Study on ecological restoration allocation along Jiping Canal of East Route of South-to-North Water Transfer Project;

Research on vertical seepage cutoff of channel slope of Jiping main canal in east route of south-to-north water diversion project

(1)According to the engineering geology, hydrogeology, temperature and operating conditions of Jiping Main canal, this research offers new materials and techniques of utilizing anti-seep, preventing frost heaving, and decompress

The paper,based on the actual construction,makes plans of jacking construction of large-diameter water supply pipes across main canals,introduces some specific methods and the practice shows that they are feasible and reasonable and have achieved satisfactory results.

Methods In the irrigation area of Diaoyutai reservoir in Anhui,a section of the main channel,which the mullicicide measure was imple mented according to the local plan,was selected as a trial spot.
