Detailed description of the invention

For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Embodiment 1, referring to Fig. 1 and Fig. 2, the present embodiment is the double mixing pile machine of three axles of the every row of 2 row, and three drilling rods of every row and stirring-head are by being overlapped to form word order, and three drilling rods tops of the every row of 2 row are provided with headstock 5, are provided with drive motors in headstock.Motor output shaft connects a reducer, reducer jointed rod.Can control like this rotating speed of drilling rod, reach the rotating speed requirement needing, and can not damage motor.

First row drilling rod is from left to right followed successively by the first drilling rod 11, the second drilling rod 12,13, three drilling rod one words of the 3rd drilling rod and in a row arranges; Second row drilling rod is from left to right followed successively by the first drilling rod 21, the second drilling rod 22,23, three drilling rod one words of the 3rd drilling rod and in a row arranges.Further, described drilling rod is hollow drill pipe, and inside is provided with slip casting passage, and drilling rod front end is provided with gunniting hole.Can in drilling process, whitewash like this, or on while carrying drilling rod, whitewashing.

For each gang drill bar, the stirring vane of adjacent two drilling rods or blade be not on sustained height, and stirring vane 6 or blade 7 radical lengths are d, and the spacing of adjacent drill pipes is D, d > D/2.The agitation pile that this gang drill bar forms overlaps mutually.

Row's spacing of two gang drill bars is H, d > H/2, and 6 drilling rod rotations form the cement mixing method that 2 rows overlap mutually simultaneously.

Stirring vane or blade rotating diameter are 300-2000mm; The power of each motor is more than 20KW, more than the mouth spray diameter 5mm of shotcrete pipe.

This size can ensure to rotate freely between adjacent drill pipes, do not interfere, and pile is intensive.Formation of pile medium power is abundant, and pile-forming speed is effective soon.

Pile plan view is shown in Fig. 3 a or Fig. 3 b, once can arrange three agitation piles of every row by pile two, and every row's agitation pile overlaps mutually, also mutually overlaps between row and row.While constructing the second width stake, beat or overlap with the first width encapsulation.

Embodiment 2, referring to Fig. 4, increases the row's spacing H between two gang drill bars, d > H/2, and 6 drilling rod rotations form the cement mixing method that 2 rows do not overlap mutually simultaneously.Pile plan view is shown in Fig. 5 a, Fig. 5 b, once can arrange three agitation piles of every row by pile two, and every row's agitation pile mutually overlaps or overlaps and beat, but does not mutually overlap between row and row.All the other are with embodiment 1.
