钢筋砼双曲线冷却塔体积大,形状复杂,塔高壁薄,施工难度大,通风筒是冷却塔的外壳,也是施工难度最大的部位。我处在局发电厂的双曲线冷却塔的施工中根据工程特点,采用塔式起重机垂直提升和外附着式脚手架、内简单脚手架以及定型组合钢模板的施工方案取得了较好的技术经济效果。 该冷却塔淋水面积500m~2,塔高40m,通风筒截面最大处中心直径为28.71m,壁厚35cm,喉部中心直径为14.7m,壁厚12cm,筒顶中心直径为16.30m,壁厚12cm。 一、施工流水段的划分:筒壁采取连续施工的方法,施工中保持支三节钢模循环向上倒替地施工。当第三节钢模内灌筑好
Reinforced concrete hyperbolic cooling tower, large volume, complex shape, the tower wall thin, difficult construction, ventilation tube is the cooling tower shell, but also the construction of the most difficult parts. I was in the power plant hyperbolic cooling tower construction in accordance with the project features, the use of vertical tower crane and external attached scaffolding, simple scaffolding and the combination of fixed-form steel template construction program has achieved good technical and economic results. The cooling tower water area of 500m ~ 2, the tower height of 40m, the maximum cross-sectional area of the ventilator central diameter of 28.71m, wall thickness 35cm, throat center diameter of 14.7m, wall thickness 12cm, the center of the cylinder center diameter of 16.30m, wall Thick 12cm. First, the division of construction flow section: Cylinder wall to take continuous construction method, the construction of the branch to maintain the three steel cycle upside down construction. When the third section steel mold well
