Bidirectional mixing pile mixing head with mortar pressing action
The invention provides a bidirectional mixing pile mixing head with mortar pressing action. The bidirectional mixing pile mixing head comprises an inner drill pipe and an outer drill pipe which are coaxial. The outer drill pipe is mounted on the periphery of the inner drill pipe in a sleeving manner, and the lower part of the inner drill pipe extends outside the lower side of the outer drill pipe;the upper ends of the inner drill pipe and the outer drill pipe are separately connected to driving devices to drive the inner drill pipe and the outer drill pipe to rotate along axis, and the rotating directions of the inner drill pipe and the outer drill pipe are opposite; the inner drill pipe is provided with an inner cavity for slurry circulation; a mortar spraying port is formed in the innercavity; the mortar spraying port is located below the outer drill pipe; a plurality of lower mixing blades extending upward obliquely are further arranged on the inner drill pipe; the lower mixing blades are located below the mortar spraying port; and a plurality of upper mixing blades extending downward obliquely are arranged on the outer drill pipe. The bidirectional mixing pile mixing head ishigh in mixing efficiency and large in mixing range and can improve the pile forming quality of the mixing pile. The mixing head is high in mortar pressing ability, so that swelling of an earth surface soil mass is reduced.
本发明提出一种具有压浆作用的双向搅拌桩搅拌头，包括同轴心的内钻杆和外钻杆；所述外钻杆套装在内钻杆外周，且所述内钻杆的下部伸出至外钻杆下方；所述内钻杆和外钻杆的上端分别连接有驱动装置，驱动内钻杆和外钻杆沿轴心转动，且内钻杆和外钻杆的转动方向相反；所述内钻杆设置有用于浆液流通的内腔；所述内腔上设置有喷浆口；所述喷浆口位于外钻杆下方；所述内钻杆上还设置有多个倾斜向上延伸的下部搅拌叶片；所述下部搅拌叶片位于喷浆口下方；所述外钻杆上设置有多个倾斜向下延伸的上部搅拌叶片。本发明搅拌效率高，搅拌范围大，能够提高搅拌桩的成桩质量；搅拌头的压浆能力强，减小地表土体隆起。
