Engineering Cases

Unsaturated polyester resin concrete is a composite, material which is cross-linked and cured after mixing unsaturated polyester as a cementing agent with aggregates and fillers.It has obvious advantages over ordinary silicate concrete in mechanical strength, corrosion resistance and damping capacity, Because of its long service life, good corrosion resistance and appearance, it is used to replace the traditional reinforced concrete drainage pipe.PRCP does not need the built-in reinforcement framework, so it has high production efficiency, and does not need later maintenance. The product can leave factory after 24 hours. The compressive strength and flexural strength are more than twice that of ordinary concrete, and the maximum compressive strength can be 200MP above. The average flexural strength in 1d is 20MPa;

South-to-North Water Diversion Middle Route Water-receiving Area Water Supply Supporting Project

The middle route of the South-to-North Water Transfer Project is to transfer water from the Danjiangkou Reservoir in the upper and middle reaches of the Hanjiang River, the largest tributary of the Yangtze River, across Hubei and Henan provinces (the water source mainly comes from the Hanjiang River). The main canal is excavated at the head of the project in Xichuan County, Henan Province on the east bank of the Danjiangkou Reservoir.The main canal spans Henan, Hebei, Beijing and Tianjin provinces and municipalities directly under the central government. The water receiving areas are 14 large and medium-sized cities along the line, including Nanyang, Pingdingshan, Xuchang, Zhengzhou, Jiaozuo, Xinxiang, Hebi, Anyang, Handan, Xingtai, Shijiazhuang, Baoding, Beijing and Tianjin. Focus on solving the problem of water shortage in Henan, Hebei, Beijing, and Tianjin, and provide water for production, living, industrial and agricultural water for more than a dozen large and medium-sized cities along the route. The total area of the water supply area is 155000 square kilometers, and the total length of the main water delivery canal is 1277 kilometers., Tianjin water delivery branch line is 155 kilometers long.

Diversion Project from Yangtze River to Huaihe River

The Yangtze River to Huaihe River Diversion Project is a large-scale inter-basin water transfer project focusing on urban and rural water supply and the development of Jianghuai shipping, combined with irrigation and water replenishment and improvement of the water ecological environment of Chaohu Lake and Huaihe River. From south to north, it is divided into three sections: river diversion to nests, Jianghuai communication and river water transmission to the north. the total length of the water transmission line is 723 kilometers, including 88.7 kilometers of newly opened canals, 311.6 kilometers of existing rivers and lakes, 215.6 kilometers of dredging and expansion, and 107.1 kilometers of pressure pipelines.
