Underground pile type obstacle pulling construction method and system
The invention discloses a construction method and system for pulling out an underground pile type obstacle. The construction method comprises the following steps that a sleeve is rotated to stretch into a pile body; the rotary sleeve drives the pile body to rotate until the pile body is twisted off; the broken part of the pile body is grabbed out; the second step and the third step are repeated according to needs till the pile body is completely pulled out; the construction system comprises a sleeve, a full-slewing drilling machine, a wedge-shaped piece and a punching grab bucket. The sleeve is used for being screwed into the pile body and driving the pile body to rotate; the full-slewing drilling machine is used for driving the casing pipe to rotationally extend into the pile body and twist off the pile body; the wedge-shaped piece is used for stretching into the position between the sleeve and the pile body to fasten the sleeve and the pile body. The impact grab bucket is used for grabbing the broken part of the pile body; according to the construction method and system, pile pulling construction can be more economical, environmentally friendly, efficient and rapid, and the construction method and system are suitable for pulling construction of underground pile type obstacles and particularly suitable for pulling construction of municipal piles in complex geology.
本发明公开一种地下桩体式障碍物拔除施工方法和系统，施工方法包括以下步骤：旋转套管使其伸入到桩体内；旋转套管带动桩体旋转至桩体扭断；抓取出桩体断碎部分；根据需要重复步骤二和步骤三至桩体全部拔除；施工系统包括套管、全回转钻机、楔形件和冲抓斗；套管用于旋扭至桩体内，并带动桩体旋转；全回转钻机用于驱动套管旋转伸入到桩体内，并扭断桩体；楔形件用于伸入到套管与桩体之间，紧固套管与桩体；冲抓斗用于抓取出桩体断碎部分；本发明的施工方法和系统能够使得拔桩施工更加经济环保、高效快捷，适用于地下桩体式障碍物的拔除施工，尤其适用于复杂地质的市政桩体的拔除施工。
