大型预制混凝土涵管钢模板的设计与应用

Design and application of steelform work for the construction of large sized R. C. pipe culvert

大型预制钢筋混凝土涵管采用外框架、内井架、顶模推车与大块模板相结合的钢模板方案，解决了强度和刚度问题。施工中结合涵管的预制工艺制订了一套特殊程序，使各种型号、不同长度的涵管基本通用，从而保证了施工速度和工程质量。

The design and application of steel formwork with the integration method of the exteriorframe form, interior-well form, jacking and rolling form, as well as big panel form, has been used successfully for the construction of large sized R. C. pipe culvert, and, as a result, easily resolved the problems of strength and rigidity. In the meantime, during construction. by combining with a set of unique procedure and the pipe culvert's precasting technology, it has been achieved successfully for the general construction of the various types. dimensions and lengths of pipe culvert. and as a result, speedy and fine quality construction has been obtained.
