[0002] The stability of rock slopes has always been an important part of geotechnical engineering. In projects such as highways, railways, and water conservancy projects in mountainous areas and plateaus, the seepage points of rock slopes not only affect the stability of the slopes, but may also lead to further degradation of the slopes and even geological disasters such as landslides and collapses.

[0003] Traditional rock slope repair solutions usually use steel plates or plugging materials to directly seal the leakage points. However, after the plugging is completed, water accumulates at the plugging point, which will cause the slope pressure on the plugging position and even the surrounding area to increase, leading to unpredictable serious consequences. In addition, in many cases, when the water flow is large, the solidification speed of the plugging material is insufficient and it is easily washed out by the water flow, making it difficult to guarantee the plugging effect.
