我国西部地区最大的水利工程——引大(大通河)入秦(秦王川)主干渠,经过八年奋战,于不久前贯通。工程主要在祁连山东段凿山开洞,87公里主干渠,隧洞就占75公里。工程由中、日、意三方的工程公司承包修建。三国工程队伍在一个工地上凿洞,各显其能,人称“三国演艺”。八年演艺过程所表现出来的许多问题发人深思.正如工程总指挥韩正卿对记者说的,引大工程是一部改革开放的“无字天书”,从中可以读出许多开阔眼界、发 The largest water conservancy project in western China, Yinda (Datong River), entered the Qin River (Qinwangchuan) main canal, and after eight years of hard work, it was recently completed. The project mainly drilled a hole in the eastern part of Qilian Mountains, 87 kilometers of main canal, and the tunnel accounted for 75 kilometers. The project was contracted and built by the Chinese, Japanese and Italian engineering companies. The Three Kingdoms project team drilled a hole on a construction site, each showing its ability, and it was known as the “Three Kingdoms Performing Arts.” Many issues expressed in the performing arts during the eight years have been thought-provoking. As the director of the project Han Zhengqing told reporters, the introduction of the “Great Project” is a “free word heavenly book” of reform and opening up, from which many insights can be read and issued.
