The Hangzhou-Shaoxing Expressway is the first project to be promoted in the outline of the Yangtze River Delta’s regional integrated development plan. The Hangzhou-Shaoxing section of the Hangzhou-Shaoxing Expressway (the Hangzhou-Shaoxing section of the Hangzhou-Shaoxing Expressway) has always adhered to the construction concept of "intelligent, fast, green, and safe", and added "Smart Security". “Supervision” improves the level of safety management and control to create a century-old quality project of Ping An.

The project starts from Nanyang Street, Xiaoshan District, Hangzhou City, passes through Xiaoshan District, Qiantang District, Keqiao District, Binhai New District, Shangyu District to the east, and finally ends at the junction of Shangyu District and Yuyao. The total length is about 53 kilometers, mainly two-way six-lane viaducts. The design speed is 120 km/h (140 km/h reserved), the total investment is 29.4 billion yuan, and the construction period is 26 months.

Green and efficient construction technology: implement factory construction of work sites, standardize the layout of on-site construction equipment, materials, safety protection, safe passages, signs, etc., formulate factory layout diagrams of work sites, build and improve a safe construction environment; at the same time, realize muck Fully reuse, full improvement of tunnels, pile cap excavation and pile foundation drilling slag on the whole line are fully improved and reused for access road filling, hub interconnection and service area backfilling.

Careful safety management system: implement five-level management, namely standardization of management behavior, standardization of safety production, normalization of safety assurance, informatization of on-site management and control, and branding of safety culture; with the help of external forces to weave a dense safety net, introduce industry integration, equipment special projects, and engineering 6 professional safety consulting services for insurance, pipe network protection, traffic organization and power safety; build a "1+1+N" smart safety supervision system to monitor and warn potential safety hazards at construction sites and propose solutions.

Smart construction throughout the entire process: implement digital management, visualize important project data and information, and associate the entire process data to achieve smart management of a tree; implement fingertip production, use Shaoxing side prefabrication plant as a pilot, and innovate streamlined intelligence The production process is optimized, and the smart access beam system is developed at the same time, which can quickly store beams and find beams through the "handheld terminal + light guidance" method; realize visual supervision and implement dynamic monitoring of the project with the help of information technology and drones.

Next, the project department of the Hangzhou-Shaoxing section of the Hangzhou-Shaoxing-Ningbo Expressway will steadily advance the pace of construction to ensure the successful completion of the annual target. Editor/Tian Zengpeng
