"No rain" in the rainy season? Thinking too much, the recent sunny is just "rainfall." Starting today (17th), Zhejiang will enter a new round of precipitation concentration!

Tighten the flood prevention net and tighten the flood prevention strings. We came to the intersection of Qiantang River and its maximum tributary -Cao Ejiang -. This is also the key flood prevention and drainage areas of the summer and autumn flood season and the typhoon season every year.

Over the years, under the heavy wind, the floods in the upper reaches of the Cao Ejiang rolled downstream, but the lower reaches were supported by Qianjiang Chao Shui.

Who is like a dragon locking the tide, blocking the tide of the estuary storm internal invasion, and improving the flood prevention and drainage capacity on both sides of the strait? It is Cao'e River's gate in China, Cao'ejiang, the first river gate gate and the national (i) type water conservancy project.

During the influence of the "Fireworks" typhoon last year, it coincided with the tide flood of the Qiantang River. The tide of the gate was more than 7 meters. It encountered in 20 years and reached the second tide of history. Through scientific scheduling, the gate was running continuously for 9 consecutive days, 426 opens to open the gate, and a drainage of 1.052 billion cubic meters.

When we came to the core area of ​​Cao'ejiang's gate, we found that the "super iron man" that controlled the water and water also had the "tenderness" side: 28 -hole tide flood gates were neatly arranged on the 611 meter -long dam, a special patented structure, a special patented structure. Give it a "super power" to cope with the tide. On both sides of the dam, there is a "fishway" of one or two meters wide on the left and right, leaving the "Life Greenway" for the travelers. Combined with the regular "opening of the gate", the gate of Cao'ejiang also guarded the vitality of underwater underwater in the Qiantang River Basin.

Follow our shots and feel together!
