Bidirectional cement mixing pile composite soil consolidation foundation device
The bidirectional cement mixing pile composite soil consolidation foundation device comprises an outer drill rod, the upper end and the lower end of the outer drill rod are connected with a first inner drill rod and a second inner drill rod through bearings correspondingly, first conical teeth are arranged on the upper side of the interior of the outer drill rod, and an integrated first connecting block is arranged at the upper ends of the first conical teeth; the outer side of the first connecting block is fixedly connected with the inner wall of the lower end of the first inner drill rod, and second conical teeth are arranged on the lower side in the outer drill rod. According to the drilling device, the first conical teeth, the second conical teeth and the third conical teeth are arranged, the outer drilling rod, the first inner drilling rod, the second inner drilling rod, the upper two-way stirring blades and the lower two-way stirring blades are arranged, the third conical teeth rotate to drive the first conical teeth to rotate reversely and drive the second conical teeth to rotate forwards at the same time, and then the first inner drilling rod rotates reversely and the second inner drilling rod rotates forwards; namely, the upper bidirectional stirring blade and the lower bidirectional stirring blade rotate bidirectionally to achieve stirring work, and meanwhile the drill bit rotates forwards to achieve ground breaking work.
本发明公开了一种双向水泥搅拌桩复合土加固地基装置，包括外钻杆，所述外钻杆上下端分别通过轴承连接有第一内钻杆与第二内钻杆，且外钻杆内部上侧设置有第一锥形齿，所述第一锥形齿上端设有一体的第一连接块，所述第一连接块外侧与第一内钻杆下端的内壁固定连接，所述外钻杆内部下侧设置有第二锥形齿。本发明，设置了第一锥形齿、第二锥形齿、第三锥形齿、外钻杆、第一内钻杆、第二内钻杆、上双向搅拌叶片、下双向搅拌叶片，第三锥形齿转动同时带动第一锥形齿反向转动，第二锥形齿正向转动，进而第一内钻杆反向转动，第二内钻杆正向转动，即上双向搅拌叶片、下双向搅拌叶片双向转动实现搅拌工作，同时钻头正向转动实现破土工作。
