一、前言 随着祖国各項事业的大跃进,排水工程亦同样地突飞猛进。如何在保証安全的原則下降低排水工程的造价,就成了我們排水設計工作人员急待研究解决的問題。管道的結构形式和建筑材料的采用是决定排水工程是否經济合理的关鍵,亦就是我們需要研究的中心問題。我局在解放十年中,曾选用磚拱混凝土园管、鋼筋混凝土园管及磚砌帳篷式管等十余种不同的結构形式,在結合就地取材来解决排
I. Preface As the great leap forward in various undertakings of the motherland, drainage projects have also made rapid progress by leaps and bounds.

The structure of pipelines and the adoption of building materials are the keys to determining whether the drainage works are economically reasonable and which is the central issue we need to study. During the 10 years of liberation, our bureau selected more than ten kinds of structural forms such as brick arch concrete garden pipe, reinforced concrete garden pipe and brick tent pipe, etc.,
