摘要
采用钻探孔与灌浆相结合的办法探查南水北调中线干线鹤壁段总干渠施工过程中遇到的人工掏砂洞,结果表明该办法可行,其中灌浆探查是发现掏砂洞的主要途径,其次是钻孔直接探明;改性水泥粘土复合浆液结石体强度可以满足设计要求,结石体与掏砂洞洞体胶结紧密,无脱空情况。
Artificial sand-dig holes are detected at Hebi main canal of the Middle Route of South-North Water Transfer Project using drilling and grouting.The results indicate this method is feasible.Grouting exploration is the main way to detect such holes followed by drilling.Stone made of modified cement-clay grout meets design requirements and such stone cements closely with sand-dig hole with no void.
