River regulation of Anhui water

The middle reaches of Anhui, which spans shallow water and Huaihai counties, have dense tributaries, serious disasters and many disputes. The more branches of the river, the longer the dike line, the worse the dike quality and the more serious the river disaster. Blocking tributaries, strengthening dikes, and harnessing water to restore ancestors are important flood control measures after the founding of the People's Republic of China. Anhui water branch in the county runs through the polder area, and the disaster is serious when it is flooded. 195 1 In winter, the upper and lower mouth of Lingjialou River, the right branch of Saiwan Water; 1955 in winter, the entrance of Gantuzi River, the right branch of Shuitiesuo River in Xiwan, and the upper and lower mouths of Guhe River, the right branch of Shuiyu River in Anhui; /kloc-In the summer of 0/958, Tiesuo River, the right branch of Sevan River, merged; 1959 winter, the entrance of Taogou River, the right branch of Saiwan Water, and the entrance of Meihe River, the right branch of Anhui Water; 1969- 197 1 During the spring and winter, tributaries such as Henghe River, Zhifu Temple River, Niubizi River and Tangbu River were also abandoned for river regulation in Anhui.

Construction steps: First, conduct diversion for the river below Xiaoshigang, then remove the buildings above Xiaoshigang, rebuild the embankment, and then build the Wu Shiyan Reservoir.

By April of 1970, a new dike with a height of 7 meters and a length of 22.5 kilometers had been built, a new river channel with a width of 229 meters and a length of 10 kilometer had been opened, an oil dam 1 large sluice and four small sluices had been completed, and the actual earthwork was 3746 100 cubic meter, and the earthwork was 6000 cubic meters. * * * More than 200 households emigrated, more than 300 houses were relocated/kloc-0, and more than 2,000 mu of farmland were excavated.

The state has allocated 3.8 million yuan for buried hills.

After renovation, the tributaries below Xiaoshigang are unified, and the river above Xiaoshigang is 400 meters wide. Only the embankment line in the buried hill is reduced from 106.3 km to 410.3km (excluding Meihe 22.5 km embankment), and the flood control burden is reduced by 65 km. More than 59,000 mu of farmland on both sides of Anhui River in the county has got rid of the threat of "once in 20 years" flood, and snails in towns and villages such as Panpu, Meicheng and Youba have also been eliminated.
