Abstract
The utility model relates to a grouting and stirring bottom expanding drill bit of a drilling and grouting pile. At present, a drill bit which can expand the section of the pipe end so as to improve the bearing capacity of the pile is not available in the construction industry. The grouting and stirring bottom expanding drill bit of a drilling and grouting pile comprises a drill bit body (1), wherein an oil cylinder (5) is installed in the drill bit body; the upper end of the oil cylinder is connected with a flange (2), and the lower end is connected with a joint (6); a clamping plate (9) is connected under the drill bit body, and a moving bottom expanding drill tip (10) is installed in the clamping plate. The product is used for simultaneously finishing drilling, expanding and grouting in the construction industry.
Description
Technical field:
The utility model relates to the drill bit that a kind of building trade is used, and is specifically related to a kind of 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 silicon drill bit is used for the boring of superfluidity silicon 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, provides a kind of drilled pressure filling pile slip casting that stake can be held section to enlarge to stir bottom expanding drill, and an increase stake end section improves the bearing capacity of stake, and realization brill, expansion, slip casting are once finished.
Above-mentioned purpose realizes by following technical scheme:
Bottom expanding drill is stirred in drilled pressure filling pile slip casting, and its composition comprises, oil cylinder is installed in the bit body, described bit body, connecting cleat below the described oil cylinder upper end adpting flange, lower end jointing, described bit body, and the subdrilling point is expanded in the installation activity in the described clamping plate.
Bottom expanding drill is stirred in described drilled pressure filling pile slip casting, and described bit body comprises steel pipe, on the described steel pipe helical blade is arranged, clutch disk below the described steel pipe.
Bottom expanding drill is stirred in described drilled pressure filling pile slip casting, and described joint is connected connecting rod with described movable the expansion between the subdrilling point.
The beneficial effects of the utility model:
The 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 point and opens, carry out the major part operation, thereby realize that brill, expansion, slip casting once finishes easy construction, increase stake end section, improved pile capacity.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment:
Embodiment 1:
Bottom expanding drill is stirred in drilled pressure filling pile slip casting, and its composition comprises, bit body 1, oil cylinder 5 is installed, described oil cylinder upper end adpting flange 2, lower end jointing 6 in the described bit body, connecting cleat 9 below the described bit body, and subdrilling point 10 is expanded in the installation activity in the described clamping plate.
Embodiment 2:
Bottom expanding drill is stirred in described drilled pressure filling pile slip casting as embodiment 1, and described bit body comprises steel pipe 3, and helical blade 4 is arranged on the described steel pipe, clutch disk 8 below the described steel pipe.
Embodiment 3:
Bottom expanding drill is stirred in 1 described drilled pressure filling pile slip casting as embodiment, and described joint is connected connecting rod 7 with described movable the expansion between the subdrilling point.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 subdrilling point 10 grooves and with bearing pin and connected.
The operating principle that bottom expanding drill is stirred in this drilled pressure filling pile slip casting 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, operation auger hydraulic system, the oil cylinder piston bar is moved down, 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 the enlarged footing body, through after the slip casting, the withdrawal of subdrilling point is expanded in activity, propose outside the hole with the auger drilling rod.
Claims (3)
1. bottom expanding drill is stirred in a drilled pressure filling pile slip casting, and it is characterized in that: its composition comprises, bit body, oil cylinder is installed, described oil cylinder upper end adpting flange, lower end jointing in the described bit body, the subdrilling point is expanded in the installation activity in the connecting cleat below the described bit body, described clamping plate.
2. bottom expanding drill is stirred in drilled pressure filling pile slip casting according to claim 1, and it is characterized in that: described bit body comprises steel pipe, on the described steel pipe helical blade is arranged, clutch disk below the described steel pipe.
