Grouting and Sealing Technology for Roadway Roof Water Seepage in Geological Structural Zones
Based on the engineering background of preventing and controlling roof water seepage within the influence range of Zhongliu transportation roadway fault,it was proposed to use RSS chemical grout to quickly seal the roof water seepage area.At the same time,U-shaped steel frame shed and polyurethane slurry were used to strengthen the surrounding rock support strength,avoiding the deformation of the surrounding rock and the formation of new water conducting cracks.Based on the on-site conditions,the specific grouting and sealing technology for roof water seepage was designed and applied in engineering.After on-site application,the problem of water seepage on the roof of Zhongliu transportation roadway was well solved,and the deformation of the surrounding rock of the roadway was controlled within a safe range.The adopted technical solution can meet the subsequent safety needs of Zhongliu transportation roadway.
