长江水利委员会三峡工程建设监理部(以下简称“监理部”)在三峡三期工程混凝土施工中执行了“混凝土坯层覆盖时间及层间间歇期预警制度”、“混凝土温度控制预警制度”和“不良气候预警制度”,并在运用中不断细化、完善,确保了三期工程混凝土施工质量,取得了显著效果。通过监理每日检查和监理组织业主、设计和施工承建单位进行的4次大面积裂缝普查(抽查),至今未发现1条裂缝,混凝土施工质量优良,真正做到了内实外光。建立实施混凝土施工的3大预警制度是三期工程质量管理上的一种新尝试和创新,但是,从建立到实施仅有2 a多的时间,在具体实施和操作上还存在着一些不足,需要在今后的工作中不断补充、改进,以臻完善。
Yangtze River Water Conservancy Commission Three Gorges Project Construction Supervision Department (hereinafter referred to as the “Supervision Department”) in the Three Gorges Project of the third phase of the concrete construction of the implementation of the “concrete blanket coverage time and inter-interval warning system”, “concrete temperature control warning system” and “ Bad weather warning system ”, and in the use of continuous refinement and improvement, to ensure the quality of the third phase of the construction of the concrete works, and achieved remarkable results. Through the supervision of the daily inspection and supervision of the owners, design and construction contractors conducted four large-scale crack census (random inspection), so far found no one crack, concrete construction quality, really inside and outside the light. The establishment of three major early warning systems for concrete construction is a new attempt and innovation in the quality management of phase III project. However, there are still some shortcomings in the implementation and operation of the three early warning systems, We need to constantly supplement, improve and perfect in our future work.
