Abstract

The utility model provides a kind of pile making device of concrete pile, once can complete the construction of pile body pore-forming and guncreting fast, make full use of original soil to increase pile side friction, reaches the object simplifying operation, improve work efficiency, reduce costs.The technical scheme that the utility model adopts is: a kind of pile making device of concrete pile, include drilling rod and drill bit, it is characterized in that: what drill bit outer wall was provided with certain length creeps into flight, the external diameter creeping into flight successively decreases from top to bottom in sharp cone distal, the top of creeping into flight is provided with the reverse soil compaction flight of certain length, the external diameter of reverse soil compaction flight is greater than or equal to the maximum outside diameter creeping into flight, the inside of drilling rod is can the hollow pipeline of delivering concrete, and hollow pipeline is connected with the discharging opening of the bottom being arranged at drill bit.

Description

The pile making device of concrete pile
Technical field
The utility model relates to field of civil engineering, particularly relates to the construction of stake.
Background technology
In the method for processing foundation that China is current, the method of drawing hole with spiral carries out pore-forming and makes concrete pile being conventional processing method, its advantage is that the speed of fulfiling hole in soft foundation is very fast, but its shortcoming is, draw in the process in hole at spiral, the soil body in stake holes is discharged to ground off-balancesheet, does not namely well utilize original soil, also need the soil cleaning outward transport that other artificial and machinery will be discharged, cause work efficiency reduction, cost up thus.
Summary of the invention
In order to overcome defect and the deficiency of prior art, the utility model provides a kind of pile making device of concrete pile, once can complete the construction of pile body pore-forming and guncreting fast, make full use of original soil to increase pile side friction, reach the object simplifying operation, improve work efficiency, reduce costs.
The utility model solves the technical scheme that its technical problem adopts: a kind of pile making device of concrete pile, include drilling rod and drill bit, it is characterized in that: what drill bit outer wall was provided with certain length creeps into flight, the external diameter creeping into flight successively decreases from top to bottom in sharp cone distal, the top of creeping into flight is provided with the reverse soil compaction flight of certain length, the external diameter of reverse soil compaction flight is greater than or equal to the maximum outside diameter creeping into flight, the inside of drilling rod is can the hollow pipeline of delivering concrete, and hollow pipeline is connected with the discharging opening of the bottom being arranged at drill bit.
Best, in the pile making device of above-mentioned concrete pile, the above-mentioned spiral angle creeping into flight is tilted to down, creeps into the flight cutting soil body and creeps into downwards, creep into flight and upwards get out during reversion drilling rod when rotating forward drilling rod.
Best, in the pile making device of above-mentioned concrete pile, the spiral angle of above-mentioned reverse soil compaction flight tilts upward, and creep into flight and cut the soil body when creeping into downwards, reverse soil compaction flight presses down the soil body and is squeezed in hole wall by the soil body.
The beneficial effects of the utility model are, 1. disposablely complete the multiple working procedure such as drilling and forming hole, guncreting, have structure simple, work continuously, feature that work efficiency is higher; 2. not casting in whole work progress, not fetch earth, the original soil in stake holes is all expressed in hole wall, namely avoid the operation of soil outward transport clearly, significantly improve again side friction and the inter-pile soil bearing capacity of pile body, achieve many things at one stroke.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of pile making device of the present utility model, and in Fig. 1,1 is drilling rod, and 2 is drill bit, and 3 for creeping into flight, and 4 is reverse soil compaction flight, and 5 is discharging opening.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, pile making device includes drilling rod 1 and drill bit 2, what drill bit 1 outer wall was provided with certain length creeps into flight 3, the external diameter creeping into flight 3 successively decreases from top to bottom in sharp cone distal, the top of creeping into flight 3 is provided with the reverse soil compaction flight 4 of certain length, the external diameter of reverse soil compaction flight 4 is greater than or equal to the maximum outside diameter creeping into flight 3, and the inside of drilling rod 1 is can the hollow pipeline of delivering concrete, and hollow pipeline is connected with the discharging opening 5 of the bottom being arranged at drill bit 2.
