摘要
传统的超长混凝土防水结构设计通常需采用设置温度伸缩缝或设置后浇带来减少混凝土的收缩开裂。通过绍兴污水处理工程185.2 m×51.8 m×11.7 m超长结构曝气池的工程实例介绍不设温度伸缩缝和后浇带,采用无粘结预应力技术来解决超长结构钢筋混凝土易收缩开裂的问题以及该技术在施工中的注意事项。
Setting temperature expansion joints or post-casting strips are the traditional design to reduce the concrete cracks on the super length concrete structure.The design method for super length concrete structure without any expansion joints or post-casting strip has been introduced based on the project of Shaoxing sewage disposal basin by size of 185.2m×51.8m×11.7m.Also, the technical notice items in this construction are designated.
