带钢筒预应力混凝土管在美英苏等国早已推广应用,而且已有相当大的发展。本文详细地介绍了这种管子的生产方法,并用价值工程观点进行了技术经济的初步论证,得出直径300～1000毫米的薄钢筒混凝土管具有一定的经济效益和实用价值。结合国情,笔者认为我国对这种管子应给以足够的重视,建议组织力量开展研究,使之在我国也能逐步得到发展。
Strip prestressed concrete pipes have been widely used in the United States, Britain, the Soviet Union and other countries, and there has been considerable development. This article introduced the production method of this kind of tube in detail, and carried on the preliminary demonstration of the technical economy from the value engineering point of view, obtained the thin steel tube concrete tube with diameter of 300-1000 millimeters has certain economic efficiency and practical value. Combined with national conditions, the author believes that our country should give enough attention to this kind of pipe, and proposes to organize the strength to carry out research so that it can gradually develop in our country.
