Chapter 2165

A thousand-mile embankment collapses because of an ant hole; this is the truth.

He looked at Su Xinghui and said, "You didn't exaggerate this, did you? Really didn't find any piping?"

Su Xinghui pointed to the trench dug at the foot of the back of the river embankment to prevent piping: "Our patrol personnel carefully check this trench day and night, and they can't see any water seepage, so naturally there will be no piping."

This trench is specially designed to prevent piping. It doesn't need to be very deep or wide. Just dig a shallow, narrow trench along the foot of the embankment. If piping occurs, water will seep out in this trench. As long as you see water seeping in the trench, and then check along the trench, you can find the location of the piping, and then you can immediately take measures to block the piping.

This method can be said to be one of the most economical, practical, and effective methods to prevent piping, and it is also a local method summarized by the people for thousands of years.

Ke Zhifang of course also understands this method, so he went down the embankment, stopped at the foot of the embankment, and began to inspect this trench.

The rain has stopped for a few days. Under the scorching sun, this trench is very dry. Ke Zhifang walked a long way along this trench and did not see a drop of water seeping out of the trench. He nodded and said, "It seems that your embankment is indeed built very solidly."

In such weather, whether water seeped into the trench or not is clear at a glance. Under such high water pressure, this embankment can stand the test without a single piping, which is really an incredible thing.

Even if the embankment is built very solidly, if there are things like ant holes, it is possible to cause piping. However, in Chongjin County, firstly, this embankment was just rebuilt, and termites did not have time to dig holes here. Secondly, the water conservancy department of Chongjin County also attaches great importance to the work of preventing termites, so on this embankment, ant holes cannot be found, so there is no piping.
