Abstract

The utility model relates to a drill for the construction industry, in particular to a drilling grouting pile stirring expanding-bottom drill, comprising a drill body, an oil cylinder, a joint, a connecting rod and a moving expanding-bottom drill point. The drill body comprises a steel pipe, a helical blade, a flange, a circular plate and a splint. The oil cylinder is positioned in the drill body, the upper end is connected with the flange and the lower end is connected with the joint. The moving expanding-bottom drill point has two pieces, which are arranged in the splint of the lower end of the drill body. The connecting rob has two pieces. One end is inserted into a long slot of the joint and the other end is inserted into the moving expanding-bottom drill point slot. The utility model can finish drilling, expanding and grouting once, realize the expansion of pile section and improve the bearing capacity of piles.

Description

Bottom expanding drill is stirred in drilled pressure filling pile slip casting
Technical field: the utility model relates to the drill bit that a kind of building trade is used, and is specially drilled pressure filling pile slip casting and stirs bottom expanding drill.
Background technology: the drill bit that present building trade is used has: the triangle drill bit is used for the long auger pore-forming, and the drilled pressure filling pile drill bit is used for the boring of drilled pressure filling pile pore-forming, and superfluidity concrete drill bit is used for the boring of superfluidity concrete stake pore-forming.The stake of above-mentioned these three kinds of drill bit pore-formings, pile body are identical section.And building trade in construction in order to improve the bearing capacity of pile body, need a kind of drilled pressure filling pile slip casting to stir bottom expanding drill, this drill bit can hold stake section to enlarge, thereby improves the bearing capacity of stake.The drill bit that has this function does not at present still have.
Summary of the invention: the purpose of this utility model is the needs according to the building trade construction, propose a kind of drilled pressure filling pile slip casting that stake can be held section to enlarge and stir bottom expanding drill, an increase stake end section improves the bearing capacity of stake, and realization brill, expansion, slip casting are once finished.
Major technique content of the present utility model is, bottom expanding drill is stirred in this drilled pressure filling pile slip casting, by bit body, oil cylinder, joint, connecting rod, the movable subdrilling point that expands constitutes, bit body is by steel pipe, helical blade, flange, the garden dish, clamping plate are formed, helical blade is welded in outside the steel pipe, flange is welded in the steel pipe upper end, the garden dish is welded in the steel pipe lower end, clamping plate are that coil in two gardens that are welded in the steel pipe lower end, oil cylinder is contained in the bit body, its upper end is connected with flange, and the lower end is connected with joint, and movable expansion subdrilling point is two, be installed in the clamping plate below the bit body, and connect by bearing pin, connecting rod is that two one ends insert in the elongated slot of joints and with bearing pin and connect, other end insertion activity is expanded in the subdrilling point groove and with bearing pin and is connected.
Technique effect of the present utility model is, because the apex point of drill bit is two movable subdrilling points that expand, when bore operation, after being bored into projected depth, but the operating cyloinder drivening rod makes two borings expand the subdrilling points and opens, and carries out the major part operation, thereby realizes that brill, expansion, slip casting once finishes, easy construction has increased stake end section and has improved pile capacity.
Fig. 1 is a structural representation of the present utility model
1 bit body, 2 flanges, 3 steel pipes, 4 helical blades, 5 oil cylinders, 6 joints, 7 connecting rods, 8 gardens dish, 9 clamping plate, 10 movable bottom expanding drills.
Realize embodiment of the present utility model as shown in the figure.This drilled pressure filling pile slip casting is stirred bottom expanding drill and is made of bit body 1, oil cylinder 5, joint 6, connecting rod 7, the movable subdrilling point 10 that expands.Bit body 1 is made up of steel pipe 3, helical blade 4, flange 2, garden dish 8, clamping plate 9, helical blade is welded in outside the steel pipe 3, flange 2 is welded in the steel pipe upper end, garden dish 8 is welded in the steel pipe lower end, clamping plate 9 are that coil on 8 in two gardens that are welded in the steel pipe lower end, oil cylinder 5 is contained in the bit body 1, its upper end connects with flange 2, the lower end connects with joint 6, movable to expand subdrilling point 10 be two, is installed in the clamping plate 9 below the bit body, and connects by bearing pin, connecting rod 7 is that two one ends insert in the elongated slot of joints 6 and with bearing pin and connect, and other end insertion activity is expanded in the subdrilling point groove and with bearing pin and connected.
Operating principle of the present utility model is, when using, this drill bit connects with the auger drilling rod by flange, oil cylinder upper end oilhole joint connects with the auger hydraulic system, and operation auger hydraulic system moves down the oil cylinder piston bar, promoting connecting rod makes the movable subdrilling point that expands around the bearing pin rotation that connects with the bit body clamping plate, make two movable subdrilling points that expand open gradually and cut soil layer, make a bottom, hole form an enlarged footing body, after the process slip casting, the withdrawal of subdrilling point is expanded in activity, propose outside the hole with the auger drilling rod.
