Large basement anti-floating anchor rod structure and construction method
The invention relates to a large basement anti-floating anchor rod structure and a construction method. The construction method comprises the steps that anchor rod hole site measurement and soil body treatment are conducted; performing anchor rod drilling construction; performing anchor rod grouting construction; performing an anchor rod anti-pulling test; performing waterproof treatment on the anchor rod. The anchor rod guiding and positioning support has the beneficial effects that the anchor rod guiding and positioning support is adopted for guiding, positioning and mounting the anchor rod and the grouting pipe, and the mounting construction efficiency and mounting and positioning precision of the anchor rod are improved; a drill rod with a dust collection air bag is adopted for drilling construction of an anchor rod anchoring hole, and the dust collection air bag is used for collecting dust in the anchor rod drilling construction process; a steel pressing plate, a rubber pad and a soil nail are adopted to seal the hole opening of the anchoring hole of the anchor rod, so that the grouting construction quality of the anchor rod is improved; a shaped experimental device is adopted for carrying out an anchor rod anti-pulling test, a combined waterproof technology is adopted for an anti-floating anchor rod part, and the overall waterproof effect of the anti-floating anchor rod part on a bottom plate structure is improved.
本发明涉及一种大型地下室抗浮锚杆结构及施工方法，包括步骤：锚杆孔位测量及土体处理；锚杆钻孔施工；锚杆注浆施工；锚杆抗拔试验；锚杆防水处理。本发明的有益效果是：采用锚杆导向定位支架对锚杆和注浆管进行导向定位安装，提高锚杆安装施工效率和安装定位精度；采用带收尘气囊的钻杆进行锚杆锚固孔的开孔施工，收尘气囊对锚杆钻孔施工过程的灰尘进行收集处理；采用钢压板、橡胶垫和土钉对锚杆锚固孔的孔口进行密封处理，提高锚杆注浆施工质量；采用定型化实验装置进行锚杆抗拔试验，抗浮锚杆部位采用组合防水技术，提高底板结构上抗浮锚杆部位整体防水效果。
