Rocket hammer column tamping and full tamping combined construction method
In order to solve the problems that the tamping depth of deep soil foundation dynamic tamping treatment is limited and the like, the invention provides a rocket hammer column tamping and full tamping combined construction method, holes are formed through hammering of a rocket hammer, tamping is carried out in a mode of combining the rocket hammer, column tamping and full tamping, and the shape structure characteristics of the tip end of the bottom of the rocket hammer are utilized; a deep soil foundation is tamped to form holes in a manner of forming high kinetic energy, overpressure and strong compaction by lifting a preset height, and in the process of tamped hole forming, the inner side walls of the holes are strongly compacted by virtue of the special-shaped cylindrical appearance structure characteristics of a rocket hammer body, so that soil body pores are compressed, the porosity is reduced, and the compaction degree is improved; and repeated filling, impacting and tamping are carried out in the tamping holes, and column tamping and full tamping are combined, so that the bearing capacity of the foundation is further improved, and the compaction degree and the bearing capacity of the deep soil foundation are effectively improved.
为了解决深层土地基强夯处理的夯击深度有限等问题，本发明提供了一种火箭锤柱夯满夯组合施工方法，通过火箭锤锤击成孔，采用火箭锤、柱夯以及满夯结合的形式进行夯实，利用火箭锤的底部尖端的外形结构特点，通过提升预定高度形成高动能、超压强、强挤密的方式对深层土地基夯击成孔，在夯击成孔的过程中，借助火箭锤的锤体异形圆柱式的外形结构特点，对孔内侧壁产生强烈挤密作用，进而压缩土体孔隙，降低孔隙率，提高密实程度，同时，通过在夯孔内反复填料冲击夯实，并与柱夯、满夯相结合，进一步提高了地基承载力，有效提高了深层土地基的密实程度和承载力。
