球岔是一种新型的岔管型式,具有尺寸小、结构简单、布置灵活和受力明确等优点。但球壳的制作较不便,加固梁断面较大,且常需在壳内设置导流板以减少水头损失。我国近年来已在一些工程上成功地采用了球岔,唯尚少介绍和论述的文章。本刊1980年第5期发表了倪国荣同志的“球形分岔管的内力计算”一文,对球岔的分析问题作了论述,对设计很有参考价值,是值得欢迎的。
Ball bifurcation is a new type of bifurcated pipe, with the advantages of small size, simple structure, flexible layout and definite force. However, the production of the spherical shell is less convenient, and the reinforcing beam has a larger cross section, and the baffle plate is often required to reduce the head loss. In recent years, our country has succeeded in adopting some of the projects on the ball bifurcation, with only a few articles on the introduction and discussion. The fifth issue of 1980 issue of Comrade Ni Guorong, “spherical bifurcated pipe internal force,” a paper on the analysis of the problem of bifurcation is discussed, is of great value to the design, is welcome.
