Comprehensive Construction Technology for Water Inflow Control in Weathered Silty Mudstone Foundation Pits
Water inflow from foundation pit is one of the risks of foundation pit collapse.In order to avoid foundation pit collapse,a comprehensive treatment plan of"grouting+open drainage"was proposed in view of the actual situ-ation of rapid water outflow and large water outflow in the weathered silty mudstone foundation pit,and the grou-ting position and depth were optimized and the concentration was adjusted.Well location and plan dimensions.The implementation results of the plan show that by increasing the grouting depth,densifying the grouting hole posi-tions,and adding open drainage wells,water seepage and water inflow in the foundation pit can be effectively re-duced,which is of great significance for ensuring construction safety.
