可回收锚索的应用与前景分析

Application and prospect analysis of recoverable anchor cable

锚索、土钉是常见基坑支护形式,然而滞留在岩土体中既产生污染又侵犯他人地下空间,为后续工程建设留下隐患。可回收锚索既可以完成普通锚索的功能,又经济环保、不留隐患。以济南市某城中村改造村民保障用房项目为例,介绍了可回收锚索在基坑支护中的应用。通过锚索轴力监测,发现可回收锚索相对于普通锚索更加环保、节约资源、降低成本,完全可以替代普通锚索在基坑支护中的功能。

Anchor cable and soil nailing are common forms of foundation pit support,when they stay in the rock and soil,they will not only causes pollution,but also infringes other people’s underground space,leaving hidden dangers for the follow-up engineering construction.The recyclable anchor cable can not only complete the function of ordinary anchor cable,and at the same time,it is economical and environmental-friendly and no hidden danger.This paper introduces the application of recyclable anchor cable in foundation pit support by taking the reconstruction project of villagers’security house in a village in Jinan City as an example.Through the monitoring of anchor cable axial force,we can found that the recyclable anchor cable is more environmentally friendly and resource-saving than ordinary anchor cable,which can completely replace the function of ordinary anchor cable in foundation pit support.
