摘要
压力钢管是水电站引水发电的重要组成部件,其制造和安装一直是工程技术人员关注的重点。依托实际工程项目,提出了一种斜管段压力钢管安装方法,并对其轨道及支撑结构的强度和稳定性进行了校核计算,可为该类压力钢管的安装和制造提供参考。
Penstock is the important component of diversion type power station, and its manufacture and erection are always focused by engineering technicians. Based on the actual project, this paper proposes an erection method of beveled penstock. The checking calculation for the strength and stability of track and its support structure is conducted, which provides certain reference value for the erection and manufacture of such penstocks.
