Lower end connects, and the jet of the high pressure nozzle is located at drill bit outward flange, and the jet is three groups and becomes T-type structure to arrange,
Wherein two groups jets are located in same level, another group of jet opening down.
Preferably, the width of the gap is 2～4cm.
Another technical scheme of the present invention, the stake end formed by high pressure base expanding and base expanding screw rod drilling equipment expand
Head, with enlarged footing body, the cylindrical pile body inwall of the enlarged footing body upper end has shallow-layer screw thread.
Compared to prior art, the device have the advantages that：
1st, on helical blade with gap, form air duct, less churning resistance, amount of being unearthed for former amount of being unearthed 10～
30%.Its structure is novel, pile quality is good, be difficult bit bouncing.
2nd, high pressure nozzle has three groups of jets or one group, and the stake end enlarged footing aperture formed by three groups of jets is more
Greatly, and amount of being unearthed is little, pile bearing capacity is high, and pile quality is good.
Description of the drawings
Fig. 1 is the structural representation of the present invention,
Fig. 2 is stake end enlarged footing structural representation of the present invention.
Specific embodiment
The present invention is described in detail with reference to the accompanying drawings and detailed description.
A kind of high pressure base expanding and base expanding screw rod drilling equipment, structure is as shown in figure 1, the drilling equipment has drilling rod 1, and is connected in
The drill bit 4 with discharging opening of 1 lower end of drilling rod, turns clockwise along 1 outer wall of the drilling rod and is provided with helical blade 2, described
Several gap 3 of spaced set on helical blade 2, and the height of helical blade 2 is 2～4cm.
In the present embodiment, the drilling equipment also has slurry casting machine 5 and high pressure nozzle 7, and 5 one end of the slurry casting machine connects
There is Grouting Pipe 6, the Grouting Pipe 6 is fixed on 1 madial wall of drilling rod, and the high pressure nozzle 7 is arranged at the inner side of 4 flank of drill bit,
And be connected with 6 lower end of the Grouting Pipe, the jet 71 of the high pressure nozzle 7 is located at 4 outward flange of drill bit, and the jet 71 is
Three groups and T-type structure is become to arrange, wherein two groups jets 71 are located in same level, the opening court of another group of jet 71
Under.
Wherein, the width of the gap 3 is 2～4cm.
The stake end enlarged footing formed by high pressure base expanding and base expanding screw rod drilling equipment, with enlarged footing body 8, the enlarged footing body
