Engineering characteristics
The expansion of Xia Quan expressway is the first milestone in the history of Fujian expressway. About 80% of the expansion projects are widened at both sides. Generally speaking, it is to draw two lanes with a width of 8 meters on the edge of the original four lanes, thus forming an eight-lane subgrade.
Drawing lessons from the experience of domestic high-speed capacity expansion, the direct widening method is safer, and the direct widening method is like "shoulder to shoulder", which saves land and cost. However, due to the influence of topography, some sections should be widened separately, that is, new roads or new bridges should be built at a certain distance instead of "shoulder to shoulder".
trait
The completion of Quanxia expressway is not only the first expressway in Quanzhou, but also a milestone in the development history of Fujian highway traffic. It has achieved the breakthrough of "zero" in expressway, Fujian, and fulfilled the "high-speed" dream of Fujian people. After the opening of expressway, not only people and logistics, but also business, finance, information and culture flows through it. A person in charge of the project headquarters once calculated an account: Xia Quan expressway, with a total investment of 2.78 billion yuan, earned an average daily income of 470,000 yuan199, saving 5.72 million liters of gasoline, saving more than 40,000 hours of driving time 1028 million times of vehicle trips1028 million times ... These figures are soaring every year, giving people surprises every year. More importantly, this road has accelerated the rise of the economic belt along the route, and every export has become a hot spot for foreign investment.
In order to meet the needs of economic development, Quanxia Expressway, which has been in operation for ten years, entered the widening stage last year, and it is planned to expand in two directions and eight lanes. The Quanzhou-Yongchun section of Quansan Expressway will also be opened to traffic this year. In addition, four new expressway projects have been started in Quanzhou this year, and eight more expressway projects will be built in Quanzhou in the next decade, and the dream of connecting counties in Quanzhou with expressway will be gradually realized. In addition, expressway, such as Xiazhang, Fuquan, Luoning, Luo Chang, Funing, Zhangzhao, Zhang Long and Jingfu, have been built one after another. It is not difficult to predict that Fujian will form a modern expressway network, which will create favorable conditions for Fujian's further economic development.
