As a structure for this, the main body 10 of the double organ machine 1 is fixed to the front body 11 and the rear wall 12 in an integrated state by the left and right fixing plate bodies 13a and 13b.

The left and right wall bodies 14 and 15 of the main body 10 are attached to the rear body 12 in a state capable of moving left and right, and the inside of the left and right wall bodies 14 and 15. The plate bodies 14a and 15a are assembled to the left and right fixing plate bodies 13a and 13b as bolts or connected to the left and right sides of the front wall body 911 by auxiliary cover plate bodies 16a and 16b.

In addition, the rear part of each of the two organ drive units (2a) (2b), which are mounted on both sides of the main body (10) in the left and right sides, is detachably attached to the rear wall (12) as a bolt. The left and right walls 14 and 15 are assembled to the rear wall 12, and one side of the organ drive unit is assembled to the left and right walls 14 and 15 as bolts.

As described above, the rear wall 12, which allows movement control of the organ drive units 2a and 2b and the left and right walls 14 and 15, has two rows of bolt holes 12a at upper, middle, and lower sides. Many of them are formed in close proximity.

In addition, when the distance S between the organ drive units 2a and 2b is assembled at the minimum distance S1, the left and right walls 14 and 15 are each inner plate body 14a and 15a. Is assembled to the left and right fixing plate bodies 13a and 13b, but the interaxial distance S of the organ drive unit is out of the minimized state, so that the inner plate bodies 14a and 15a are left and right fixing plate bodies 13a and 13b. If the distance between the () and the maximum shaft distance (Sn) is adjusted to the auxiliary cover plate (16a, 16b) using the left and right walls 14, 15 and the front wall (11) to connect and assemble. To make it possible.

To this end, the upper and lower portions of the front wall 11 are arranged in a horizontal row a plurality of bolt holes (11a) in two rows.

The suspension pulley 4 is attached to the upper end of the main body 10 of the double organ machine 1, that is, the bracket 93 mounted on the upper left and right fixing plates 13a and 13b. (4) is to be suspended by the cable drawn from the upper end of the leader 101 so that the elevating operation, and the rear wall 12 to slide the guide rod (not shown) of the leader 101 to be slidable Three pairs of guides 5a, 5b and 5c are mounted on the upper, middle and lower parts.

On the other hand, the two organ drive units (2a) (2b) mounted in the interior of the main body 10 can be seen in the drawings of Utility Model Registration Application Nos. 94-16885 and Design Registration No. 171131 filed with the present cause. Bolt assembly holes are formed at the rear and one side of the body, and these bolt assembly holes allow the OGA drive unit to be assembled as a bolt to the rear wall 12 and the left and right walls 14 and 15.

Referring to the operation of the present invention configured as described above are as follows.

The two organ rods 102 are assembled in a multi-stage downward direction to the female joints 21a and 21b, which are output parts of the two drive units 2a and 2b mounted on the main body 10 of the double organ machine 1. After the excavation work is performed, when the excavation work is performed with the interaxial distance S of the two oga rods 102 as the minimum interaxial distance S1, as shown in FIGS. 2 and 3. The inner plate bodies 14a and 15a of the left and right wall bodies 14 and 15 are brought into contact with the left and right fixing plate bodies 13a and 13b, and then the inner plate bodies 14a and 15a and the left and right sides are moved. When the fixed plate bodies 13a and 13b are assembled as bolts and the left and right walls 14 and 15 are assembled as bolts on the rear wall 12, the left and right walls 14 and 15 The two organ drive units (2a) (2b) assembled are moved and fixed in close proximity to each other. At this time, the left and right covers 14b and 15b are in contact with both ends of the front wall 911, so that the auxiliary cover units 16a and 16b are not used.

When the two organo drive units 2a and 2b as described above are in close proximity to each other, the interaxial distance S between the female joints 21a and 21b and the two organo rods 102 is the minimum interaxial distance S1. In this way, when two orga rods 102 have a minimum shaft distance (S1) when the excavation work proceeds to the excavation radius and the total excavation width is to excavate the smallest excavation hole.

When the excavation hole is to be excavated with the excavation radius and excavation width larger than the minimum interax distance using the double organ machine 1 for excavating the excavation hole with the minimum interaxial distance S1, two organ drive units 2a. (2b) should be moved to the left and right directions to increase the interaxial distance (S), and adjusting the action of widening the interaxial distance to the maximum interaxial distance (Sn) as shown in FIGS. 4 and 5 As an example, the bolts previously assembled to the left and right fixing plates 13a and 13b and the rear wall 12 are removed, and then two organ drive units 2a and 2b as well as the left and right walls. ) Can be moved to the left and right sides, and accordingly, the organo drive units 2a and 2b are opposite to each other using a crane or the like, that is, the organo drive unit 2a on the left side of the drawing moves to the left. Move it, Oga Dry on the right side of the drawing. After moving the unit 2b to the right side, the left and right wall bodies 14 and 15 are assembled as bolts on both ends of the bolt hole 12a formed in two rows at the upper, middle and lower ends of the rear wall 12. In this case, each of the two organ drive units 2a and 2b can maximize the interaxial distance S in the region of the rear wall 12, and in this state, the left and right walls 14 and 15 are provided. Since the inner plate body 14a, 14b of the state is separated from the left and right fixing plate body 13a, 13b, the stability of the assembly state of the OGA drive unit may be insufficient, but in this case the auxiliary cover unit (16a) By using (16b), the organo drive unit can be assembled in a stable state.

That is, the sub cover plates 16a and 16b are formed at both ends of the bolt hole 11 formed horizontally in the upper and lower portions of the front wall 11, and the front and left sides of the left and right walls 14 and 15, respectively. Since the left and right walls 14 and 15 are assembled as bolts to the left and right covers 15a and 15b formed in the upper and lower covers 15a and 15b, the organo rod shaft distance S in such a state is the maximum interaxial distance ( Sn).

And the organo drive unit (2a) (2b) is mounted inside the main body 10, since its one side is always assembled to the left and right side wall (14, 15) to adjust the movement distance between the shaft (S) of the organo rod In this case, the left and right walls 14 and 15 can also be moved together as a means for moving the Oga drive units 2a and 2b by a crane, and the rear wall ( 12) means for assembling the left and right wall bodies 14 and 15 by selecting a plurality of bolt holes 12a horizontally arranged in two rows on the upper, middle and lower sides, and the upper and lower parts of the front wall 11; By selecting a plurality of bolt holes (11a) formed horizontally in two rows on the end of the auxiliary cover plate body (16a, 16b) as a means for assembling one end side of the bolt drive unit (2a) 2b to the radius and width of the excavation hole It can be selectively adjusted to fit.

On the other hand, as in the above embodiment, the two orga rods 102, in which the axial distance S is adjusted, are rotated in the same direction by two organ drive units 2a and 2b that are driven separately, respectively. Efficiency can be imparted to the stirring action of the excavated soil and the cement pool supplied to the strata.

That is, when the organo rod is rotated in different directions as shown in FIG. 7 as in the prior art, the agitation effect may be deteriorated since the soil and cement paste are stirred while moving in the same direction in the region where the stirring blades overlap each other. However, when the Oga rod rotates in the opposite direction as in the present invention, the soil and cement paste in the region where the stirring blades overlap are mixed with each other in the opposite direction. Thus, the stirring blade rotating in the opposite direction is stirred. As the operation is performed more efficiently, the ground improvement or in-situ file can be constructed according to the set strength.

According to the present invention as described above, the bolts arranged horizontally in two rows on the upper, middle, and lower side of the rear wall in a state where one side of each of the two right drive units mounted on the main body of the double organ machine is fixed to the left and right walls. As a means of selectively moving and fixing the ball, the distance between the shafts of the orga drive units can be selectively adjusted, so that one double orga machine can show the function of several ab orga machines, and two orga drive units can be individually The soil can be rotated in the opposite direction by stirring the soil and cement paste excavated in the area where the stirring blades that perform the rotational operation overlap with each other while maintaining the set inter-axis distance during ground improvement work or pile pile construction. And the cement paste more evenly to stir while rotating in the same direction It is a practical design that can obtain the effect of being agitated and can impart strength by design to the in-situ pile.
