针对某超长大体积混凝土工程工期紧、防水质量要求高的特点,采用了膨胀加强带无缝连续施工技术。对该技术中补偿收缩混凝土配合比的设计思路、原材料优选、配合比试配情况、工程应用及施工要点等进行了重点介绍,实践证明,该技术节约了工期,提高了工程防水质量,对同类工程的设计和施工具有一定的借鉴价值。 Aiming at the tight construction period and the high waterproof quality requirement of a super-long volume concrete, the seamless continuous construction technology of expansion and reinforcement is adopted. In this technology, the design ideas of the proportion of shrinking concrete to be compensated, the optimization of raw materials, the matching of mix proportion, the application of engineering and construction essentials are introduced emphatically. Practice has proved that this technology saves the construction period and improves the waterproof quality of the project. The design and construction of a certain reference value.
