Construction method of slow-setting prestressed anti-floating anchor rod in karst micro-development area
A construction method of a slow-condensation prestressed anti-floating anchor rod in a karst micro-development area comprises the steps that cement paste with a specific water cement ratio is injected into a proven karst cave area for reinforcement, then anchor rod construction is conducted, secondary filling is conducted on a karst cave or a rock stratum fracture zone during secondary grouting of the anchor rod, and the construction efficiency is improved. The overall bearing capacity and stability of the whole foundation can be effectively improved, meanwhile, the compactness of the anchor rod is improved, the construction period can be shortened, and the construction efficiency is improved.
一种岩溶微发育地区缓凝结预应力抗浮锚杆施工方法，对已探明的溶洞区域先注入特定水灰比的水泥浆进行加固，然后再进行锚杆的施工，并在锚杆二次注浆时对溶洞或岩层破碎带进行二次填充，这可以有效提高整个地基的整体承载力和稳定性，并同时提升锚杆的密实度，还可以缩短施工工期，提高施工效率。
