摘要
兰州市清华小学深基坑工程由于周围建筑物、构筑物、管线离基坑很近,施工场地狭小、塌孔严重等影响,支护桩施工困难,采取简易钢管桩+排桩组合施工方法,用泥浆护壁+超深护筒施工工艺,有效解决了施工困难,积累经验,为类似项目提供借鉴。
The deep foundation excavation project of Qinghua Primary School in Lanzhou City is due to the surrounding buildings,structures and pipelines being close to the foundation excavation,the construction site is narrow and the collapse is serious,and the construction of the support pile is difficult.The simple steel pipe pile+row pile combination construction method is adopted.The construction process of mud wall protection+ultra-deep protection tube effectively solves the construction difficulties,accumulates experience,and provides reference for similar projects.
