摘要
深基坑支护施工技术常见类型包括排桩支护、钢板桩支护、重力坝、土钉支护等技术,在支护过程常见问题包括开挖准备不充分,支护压力计算不准确,土石取样不准确。针对以上问题,在基坑开挖,土钉打孔,灌注浆液等方面提出技术要点,可供类似工程借鉴。
Common types of deep foundation pit support construction technologies include row pile support,steel sheet pile support,gravity dam,soil nail support,etc.Common problems in the support process include insufficient preparation for excavation and calculation of support pressure.Accurate,soil and stone sampling is not accurate.In view of the above problems,technical points are proposed in the excavation of foundation pits,drilling of soil nails,and infusion of slurry,which can be used for similar projects.
