摘要
针对红花湖水库溢洪道渗水和裂缝的安全隐患,输水管涵不均匀沉降引起的水流方向的贯穿性裂缝,采用了帷幕灌浆加固和面层加铺混凝土的方案。重点对输水管涵采用了内衬DN1000钢管并灌C30自密实混凝土的加固方案,并对加固修复质量提出了控制措施,进行了过流能力复核。实现水库长期安全稳定运行的目标。
In response to the safety hazards of seepage and cracks in the spillway of Honghuahu Reservoir,as well as the penetrating cracks in the water flow direction caused by uneven settlement of the water pipe culvert,a scheme of curtain grouting reinforcement and surface layer concrete paving was adopted.The reinforcement scheme of lining DN1000 steel pipes and pouring C30 self compacting concrete was adopted for the water pipeline culvert,and control measures were proposed for the quality of reinforcement and repair,and the overcurrent capacity was reviewed.It can achieve the goal of long-term safe and stable operation of the reservoir.
