1前言引岳供水取水口续建工程自岳城电站压力钢管桩号1+288.936m分叉管后取水,沿电站外墙埋地铺设DN1200mm管道至电站南院,后经消能井进入安阳市第五水厂引水马蹄涵(消力井为现浇钢筋混凝土工程)。消能井高6000mm,内径2000mm,壁厚200mm,底板300mm厚,100mm厚的C10的混凝土垫层,底板和井壁为双层配筋,混凝土标号C25。水平构造配筋直径12@200,配筋率0.25％。消力井由于其位置特殊,施工条件复杂,施工方案定为分4次浇注,先浇注底板,然后井身分3次浇注完成。
1 Foreword Yueyang Water Supply Pipeline Re-construction Project From the Yuecheng Power Station pressure pipe stakes 1 +288.936m after the water diversion pipe, laying DN1200mm pipeline along the external wall of the power station to the south yard of power station, City Fifth Waterworks Shuizhi Horseshoe Crane (Discharge wells for the cast-in-place reinforced concrete works). Energy dissipation well 6000mm, diameter 2000mm, wall thickness 200mm, floor 300mm thick, 100mm thick C10 concrete cushion, floor and shaft wall for the double reinforcement, concrete C25. Horizontal structure reinforcement diameter 12 @ 200, reinforcement rate of 0.25%. Because of its special location, the well has complicated construction conditions, the construction scheme is divided into 4 sub-stages, and the bottom plate is poured first, and then the well body is cast in 3 times.
