| 摘 要： | 以5000t/d熟料生产线原料立磨基础为例,简要介绍了其桩基施工和基坑开挖方案和实施情况;重点对该大体积混凝土工程的施工组织设计(包括材料选用和质量控制,混凝土配比确定,混凝土的温升控制和钢筋、模板工程要求等)以及混凝土的浇筑施工实施进行了详细介绍。该大体积混凝土立磨基础施工后检查,其表面未见有害温度裂缝存在;立磨投产2年多来,其基础及周围建筑物振动较小,较好地符合了设计和生产使用要求。

| Abstract: | The pile base construction and excavation scheme of the raw material vertical mill base of a 5 000 t/d clinker production line were introduced in brief, and the construction scheme design of the large-volume concrete project including material selecting and quality control, concrete proportion, temperature control and steel&moulding board requirements were stressed on as well as the concrete pouring situation. And after the large-volume concrete base project finished, there was no temperature-crack to be fo... |
