Water Culture | Pujiang Creek well, the ancient people's drought resistance and mitigation artifact!

Ancient drought resistance and disaster reduction facilities -Pujiangxijing

Predict

During the "Eight" period

The temperature of the Yangtze River Basin is high

Less precipitation

Most areas will occur in drought

Pre -raising drought resource

Mastery to ensure

Drinking water safety in the dry area

Guarantee autumn grain crops

Irrigation water

Is one of the current work points

There are many ways to resist drought resistance

Including the construction of reservoir water storage

Construction of water diversion channels, water, water, etc.

Then in ancient times

How does the ancients fight drought?

Stream well

There is a unique form of engineering in Pujiang County, Jinhua City, Zhejiang Province -Xijing, which is used for water storage, and takes water during drought. Xijing has only discovered in Pujiang County, and has not been found in other places in China.

Xijing, also known as water compartment, stuffy pond, box, water hole, etc., is an ancient and unique water conservancy facility in some mountainous areas on the banks of the streams and the bottom of the stream. The construction history can be traced back to the Song Dynasty.

There is Gaixijing (bottom of the stream)

No Gaixijing (Creek Bank)

Xijing is located at the bottom of the river, similar to water cellar storage, which is the "bottom line" of spare water sources. Generally, there is a place where there is a gap in the river bed with water seepage, and the terrain is different in length, width, and shades. The head of the stream (the direction of Shunhe) is generally 5-20 meters, 5-8 meters wide, 1-2 meters deep, the deepest is more than 4 meters, and the irrigation area ranges from 5 to tens of acres. After investigation, Xijing in Pujiang is well preserved and can still be used today.

Xijing Tao Digging Sand

Real structure of the internal structure of Xijing

The four walls of the Xijing are made of stones and pine wood, and the barrier is made into a shaped shape. The pine wood is used as a beam pillar. In the extreme drought year, open Xijing, set up waterwheels, and irrigate water lifting.

Waterwhel

Liu Sheng Village, Yantou Town, Pujiang County, along Puyang River tributaries, built a densely dense Xijing. There are 20 streams with a total irrigation area of ​​350 acres. Among them, there is a large stream well -Shenyan water warehouse, 15 meters long, 5 meters wide, 0.8 meters deep, and 24 acres of irrigation.
