水利工程弧底马蹄形隧洞混凝土施工技术

Concrete Construction Technology for U-shaped Tunnel with Arc Bottom in Water Conservancy Project

对水利工程弧底马蹄形隧洞混凝土施工技术及应用进行总结,通过对施工程序调整和优化及对工艺改进及创新,总结一套水利工程弧底马蹄形隧洞混凝土施工技术及经验,对传统浇筑工艺进一步细化完善,混凝土成型尺寸及弧度、平整度等均满足规范要求,混凝土外观质量较好。

This paper summarizes the concrete construction technology and application of U-shaped tunnel with curved bottom in water conservancy project.By adjusting and optimizing construction procedures,as well as improving and innovating processes,a set of concrete construction techniques and experiences for U-shaped tunnels at the bottom of water conservancy projects have been summarized,further refining and improving traditional pouring techniques.The size,curvature,flatness,etc.of the concrete forming meet the requirements of the specifications,and the appearance quality of the concrete is good.
