In June, the shield tunnel completed a cumulative driving distance of 728 meters, setting a new record for monthly excavation of 10 meter level mud water balance shield tunnels in China! The tunnel is constructed using both open cut and shield tunneling methods, making it the first railway tunnel in China to cross the Yangtze and Huangpu Rivers. It is also the first shield tunneling method for passenger and freight railway tunnels in soft soil areas, and the first tunnel in China to use a fully enclosed lining shield tunneling method.

The Wusongkou Yangtze River Tunnel is a controlled project of the Taicang to Situan section of the Shanghai Suzhou Tong Railway. It is located in the Pudong New Area and Baoshan District of Shanghai, crossing the Yangtze River Estuary and Huangpu River. It is a double hole single track underwater tunnel with a total length of 7.275 kilometers.

In order to accelerate the speed of shield tunneling, the project team optimized various aspects of shield tunneling construction, including transportation, and opened up the "breakthrough" for shield tunneling speed improvement: creating and innovating electric locomotives, installing flat plates and frames, achieving synchronous transportation of pipe segments with mud and water pipelines, air ducts and other materials, improving rotating cranes, and increasing the transportation time of each ring of pipe segments by 20%.
