Water-proof curtain for treating built loess roadbed subsidence damages

The invention provides a water-proof curtain for treating built loess roadbed subsidence damages, belongs to the technical field of roadbed reinforcement treatment, and aims to solve the technical problems that an existing collapsible loess roadbed treatment mode is poor in applicability, poor in treatment effect and the like when used for treating the built loess roadbed subsidence damages. The water-proof curtain for treating the built loess roadbed subsidence damages is composed of a plurality of compacted cement soil piles which are mutually overlapped on slope toes at two sides of an embankment, the compacted cement soil piles extend from the positions of the slope toes of the embankment downwards to underground areas with a depth h1 or h2 being 5-15 m in the vertical direction, the compacted cement soil piles are cylindrical, the diameter D of the compacted cement soil piles is 60-100 cm, and the width m of two mutually overlapped compacted cement soil piles is 13-20 cm. 本发明提供种用于处治已建黄土路基沉陷病害的隔水帷幕，属于路基加固
