Non-excavation small pipeline consolidated material obstacle removing method
The invention discloses a trenchless small pipeline consolidated material obstacle removing method which comprises the following steps: a hydraulic driving assembly provides a force for forwards jacking a consolidated material for a separated drill bit, and an output shaft drives a connecting rod to rotate so as to drive the separated drill bit to synchronously rotate to drill the consolidated material; the front drill bit assembly drills and destroys the consolidated matter to generate coarse slag, and the coarse slag is discharged to the crushing impeller assembly from the slag outlet hole of the front bottom plate for secondary crushing, so that the coarse slag becomes small and is further crushed into small slag by the rear drill bit assembly, and the small slag is discharged to the bottom of the operation pipeline from the slag discharge hole of the rear bottom plate; in the obstacle removing process, the self-adaptive balancing frame synchronously moves forwards towards the pipeline through the universal wheels; three-time smashing is achieved at the same time, the front drill bit assembly endows the advancing drill hole breaking capacity, the smashing impeller assembly endows the drilling resistance buffering and secondary smashing capacity, the rear drill bit assembly endows the drill hole further expanding and three-time smashing thorough capacity, and the self-adaptive balance frame avoids disintegrating slag obstacles in a pipeline or collapses to smoothly move in the pipeline; according to the method, obstacle clearing operation can be completed by entering the pipeline for one time.
本发明公开一种非开挖小型管道固结物清障方法，液压驱动组件向分离式钻头提供前顶固结物之力，输出轴带动连接杆旋转进而带动分离式钻头同步旋转钻动固结物；前钻头组件钻动破坏固结物产生粗渣从前底板的出渣孔排向粉碎叶轮组件进行二次粉碎使粗渣变小为碎渣再由后钻头组件进一步粉碎为小碎渣从后底板的排渣孔排到作业管道的底部；在清障过程中，自适应平衡架通过万向轮同步朝管道前行；本申请同时实现三次粉碎，前钻头组件赋予前行钻孔破坏能力，粉碎叶轮组件赋予钻动阻力缓冲及二次粉碎能力，后钻头组件赋予进一步扩大钻孔和三次粉碎彻底能力，自适应平衡架规避管道内的碎渣障碍物或坍塌处畅行于管道，本方法一次进入管道清障即可完成清障作业。
