Taking the road and pipeline construction project of West extension of Fukang Road, North Road, West extension of North Road and West Extension of North Fourth Road in Nanbeikang district of Central District of Jinan City as an example, using the special-shaped cylindrical rocket hammer with small grounding area, deep hole-forming, high hole-forming efficiency and large treatment depth, according to the characteristics that the shape of rocket hammer can be changed by different soil quality, a new technology of high fill and deep foundation treatment-rocket Hammer Composite Column Full Ramming Deep Foundation Treatment Technology is developed. This technology can make holes once and fill the hammer rammer step by step. The construction efficiency is high, the compaction effect is good, and the bearing capacity of the foundation is greatly improved.
