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, making cement earth pile with deep-layer stirring or high-pressure rotary spraying method is conventional processing method, and its advantage does not fetch earth, and well make use of original soil, and its frictional force in side-pile is larger, but due to material limit the intensity of pile body less; Concrete pile castinplace pile is also a kind of pile-type had a wide range of applications, its pile body good rigidly, and strength ratio is comparatively large, but frictional force in side-pile is not utilized completely, therefore can in conjunction with two kinds of stake advantages to improve its overall ultimate bearing capacity in the urgent need to one.More existing documents propose the combination of above-mentioned two kinds of stakes at present, but its working procedure is all first carry out the shaping of cement earth pile, then pore-forming and the construction re-starting pile body again in cement earth pile, so need multiple devices rotation to carry out, therefore cause construction complexity, work efficiency reduces, cost up.
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 cement earth pile and concrete intensive aspect, reaches 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, drill bit lower end is provided with discharging opening, it is characterized in that: the inside of drilling rod is can the hollow pipeline of delivering concrete, the feed pipe for mortar can carrying cement paste is provided with in hollow pipeline, the outer wall epimere of drilling rod is straight-bar, stage casing is provided with many stirring pieces, hypomere is provided with continuous print helical blade, helical blade from top to bottom diameter successively decreases in sharp cone distal, helical blade is provided with multiple slurry outlet, slurry outlet is connected with feed pipe for mortar, hollow pipeline is connected with the discharging opening of drill bit lower end.
Best, in the pile making device of above-mentioned concrete pile, the spiral angle of above-mentioned helical blade is tilted to down, and during rotating forward drilling rod, the helical blade cutting soil body creeps into downwards, and during reversion drilling rod, helical blade upwards gets out.
Best, in the pile making device of above-mentioned concrete pile, above-mentioned stirring piece is one chip, and the diameter at stirring piece place is equal to, or greater than the diameter at helical blade place.
The beneficial effects of the utility model are, 1. disposablely complete the multiple working procedures such as drilling and forming hole, cement injection, action of forced stirring, guncreting, have structure simple, work continuously, feature that work efficiency is high; 2. comprise the pile body of concrete intensive aspect in disposable making cement-soil pile body, bearing capacity of single pile is high, pile quality good; 3. all do not fetch earth in whole operation, well make use of original soil.
Accompanying drawing explanation
Fig. 1 is the structure chart of pile making device of the present utility model, and Fig. 1-1 faces structure chart, and upper end is sectional drawing; Fig. 1-2 is elevation cross-sectional view; Fig. 1-3 is top plan view.
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, drill bit 2 lower end is provided with discharging opening 4, the inside of drilling rod 1 is can the hollow pipeline 3 of delivering concrete, the feed pipe for mortar 8 can carrying cement paste is provided with in hollow pipeline 3, the outer wall epimere of drilling rod 1 is straight-bar, stage casing is provided with many stirring pieces 6, hypomere is provided with continuous print helical blade 5, helical blade 5 from top to bottom diameter successively decreases in sharp cone distal, helical blade 5 is provided with multiple slurry outlet 7, and slurry outlet 7 is connected with feed pipe for mortar 8, and hollow pipeline 3 is connected with the discharging opening 4 of drill bit 2 lower end.
