岳城水库供水工程贴边岔管设计

岳城水库供水工程， 邯郸、安阳两城市引水岔管均采用内、外贴边补强板型式对取水口进行局部加强。此补强方法对水流流态干扰较少， 水头损失小。设置这样的岔管对原电站压力钢管结构改动较小， 构造相对简单， 制作与安装方便， 对岳城水库供水这样的改建工程较为适用。

Design of branch pipe with welts for the Yuecheng Reservoir Water Supply Project

Both internal and external reinforcement welts are adopted for local reinforcement of the openings for diversion branch pipes to Handan and Anyang of the Yuecheng Reservoir Water Supply Project. The method disturbs the flow pattern relatively less and the water head loses in small. Such installed branch pipes, which relatively make less changes to the structures of the original penstocks and have the structure simple, as well as make the fabrication and erection convenient, is suitable to the reconstructed project such as the Yuecheng Reservoir Water Supply Project.
