Abstract
The utility model discloses a forced cutting drill bit for a soft foundation cast-in-situ pile. The forced cutting drill bit comprises a drill bit waistband. The drill bit waistband comprises a circular supporting plate and a plurality of conical ribs which are downwards arranged along the vertical direction of the circular supporting plate. The conical ribs converge at a vertex. The conical ribs are provided with a plurality of groups of alloy teeth which are staggered up and down along concentric circles at different heights. A guide and positioning round steel block is arranged at the vertex of the conical ribs. The forced cutting drill bit has the advantages that a soil body can be rapidly, uniformly and forcibly cut in a layered way at the same time when cast-in-situ pile holes are formed to achieve the goal of quick hole formation, the engineering construction progress is accelerated and the expenses in manpower and material resources are reduced.
Description
Technical field
The utility model relates to a kind of cut drill, and particularly a kind of soft foundation castinplace pile is forced cut drill.
Background technology
At present, conventional castinplace pile in pore forming process, drill bit commonly used in the soft foundation pore-forming through regular meeting occur in creep in the clod separation inhomogeneous, clod cuts disengaging time in creeping into longer, and wrap up in the phenomenon of brill.After this phenomenon takes place, Kong Weihou cleaning drill bit drilling rod all need be proposed, descend the drilling rod pore-forming after cleaning out again.Sometimes has crept into to 40-50m the position, hole, drilling rod is all proposed after the time longer, increased time of pouring pile hole, wasted great amount of manpower.
The utility model content
For overcome the cutting of clod in the existing castinplace pile drill bit pore forming process inhomogeneous take place wrap up in the brill phenomenon, the utility model provides a kind of soft foundation castinplace pile to force cut drill, it utilizes at drill bit many row's carbide buttons is set, every row's carbide button forms several concentric circles at cutting zone, so that the soil body can be cut rapidly and uniformly, reach the purpose of fast pore-creating in pore forming process.This drill bit is the interior earth of quick cutting hole to greatest extent, can also improve the construction effect of pouring pile hole greatly.
The technical solution of the utility model is as follows:
A kind of soft foundation castinplace pile is forced cut drill, it comprises a drill bit waistband, described drill bit waistband comprises a circular base slab, and along downward several taper muscle that arrange of the vertical direction of described circular base slab, described those taper muscle converge at a summit;
Described those taper muscle are provided with some groups of carbide buttons along the concentric circles of its differing heights, form dislocation up and down;
The summit of described taper muscle is provided with the guide-localization round steel.Wherein, described guide-localization round steel is used in drilling process guiding and location, and described some groups of carbide buttons are used for the fast hierarchical cutting soil body.
Preferably, described carbide button is welded on the described taper muscle.
In an embodiment of the present utility model, described taper muscle arranges three, and the concentric circles of those its differing heights of taper muscle upper edge arranges three groups of carbide buttons that misplace up and down.In pressure cut drill of the present utility model, the quantity of carbide button can change by the quantity of selection carbide button group and the quantity of taper muscle, usually can carry out the quantity selection of carbide button according to soil property, for example in cohesive soil, carbide button quantity can be suitably increased, in sandy soil layer, then carbide button quantity can be suitably reduced.
The soldering angle of described carbide button can be adjusted according to the soil property of construction plant, and when soil property was hard, carbide button interior welding in the past arranged that when soil property was softer, carbide button can be arranged toward external welding.The soldering angle of carbide button can be perpendicular to ground, perhaps is an angle with ground.
Compared with prior art, the beneficial effects of the utility model are as follows:
The utility model is welded on castinplace pile drill bit carbide button respectively on the concentric circles of drill bit different-diameter, form dislocation up and down, after row's carbide button cuts a part of soil body, another row's carbide button can force to be cut to another part soil body, by that analogy, can when pouring pile hole, reach the purpose of forcing fast evenly the layered cutting soil body, can fast pore-creating, accelerate the engineering construction progress, reduce the expenditure of manpower and materials.

The specific embodiment
The utility model provides a kind of soft foundation castinplace pile to force cut drill, it is welded on castinplace pile drill bit carbide button respectively on the concentric circles of drill bit different-diameter, form dislocation up and down, after row's carbide button cuts a part of soil body, another row's carbide button can force to be cut to another part soil body, by that analogy, reach the purpose of evenly forcing the layered cutting soil body fast.
The below is further described the utility model with specific embodiment by reference to the accompanying drawings.
Embodiment
Referring to Fig. 1 and Fig. 2, a kind of soft foundation castinplace pile of present embodiment is forced cut drill, comprise a drill bit waistband 1, drill bit waistband 1 comprises a circular base slab 11, and along downward three the taper muscle 12,13,14 that arrange of the vertical direction of this circular base slab 11, those taper muscle converge at a summit;
Those taper muscle are provided with three groups of carbide buttons that misplace up and down 21,22,23 along the concentric circles of its differing heights;
The common vertex of those taper muscle is provided with guide-localization round steel 3.
Usually, carbide button 21,22,23 adopts welding manner to be connected on the taper muscle 12,13,14.
Wherein, guide-localization round steel 3 is used in drilling process guiding and location, and three groups of carbide buttons 21,22,23 are used for the fast hierarchical cutting soil body.
The pressure cut drill of the soft foundation pouring pile hole of present embodiment, be that castinplace pile drill bit carbide button is welded on respectively on the concentric circles of drill bit different-diameter, form dislocation up and down, after row's carbide button cuts a part of soil body, another row's carbide button can force to be cut to another part soil body, by that analogy, and to reach the purpose of evenly forcing the layered cutting soil body fast, can accelerate the engineering construction progress, reduce the expenditure of manpower and materials.
When the geology situation changes, at different soft foundations, can reach the purpose of forcing the cutting soil body by adjusting the method for carbide button quantity or adjustment carbide button soldering angle.As in cohesive soil, can suitably increase carbide button quantity, in sandy soil layer, then can suitably reduce carbide button quantity.The quantity of carbide button specifically can change by the quantity of selection carbide button group and the quantity of taper muscle.
In the present embodiment, the quantity of taper muscle and carbide button group all is set to three, and in other embodiment of the present utility model, the quantity of taper muscle and carbide button group can be chosen according to actual conditions, can select to be less than or more than three.
At different soft foundations, can also adjust the carbide button soldering angle, when soil property was hard, carbide button interior welding in the past arranged that referring to Fig. 3, when soil property was softer, carbide button can be arranged toward external welding, referring to Fig. 4.Therefore, the soldering angle of carbide button can be perpendicular to ground, perhaps is an angle with ground.
