摘要
广州亚运城市政道路项目中,采用综合管沟的形式将电信电缆、10 kV电力电缆、市政给水管、高质水管、回用水管、真空垃圾管、热水管、交通信号控制线、燃气管、110 kV高压电缆等各种市政管线集中于一体。综合管沟部分的地基处理是该工程的关键。介绍了换填垫层法、水泥土搅拌桩法、高压旋喷桩法等3种方法,并就各种处理方法作了比较。
Municipal road engineering of Guangzhou Asian Games Town Project is adopting utility tunnel in which different pipelines are gathered such as telecommunication cable,power cable of 10 kV,municipal service pipe,high quality water pipe,recycling water pipe,vacuum garbage pipe,hot water pipe,traffic signal control line,gas pipe and high voltage cable of 110 kV,etc.Relevant foundation treatment about the utility tunnel is regarded as the key point of this project.There are 3 treatment methods introduced and compared in this paper,replacement & cushion method,cement mixing pile method and high-pressure rotary grouting pile method.
