深层搅拌桩主要是利用水泥作为固化剂,通过深层搅拌桩机,在地基深处的土层中就地将软土和水泥浆液强制搅拌,由此所产生的一系列物理化学反应,使软土硬结成具有整体性、水稳定性和一定强度的加固体,从而提高地基强度和增大变形模量。这种软基处理方法速度陕、效果好、造价低,近几年在公路、铁路、土建及电厂等大面积软地基处理施工中应用很广泛。
Deep mixing pile is mainly the use of cement as a curing agent, through the deep mixing pile machine, in the deep foundation of the soil in the soft soil and cement slurry forced mixing, resulting in a series of physical and chemical reactions, so that soft soil Hard to form a solid, water stability and a certain strength of the reinforcement, thereby enhancing the strength of the foundation and increase the deformation modulus. This method of soft foundation processing speed Shaanxi, good effect, low cost, in recent years in the road, railways, civil engineering and power plants and other large areas of soft ground treatment is widely used.
