The completion of section 16 of Shanxi central Yellow River Diversion Project

This network (correspondent Liang Ming and Qing) on November 4, the installation of the East-West dry gate at the end of the main trunk of No. 16 section of Shanxi central Yellow River Diversion Project was completed and the gate was opened and closed successfully, which marked the safe and smooth completion of the construction task of No. 16 section of Shanxi central Yellow River diversion project undertaken by the fourth company of China Railway Erju, and created favorable conditions for the realization of the overall goal of water diversion project in Central Shanxi The main tunnel and 5 adits of No. 16 diversion tunnel of Shanxi central Yellow River diversion project undertaken by No. 4 company of

have a total length of 20.08km. During the construction process, there are some construction characteristics, such as small cross-section, large slope, deep burial, difficult ventilation, unstable geological conditions of surrounding rock in the tunnel, small working support surface, inability to use large machinery and low construction efficiency. In particular, the maximum gradient of the adit is 41% and the maximum buried depth of the main tunnel is more than 400m, which is the key control project of the whole line of the central Yellow River Diversion Project. Four adits are all constructed by winch traction and transportation, which successfully overcomes the main risk sources such as "construction difficulty and high safety risk" in the construction process.

since March 2013, the Yellow River Diversion Project Department of the fourth company has always adhered to the management concept of "no best, only better". In all aspects of project management, such as on-site coordination, image requirements, safety and civilization, quality control, scientific and technological research, it really played a leading role in the construction of the Yellow River Diversion Project in the central department and achieved good social effects And won a number of awards: 12 times received praise letters, thank-you letters and congratulatory messages from the owner in terms of good faith performance, 1 "civilized, excellent and advanced construction unit of 2013-2015" and 1 national excellent QC achievement, 2 excellent QC achievements of the group company, 3 provincial engineering methods of Sichuan Province, 2 engineering methods of the group company, 2 patent applications and other honors. Tang Jian, the project manager, was awarded by the owner“ Excellent project manager

it is understood that the Yellow River Diversion Project in the middle of Shanxi Province is one of the key projects in the 12th Five Year Plan and the largest underground water transmission project in Shanxi history. Except for four aqueducts, the project is all underground. The tunnel construction length is 492km, which is unprecedented in China. The single tunnel length is 241km, which is the most in the world. The average buried depth of the tunnel is 300m, and the maximum buried depth is 700m, which is unprecedented in China. The main line of the project takes water from the reservoir area of Tianqiao Hydropower Station. The water supply scope includes four cities and sixteen counties (urban areas). The planned annual water supply is 602 million m3. After put into use, it can effectively alleviate the drought in Shanxi Province, solve the problem of "relying on nature to eat", make Shanxi no longer suffer from the "water problem", and lay a foundation for the long-term development of industry, agriculture and economy, as well as better practice Now the joint operation and optimal allocation of the Yellow River water are beneficial to the benefit of the people and the country.
