It is understood that the cable-stayed bridge across the inclined pond channel of Husu lake is the widest railway cable-stayed bridge in China, with a beam width of 29.77 meters.
“The cable-stayed bridge over Xietang channel of Hu Su Hu railway is the first cable-stayed bridge with double-sided box steel-concrete composite beam in China.
In the roar of the machine, the concrete is injected into the reinforcement structure through the pipeline of the pump truck.
According to the construction period, the cast-in-situ beam of the bridge side span will be completed in May this year, the main tower will be capped in June, and the cable-stayed bridge will be closed in October.
The reporter saw on the bridge of the cable-stayed bridge across the Xietang channel of Hu Su Hu railway that the reinforcement structure of the whole beam has been laid, and the construction personnel are pouring concrete.
Yesterday (January 18), the cast-in-situ beam of the side span of the first four line railway parallel cable-stayed bridge in China, the cable-stayed bridge across the Xietang channel of Husu lake, located in Shihudang Town, Songjiang District, began to pour concrete, marking that the control bridge project with the largest span and the most difficult construction of Husu Lake railway entered the beam structure construction stage, It has laid a solid foundation for the opening of Hu Su Hu railway in July 2024.
It is also the first bridge with parallel heavy-duty Railway (freight railway) and passenger dedicated line in China.
It is a control project with the largest span and the greatest construction difficulty of Hu Su Hu railway.” Hua Shanhong, chief engineer of Shanghai Suhu railway Lot 5 Project Department of China Railway Guangzhou Engineering Bureau, told reporters that before construction, the construction unit, Shanghai Suhu railway lot V Project Department of China Railway Guangzhou Engineering Bureau, established an efficient and professional construction team, held scheme review meetings for many times, and accurately controlled each construction node.

Due to the large span of the bridge and the crossing of roads and waters in the construction, the construction is difficult and the safety risk is high.
The construction personnel plan to work continuously in about two days to complete the pouring of more than 3300 cubic meters of concrete.
The total length of the bridge is 460m, of which the main span of the bridge across the inclined pond channel is 260m.
The cast-in-situ beam on the west side of the channel was first poured on the same day, with a length of 46.4m, a width of 29.77m and a height of 3.8m.
The symmetrical structure on the east side of the channel is planned to be poured before the Spring Festival.

Among them, the side span prestressed concrete cast-in-situ beam has two sections, which are respectively located on the East and west sides of the channel.
