Yingke Bridge and its connecting line project is an important "one horizontal" in the main framework of Heyuan urban road network and an important east-west main road in the future urban development. After the Yingke Bridge is completed and opened to traffic, it can not only improve the traffic environment on the east and west sides of Heyuan City, but also promote the development of the east of Heyuan City and accelerate the development of the west of Zijin County, which is of great significance to further expand the urban space of Heyuan, facilitate people's travel and enhance the image of Heyuan.
Guangzhou Branch of China Railway No.1 Bureau, the construction unit, has started construction.
On the eve of National Day, the 844-meter Heyuan Yingke Bridge was officially opened to traffic.
It is reported that the Yingke Bridge in Heyuan City has created a number of firsts: the first cable-stayed landscape bridge in Heyuan City and the only cable-stayed bridge with double rhombic single tower and four cable planes in our province; It is the first major infrastructure project to expand and upgrade the central city of Heyuan, the first municipal project to be financed by BT mode in Heyuan, and the first municipal project introduced by Heyuan and undertaken by China Railway No.1 Bureau, a central enterprise.
China pays attention to the stability of the chassis in kung fu, and "practice your legs before practicing boxing". The main tower of Heyuan Yingke Bridge also has two legs: one is a pile foundation, and all the forces of the whole main bridge are supported by 24 pile foundations. Each pile foundation has a diameter of 2.5 meters and a height of 33-46 meters. There are 24 piles in three rows, and 4,800 cubic meters of concrete is poured into the riverbed for more than 30 meters, which is firmly embedded in the rock stratum. The other "leg" is the pile cap, which is 46.35m long, 4.5m high and15m wide. It is made of 3 100 cubic meter concrete, and it is also the largest deep-water mass concrete cap in Heyuan. Concrete pile caps and 24 pile foundations are integrated, and two "legs" support the whole main bridge.
Peng Zezhou, director of Yingkeqiao Engineering Department of Heyuan City, introduced that after the completion of the "chassis", two main towers with double diamond-shaped composite structures will be built, each of which is 95.8 meters high, equivalent to 33 stories high. The main bridge is a cable-stayed bridge with single tower and four cable planes, with a length of 262 meters. It is connected with the main tower from the east and west ends, and connected into a whole by beams at the main tower. The bearing capacity of the whole bridge body is uniformly pulled on the main tower by 136 high-strength galvanized thin steel wire stay cables.
It is understood that from the start of construction to the opening of Heyuan Yingke Bridge, there were more than 30 engineering teams with nearly 2,000 person-times, which lasted 3 1 month. Finally, the main project construction of Yingke Bridge was completed. Only Yingke Bridge used 68,000 cubic meters of concrete and10.2 million tons of steel bars.
The engineering team that painted many large landmark buildings such as Guang Zhouta and Humen Bridge in Dongguan specially painted the Heyuan Yingke Bridge. The 150 floodlight, 1666 contour light and more than *** 1800 searchlights at the top of the bridge tower add luster to the bridge. As night falls, the bridge crosses Dongjiang like a ribbon. From the front, the two main towers form a big letter "M", which is not only the first letter of Mother in English, but also the first letter of Magic, showing the magical beauty of the bridge, implying that Dongjiang water, the water source of Heyuan people, is the mother river that nourishes Hakka people.
