摘要
市政工程领域的基坑工程具有规模小、深度分布复杂、紧贴或穿越市政管线等特点,此类基坑,除常规的基坑支护保护周边环境[1]外,尚需重点处理坑内高差以及现状管线的保护问题。结合具体工程实例,探讨了复杂基坑穿越现状管线时采取的技术措施,主要是与施工相结合的设计方法以及现状管线整体考虑的保护措施,完美地解决了复杂基坑开挖时坑内高差的处理问题,同时为基坑穿越现状管线时对管线的保护提供了参考。
The foundation pit engineering in the municipal engineering field has the characteristics of small scale, complex depth distribution, closing to or crossing municipal pipelines. This kind of foundation pit is required to specially treat the height difference within the pit and the protection of the existing pipelines besides the conventional pit supporting to protect the surrounding environment. According to the detailed engineering cases, the article further discusses the technical measures to be taken when the complex foundation pit crosses the existing pipelines. The protection measures are mainly the design methods combined with the construction and the integrated consideration of the existing pipelines, which ideally solve the treatment problems of height difference within pit during the excavation of complex foundation pit, and also can be referred for the protection of pipelines during the foundation pit crossing the existing pipelines.
