摘要
在泰汶地区多个岩溶发育地基高层建筑建设项目中,运用预拌干料法辅助锚杆注浆,成功解决了岩溶地基场地条件下抗浮锚杆注浆中的漏失问题,保证了锚杆注浆锚固体质量,提高了注浆效率,取得了很好的经济效益和社会效益。本文介绍了预拌干料(水泥、砂、外加剂混合物)施工法在岩溶发育漏失场地抗浮锚杆施工中的成功运用,具有较好的示范作用和参考价值。
In several high rise building construction projects with karst development foundation in Taiwen area,the pre mixed dry material method is used to assist anchor bolt grouting,which will successfully solve the leakage problem of anti floating anchor bolt grouting under the condition of karst foundation site,ensure the quality of anchor bolt grouting anchor solid,improve the grouting efficiency,and receive good economic and social benefits.In this paper,successful application of the construction method of pre mixed dry materials(cement,sand and admixture mixture)in the construction of anti floating anchor bolt in the leakage site of karst development has been introduced.It has a good demonstration and reference value.
