【摘要】 为方便施工、排水通畅、有利运行,要求把岔管布置为平底。笔者提出的平底等截面钢岔管,除满足平底布置外,从主管到岔管布置为接近等截面过渡,以期减小水头损失,改善结构应力,这是一种新型的钢岔管。文章仅就其体型特征和体型计算作一介绍,供同行继续探讨。更多还原

【Abstract】 the bifurcated penstock with flat floor is required to design in order to construct conveniently,drain smoothly and transport easily.In this paper,the proposed bifurcated penstock with flat floor and equal section,besides the arrangement of the flat floor,is with transition of approaching equal section from the main penstock to the bifurcated penstock so as to reduce the head loss and improve the structural stress.This is a new bifurcated penstock.Therefore,its outline characteristics and calculation are introduced for further discussion.更多还原
