粉体喷射深层搅拌桩是国内近年发展起来的一项加固软地基的新技术，具有成本低、无振动、无噪音、无侧向挤压、无泥浆排放污染环境、施工机具相对简单、施工占地面积小、成桩效率高等优点。辽河油田设计院根据本地区岩土条件，选用普通硅酸盐水泥为投体材料，在住宅、综合楼等 The powder injection deep mixing pile is a new technology developed in recent years to strengthen the soft ground, with low cost, no vibration, no noise, no lateral extrusion, no mud discharge pollution of the environment, construction equipment is relatively simple, construction accounted for Small area, pile efficiency and other advantages. Liaohe Oilfield Design Institute selects ordinary Portland cement as the investment material according to the geotechnical conditions in the region, in residential buildings, comprehensive buildings, etc.
