Qilu Network Lightning News, October 30 (Shandong Tv Comprehensive Broadcasting Cui Lixia) Following the Shandong High-speed Project Interview Group, the reporter arrived at the construction site of the Jinan-Gaoqing High-speed Project.
At the construction site of Xiaoqinghe Special Bridge, Li Zhenzheng, the person in charge of the site of The Xiaoqinghe Special Bridge, led the team to carry out sprint construction, and he told reporters that the Xiaoqinghe Special Bridge is about to enter the key node of the middle span of Helong, which means that the Xiaoqinghe Special Bridge is about to enter the final stage of construction, followed by the pavement of the bridge deck and the asphalt construction of the road surface.
The total length of the Jigao Expressway project is 93.3 kilometers, and the approved estimated budget is 13.80 billion yuan. The project starts from near Duanjiazhuang Village, Tangwang Town, Licheng District, Jinan City, passes through Licheng District and Zhangqiu District of Jinan City, Zouping City of Binzhou City, Gaoqing County of Zibo City, and ends at Gaoqing to Guangrao Expressway. The design speed of the project is 120 km / h, of which the starting point to the planned Yellow River Township hub section is about 28 km, using two-way six lanes, the width of the roadbed is 34.5 meters, and the planned Yellow River Township hub to the end section is about 65.3 km, using two-way four lanes, and the width of the roadbed is 27 meters. There are 1 special bridge, 13 bridges, 34 middle bridges, 89 culverts, 31 separate interchanges at 10 interchanges, 135 passages, 1 overpass, 2 service areas, 2 maintenance areas, 1 monitoring and communication sub-center, and 8 ramp toll stations.
The Jinan-Gaoqing Expressway project is an important part of the "Shooting Two" line in the "nine vertical, five horizontal, one ring, seven shots and multiple connections" expressway network in Shandong Province, and the project is included in the "Implementation Plan for Major Projects for the Conversion of New and Old Kinetic Energy in Shandong Province". After the completion of the project, it is of great significance to improve and optimize the layout of the expressway network in Shandong Province, improve the overall road network capacity and regional transportation conditions, enhance the radiation driving range of the Jinan Metropolitan Area, build a comprehensive transportation hub of Jinan Airport, and promote the development of the new and old kinetic energy conversion starting area in Jinan.
At the construction site, the reporter saw a section of high-speed slope full of flowers and grasses to decorate the surrounding environment very beautifully, which is the first time that the project has adopted plant fiber blanket protection technology in the construction of Shandong Expressway.
Li Zhenzheng introduced that these areas are called "slope protection magic carpet", the bottom layer of these parts is made of rice straw, flax and other plant fibers woven into the fiber blanket, the fiber blanket is sprinkled with flowers and grass seeds, relying on the fiber blanket degradation to provide nutrients, the slope can soon become a green area on the slope of the highway. The Jigao Expressway project selected more than 10 kilometers of partial slope, tried to apply plant fiber blanket protection technology, compared with the traditional arch skeleton protection technology, the construction efficiency increased by more than 3 times, but also reduced the use of cement and other engineering materials.
