Project Overview

The current channel of Jiaxing section of Hangzhou Shenzhen line is classified as Class IV channel, and this time it will be upgraded to restricted Class III channel of inland rivers through reconstruction. Restricted by the current situation and planning of towns and road networks along the line, the channel of class III waterway reconstruction project of Jiaxing section of Hangzhou Shenzhen line is along the old river course, and some segments are widened, starting from Tangma Town, Tongxiang, with the starting stake number of K0+000, and passing through Tangma Town, Chongfu Town, Shimen Town, Hehuachi, Chenjiaba, Mingyang Village, Sandian Yangshubang is finally at Hongqitang at the junction of Shanghai and Zhejiang. The destination stake is K91+611. The total construction mileage is about 91.611 kilometers, including 38.81 kilometers in Tongxiang, 15.87 kilometers in Xiuzhou District, 9.08 kilometers in the Economic Development Zone, 3.88 kilometers in Nanhu District, and 23.97 kilometers in Jiashan County. The project involves five counties (districts) in Tongxiang, Xiuzhou District, Economic Development Zone, Nanhu District and Jiashan County. Jiaxing urban section is divided into Xiuzhou section, Economic Development section and Nanhu section, and its administrative boundaries are arranged with flowers along the waterway. The main construction content is: about 150 kilometers of revetment engineering, approximately 5.89 million cubic meters of earthworks, 16 bridges reconstructed after consolidation, 12 bridges demolished within the project, 24 anti-collision piers and 34 main pier protection reserved for bridges, 3 new service areas, as well as supporting projects such as navigation aids, information technology, and green landscapes along the waterway. The estimated total investment of the project is 7.798 billion yuan, and the engineering cost is 4.837 billion yuan.
