Novel foundation treatment method utilizing waste for collapsible loess
The invention provides a novel foundation treatment method utilizing waste for collapsible loess. According to the method, once drilling is performed through piles thrusted-expanded with column-hammer, the coal mine waste, namely, coal gangue serves as main padding, the power plant waste, namely, coal ash and a small number of cement, gravel and water are added, ramming-filling treatment is performed, and therefore collapsibility is eliminated, and meanwhile the bearing capacity of a foundation is substantially improved. The method is suitable for construction sites with coal mines rich in coal gangue within 50 KM from the peripheries and can be applied to foundation treatment of high-rise buildings or heavy-load industrial buildings. In collapsible loess areas, especially self-weight collapsible loess areas, the method has obvious comprehensive benefits and is worthy of wide popularization.
