New progress in the third phase of the Ningbo section of the Hangzhou-Ningbo Expressway

At 11:00 a.m. on August 19, after 17 hours of continuous hard work, the first cast-in-place beam of the Phase III project of the Ningbo section of the Hangzhou-Ningbo Expressway was cast on the beach on the south bank of Huibieyang, and the project officially started the construction of the upper structure entity.

The main line of the sea area section of the Phase III project of the Ningbo section of the Hangzhou-Ningbo Expressway is 2,740 meters long, with a total of 112 cast-in-place beams. The first beam used a total of 180 tons of steel bars and 740 cubic meters of concrete.

“Offshore construction often faces interference from strong winds. We specially used mobile formwork with high wind resistance and stability to ensure safe and stable construction. At the same time, it is also equipped with a full hydraulic system and a monitoring system, which greatly improves the degree of automation of construction, effectively shortens the construction period, and ensures construction safety.” A relevant person in charge of Zhejiang Transportation Group introduced.

The site uses a complete set of equipment such as a leveling machine, a finishing machine, a napping machine, and a laminating machine, and a concrete intelligent temperature control system is deployed in many key locations to effectively improve the appearance quality of the concrete.

The Phase III project of the Ningbo section of the Hangzhou-Ningbo Expressway is an important part of the national expressway Hangzhou-Ningbo Expressway and an important distribution channel for Ningbo-Zhoushan Port. The main line of the project is 26.15 kilometers long and is built to the standard of a two-way six-lane expressway with a design speed of 100 kilometers per hour. The approved budget is 21.864 billion yuan, the total construction period is 48 months, and it is scheduled to be completed by the end of 2027. As of August 16, the project has completed a total investment of 7.258 billion yuan, accounting for 33.2% of the total investment of 21.86 billion yuan, and the overall progress has reached 12.8%.
