Drilling and grouting integrated and layered grouting repair equipment for roadbed looseness and repair method
The invention discloses drilling and grouting integrated and layered grouting repair equipment for roadbed loosening and a repair method, and belongs to the technical field of road internal disease repair. The equipment comprises a drilling and injecting sleeve, a slurry pumping system and a power system, the drilling and injecting casing pipe comprises an outer pipe, a gear, a plurality of spiral blades, a flywheel, an inner pipe, a piston chamber and a rack. The drilling and grouting casing pipe descends, the drill bit makes contact with and breaks the road surface, under the effect of the spiral blade, the outer pipe continuously drills to the preset depth position, the outer pipe does not need to be pulled out, a gear is rotated to drive a rack on the outer wall of the inner pipe to vertically move, a piston chamber reaches the damaged grouting discharge hole position, and grouting can be started. Through combination of the outer pipe and the inner pipe, combination of the grouting pipe and the drill rod is completed, drilling and grouting are integrated, and the defect that after drilling of loose soil is completed, the loose soil is scattered to the bottom of a grouting hole due to the fact that the drill rod is pulled out, and hole collapse is caused is overcome.
本发明公开了一种路基疏松的钻注一体及分层注浆修复设备及修复方法，属于道路内部病害修复技术领域。该设备包括钻注套管、浆液泵送系统和动力系统；其中，钻注套管包括外管、齿轮、若干螺旋刀片、飞轮、内管、活塞室和齿条。钻注套管下降，钻头接触并破碎路面，在螺旋刀片作用下，外管持续钻深至预定深度位置，无需将外管抽出，转动齿轮带动内管外壁齿条竖向移动，使活塞室到达病害的注浆排孔位置，即可开始注浆。本发明通过外管和内管的结合，完成了注浆管和钻杆结合，实现了钻注一体，避免了疏松土体在钻孔结束后因为钻杆的拔出而出现松散土体散落到注浆孔底部，造成塌孔的弊端。
