摘要
西宁市昆仑大道西延段城市下穿地道工程施工环境复杂、工期短、体量大、任务重,通过对施工工期以及装饰装修进行综合考虑,最终采用跳仓法施工技术。探讨分析了跳仓法施工工艺在市政道路工程中的关键技术及操作要点。跳仓法工艺的应用,有效避免了后浇带所产生的各种质量通病,实现了对混凝土有害裂缝的控制,杜绝了后期渗漏隐患。
The urban underpass project in the west extension section of Xining Kunlun Avenue is featured by its complex construction environment,short construction period,large volume and heavy task.Through the comprehensive consideration of construction period and decoration,the sequence construction method is determined finally.The key technologies and operation points of the construction process of sequence method in municipal road engineering are discussed and analyzed.The application of sequence construction method can effectively avoid varieties of common quality problems caused by the post-pouring strap,which realizes the control of harmful cracks in concrete,and eliminates hidden troubles of later leakage.
