Construction method for hole forming of bridge pile foundation in karst area
The invention discloses a construction method, particularly discloses a construction method for hole forming of a bridge pile foundation in a karst area, and belongs to the technical field of building engineering structure building processes. According to the construction method for hole forming of the bridge pile foundation in the karst area, the pile forming quality can be effectively improved, and hole collapse accidents are avoided in the construction process. The construction method comprises the following steps: firstly, classifying karst caves in a pore-forming area according to data information obtained by surveying; and according to different types of the karst caves, a full pile casing method, a static grouting method or a covering layer grouting consolidation method is adopted for the pile foundation holes in the corresponding karst cave areas to complete consolidation of foundations around the pile foundation holes in the karst cave areas and construction work of hole forming of the pile foundation holes in the karst cave areas.
本发明公开了一种施工方法，尤其是公开了一种用于岩溶地区桥梁桩基成孔的施工方法，属于建筑工程结构物建造工艺技术领域。提供一种能有效提高成桩质量，避免施工过程中发生坍孔事故的用于岩溶地区桥梁桩基成孔的施工方法。所述的施工方法先根据勘测获得的数据资料对成孔区域内的溶洞进行分类，再根据溶洞的不同类型对处于相应溶洞区域内的桩基孔分别采用全护筒法、静力注浆法或覆盖层注浆固结法完成该溶洞区域内桩基孔周边基础的固结以及该溶洞区域内桩基孔成孔的施工工作。
