构复杂性小体积混凝土快速浇筑技术在沙沱水电站的应用

结构复杂性小体积混凝土相对配置的模板量偏大，仓面偏小，若采用传统混凝土垂直入仓方式，立模和浇筑通常需使用门（塔）机，易造成互相干扰，影响整体工序安排，最终制约浇筑速度。本文介绍了改进方法在沙沱水电站的应用，即：将立模和入仓所用设备分开，立模、钢筋一般采用门（塔）机吊运，混凝土入仓采用溜管（槽）、皮带机、缆机等，立模与浇筑于不同仓号同时施工，循环作业，最终实现混凝土的快速浇筑。此方法可供类似工程参考。

Application of the technology for rapid concrete placement of small volume concrete with structural complexity in Shatuo Hydropower Station

As the amount of the formwork used for the placement of the small volume concrete with structural complexity is correspondingly larger sometimes with smaller placing surface， and then， if the mode of the conventional vertical placement of concrete， the portal（tower）cranes are always necessary to be adopted for both the erection of formwork and the placement， for which mutual interferences often occur to impact the arrangement of the whole construction process and finally restrict the concrete placement speed. The actual relevant construction carried out during the construction of Shatuo Hydropower Station is described herein； i.e. separating the equipment for the erection of formwork and the placement， adopting the portal（tower）cranes generally for the erection of formwork and reinforcement transportation， using tipping tube（chute）， belt conveyor， cable crane， etc. for the concrete placement， simultaneously carrying out the formwork erection and concrete placement at different placing surfaces for cycling construction， finally， realizing the rapid concrete placement； from which a reference can be provided for the similar projects.
