Technical Field

The invention relates to the technical field of embankments, in particular to an embankment seepage-proofing structure for water conservancy.

Background

During the formation of a river, the geological conditions along the bank of the river can be changed to a certain extent due to the impact of the flowing water. In the process, the water flow continuously washes rocks on the shore, and various substances in the water continuously erode the original geological environment. With the change of thousands of years, the embankment of the river is easy to be fragile. Once special conditions such as flood, ice flood and the like occur, the river bank is easy to collapse if the reinforcement is not proper. Bank caving is generally divided into sliding type bank caving and dumping type bank caving. Both types of bank breakouts can cause river damage to various facilities along the bank of the river.

In recent years, with the continuous change of climate in China, the flow rate of rivers changes more and more frequently. As a first defense line bearing river impact, the construction quality of river banks is an important defense line for maintaining the life and property safety of people.
