摘要
小湾水电站尾水隧洞出口渐变段截面由圆形渐变为方形,再由方形渐变为城门洞型,体型复杂、断面较大、衬砌混凝土厚度较大、重量重、支撑体系要求坚固可靠。主要介绍了小湾水电站尾水出口渐变段分层分块、施工方法、施工程序以及模板制作情况,为以后同类工程施工提供一定的经验和借鉴。
In Xiaowan Hydropower Station,the section of tailwater tunnel outlet transition sections changes from round to rectangular, and then to arched shape. Its complicated shapes and large sections require thick concrete lining,which needs strong support for its heavy weight.This paper mainly intro-duces the design of delaminating and blocking,construction method and procedures,and formwork at the outlet transitional section,providing some experiences for future work.
