Underwater coral sand foundation grouting method based on diffusion state identification and dynamic regulation

Abstract

The present application relates to a kind of underwater coral sand foundation grouting methods based on diffusion state identification and dynamic control, comprising: obtaining the underwater coral sand foundation characteristics of the region to be treated, and dividing grouting subarea;Determine grouting target;Select grouting material;Carry out simulation grouting experiment;The diffusion state of slurry in each grouting subarea is pre-judged and divided;Matching grouting strategy;Lay out monitoring system in the region to be treated, implement grouting action, and real-time acquisition of field formation information is carried out through monitoring system;Based on field formation information, the grouting sequence, grouting stage, grouting rhythm and grouting mode are dynamically adjusted;When reaching grouting target, stop grouting action.The present application can extract response law through simulation experiment before construction, and diffusion state is identified and dynamically matched grouting strategy in construction combined with monitoring information, so that slurry can effectively push and displace pore water in underwater coral sand foundation, and also form continuous, stable and load-bearing reinforced body.
