摘要
岷江龙溪口航电枢纽工程的主体施工具有工期紧、混凝土浇筑量大、施工强度高、温控要求严格等特点。岷江流域天然砂的细度模数偏低,达到了特细砂的标准。通过对筛分系统进行设计研究,验算筛分系统的设计生产能力,设置3级破碎工艺,并采用天然砂和机制砂的精准掺配,系统整体采用环保封装,多角度综合体现了系统设计的先进性,可为同类工程提供参考。
The main construction of the Longxikou Navigation-power Junction in the Minjiang River is characterized by a tight construction period,large concrete consumption,high construction intensity,and strict temperature control requirements.The natural sand in the Minjiang River Basin has a low fineness modulus,which reaches the superfine sand standard.We study the screening system design to check the design production capacity of this system.Meanwhile,we set a three-level crushing process and design the precise blending of natural sand and machine-made sand.The environmental protection packaging is adopted in the overall system,which comprehensively reflects the progressiveness of the system design from multiple angles.Finally,the results can provide a reference for similar projects.
