Pre-formed hole vertical jacking construction method
The invention relates to a pre-formed hole vertical jacking construction method, which comprises the following steps: firstly, pre-forming a hole above a vertical jacking position of a pipeline, forming the hole by adopting slurry retaining wall hole forming (forward and reverse circulation drilling, impact hole forming and rotary drilling hole forming), long spiral drilling, dry operation hole forming and the like, then, carrying out vertical jacking, and after the pipeline is jacked, and conducting grouting filling between the hole wall of the drill hole and the outer wall of the pipeline. According to the vertical jacking construction method, the vertical jacking construction efficiency of the pipeline can be greatly improved, and the perpendicularity of the jacked pipeline can be conveniently controlled.
本发明涉及一种预成孔垂直顶升施工方法，首先，在管道垂直顶升位置上方进行预成孔，成孔方式可采用泥浆护壁成孔(正、反循环钻孔、冲击成孔、旋挖钻成孔)、长螺旋钻孔、干作业成孔等，然后，进行垂直顶升施，待管道顶升完成后，在钻孔孔壁和管道外壁之间进行注浆填充。本发明的垂直顶升施工方法可大幅度提高管道垂直顶升施工效率，便于顶升管道垂直度的控制。
