Solid foundation guarantees the stableness of the high rise building. We have finished pilling work (deepest 90m) under intricate geological condition of granite and boulder (mostly ten layers),in the city of Xiamen, Fuzhou, Shenzhen and Zhuhai etc. In some Karsts topographic region such as Longgang district of Shenzhen, we embedded pile down into cavity of 20 meters deep despite various difficulties of Karsts features. To meet different requirements in industrial and civil engineering, we developed and launched new techniques and methods for foundation pilling, such as PHC pilling, vibrating stone-breaking pilling, high-pressure screw spray pilling, drilling pilling of pressured mortar with bottom expanding, which may be 3m diameter large and 4.5m diameter of the bottom.
