摘要
结合广州金沙洲某工程实例,介绍岩溶发育地区钻孔灌注桩施工采用灌注砂浆和袖阀注浆两种方法来处理桩侧溶洞,通过高压旋喷洗孔和高压空气清孔,然后再静压注浆的方法来处理桩底溶洞的方法,为其他类似工程提供设计和施工参考。
For one case of Jinshazhou in Guangzhou in karst area,the article introduces karst cave processing methods of cast-indrilled-hole concrete pile side:grouting mortar and sleeve valve grouting,and karst cave processing methods at the bottom of cast-in-drilledhole concrete pile,through high pressure jet grouting hole cleaning and high pressure air hole cleaning,then it goes on the static pressure grouting. It is as the reference for the similar project.
