【Domestic News】Central Yunnan Water Diversion Project-Super Engineering made in China
Recently, the huge components of "Yunling" TBM which used in Central Yunnan Water Diversion Project were transported to the construction site, and with the joint efforts of the project staff, the assembly was completed as soon as possible and accelerated the speed of construction. The key project of the whole line Xianglushan Tunnel of Central Yunnan Water Diversion Project Phase I Lot 3 is undertaken by CRTG. A 9.83m diameter TBM which is the largest TBM of under construction water conservancy project. In addition to TBM, many domestic equipment are also used to assist the construction of the project.
In June, huge containers arrived one after another at the entrance of Xianglushan Tunnel of Central Yunnan Water Diversion Project. CRTG Technical director of Central Yunnan Water Diversion Project Phase I Lot 3 Xu Pengzu looks excited," When the largest components of TBM arriving, the assembly can be completed on July 20, so the construction capacity will be strengthened. "
"Yunling" is the largest diameter Open Hard Rock TBM independently developed in China with red and white. It integrates cutterhead, conveyor, support, information sensing and material transportation. Its diameter is 9.83 meters, equivalent to three stories’ height, and length is 220 meters, equivalent to eight High-speed train’s length, and weighs is 2050 tons, which is equivalent to 512 adult elephants. The general manager of CRHIC Li Jianbin said, ″The successful launch of "Yunling" create a new record for the diameter of domestic hard rock TBM, mark the further improvement of the high-end level of R&D and manufacturing of TBM, and guarantee the completion of major projects such as Central Yunnan Water Diversion Project on schedule. ″
The Central Yunnan Water Diversion Project is a landmark project among 172 major water conservancy projects in China. After the completion of the project, the water can be diverted from the main stream of Jinsha River which with full of water to the central of Yunnan Province, and alleviate the contradiction between production and domestic water use in cities in the central of Yunnan Province, improve the ecological and water environment conditions of rivers and lakes in region, and benefit 36,900 square kilometers land area and 11.12 million people.
