Gansu, China Network9No content provided for translation.10News Update (Northwest Corner)·Gansu Net journalist Song Fangke9Month10As reported by the reporter from the Ministry of Transport and Communications of Gansu Province, the first phase of Zhuohe Expressway project is progressing smoothly, with the total volume of the project now completed.68.4%The project is expected to be operational by the end of this year.
   Zhaohe Expressway, as part of Gansu Province's expressway network,2Horizontal importance“Vein”The completion of this project will mark an end to the counties of Lin Tan and Zhuo Ni not having access to a highway, which is of great significance for further improving the regional road network structure, strengthening national unity, and promoting tourism development.
    The expressway pavement project of the first phase of Zhuohe Expressway, constructed by the Provincial Public Transportation Construction Group, spans the main route全长73.749kmAdopting a two-way four-lane expressway standard, the designed speed is80Miles/Hours, roadbed width25.5Since the start of construction, facing numerous challenges such as tight schedules and heavy tasks, the Zhuohe project has made full use of the golden period of construction, turned the passive situation around, and ensured the smooth progress of the project. After four months of arduous efforts, the main line subgrade construction of the traffic section has been completed, and the stable subgrade has been fully connected, marking a phase achievement in the construction of the Zhuohe Phase I project and taking a solid step towards the goal of opening to traffic. To ensure construction quality and accelerate the progress, the Zhuohe project actively promotes the application of new materials, new technologies, new equipment, and new construction techniques.“Four New”Technology, where applied3DPaving technology not only overcomes issues such as steel wire sagging and sensor fluctuations during conventional steel wire hanging construction, but also...ReasonableEliminated errors associated with manual line hanging and beam installation.“Zero Downtime”“Zero Beam”。
     Adopting external funding+The Nela Template Composite Support Scheme avoids insufficient support force on both sides of the steel formwork due to the water-stabilized subgrade.“Running Model Phenomenon”Enhanced compaction of water-stabilized subgrade; utilizing synchronous paving and automatic grouting technology, it improves the issue of edge collapse in cement-stabilized gravel subgrade, resulting in a straight and aesthetically pleasing edge line for water-stabilized materials.
    Utilizing water-stabilized longitudinal joint flat vibration equipment, we treated the longitudinal overlapping joints of the two pavers to enhance the flatness, initial compaction, and uniformity of the water-stabilized joints; adopting the sliding formwork construction technique not only reduced labor input and increased construction speed but also ensured the inner strength and outer beauty of the auxiliary works, achieving the goal of cost reduction and efficiency improvement.
