摘要:
针对城市中心区高层建筑绿色拆除技术亟待发展的现状,为实现土木工程可持续性的进一步提升,提出了绿色拆除须以推动拆除后废弃物的资源化进程为发展方向,剖析了城市中心区高层建筑拆除工程特点与技术难点。从结构检测、策略制定、流程设计及施工技术4个方面,构建了场地条件限定下的绿色拆除方法,探讨了施工与管理新技术以及精细化力学分析的应用场景。结合某城市中心区高层建筑拆除工程进行案例分析,采用建立的绿色拆除方法,对建筑不同高度部位设定不同拆除策略,基于结构分析结果设计合理拆除流程,分别采用切割吊装与机械破碎施工技术,完成了6层以上建筑构件的完整拆解与6层以下建筑的整体倒塌拆除。结果表明:在保证施工安全的前提下,实现了分类拆除与运输,为后续建筑固废资源化的高效开展提供了前序保障。
Abstract:
In view of the urgent need for the development of green demolition technologies for high-rise buildings in city center areas, in order to achieve further improvement of sustainability, authors proposed that green demolition must be developed to promote the reclamation of waste after demolition. The characteristics and main challenges of the high-rise building demolition projects in city center areas were analyzed. From four aspects including structure inspection, strategy formulation, process design and construction technology, the targeted green demolition method was established, and the applications of new construction and management technologies and the refined mechanical analysis were discussed. A case study was then conducted based on a specific high-rise building demolition project in a city center area. The green demolition method proposed in this study was adopted. Different demolition strategies were set for the building parts of different heights, and a reasonable demolition process was designed based on the results of structural analysis. The cutting and hoisting technology and the mechanical crushing demolition technology were respectively adopted to achieve the deconstruction of the building parts above the 6th floor and the collapse of the parts below the 6th floor. The results show that under the premise of ensuring safety, the demolition and transportation by category are also implemented, which provides pre-order guarantee for the subsequent waste reclamation process.
