现代城市市政建设中的许多工程勘察项目要对各种软土地基进行处理。石灰粉体深层喷射搅拌法加固轻建筑物的软土地基有独特功效。石灰粉体深层喷射搅拌土桩(喷粉桩)适用于软弱土层、持力层较深的轻型建筑物的地基加固。这些软土地基主要是由淤泥、淤泥质土、粘性土、粉土和杂填土构成的,含水量高,孔隙比大,抗剪强度低,压缩系数大,渗透系数小,沉降稳定时间长。喷粉桩可有效地提高地基承载力,减少沉降量,增强边坡的稳定,故适用于各类加固工程如柱下单独基础、墙下条形基础,贮罐基础、工业厂房内拥有地面
Many engineering survey projects in the construction of modern urban municipalities are required to deal with various soft grounds. The limestone deep jet mixing method has a unique effect of reinforcing the soft ground of a light building. Lime powder deep jet agitated soil piles (spray powder piles) are suitable for the foundation reinforcement of light buildings with soft soil layers and deep layers. These soft soil foundations are mainly composed of silt, silt soil, cohesive soil, silt soil and miscellaneous soil, high water content, large void ratio, low shear strength, large compression factor, low permeability coefficient, and long settling stability time. . Powder spray piles can effectively increase the bearing capacity of the foundation, reduce the settlement, and enhance the stability of the slope. Therefore, it is applicable to various types of reinforcement works such as individual foundations under columns, strip foundations under walls, and grounds in tank foundations and industrial plants.
