The Tuoshan Dam, at the foot of Tuoshan Mountain of Yinjiang Town, Yinxian
County, is listed as one of the four largest irrigation projects of ancient
China (the other three are: the Zhengguo Canal, the Lingqu Canal, and the
Dujiang Dam) and now it is a key national project for cultural relics preservation.
Originally built in the Tang (833 DC), the Dam is 134.4 m in length, 4.8
m in width, and 4.8 m in height. The top of the Dam is paved with cubes
of stone and the body of the Dam is made of wood and stone. There in the
Dam was found a huge trunk of plum-wood, still solid after over one thousand
years, and it is called "the backbone of the Tuoshan Dam." In
the history of ancient China's irrigation construction, the Tuoshan Dam
created several miracles in its body's gradient, its structure of macadam
and clay, its layout of the body and its use of multistage protection and
ditch check systems. After more than 1160 years of use, the Dam is still
in good condition and plays its functions of blocking salt, storing water
and draining flood. |
