Now on the Lingdingyang, Qingzhou channel bridge "Chinese knot" shined, river-sea direct link ship channel bridge "Dolphin" lifelike, Jiuzhou channel bridge of "sailing" sail tower stands. Hong Kong-Zhuhai-Macao Bridge is like a rainbow to lay the wave, water dragon, between sea and sky in the clouds, forming a beautiful landscape.
United Kingdom newspaper the guardian as one of the "seven wonders of the modern world", one of the Hong Kong-Zhuhai-Macao Bridge. It completed will be the world's longest Cross-Sea Bridge.
It is understood that the Hong Kong-Zhuhai-Macao bridge a total length of 55 km, connecting Hong Kong, Zhuhai and Macau's mega-crossing, including bridge and tunnel works, as well as Hong Kong, Zhuhai and Macao port and connector. Among them, the main works by 6.7 km undersea immersed tube tunnel and 22.9 km-long bridge, and has built two artificial islands East and West on both ends of the tunnel.
To overcome the harsh condition off the coast, building a both of the Mainland, Hong Kong and Macau standard system design life of 120 years of large scale sea channel, Hong Kong-Zhuhai-Macao Bridge known as "the seven wonders of the modern world."
Hong Kong-Zhuhai-Macao bridge construction of the project began on December 15, 2009, after 7 years of construction, bridge bridges finally succeeded in closing. Construction grew up companies in Hong Kong-Zhuhai-Macau Bridge project chief engineer Chen Rufa said, in order to catch up before the arrival of the typhoon season closure, engineers have managed to optimize technical solutions, active communication and cooperation with related parties, rational and effective allocation of resources, so as to ensure the safety of bridge construction with Typhoon.
Amount of steel used to build 60 Eiffel
It is reported that the closure of navigable bridge main bridge project including 3 (Jiuzhou channel bridge and river-sea direct link ship channel bridge, Green Island channel bridges) and deep and shallow non-navigable spans of the bridge. Deep non-navigable spans of 110 m span the whole pier of the bridge steel box continuous girder bridges, shallow non-navigable spans of the bridge by 85 meter long-span steel-concrete composite beams.
In order to reduce the water resistance of bridge Foundation to ensure unobstructed Pai Hong Nachao and channel of the Pearl River, the Hong Kong-Zhuhai-Macao Bridge bearing platform of non-navigable spans of the bridge buried, 188 bridges buried as deep as 8-15 meters below the sea bed, a large scale, is the first time in the domestic and worldwide.
According to press reports, the Hong Kong-Zhuhai-Macau Bridge project near 23 kilometers of bridges for the first time in the massive steel bridge upper structure, amounted to more than 400,000 tons of steel, enough to build 60 Eiffel Tower.
Hong Kong-Zhuhai-Macau Bridge project non-navigable spans of the bridge Foundation is made of composite pile with large diameter steel pipe, bridge abutments, beams, steel box girders, steel Tower using prefabricated on land and maritime transport lifting.
Island tunnel engineering completed more than 80%
Hong Kong-Zhuhai-Macao Bridge bridges was honored as "Mount Everest", and the guardian by British media as "the seven wonders of the modern world." According to the new Express Reporter, at present, the parties to allow the construction of bridge engineering, advance engineering.
Hong Kong-Zhuhai-Macao Bridge two artificial islands currently in road and building construction. As the world's longest immersed tube tunnel, cross harbour tunnel Hong Kong-Zhuhai-Macao Bridge 6.7 km long, is composed of 33 immersed stitching, and currently completing 27 sinking, has built tunnels with a total length of 4.7 km, more than the total length of the 80%.
The first half of next year, is expected to complete the main island and cross-harbour tunnel, then tunnel pavement, construction machinery and electronics, at the end of next year the environmental protection, traffic control and other ancillary works and joint commissioning.
