Due to continuous water erosion and geological changes, the slopes of certain sections of the Beijing-Hangzhou Grand Canal collapsed and loosened, posing a serious threat to shipping safety. The bank protection project became extremely urgent. However, the narrow and rugged construction site, coupled with the requirement of uninterrupted shipping during construction, rendered conventional equipment inadequate.
