The Yangpu section of Shanghai North Crossroad has entered the construction of the main structure

Yangpu district information office said, recently, north cross channel new project Ⅵ standard work well and rack bottom pouring is completed, all marked the project has full access to the main structure construction stage, also laid a solid foundation for well under the shield. Tunnels Ⅵ north cross project is located in yangpu district, city road is located in the () to shuangyang road), blocks the total length of 565 m. After the completion of the project, it will effectively relieve the traffic pressure on the main road intersection.

On January 29th night, north cross channel new project Ⅵ standard work well and rack bottom pouring is completed, all marked the project has full access to the main structure construction stage, also laid a solid foundation for well under the shield. At that time, the super-large diameter shield tunneling machine with an outer diameter of 15.5m will advance from Huangxinglu well to Yangshupu port working well in a sharp curve way.

Tunnels Ⅵ north cross project is located in yangpu district, city road is located in the () to shuangyang road), blocks the total length of 565 m. The project mainly includes the construction of shield working shaft (open section, buried section), road, tunnel, drainage and other aspects. The depth of foundation pit of working shaft is up to 27m.

On November 14, 2020, the project officially started the deep foundation pit excavation construction, and completed the earthwork of 50000m³ in more than 60 days. Starting from January 3 this year, the first piece of floor pouring, the builders completed the task with 27 days, a total of 4120 square meters of floor pouring, the thickness of the bottom plate 1.8m. In the process of foundation pit excavation and floor pouring, two pumps are used to pour concrete simultaneously, which speeds up the construction speed.

The newly built North Crossroad is a major traffic artery crossing the northern core area of the city, starting from Beihong Road overpass in the west and ending at Zhoujiazui Road Neijiang Road in the east. The total length of the project is about 19.1 km, passing through six districts of Changning, Putuo, Jing 'an, Huangpu, Hongkou and Yangpu. It is an important part of the trunk road network of "Three Crossroads and Three Verticals" in Shanghai. After the completion of the project, it will effectively relieve the traffic pressure at the junction of the main road, help to strengthen the traffic connection of the east-west development axis, balance the traffic network and improve the reliability of the backbone road network.
