小浪底工程进水口引渠导墙跨越F236、F238两大断层及其间的小断层所在的冲沟，其作用是同进水塔建筑物协调运用，引导水沙在进水塔前缘形成道时针大回流，产生大的冲刷漏斗，以有效地防止进水口被泥沙淤堵和顺利地排污排漂。基础处理采用了混凝土塞与固结灌浆相结合的方法，并针对不同区段的地基优劣，采用了轻型混凝土结构、重力式挡土墙和混凝土基座堆石体等不同的结构型式，以适应复杂的地质条件。 Xiaolangdi Project inlet guide canal crossing F236, F238 two faults and the small fault where the gutter, its role is to coordinate the use of water tower structures, water and sand guide the formation of the leading edge of the intake channel large hour Reflux, resulting in a large scouring funnel to effectively prevent the inlet is silted sediment and smooth drainage bleed. The foundation treatment adopted the method of combining concrete plug and consolidation grouting, and adopted different structure types such as light concrete structure, gravity retaining wall and concrete foundation rockfill according to the advantages and disadvantages of the foundation in different sections Adapt to complex geological conditions.
