Compact sandy-pebble layer dynamic grouting curing construction method
The invention discloses a compact sandy-pebble layer dynamic grouting curing construction method and an application layer structure. The method includes the following steps that (1) a drill machine is put in place and performs hole drilling and forming to form a grouting hole; (2) a grouting pipe is prepared and buried in the grouting hole; (3) grouting and hole sealing are performed, specifically, a permeating grouting mode is adopted for grouting, and the grouting hole is sealed; (4) curtain grouting is conducted, that is, all grouting holes in a curtain are grouted to form a finally curtain; (5) a pump-in test is performed, and the anti-permeability of the cured final curtain is detected. The compact sandy-pebble layer dynamic grouting curing construction method is applicable to foundation ditch waterproof curtain construction under the hydrogeological condition with a compact sandy-pebble layer rich in flowing underground water; high strength of the compact sandy-pebble layer is avoided by means of permeating grouting; grout is good in anti-permeability after being cured after a certain time; accordingly, hydraulic connection of inside and outside of a foundation ditch is reduced, and a manual waterproof barrier is formed.
