When will the Hailing Island Bridge be opened to traffic?

The Hailing Island Bridge made a breakthrough in September. The main bridge has been fully closed and is expected to be fully completed and open to traffic in 2020. After the completion of the Hailing Island Bridge, the traffic environment of Hailing Island will be greatly improved, and travel will be more convenient for local residents.

On September 5, Guangdong Expressway Co., Ltd. announced that the Hailing Island Bridge project on the Huaiji to Yangjiang Expressway has made breakthrough progress, and the main bridge of the Hailing Island Super Bridge, a control project, has been fully closed. It has laid a solid foundation for its full completion and opening to traffic in 2020.

The closure was completed at 5 am

The main bridge of the Hailing Island Super Bridge was fully closed

The total length of the Hailing Island Bridge project route of the Huaiji to Yangjiang Expressway is 9.232 Kilometers, its control project Hailing Island Bridge has a total length of 3004 meters. The main bridge superstructure is a prestressed concrete variable-section continuous box girder. It adopts a single-box single-chamber straight web structure and a hanging basket cantilever cast-in-place construction. The right panel has been It was successfully closed on April 18 this year.

At 0:00 a.m. on the 5th, at the left closing section of the mid-span of the extra-large bridge, with the successful completion of preparatory work such as symmetrical ballast loading of water tanks, locking of external rigid support beams, and application of temporary prestressing forces, on-site workers began Pour the concrete in the Helong section. After more than five hours of intense and orderly work, at about 5 a.m. on the 5th, the last concrete pouring was completed, marking the completion of the main bridge of the Hailing Island Bridge. The project construction has made breakthrough progress, laying the foundation for the completion of the entire line by the end of this year. Base.

It is understood that the Hailing Island Bridge consists of the main bridge, the south approach bridge, and the north approach bridge, with a total length of 3,004 meters. As the most important part of the bridge, the main bridge is 208 meters long and is designed with a 500-ton navigation hole. The construction team said that now is the time when the "autumn tiger" is showing its power. The cement and steel bars have heat absorption, coupled with the reflection of sunlight from the sea, the difficulty of construction on the bridge will also increase when encountering high temperature weather.

Eight micro-innovations improve bridge durability

The main bridge of Hailing Island Super Bridge is fully integrated into the complex marine environment, which has become a major challenge for project construction. In order to ensure the structural durability and corrosion resistance of the bridge, the requirements for construction technology, raw materials and construction process control are more stringent. The Hailingdao Bridge project has always adhered to the construction concept of safety, durability, and precise management. It has taken a large number of targeted measures from design to construction, and innovatively implemented a fully automatic electric heating steam curing machine for maintenance and an automatic spraying maintenance system for the outside of the beam bottom web. 8 micro-innovations have emerged in new technologies such as maintenance, construction of offshore concrete structure formwork with permeable formwork cloth, and hanging basket reaction frame preloading, which have reduced the safety risks of manual maintenance at high altitudes at sea and ensured the maintenance effect and Durability, ensuring the service life of the bridge.

The person in charge said that the project adheres to meticulous construction and strictly controls quality management. A large number of targeted measures have been taken from raw materials, design to construction, retaining steel casings through pile foundations, pasting permeable formwork cloth, Mainly using marine concrete to improve raw materials and other measures to enhance the corrosion resistance of the structure and ensure the safety and durability of the main bridge. The design life of the main structure of the bridge is 100 years.

“After the completion of the Hailing Island Bridge, it will effectively promote the development of Yangjiang City’s tourism industry and bring greater transportation convenience to tourists and citizens entering the island.”

It is expected to be completed in 2020 Completed and open to traffic

The Hailing Island Bridge project on the Huaiji to Yangjiang Expressway is a key construction project in Guangdong Province. The southern extension line of the project starts about 1 km northwest of Pinggang Farm. It is set up to connect Yangjiang Port to Yangyang Expressway. It crosses the Pinggang Seawall and Hailing Bay waters to the south and reaches Hailing Island and Provincial Highway 277. connection. After the project is completed and opened to traffic, it will greatly improve the traffic conditions of Hailing Island, enhance the passenger flow capacity of Hailing Island, relieve the pressure on other transportation lines on Hailing Island, and also facilitate the travel of local residents, which will have a great impact on the economic and tourism development of Hailing Island. bring significant impact.

At present, 82% of the total construction volume of the Hailing Island Bridge project has been completed. The next step will be to fully enter the construction of bridge deck paving and ancillary facilities. It is expected to be completed and open to traffic by the end of 2020.
