长江流域单轴水泥搅拌桩绿色施工技术研究

Study on Green Construction Technology of Uniaxial Cement Mixing Pile in Yangtze River Basin

长江附近区域地质相对较差,地基加固普遍采用水泥搅拌桩加固,水泥搅拌桩是指软基处理的一种有效形式,是一种将水泥作为固化剂的主剂,利用搅拌桩机将水泥喷入土体并充分搅拌,使水泥与土发生一系列物理化学反应,使软土固结成具有较好的整体性、稳定性,形成一定强度的地基。为了减少土方的反复回填和开挖,进行长江流域单轴水泥搅拌桩施工技术研究,为后续项目施工提供技术经验。

The geology in the Yangtze River basin is relatively poor,and the foundation reinforcement generally uses cement mixing piles.The cement mixing pile is an effective form of soft foundation treatment.It is the main agent taking the cement as a curing agent,and utilizes a mixing pile machine to spray cement into the soil and thoroughly stir them,so that the cement has a series of physicochemical reactions with the soil,thus the soft soil consolidation has better integration and stability,and forms a foundation of a certain strength.In order to reduce the repeated backfilling and excavation of the earth work,the construction technology of uniaxial cement mixing pile in the Yangtze River basin is studied to provide technical experience for subsequent project construction.
