October 19, 2011, from the home Dam hydroelectric power station Engineering construction department learned that our company is responsible for manufacturing and installation of 31 kilometers of belt conveyor line, since the start of production on June 28, 2007, in the operation of up to 4 years did not occur a safety liability accidents, did not affect the dam pouring gravel supply, It is ensured that the concrete construction of the dam hydropower station has climbed the peak and created a miracle.
To the domestic dam hydropower station is the third major hydropower project under construction in China, and its concrete pouring quantity is about 14 million cubic meters, of which the main project concrete is about 1220 cubic meters. In order to select high quality gravel aggregate, to the home Dam hydroelectric power station project headquarters through a multiparty survey, the final determination of 59 kilometers away from the dam site (a straight distance of about 30 kilometers) of the Taiping material field for the concrete aggregate source. However, how to transport aggregate to the dam area has become a major problem, the traditional automobile transportation has environmental protection, economy, safety and other problems. After in-depth study and demonstration, the project headquarters of Mayanpo Hydropower station adopted our company Belt Conveyor Transportation scheme-using belt conveyor to transport the semi-finished aggregate of Taiping material mining and processing to the dam area, the gravel processing system.
Long distance Belt Conveyor line total length of 31.1 kilometers, from 5 first and last connected, through 9 tunnels of belt conveyor composition, the design of the delivery capacity of 3000 tons per hour. To the main concrete pouring peak of the dam hydropower station long duration, the maximum pouring strength of about 450,000 cubic meters/month, sandstone aggregate transport volume is large and concentrated, long-distance belt conveyor has a large span, single-line layout, complex operating conditions, high reliability requirements, difficult management and so on.
In order to protect the lifeline of this project to the construction of the hydroelectric power station, our company has made considerable efforts in the design and production of this project: by the chief Engineer Shan Hinglong, the design of the conveyor line to carry out a full range of considerations, taking fully into account the operation and management needs of the user, and has sent a number
Through our joint efforts with the project headquarters of the hydroelectric power station, long-distance belt conveyor has performed well over the years, including December 2010, the delivery of semi-finished aggregate 1.57 million tons, the month supply of finished aggregate 1.538 million tons, the highest daily supply of 65,000 tons, set the world's highest production supply of artificial gravel aggregate, It has made outstanding contributions to the peak of concrete pouring in the dam hydropower station.
