Embodiment
In order that those skilled in the art more fully understand the technical scheme in the application, it is real below in conjunction with the application
The accompanying drawing in example is applied, the technical scheme in the embodiment of the present application is clearly and completely described, it is clear that described implementation
Example only some embodiments of the present application, rather than whole embodiments.It is common based on the embodiment in the application, this area
The every other embodiment that technical staff is obtained under the premise of creative work is not made, it should all belong to the application protection
Scope.
As shown in Fig. 1 ~ 5, a kind of quick piling equipment, including the pile body 1 and pile crown 2 being fixedly connected,
Pile crown 2 includes the concrete body 21 and six blocks of steel plates 22 being fixedly connected, and concrete body 21 is cavity rotation body structure,
And bar-mat reinforcement is provided with it, for increasing the intensity of pile crown 2, six blocks of steel plates 22 are uniformly distributed along concrete body 21 is circumferential,
The length direction of steel plate 22 is parallel to the axis direction of concrete body 21, and the bottom of steel plate 22 is gathering type structure, and it is specially：
The bottom surface of steel plate 22 tilts down on the direction of the axis of concrete body 21, wherein, angle of inclination is 45 °, in piling
During, this inclined plane gradually to increase the extruding force of surrounding soil, and flexible fashion of extrusion was effectively reduced to week
The influence in collarette border.
In order to reduce pile side friction, steel plate 22 is isosceles ladder perpendicular to the cross sectional shape of the axis direction of concrete body 21
The distressed structure of shape, i.e., it is the upper following arc-shaped structure to be parallel to each other relative to the deformation part of isosceles trapezoid, wherein
The less arc-shaped edges of radius are close to the axis of concrete body 21.
It is provided with what is equidistantly arranged from top to bottom on parallel to the circumferential direction of concrete body 21 inside steel plate 22
Three run through through hole 22a, be generally aligned in the same plane on each steel plate 22 in through through hole 22a by through reinforcing bar 22b connections, being used for
Increase the intensity of steel plate 22, wherein a diameter of 10mm through through hole 22a.
The inner side that concrete body 21 is located at steel plate 22 is provided with convex edge 11, and convex edge relative to positioned at the outside of steel plate 22
11 bottoms are provided with the setting on the inclined-plane 12 tilted down on the inwall direction of steel plate 2, meter 11 and inclined-plane 12 so that steel plate
The concrete of inner side is higher than outside concrete thickness, can so play certain casting effect when rotated.
The thickness that concrete body 21 is located at the inner side of steel plate 22 is less than the thickness positioned at the outside of steel plate 22, the original so set
Because being that the part that concrete body 21 is located on the outside of steel plate is bigger relative to inner side stress during piling, by its thickness
What is set is larger, and it is broken can effectively to prevent that outside concrete is squeezed in piling.
A kind of operation principle of quick piling equipment in the present invention is as follows：
Multiple steel plates 22 are fixedly connected with concrete body 21, zigzag is formed in the end of steel-pipe pile by multiple steel plates 22
Structure, the hard geology such as the grains of sand layer for being mixed with cobble or laccolite can run into, or run into armored concrete existing for underground
During structural obstructions thing, above-mentioned barrier is broken through by the way of half reciprocating rotary, while effectively drop by following two structures
End resistance and pile side friction of the low above-mentioned broached-tooth design during piling：
1st, gather structure in the bottom design of steel plate 22, the method by reducing steel plate and bar contact area, add part
Pressure, it is effectively reduced end resistance；
2nd, by the section of steel plate 22 be arranged to it is upper it is following be circular arc isosceles trapezoid distressed structure so that the side of steel plate 22
When being bar contact, the crushing force local to barrier can be increased by the wedge angle that steel plate side is formed, while pass through circle
Globoidal structure characteristic, it can make again by separated barrier two sides respectively along the unresisted rotation of two arc surfaces, therefore effective drop
Low pile side friction.
Passing through above-mentioned structure so that steel-pipe pile can quickly work during downward piling and reciprocating rotary,
Effectively raise the speed of piling.
The foregoing description of the disclosed embodiments, professional and technical personnel in the field are enable to realize or using the present invention.
A variety of modifications to these embodiments will be apparent for those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, it is of the invention
The embodiments shown herein is not intended to be limited to, and is to fit to and principles disclosed herein and features of novelty phase one
The most wide scope caused.
