摘　　要：全称为大直径现浇混凝土筒桩。主要技术要点为在施工现场采用中高频振动锤+双钢管护筒+环形桩尖三个要点,使通过用定制桩架设备把底部环形密封的双钢管护筒压切或震动打入地下要求深度,再在双钢管护筒形成的环形空隙体内进行钢筋混凝土现场灌注施工,从而完成一根大直径现浇管桩。结合几个使用案例,介绍筒桩技术在软基加固工程及围护工程中的应用。显示了该技术的优越性[1]。The tubular pile is all named as the large-diameter cast-in-place concrete pile. The main technical essentials are three essentials of high-frequency vibratory hammer, double steel-pipe sleeve and annular pile toe used in the construction site. The customized pile frame equipment is used to crush, cut or vibrate the double steel-pipe sleeve with bottom ring seal into the required underground depth, and then to carry out the reinforced concrete cast-in-place construction in the annular space body formed by the double steel-pipe sleeve so as to complete a large-diameter cast-in-place pipe pile. Combined with several using cases, the article introduces the application of tubular pile technology in the soft foundation reinforcement engineering and enclosure engineering. The results show the superiority of this technology.
