摘要
广州白云国际机场综合交通枢纽项目所在场区溶(土)洞较发育,对其地下工程的施工质量和安全影响较大。考虑到本工程地质条件差、排桩桩间净距小、大体积混凝土结构底板阻碍信号传输等困难,经过综合分析与比较,确定水平对拉锚索施工采用预埋工艺,并阐述了施工步骤及施工注意事项。在该技术中,锚索安装无需成孔,更可实现全过程可视化预埋及安装,保证了施工质量,也确保了基坑安全。
The integrated transportation hub project of Guangzhou Baiyun International Airport is located in the area where the dissolved soil cave is relatively developed,which has a great influence on the quality and safety of the underground construction.Considering the poor engineering geological conditions,small pile spacing and large volume concrete floor structure impede signal transmission difficulties,through comprehensive analysis and comparison,the level of cable construction using embedded technology is determined,and the construction steps and notices are expounded.In the technology,the anchor cable installation needs no hole,and it can realize the visualization,embedment and installation of the whole process,which guarantee the construction quality and ensure the safety of the foundation excavation.
