溢洪隧洞底板混凝土施工技术剖析

Exploration for Concrete Construction Technology of Spillway Tunnel Slab

溢洪隧洞最早运用于水利工程,其主要功能是及时输水或泄洪,保持水电站在安全稳定的环境下完成电力生产活动。底板混凝土施工是项目建设的一个难点,施工单位需灵活运用各项技术改善水工建筑的结构性能。近年来,小型溢洪隧洞在净水厂工程建设中的运用逐渐普及,充分发挥了排水、泄水的功能作用。文章以苏州市相城水厂为案例,分析了溢洪隧洞底板混凝土施工的相关问题,对水工建筑施工技术的优化改进总结其经验。

Spillway tunnel is used earliest in water conservancy project, its main function is to timely delivery or release flood water and maintain hydropower station in safe and stable state for the completion of power production activity. Slab concrete construction is the difficult point for a project, and the construction unit should make flexible use of various techniques to improve the performance of hydraulic structures. In recent years, the small spillway tunnels are popularized step by step in water purification plant project construction, giving a full play for the functions of drainage water and discharge. Taking Xiangcheng water plant in Suzhou City as an example, the related issues for the concrete construction of spillway tunnel slab are analyzed, providing rich experiences for the optimization of hydraulic structures construction technique.
