Abstract
A process for grouting a super-thin curtain with polymer, includes: forming a series of V-shaped injecting holes by direct pushing method using a special drilling tool along a dam or dike axis spacedly at a predetermined distance; and injecting a two-component polymer composition into each of the holes, wherein the mixed polymer material expends and coagulates under chemical reaction to form a series of super-thin curtain segments, and the curtain segments connect with each other end to end to form a continuous and impermeable polymer curtain.
