黄河堤防工程基础薄弱，各种软弱夹层、裂缝及洞穴等隐患不同程度地存在，洪水期间直接威胁两岸堤防安全。建造地下连续墙是解决黄河下游堤防渗漏问题的重要手段。目前国内应用与生产的几种地下连续墙成墙技术和设备的效率和稳定性还有待提高。文章介绍的３种国际上先进的地下连续墙成墙技术与成套设备，在造墙效率、造墙深度等重要指标上各有其特色
The embankment project of the Yellow River embankment is weak, and various hidden faults, such as cracks, caves and caves, exist in varying degrees. During the flood period, they directly threaten the embankment safety. The construction of underground diaphragm wall is an important means to solve the levee leakage in the lower Yellow River. At present, the efficiency and stability of several underground continuous walls into wall technology and equipment for domestic application and production have yet to be improved. The article introduces three kinds of internationally advanced underground wall technology and complete set of equipment, in the wall efficiency, wall depth and other important indicators have their own characteristics
