1 闸门概况彰武水库溢洪道位于大坝右岸,设有五孔宽12m、高8.45m的钢丝网砼弧形闸门,最大泄量4305m~3/s。该闸于1969年建成投入运行,1992年9月检查、测试发现闸门砼裂缝、剥落等现象较为严重,已影响闸门的正常运行。1992年10月进行加固修补处理。其中5扇闸门迎水面共发现裂缝226条,且2号闸门裂缝较少些;裂缝宽度大都不超过0.2mm,个别达0.3mm;5#闸门底部发现有4处钢丝裸露,其余部位没有明显锈斑渗出的痕迹。5扇闸门的背水面砼面板、纵横梁砼保护层剥落、露筋及裂缝共460多条
1 Gate Overview Zhangwu reservoir spillway is located on the right bank of the dam, with five holes width 12m, 8.45m high steel mesh concrete arc gate, the maximum discharge of 4305m ~ 3 / s. The gate was put into operation in 1969, in September 1992 inspection, the test found that the gate concrete cracks, spalling and other phenomena is more serious, has affected the normal operation of the gate. October 1992 to strengthen the repair process. Among them, there were 226 cracks in the 5 gates facing the water surface and fewer cracks in gate 2; most of the cracks did not exceed 0.2 mm in width and 0.3 mm in width respectively; 4 steel wires were found naked at the bottom of gate 5, Exudation of traces. 5 gates of the back of the concrete panels, concrete beams spalling, a total of more than 460 ribs and cracks
