你们要赞美耶和华!从天上赞美耶和华,在高处赞美他!他的众使者都要赞美他!他的诸军都要赞美他!日头月亮,你们要赞美他!放光的星宿,你们都要赞美他!天上的天和天上的水,你们都要赞美他!愿这些都赞美耶和华的名!因他一吩咐便都造成。
诗篇 148:1-5

Construction of China's longest undersea subway tunnel completed
1/21/2020


QINGDAO, Jan. 20 (Xinhua) -- Construction of the longest undersea subway tunnel in China was completed Monday in Qingdao, a coastal city in Shandong Province.

The 5.4-km-long tunnel, between the stations of Dayang and Qingdao North, is part of the Subway Line No. 8 project in Qingdao.

The eastern side of the tunnel was dug by the slurry shield method, while the western side by the mining method, said Wang Zili, chief engineer of the project with the China Railway Group, the company responsible for the construction.

Multiple measures, including the utilization of a robotic arm, were adopted to avoid water and mud bursts, Wang said.

The tunnel has surpassed the cross-sea tunnel of the Qingdao's Subway Line No. 1, which has 3.49 km of the line undersea, becoming the longest undersea subway tunnel in China, according to the China Railway Group and the Qingdao Metro Group, operator of the subway lines.

The Subway Line No. 8, which will run 61.4 km with 18 stations designed, will connect the international airport of Jiaodong and railway stations of Jiaozhou North, Hongdao and Qingdao North, linking the city proper of Qingdao, the economic zone of Hongdao and the city of Jiaozhou.
