April 28 -29 2016, the fifth reservoir dam new technology promotion seminar held in Qingdao, Shandong Province. The meeting was organized by China Dams Association, China Water Conservancy Institute of Hydraulic Structure Professional Committee, Ministry of Water Resources and Hydropower Planning and Design Institute, China Hydroelectric Group Northwest Survey and Design Institute, Shanxi Province, Water Resources and Hydropower Survey and Design Institute, Liaoning Province, Water Resources and Hydropower Research China, Tsinghua University, China Ocean University, North China Water Conservancy and Hydropower University, China Gezhouba Group II Engineering Co., Ltd., China Hydropower 11 Bureau of Zhengzhou Research and Design Co., Ltd. and other units of the leadership experts, as well as hydropower construction industry engineering and technical personnel more than 200 People will attend the seminar.

   eeting on the progress of new technology of concrete face rockfill dam, high dam technology progress, concrete structure crack prevention, hydraulic concrete defect reinforcement treatment technology, underwater detection and repair reinforcement, hydraulic building inspection and evaluation, dam engineering risk Management, dam dredging and other technical issues were exchanged and discussed. (Shanghai) Co., Ltd. was invited to participate in the exhibition, and demonstrated a single-component hand-wiping thick-film polyurea, two-component spray polyurea elastomer, solvent-free tunnel bridge structural reinforcement materials and samples. The excellent performance of the product by the participants of experts and scholars, engineering and technical personnel, reservoir hydropower management personnel of great concern. SWD polyurea is widely used in the repair and reinforcement of reservoir dam, which provides a strong guarantee for the long-term safe operation of reservoir dam.
