摘要
低扬程泵站进水流道和出水流道施工成形的精度和质量直接影响泵站的安全、稳定和高效运行。由于进、出水流道三维形体复杂,其施工成形的精度和质量直接受到内模成形施工方法的影响。对木模成形、钢模成形和砖模成形等3种常用的低扬程泵站流道内模成形施工流程分别进行了较为详细的分析,在此基础上从内模制作精度、施工时间、制作难易程度、拆模和成本控制等方面对3种方法进行了比较研究。
The accuracy and quality of the inlet and outlet channels of the low-lift-head pumping station directly affect the safety, stability and efficient operation of the pumping station. Due to the complex shape of the inlet and outlet passages, the accuracy and quality of the forming process are directly affected by the internal model forming method. The construction process of 3 common low-lift-head pumping station internal model forming was analyzed in detail. On this basis, the 3 methods were compared from the aspects of internal model making precision, construction time, fabrication difficulty, dismantling and cost control.
