The construction of the Golden -Emperor Railway is accelerated, and the first steel beams on the entire line are completed

The Jinye Railway Route has across the construction site of the North Ring Road.

After 3 hours of meticulous construction, the first frame of the Golden -Emperor Railway was in place, laying a solid foundation for opening up the entire line beam channel, marking the important step in the construction of the Golden -Emperor Railway.

The Golden -Eunuch Railway is a national railway -level railway connecting Jinhua and Ningbo. The moving bridge project is an important part of the Golden Railway.

What is a frame pier steel beam? The steel beams of the frame pier refer to the horizontal frame between the steel beams between the two bridge pillars, so that the two bridge pier pillars can be connected.

The first frame of the Golden -Eunuch Railway is precisely hanging

The first steel beams that have been lifted this time are one of the key points that are related to the promotion of the entire beam work.

Due to the neighboring existing railway, the construction accuracy and safety protection requirements of the steel beams are extremely high. In order to ensure the safety of construction and reduce the impact of construction, the project adopts the "frame pier+steel beam" solution. It spans the existing railway 4 times. The single steel beam is about 32 meters long, 3.3 meters wide, 2.8 meters high, and weighs about 170 tons. It adopts it. 650 tons of crawler cranes for lifting operations.

According to Han Xueliang, the person in charge of the project, the silt soil layer is thick within the scope of the lifting site, the foundation is small, and the owner's arm is operated, and the largest land per square meter of land needs to carry more than 31 tons. Therefore, the construction party comprehensively adopts the foundation enhancement plan of "steel pipe pipe pipe+ steel concrete bottom plate", which not only meets the bearing capacity requirements, but also realizes the repetitive utilization of steel pipe piles.

The construction unit celebrates the successful lifting of the first cross -steel beams.

One end of the Jinye Railway is connected to the Yiyu Mainland Port, and the other end to the world's No. 1 Harbor Ningbo Zhoushan Port. It is an important node project of the “Belt and Road”. Internal intercity railway. After the opening of this Yizhouzhou Channel, the journey time from Ningbo to Jinhua was shortened to 89 minutes. The journey time from Ningbo to Yiwu was shortened to 71 minutes. It is about an hour than it is currently shortened.
