Recently, the first phase of the Yellow River Avenue project in the starting area constructed by Jinan Urban Construction Group welcomed a key node, and the ground road of the first phase of the Yellow River Avenue project (north of Qingyin Expressway) was successfully opened to traffic, which is another key node of the project after the opening of the southern section of Qingyin Expressway on August 17, 2022. Since then, the first phase of the Yellow River Avenue project (from Sun Geng North Road to G104 section, along the current National Highway 220, with a total length of 16.2 kilometers) has realized the full line of surface roads. At present, the project is actively promoting the construction of the underground passage of the smart industrial park, and plans to complete the completion and acceptance in June this year.
The completion and opening of the ground road of the first phase of the Yellow River Avenue project will effectively connect the groups on the north bank of the Yellow River in the starting area, realize the smooth traffic connection of 15 to 25 minutes between the groups, and connect the existing and under construction multiple cross-river passages, becoming a large transportation corridor along the Yellow River to help the provincial capital Jinan support the development of the river, promote the development of resources along the line, stimulate the adjustment of industrial structure, thereby driving economic development along the line and improving the living standards of residents.
Adhere to the "project is king" and overcome difficulties to seize the progress
The construction scale of the first phase of the Yellow River Avenue project is large, the construction period is short, the groundwater level is high, the operation intensity is large, the average excavation depth of the foundation pit is about 15 meters, and the widest part of the structure is 92 meters, which involves multi-process cross operation and difficult construction organization.
During the construction process, the participating units in the northern section of Qingyin Expressway adhered to the concept of "project is king", scientifically deployed, fearless of difficulties, faced difficulties, and fought on the wall chart of the node target project headquarters, seized the golden period of construction, and reasonably deployed personnel, materials and machines into the construction of the project. More than 2,500 (more than 3,000 during peak periods) builders of the whole line, 24-hour shift operation in each post, night and day, sprint, complete about 4 million cubic meters of earthwork excavation, about 120,000 tons of steel bar binding, about 1.2 million cubic meters of concrete pouring, about 250,000 square meters of asphalt paving, and at the same time improve the supporting facilities such as street lights, traffic security and security, and successfully complete the major node goal of the ground road.
Focus on intelligent construction, scientific and technological innovation to improve efficiency
Since the beginning of the planning and construction of the first phase of the Yellow River Avenue project, it has taken the lead in practicing the concept of intelligent construction, taking the construction of the project intelligent platform as the guide, taking into account the demonstration of innovative technologies, giving full play to the leading role of informatization and digitalization in the process of engineering construction, and striving to build a system platform that integrates the application of new urban construction technology and engineering construction management.
In the construction stage, the use of digital management applications, mainly using UAV spatial data management platform, BIM+GIS management platform, Luban progress management platform and 360 panoramic space digital platform, through the whole life cycle data collection, collaborative control, in order to improve the efficiency of project construction management.
At the same time, in the construction process, a number of scientific research topics such as the research and development and application of foam lightweight soil, silt solidification technology and road performance, rotary excavation and expansion uplift pile, durable urban asphalt pavement were carried out, and the project construction was led by new technologies and new processes.
Implement green construction and practice the concept of ecological protection
The light of science and technology illuminates the road of green development, and the Yellow River Avenue is not only a road of science and technology, but also a road of green ecology. The first phase of the Yellow River Avenue project in the construction process fully practice the concept of ecological protection, the implementation of green construction, the project research and development of a kind of industrial solid waste, suitable for the Yellow Flood area of the roadbed silt green economic curing agent, the solidified silt has good mechanical properties, durability and environmental performance, can provide economic and reliable curing materials for the Yellow River Avenue silt subgrade engineering, while solving a large number of industrial solid waste disposal and engineering construction soil shortage problem, is an innovative technology to protect resources and the environment, with significant theory, Technological innovation and application promotion value.
In the next step, Jinan Urban Construction Group will continue to maintain the spirit of never slacking off and the attitude of indomitable struggle, set off a construction boom in an all-round way, complete the project nodes with high standards and high quality, and make every effort to build high-quality projects and benchmark projects that are satisfactory to the people.
