Therefore, in recent years, various methods for reusing construction waste have been searched. For example, in the pack drain method for improving soft ground, it is introduced into a bag as a filler together with sand and inserted into a hole formed in a soft ground, To be used to improve the performance of the system.

At this time, in order for the aggregate using the construction waste to be used as the filler for the improvement of the soft ground, the aggregate in a state in which the foreign matter is removed should be crushed to a small size and then polished and processed to be uniformly charged in the ground.

However, the conventional crushing apparatus for reusing construction waste is a crusher for industrial, architectural and municipal waste (hereinafter referred to as Patent Document 1), a crushing and stripping apparatus for construction waste disposal of Registration No. 1549692 of Registration Patent No. 1871953, The construction waste collected as described in the method of producing recycled aggregate (hereinafter referred to as "Patent Document 2") is simply crushed by crushing into a crusher equipped with a crushing cutter, and the crushed aggregate is screened and discharged by the screen .

For this reason, the aggregates produced by the above Patent Documents 1 and 2 are put into the grinding machine to be used as a filler for improving the soft ground, so that further polishing work has to be carried out. As a result, the cost for producing the filler increases, Is becoming an increasing factor.

Therefore, it is required to develop an aggregate treatment device that can grind and polish so that it can be used as a filler for the improvement of soft ground when collecting and dismantling construction waste.

When the apparatus for treating the aggregate for the soft ground improvement using the construction waste according to the present invention as described above is used, as shown in FIG. 9, in a state where the inlet 34 of the drum body 31 is fixed to be positioned at the upper portion, The door 36 is operated to open the door 35 and a predetermined amount of aggregate is put into the drum body 31 through an input conveyor (not shown).

Then, a predetermined amount of water is injected into the drum body 31, then the opening / closing door 35 is closed, and the drum body 31 is rotated at a predetermined speed using the driving member 60.

As a result, both ends of the drum body 31 are raised and lowered by the inclination A of the first and second rotary shafts 32 and 33. The aggregate put into the drum body 31 is conveyed to the drum body 31, and is crushed to a predetermined size while being moved irregularly.

At this time, as shown in FIG. 10, the aggregate is pulled up to a predetermined height by the bucket 31B provided inside the drum main body 31, and then falls freely. At the same time, as shown in FIG. 11, The drum body 31 moves reciprocally within a predetermined range even in the horizontal direction so that the aggregates are more irregularly mixed and are crushed and polished as a whole quickly and effectively.

The aggregate, which has been crushed and polished by the aggregate treatment apparatus, is a filler for improving the soft ground having a predetermined size and a rounded surface. The filler 3 is sandwiched with the sand in the bag 2, Are inserted into the plurality of holes formed at predetermined intervals in the soft ground 1, respectively.

As described above, according to the present invention, both ends of the drum body are alternately raised and lowered by the inclination (eccentricity) of the first and second rotary shafts by rotating the drum body of the rotary drum, The aggregate charged into the drum body is entirely moved in the forward, backward, leftward and rightward directions in accordance with the repeated rotation of the drum body and the angular change, and is rapidly and effectively crushed and polished as a whole while being irregularly mixed. Thus, the construction waste aggregate is processed for the purpose of improving the soft ground do.
