Technical problem to be solved in the utility model is, the mixing pile machine of a pile of a kind of function that improves mixing pile machine mixing water earth and efficiency of construction is provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of mixing pile machine of a pile, comprise drilling rod, unit head, frame, slush pump, air compressor machine and be connected the drill bit of drilling rod bottom, the drilling rod of next-door neighbour's drill bit is the band blade drilling rod that has the multilayer stirring vane, is used for also being provided with in the drilling rod of transporting water mud spraying compressed-air actuated air inlet pipe.
Band blade drilling rod be not with blade drilling rod joint, the sliding support of the maintenance drilling rod verticality that can slide along drilling rod and frame is set; Be fixed on the frame in the frame lower setting, make the fixed support of the freely through maintenance drilling rod verticality of band blade drilling rod energy.
Described fixed support comprises the fixed bar that is fixed on the frame and is fixed on the freely through pilot of stirring vane energy that making of fixed bar top is with on the blade drilling rod that the two ends of pilot have the horn mouth shape.
Long 1.8 meters to 4 meters of described band blade drilling rod, the interlamellar spacing 30cm of stirring vane～40cm, 2 every layer.
Described stirring vane is positioned at 180 phase places of spending perpendicular to drilling rod between every layer of two stirring vane, the stirring vane between the adjacent two layers is positioned at the phase places of 90 degree.
Described stirring vane between layer by layer is by equidistantly arranging.
The beneficial effects of the utility model are: construction one spray one of agitation pile is stirred and can be finished, a pile, and work efficiency is more than 3 times of conventional mixing pile machine.Increase compressed air in the whipping process simultaneously, by compressed-air actuated effect, helping increases the uniformity that cement-soil stirs, and then further improves pile quality.
Description of drawings
Fig. 1 is existing mixing pile machine structural representation.
Fig. 2 is the mixing pile machine structural representation of a pile of the present utility model.
The specific embodiment
The mixing pile machine of a pile that the utility model is provided below in conjunction with the drawings and specific embodiments is elaborated:
As shown in Figure 2, the mixing pile machine of a pile of the present utility model, comprise drilling rod, unit head 8, frame 5, slush pump 9, air compressor machine 1 and be connected the drill bit 10 of drilling rod bottom, the drilling rod of next-door neighbour's drill bit 10 is the band blade drilling rod 4 that has multilayer stirring vane 11, is used for also being provided with in the drilling rod of transporting water mud spraying compressed-air actuated air inlet pipe 2.Band blade drilling rod 4 be not with blade drilling rod 12 joints, the sliding support 3 of the maintenance drilling rod verticality that can slide along drilling rod and frame 5 is set; Setting is fixed on the frame 5 in frame 5 bottoms, makes the fixed support of the freely through maintenance drilling rod verticality of band blade drilling rod 4 energy.
Described fixed support comprises the fixed bar 6 that is fixed on the frame 5 and is fixed on the freely through pilot 7 of stirring vane 11 energy that making of fixed bar 6 tops is with on the blade drilling rod 4 that the two ends of pilot 7 have the horn mouth shape.
1.8 meters to 4 meters of described band blade drilling rod 4 length, the interlamellar spacing 30cm of stirring vane 11～40cm, 2 every layer.Described stirring vane 11 is perpendicular to drilling rod, is positioned at the phase places of 180 degree between every layer of two stirring vane 11, and the stirring vane 11 between the adjacent two layers is positioned at the phase places of 90 degree.Stirring vane 11 described in the present embodiment between layer by layer is by equidistantly arranging.
