Middle route of South to North Water Transfer Project through Yellow River

Tunnel filled with water test succeed

China valve business network industry information, 15, with the Yellow River crossing the upstream line tunnel filled with water level to reach the design requirements, the South North Water Transfer Project in the Yellow River water filled test success. The success of the water filled test is an important milestone in the construction of the middle line project.

 Yellow River project is the key project of the Middle Route Project of South to North Water Diversion project. Yellow tunnel is the largest and most complex project of the south to North Water Diversion Project.

 Water filled test to test tunnel structure safety performance and safety assessment before operation of the project successfully put into operation to provide important support for. During the water filling test, the structural performance of the Yellow River Crossing Project and the downstream line tunnel is good, and meet the design requirements.

 Yellow River project is located in the west of Zhengzhou, about 30 kilometers west of Henan, a total length of 19.3 kilometers. The tunnel section is 4.25 kilometers long, double hole line layout, single hole diameter of 7 meters, the minimum depth of 23 meters, the use of slurry balance shield tunnel. Design flow of 265 cubic meters per second, increase the flow of 320 cubic meters per second.

 Yellow River project started construction in September 27, 2005, the construction lasted for 9 years. The success of the filling test in the Yellow River tunnel project is an important milestone in the construction of the middle line project. So far, of South to North Water Diversion Middle Route across the board with water conditions, for the smooth realization of the flood in 2014 after watering goals laid a solid foundation.
