粉喷桩(深层搅拌法)作为一种地基加固方法,被一些中小城镇广泛应用,现浅谈对粉喷桩的几点认识。一、粉喷桩的适用范围与优点粉喷桩适用于各种成因的饱和软粘土、淤泥、淤泥质土、粉土以及含水量较高且地基承载力标准值不大于120kPa 的粘性土等地基。粉喷桩对软土地基加固效果明显,加固后即可投入使用,并可根据上部结构的需要,灵活地将地基加固成块状、柱状、壁状、格子状等形状。由
Powder jetting pile (deep mixing method) is widely used in small and medium-sized towns as a foundation reinforcement method. Now it is discussed several points about powder jet piles. 1. Applicable Scope and Advantages of Powder-jetted Piles Powder-jetted piles are applicable to all kinds of causes such as saturated soft clay, silt, silty soil, silt soil and cohesive soils with high water content and foundation bearing capacity not exceeding 120 kPa. . DJM piles have obvious reinforcement effect on soft soil foundation and can be put into use after reinforcement. According to the needs of superstructure, foundations can be flexibly reinforced into blocks, columns, walls, grids and other shapes. by
