile driving, 178 pillar of independence & other; Sat & throughout; Notoginseng dust, completely & other; No root & throughout; .
& other; Independent column & throughout; What is the row? & other; Prefabricated built-up beam & throughout; And what's the matter?
JiHaoJie said, & other; Independent column & throughout; Bearing to protect the pillars of the building is: after the completion of steel beam and one integrated mass, independent assembly, during the construction of so called independent column.
Because the position is different, different bearing capacity, the size of the hold up to protect the pillars of the building also each are not identical. Specifically, range 1 m to 10 m tall, horizontal section length of 0.5 m to 0.9 m, width 1 m to 7.5 m range.
Due to the large vibration of mechanical construction will have an impact on the site, all by 194 independent columns & other; Prefabricated built-up beam & throughout; After assembled, all of them in the workshop ready to site and installation.
Among them, one of the biggest pillar of independent of surface area of 75 square meters, made up by more than 40 assembling precast beams, finally by the wire rope wear even after fixed as a whole, its bearing capacity is 1440 tons. It is understood that such a large independent column has eight root.
194 pillar of independent use of precast beam total to 2796.
What is the biggest characteristic of the new hall?
It is real & other; Green building & throughout; Completely reversible, the construction process, but without damage the ruins of all removed, leaving space for later generations of archaeological work
Wang Mulin said hall show building protection was & other Green & throughout; : it has the whole construction program of reversible, renewable and environment protection, etc.
What is & other; Reversible & throughout; ? Wang Mulin said, want to understand the cultural connotation of sui and tang dynasties of luoyang city, may need efforts of several generations. Like Roman Pompeii, archaeological work for over 230 years, is still doing. Luoyang show great site protection engineering is faced with a topic: how to make archaeological leave enough to adjust and improve space? In simple terms, when the master more new materials, new technology of later generations to big sites protection, when the display again, they can remove our construction & other Protective shelter & throughout; ? When excavations are required, can be easily dismantled site above floor slab and the steel structure?
The builders of the new hall are considered.
Hall protection structures are all made of the steel structure and fabrication, steel anchor bolt connection. If need to tear down in the future, after unloaded bolts can be removed and prefabricated components can overall carrying, and can be used in other construction projects.
Moreover, hall protection shows the interior construction USES light guide: light pipe surface is reflective coating rate is 99.7%, natural light can be converted to light source, to reduce the use of artificial light, and eliminates the ruins of the ultraviolet radiation.
Hall, after the completion of the steel structure protection shed all three layers of stylobate and octagonal pavilion slope protective shelter house will plant on artificial turf, the protection will become a huge green buildings.
The emergence of the new hall will appear abrupt?
In fact, the new hall can't hold a candle to Tang Mingtang from scale, built in the spring of next year it will make photograph reflect ancient civilization and modern civilization
Careful readers may find that, in a hall is no tall buildings around the town of sui and tang dynasties of the palace city. This, in fact is the result of decades luoyang cultural relics protection.
So, in a modern city downtown show the protection engineering, will appear abrupt?
Wang Mulin said, sui and tang dynasties, hall and heaven is in luoyang city miyagi's tallest building. The protection engineering about 21 meters high, will not appear abrupt. In fact, it will become a landmark of the region, make the ancient civilization and modern civilization can hand in photograph reflect, become a cultural symbol of imperial city in one thousand.
With hall protection shows the project on schedule and is expected to next peony to the meeting, a collection of cultural relics protection and multimedia display function in a body's new hall will appear in front of the world.
