摘要
以成都市"虹桥工程"昭觉寺变电站-游乐园变电站220kV输变电电力通道工程、北牵引变电站-张家巷段工程为背景,对在输变电电力通道中使用预制小方涵的设计技术进行了详细阐述。论述中,对预制小方涵的截面尺寸、建筑材料、箱涵的制作过程、施工工艺等进行了针对性设计并付诸实施,实践证明预制方涵吊装方便,施工快捷,接头防水性能良好,是一种好的城市小型地下通道的结构形式,其成功经验值得在类似工程的设计和施工中推广应用。
Based on the section of Zhaojueshi substation -- Amusement Parks substation through a 220kv power channel project and normwaru suosta- tion -- Zhangjiaxiang of＂ Hongqiao Project＂ in Chengdu, design technology of precast small quadrate culvert frequently used in the power channel is e- laborated in detail. The section size, building material, making process of culvert and construction technique are pertinently designed and implemented. The results show that precast quadrate culvert is maneuverable with good waterproof performance. It is an excellent underground passage structure in city and worth popularizing its application in similar project design and construction.
