摘　　要：黄河北岸荆隆宫堤段超深薄壁防渗墙,总长3188m,净深42.5m的墙段长1700m,而墙厚只有0.22m。如此薄而深的防渗墙,国内外均属罕见,施工难度很大。针对施工中出现的问题,对施工机具和施工工艺进行改进和完善。通过对该技术的总结,为超深薄壁防渗墙技术的进一步发展打下基础。Super-deep-thin seepage-protection wall on Jinglonggong Dyke along the Yellow River is 3188 meters long. The section of 42.5 meters deep is 1700 meters long, but only 0.22 meters thin. Seepage-protection wall that so thin and deep is rare both at home and abroad, which caused great difficulty in construction. Hence construction machines and technology were improved in the light of problems existed in construction. By summarize the technology, it lays a good foundation for further development of technology on super -deep -thin seepage -protection wall.
