摘要
市政道路桥梁常规设置于拥挤的闹市区,为减少施工期间对周边道路及商户的影响,保证桩基施工的质量及安全,结合场地内的复杂岩溶地质情况及现场施工进度,需快速安全实施下部桩基,形成流水作业。以广佛特大桥为例,系统介绍桥梁桩基溶洞处理施工技术应用,在质量可控及安全保障的前提下,如何快速进行施工,减少对周边交通的影响。
Municipal roads and bridges are usually located in crowded downtown areas.In order to reduce the impact on surrounding roads and merchants during construction and ensure the quality and safety of pile foundation construction,it is necessary to implement lower pile foundation quickly and safely to form running water operation in combination with complex karst geological conditions in site and construction progress on site.Taking Guangfo Bridge as an example,this paper systematically introduces the application of construction technology for treatment of karst caves in bridge pile foundation.At the same time,on the premise of quality control and safety guarantee,how to carry out construction quickly to reduce the impact on the surrounding traffic is explained.
