地基处理（foundation treatment） A strong, deep foundation treatment methods commonly used foundation treatment method of consolidation, replacement cushion method, dynamic compaction method, sand pile method, vibroflotation method, cement mixing method, high-pressure jet grouting method, preloading method, compaction soil cement pile, cement fly ash gravel pile and lime pile method, method lime squeezing method and soil compaction pile, piles thrusted expanded pile method, single fluid method and alkali method of silicide. 1, deep strong ramming inside hole deep dynamic consolidation method DDC DDC foundation treatment patented new technology patent No. Z0 is the first hole in the ground tamping hammer into the hole edge feeding strong rammer or layered filling after dynamic compaction. Deep hole dynamic compaction method of DDC technology in the fifty-second Eureka World Invention Fair gold medal only won the highest award - Eureka award which is the foundation treatment technology in China so far in the world to get the. Hole deep dynamic compaction DDC technology and other technical difference is through the channel will ramming into the depth of the foundation with a heavy hammer shaped hole filler layer, super high energy bottom pressure, strong compaction of hole deep compaction operation make the hole filling along the vertical deep compaction consolidation of pile the soil around the transverse strength and compaction for different soil using different techniques to obtain the pile body, the enlarged and beaded tray shape to between pile and soil are tightly engaged between the friction resistance increases after foundation treatment overall uniform stiffness bearing capacity can be increased by 29 times higher deformation modulus of settlement deformation small is not affected by groundwater depth of foundation treatment can reach up to 30 meters. Widely applicable to thick miscellaneous fill, collapsible loess, soft soil, soil liquefaction, weathered
