Concrete arch bridge anchor rod frame beam construction method
The invention discloses a concrete arch bridge anchor rod frame beam construction method, and relates to the technical field of frame beam construction. The invention discloses a construction method. The method comprises the steps of measuring, paying off and slope brushing, anchor hole site measuring and lofting, drilling platform building, drilling machine drilling, hole cleaning, anchor rod hole inspection, anchor rod body manufacturing and installing, grouting, prestress tensioning, frame beam grooving, frame beam steel bar frame manufacturing, formwork installing, concrete pouring, sealing, concrete curing and turf filling. By the adoption of the construction technology, grouting reinforcement measures are conducted on the roots of the anchor rods, the anchored side slope is solidified preferentially, the side slope reaches a stable state under the self-weight effect, then free end tensioning is conducted, it is guaranteed that the anchor rod frame beam is stable, and the whole side slope is in a balanced and stable state all the time.
本发明公开了一种混凝土拱桥锚杆框架梁施工方法，涉及框架梁施工技术领域。施工方法包括：测量放线刷坡→锚孔孔位测量放样→搭建钻进平台→钻机钻进→清孔→锚杆孔检验→锚杆杆体制作及安装→注浆→预应力张拉→框架梁挖槽→制作框架梁钢筋框架→模板安装→混凝土浇筑→封口→混凝土养生→填充草皮。通过采用本施工工艺，对锚杆根部进行注浆加固措施，使锚固边坡优先进行固化，在自身自重作用下使边坡达到稳定状态，再进行自由端张拉，保障了锚杆框架梁稳定，使整个边坡始终处于一种平衡稳定状态。
