竖井贯流式进水流道模板设计与制作

Design and Fabrication of Vertical Tubular Flow Inlet Template

竖井式贯流泵因其维护方便、运行效率高等优点,在低扬程城市防洪工程中的运用较为普遍。竖井贯流式流道的曲面复杂、质量控制点多,因此其整体模板的设计与制作是泵站土建施工工程的重点和难点。本文以常州南运河枢纽工程实践为例,介绍了竖井贯流式进水流道异形模板的设计思路和具体方案,提出竖井贯流式进水流道模板制作的一些方法和经验,特别是对流道轴孔处异形曲面模板的设计、放样和制作进行了重点阐述,旨在为今后类似工程提供参考。

Because of the advantages of easy maintenance and high operation efficiency,the Vertical tubular pump is widely used in the flood control project of the city with low head.Because of the complex curved surface and many quality control points,the design and manufacture of the framework is the key and difficult point in the construction of pump station.Take the practice of changzhou south canal control project as an example,this paper introduces the design idea and concrete scheme of the special-shaped template of the vertical shaft tubular inlet channel,In particular,the design,layout and manufacture of the special-shaped surface template at the axial hole of the runner are expounded,and puts forward some methods and share the experiences in the manufacture of the vertical shaft tubular inlet channel template,.in order to provide reference for similar projects in the future.
