The construction of Xincheng Interchange is accelerated!Establish a bridge for Shenzhen's first large -scale prefabricated assembly

In -depth reporters learned from the Shenzhen Municipal Transportation Bureau that Shenzhen's first large -scale traffic bridge with prefabricated assembly technology -Xincheng Interchange and Perfecting Project is being accelerated. At present, the project's construction image progress has been completed about 75%, and pipeline relocation, roadbed filling, and bridge steel box beam installation are underway. It is expected to be opened to traffic in 2024. Xincheng Communications will realize the rapid conversion of traffic between Nanping and Baoan Avenue, which will be of great significance to strengthening Qianhai and Baoan's connection with diplomatic links.

The new city interchange and improvement project is located at the junction of Qianhai Cooperation Zone, Baoan District and Nanshan District. It is the connection point of Nanping Express (connected to Guiwan 1) and Baoan Avenue (connected to Shenzhen Avenue). The total length of the ramp is 7.46 kilometers, of which the ramp bridge Twelve, the total length of the bridge is 4,731 meters, 2 crowded flyover, and the length of the new comprehensive pipe corridor is about 278 meters.

The project involves multiple traffic roads, including Beihuan Avenue, Moon Bay Avenue, Baoan Avenue, Shennan Avenue, National Highway 107, Guiwan One Road, Nanping Expressway, etc. At the same time, various types of pipelines on the construction site and underground pipelines are densely distributed, which are intricate. schedule.

The project is the first large -scale over -the -LE bridge in Shenzhen, with a total assembly rate of 85%. Bridge pier columns and upper structures are prefabricated assembly construction, especially on the small flat curve radius radius and ramp bridge. The concrete section beam is successfully applied. The construction speed is fast, which has a small impact on traffic and meets the green environmental construction requirements. In order to ensure the successful assembly and construction of the project, Shenzhen has constructed the first bridge prefabricated component prefabricated plant in the urban area. In the factory area of ​​15,000 square meters, it can meet the needs of prefabricated pier pillars and section beam production and storage.

In addition, due to the small radius radius of the flat curve of the ramp bridge and large lines of the line, the project team can develop a dedicated section beam bridge to adapt to the minimum flat curve radius of 150 meters. Breakthrough.

It is understood that the project's newly built ramps (Guiwan all the way to Baoan Avenue), Q ramps (Guiwan all the way to Nanping Express), and H ramps (Baoan Avenue to Guiwan One Road) have completed infrastructure. The overall construction image progress is about 75%, and the pipeline relocation, roadfill filler, and bridge steel box beam installation are being carried out.

Xincheng Interchange is expected to be opened to traffic in 2024. The construction of the project has a rapid conversion of traffic between Nanping and Baoan Avenue, strengthening the connection between Diplomacy and Baoan Central District, improving the level of traffic services in the area of ​​the North Sea, and promoting the modern Hong Kong Harbor Hyundai The development of the service industry cooperation zone and the Baoan Central District is of great significance.
