我们在南通市发电厂机组软土地基加固工程中采用了振动水冲法新工艺,加固后地基承载能力比天然地基提高五倍以上。同常用软土地基加固的垫层法、砂井排水法及钢筋混凝土预制桩等方法相比,振冲法具有施工工期短,质量好,劳动力省,可以就地取材,不用钢材、木材、水泥,工效高和加固费用省等优越性。
We adopted a new vibratory water scouring process in the softening of the unit foundation of Nantong City Power Plant. After the reinforcement, the bearing capacity of the foundation is more than five times higher than that of the natural ground. Compared with commonly used soft soil foundation reinforcement cushion method, sand well drainage method and reinforced concrete prefabricated piles and other methods, vibroflotation method has a short construction period, good quality, labor force, can be drawn on the spot, without steel, wood, cement , High ergonomics, reinforcement costs, and other advantages.
