人工注浆法抗浮锚杆施工技术

Artificial Grouting Anti-Floating Anchor Construction Technology

随着高层建筑的兴起,抗浮锚杆的施工也越来越多地被运用在工程中.高层建筑基础较深,地下水位较高,在富含地下水地质条件下的抗浮锚杆施工,存在着保证注浆质量及节点处的防水处理等施工难题.结合工程实例介绍了人工注浆法的施工工艺、灌注浆的模拟试验及抗浮锚杆的节点防水处理措施.实践证明,采用人工注浆法施工的抗浮锚杆,质量更加有保证,节点处防渗漏效果良好.

With the rise of high-rise buildings, anti-floating anchor construction is increasingly used in the project. It is difficult to ensure the grouting quality and nodes waterproof in the anti-floating anchor construction due to the deep foundation of high-rise buildings with high water table. This paper introduces the artificial grouting construction process, the slurry infusion simulation and anti-floating anchor node waterproof treatment according to an engineering case. Practice proves that the usage of artificial grouting construction for anti-floating anchor is capable to improve the construction quality and the nodes anti-leakage ability.
