摘要
根据某工程地质勘察资料和施工难点,决定采用旋挖钻机作为成孔机械,就旋挖钻机在风化岩层钻孔灌注桩施工中的应用及注意事项作了论述,以期提高成孔效率,保证施工质量。
According to an engineering geology investigation data and construction difficult,the rotating drilling rigs was chose as pore forming machine,the rotating drilling rigs application in weathered rock formation cast in place bored pile construction and matters need attention were discussed,so as to enhance pore forming efficiency and guarantee construction quality.
