Nanjing jianning west road crossing the river to carry on the substantial construction stage

Set up rather, on January 9, nanjing west road river-crossing tunnels A4 encircle and hunt down construction projects achieving site, marked the project formally entered substantial construction stage, the construction site after the enclosed to realize green migration, bump geophysical exploration, change line moved three synchronization of goals, created assignments between palisade structure for the project construction, earned ReHe Road first opened in June 2022.

The A4 project is located at the intersection of Jianning Road and Rehe Road. It is arranged along the east-west direction of Jianning Road and the north-south direction of Rehe Road, and spans two intersections of Huimin Road and Rehe Road. The total construction length is 519 meters, the foundation pit width is 40 meters and the depth is 39 meters. The project has the foundation pit deep, wide, large, irregular, the structure form is changeable; It is mainly composed of silt layer and silt layer with high groundwater level. Traffic distribution, pipeline involved many times relocation; Special geographical location, high environmental protection requirements; The construction site is small and it is difficult to coordinate with several construction units at the same time. It is an ultra-wide and ultra-deep open-pit excavation foundation pit. The contract construction period is 1085 days. The implementation of the west section of Jianning Road (155 meters) and the north section of Rehe Road (147 meters) fully closed construction.

Since Nanjing Jianning West Road Crossriver Channel A4 bid entered the field, the project team has been undependable, loyal and responsible, improved station awareness, fully understood the project positioning in the new field of Nanjing Public Construction Center and the definition of the project to win the market, and formulated a series of scientific and effective work measures:

Is a rapid shift to municipal highway project management mode, actively with the owner, design, supervision, four big center docking platform, establish communication, at the same time with the adjacent to the study, to quickly adapt to public sector management system, to ensure that the system works carried out normalization, satisfies the requirement of public center management; Second is quick to open the work situation as the goal, innovative thinking, grasped the nettle and early planning, deployment, implementation of early early, actively participate in the public center prophase work, around the traffic organization scheme, greening migration, bump geophysical exploration, such as line moved to work for seamless docking, proactive, quick open the work situation, forming the ability to work; Third, according to the project contract mode, deepen the consciousness of operation and management, follow closely the optimization of technical scheme, and actively popularize and apply "four new technologies". Take the project as the breakthrough point of business operation, upgrade and refine some construction techniques and methods, optimize the space from the aspects of technical scheme, design scheme and expert demonstration, and lock the feasible results; Fourth, the implementation of the group company requirements. Facing the new construction mode and new market environment, we should build up the image and create brand in the field of Nanjing public construction center, expand the market and realize rolling operation. In the face of strong opponents, the project department clearly put forward "build thumbs engineering, power construction of new nanjing" project idea, form the "resultant force, energy, power," ascension "executive ability, learning ability and performance ability, harmony ability" 3 + 4 team building concept, giving full play to the advantages of China railway SuiDaoJu leading to create "safe, environmental protection, wisdom, humanities, quality" five demonstrative project of the integration of standardized management, cultivate a battle-hardened, winning the first-class team, creating profitable projects, build a sunshine project.
