Through the knowledge collation of the architectural knowledge column of this website, Zhong Da Consulting has the following basic information about Haicang Tunnel:
Haicang tunnel is 9.03 kilometers long, of which the tunnel is about 6.4 kilometers long. The tunnel is excavated by drilling and blasting method, and the deepest part of the tunnel is about 72.6 meters above sea level. According to the standard of two-way six-lane urban expressway, the design speed is 80 km/h, and there are three interchanges on the whole line. The planned construction period is 4 years, and it is expected to be officially opened to traffic at the end of 20 19.
Haicang Tunnel Project connects Haicang District and Huli District, starting from Ma Qing Road Interchange in Haicang District and crossing the western waters of Xiamen in the form of a tunnel. The tunnel entrance is located near the intersection of Haicang Avenue and Yongjun Road, enters Xiamen Island near Yu Xiang Wharf, goes along Xinghu Road in Huli District, and finally reaches Torch North Road east of Shigushan Interchange.
Haicang tunnel function:
Haicang Bridge is the only western passage connecting Xiamen Island and Haicang, with an average traffic volume of more than 654.38+10,000 vehicles, far exceeding the design carrying capacity. It is even more congested during peak hours, and Haicang Bridge is already overwhelmed. After the completion and opening of Haicang subsea tunnel, the traffic pressure of Haicang Bridge will be greatly relieved. At the beginning of June this year, according to the traffic statistics report of "four bridges and one tunnel" in Xiamen released by relevant departments, Haicang Bridge, which was originally designed with a daily capacity of 52,000 vehicles, now has an average daily capacity of 12.7 1.78 million vehicles, exceeding the standard 144.57%, which has reached the state of traffic congestion. The completion and opening of Haicang subsea tunnel will play an important role in diverting the traffic of Haicang Bridge.
In addition to relieving traffic pressure, Haicang Cross-Harbour Tunnel will greatly shorten the distance between Maluan Bay and Xinyang Industrial Zone and the northwest of Xiamen Island. According to estimates, it used to take about half an hour to drive from Xinyang Industrial Zone to Xiamen Airport. After the tunnel is completed, the travel time will be shortened by more than half.
The construction of this project has added a lot of color to the construction of Xiamen-Zhangquan three-dimensional transportation network in Haicang. The Haicang subsea tunnel will build a three-dimensional transportation network in the future together with the key land and railway transportation projects under construction or planning, such as Xiamen-Zhangzhou Cross-sea Bridge, Xiamen-Chengdu Expressway, Xiamen-Zhangzhou Tongcheng Avenue and Rail Transit Line 2, which will greatly enhance the radiation capacity of Haicang New City, help to form the effect of radiating Zhangzhou, Longyan and even Guangdong and Jiangxi, and build Haicang into a "Southeast International Shipping Center, Haixi Advanced Manufacturing Base and Xiamen Healthy Ecological New City".
