Lining Structure And Construction Methods For Yellow River Water Diversion Project Of Jiaodong, Shandong Provance

Yellow River Water Diversion Project in Jiaodong area lies east of the jiaodong water transfer main line of South-to-North Water Transfer East Route Project,which is an important component of Shandong'T' shape water transfer project and the important water infrastructure for implementation of the province of water resources optimization disposition, relieving the water resources contradiction between supply and demand in jiaodong areas and improving the local ecological environment.Jiaodong Yellow River Water Diversion Project is the largest one in shandong province. The major point of the project is cross-valley long distance water transfer.Channels as long-distance water transfer carrier. Primary address is lining problem. Lining type of Combination seepage and seepage membrane is widely used in the domestic, For the artificial construction, the question of concrete strength and the uneven of performance is existing. With the demand of the project, the problem of the lining type and construction technology of channels is continually appears. The project on channels lining type for fully design, mechanized construction and reliable operation is still need to explore and study.This study according to the point of Jiaodong Yellow River Water Diversion Project on channel leakage, Frost heaving, an in-depth study of uplift pressure-proof technology and present the fully design, mechanized construction and reliable operation channel lining type.Main studies as follows:1. According to the different climate conditions, termed, engineering geology and operating conditions, and suitable for different conditions of leakage, study the design method for anti-seepage, anti-freeze expansion and drainage pressure-relief and contrast the new material, new technical measures to propose the lining plan for anti-seepage, anti-freeze expansion, anti-uplift.2. According to the different climate conditions, termed, engineering geology and operating conditions, combined with the pattern of water transfer channels and the design for anti-seepage.anti-uplift, anti-freeze expansion, the author present the resolute plan, the conditions and construction methods for construction process and the optimal lining type.3. Analyze lining effect and anti-seepage,anti-uplift, anti-freeze expansion effect and study the comprehensive efficiency.
