地下室结构内设置塔吊施工技术应用

建筑施工过程中，塔吊的设置需考虑多方面因素，尤其对建筑外观形式特殊及施工场地狭小的工程，往往需将塔吊设置在建筑结构内部．针对地下室结构内设置塔吊施工时，将遇到的位置选择、防水处理、拆除加固等问题，结合某高层住宅小区实例，对相应问题进行分析，解决在市中心对狭小施工空间集约使用的问题，对其他类似工程起到借鉴作用．

Application of the tower cranes in underground structure technology

During the process of construction, the tower crane will be planned precisely and a number of factors and elements will be taken into consideration, particularly the projects of special architectural appearance and narrow construction sites for which the tower crane will be set inside the construction. The paper not only analyzes the design and installment of cranes under construction in basement as well as the waterproofing system in the construc- tion, but offers application of demolition and reinforcement of the tower cranes in under- ground structure. Besides, the analysis and theories are also applied to other similar pro- jects.
