Description

  The present invention relates to a concrete processing apparatus and a concrete processing method for processing concrete.

  In the concrete pump car after the concrete is placed, surplus concrete at the time of construction remains (so-called residual concrete). For this reason, at the end of the work, the concrete inlet and piping of the concrete pump truck are washed, the washing water containing the concrete at that time is received in the tray, and the concrete and clean water are separated.

  In the subsequent treatment, the water is manually drained by a worker, discharged to a predetermined outlet, neutralized, and then drained. On the other hand, the remaining components are solidified, and then manually crushed by hand to be disposed of. Patent Document 1 describes that the concrete is divided into small pieces by the air mat by pouring the remaining capacitor into the air mat provided with unevenness.

JP 2000-192657 A

  In performing such remaining control processing, the labor of the worker is tremendous. Although the air mat of Patent Document 1 reduces the work of crushing concrete, it still requires a great amount of labor to transport and discard the concrete after it is crushed. For example, the location where the remaining control processing is performed changes in the site depending on the placement position of the concrete, and it is a difficult task to transport the concrete from each location to the industrial waste disposal site.

  The present invention has been made in view of the above problems, and an object thereof is to provide a concrete processing apparatus and a concrete processing method capable of saving the processing of concrete.

  A first invention for solving the above-described problems includes a tray main body for storing concrete, a partition for partitioning the inside of the tray main body, and a fork insertion for inserting a fork of a forklift provided in the tray main body. And a concrete processing apparatus.

  In the present invention, by pouring the concrete into the tray body, the concrete is naturally divided into small pieces by the partition, and the concrete crushing work can be reduced. Moreover, the fork of the forklift can be inserted into the fork insertion section provided in the tray body, the tray body can be lifted and transported to the industrial waste disposal site, and the concrete can be discarded simply by inverting the tray body. Processing can be saved.

The fork insertion portion preferably has a space surrounded by a cylinder.
In the present invention, in a state where the fork of the full rotation forklift is inserted into the fork insertion portion of the tray main body, the fork can be rotated in the vertical plane to invert the tray main body, and the concrete can be dropped and discarded. As described above, when the fork insertion portion is a space surrounded by a cylindrical shape on the top, bottom, left, and right, the tray body does not come off the fork during the rotation.

It is desirable that a drain hole is provided on a side surface of the tray body.
Thereby, a pump and a hose can be connected to the drain hole to automatically discharge the clean water, thereby saving work.

Preferably, the partition is provided in the tray body, and an inner surface of a space defined by the partition has an inclined surface that is inclined so that the space is narrowed toward a bottom surface of the tray body.
This makes it easier to drop the concrete when the tray body is inverted.

Preferably, the concrete processing apparatus further includes a lid provided on the tray body, and the partition is provided on a lid body of the lid.
In this case, the concrete can be discarded from the tray body after the lid is lifted and the partition is removed. Since there is no adhesion between the partition and the concrete, the concrete is easily dropped and discarded from the tray body. Moreover, by shaking the lid when the concrete has solidified to some extent, the partition and the concrete adhere to each other, and the lid can be easily removed from the tray body.

Moreover, it is preferable that the inner surface of the space defined by the partition has an inclined surface that is inclined so that the space is narrowed toward the lid.
This makes it easier to lift the lid and remove it from the tray body.

The concrete processing apparatus further includes an outer tub that accommodates the tray body, and a frame that is detachably attached to an upper portion of the tray body, and the frame includes a fork insertion portion for inserting a fork of a forklift. It is also desirable to have
Since the concrete processing apparatus having such a configuration can store the above-mentioned clean water in the outer tub, the concrete processing apparatus has a configuration suitable for performing a large-capacity residual container processing. Moreover, in this concrete processing apparatus, the fork of the forklift can be inserted into the fork insertion portion of the frame, and the frame and the tray main body can be lifted and removed from the outer tank by the forklift. Then, by removing the frame from the tray body, the tray body can be transported and the concrete can be discarded in the same manner as described above.

[First Embodiment]
(1. Tray 1)
FIG. 1 is a view showing a tray 1 according to a first embodiment of a concrete processing apparatus of the present invention. The tray 1 according to the present embodiment is used in the above-described remaining-con processing, and saves the work. As shown in FIG. 1, the tray main body 10, the vertical plate 11, the inclined plate 12, and the fork insertion portion 13 are provided. Have.

  2A is a view of the tray main body 10 as viewed from above. FIGS. 2B and 2C are vertical cross sections of the tray 1 taken along lines aa and bb in FIG. 1, respectively. FIG.

  The tray main body 10 accommodates concrete. The tray body 10 is a box having an opening at the top, and in this embodiment, the flat surface is rectangular, but the present invention is not limited to this.

  A drain hole 101 is provided on the side surface of the tray body 10. The drain hole 101 is for draining clean water, which will be described later, and automatically drains clean water by connecting a pump and a hose to the drain hole 101 and sucking clean water, and draining work. Can be reduced.

  The inside of the tray body 10 is partitioned by a partition. The partition is composed of a vertical plate 11 and an inclined plate 12.

  The vertical plate 11 is a plate-like member provided in the vertical direction perpendicular to the bottom surface of the tray main body 10 and partitions the inside of the tray main body 10 in a lattice shape. A through hole 111 is provided in the upper part of the vertical plate 11. This through-hole 111 is for circulating the below-mentioned clean water.

  The inclined plate 12 is a plate-like member provided inside a lattice constituted by the vertical plate 11 or a lattice constituted by the vertical plate 11 and the side surface of the tray body 10.

  The inclined plate 12 is attached to the side surface of the vertical plate 11 or the tray main body 10 at its upper end, and is inclined with respect to the vertical direction so as to move away from the side surface of the vertical plate 11 or the tray main body 10 as it goes to the bottom surface of the tray main body 10. The lower end is attached to the bottom surface of the tray body 10.

  With the inclined plate 12, the inner surface of the space S partitioned by the partition has an inclined surface T that is inclined in a tapered shape so that the space S is narrowed toward the bottom surface of the tray body 10.

  Note that the upper end of the inclined plate 12 does not interfere with the flow of clean water through the through hole 111 of the vertical plate 11 and the drain hole 101 of the tray main body 10, and below the holes, the vertical plate 11 or the tray main body 10. Mounted on the side of the.

  The fork insertion portion 13 is for inserting a fork (claw) of a forklift, and is provided along the bottom surface of the tray body 10. The fork insertion portion 13 is formed by attaching both end portions 131 of a channel material having a C-shaped cross section to the bottom surface of the tray body 10, for example. Thereby, the fork insertion part 13 comes to have a space surrounded in a cylindrical shape on the top, bottom, left and right.

(2. Concrete processing method)
Next, the concrete processing method using the tray 1 of this embodiment is demonstrated. In the present embodiment, the concrete to be treated is concrete (remaining concrete) contained in the washing water after washing the concrete inlet and piping of the concrete pump truck, and this washing water is first poured into the tray body 10. Although not particularly illustrated, a cap that can be opened and closed is attached to the drain hole 101 of the tray body 10 in a closed state, and a drain hose is connected to the cap.

  When a certain amount of time elapses, the concrete and clean water are separated in the tray body 10, and the concrete 50 is precipitated as shown in FIG. The concrete 50 is solidified over time, and is naturally divided into small pieces by a partition (mainly the inclined plate 12).

  About the clean water, when the concrete 50 is solidified to some extent, the cap is opened and discharged from the drain hole 101. A pump is used to discharge the clean water. The discharged clean water is collected in a neutralization tank, neutralized, and then returned to sewage.

  After the concrete 50 is solidified, the fork 201 of the full rotation forklift 200 is inserted into the fork insertion portion 13 of the tray 1 as shown by the arrow A in FIG. 4A, and the tray 1 is lifted up as shown in FIG. 4B. And transport it to the industrial waste disposal site.

  The full-rotation forklift 200 is provided with an L-shaped fork 201 that can be moved up and down like a normal forklift, and the fork 201 is rotated 360 ° in a vertical plane by a rotating part 202 to which a vertical part of the fork 201 is attached. It is possible (see arrow B). By rotating the fork 201 by 180 ° in the vertical plane, the fork 201 is turned upside down as shown by a dotted line.

  After transporting the tray 1 to the industrial waste disposal site where the container 300 is located as shown in FIG. 5 (a), the fork 201 is raised, and the fork 201 is placed in the vertical plane above the container 300 as shown in FIG. 5 (b). Rotate 180 °. Then, the tray main body 10 is turned upside down, and the concrete 50 inside falls into the container 300. Note that it is also possible to carry only the tray 1 by a normal forklift (the fork 201 does not rotate).

  In this embodiment, since the partition of the tray 1 has the inclined surface T by the inclined plate 12, the concrete 50 can be easily dropped. That is, as shown in FIG. 6A, when the tray 50 is inverted and the concrete 50 is dropped, the concrete 50 is immediately separated from the inclined plate 12 and can be attached. On the other hand, when there is no inclined plate 12 as shown in FIG. 6B, when the concrete 50 is dropped, friction is continuously generated between the vertical plate 11 and the side surface of the tray body 10, and the concrete 50 is dropped. It becomes difficult.

  According to this embodiment described above, the concrete 50 is naturally divided into small pieces by the partition by pouring the cleaning water including the concrete 50 into the tray body 10, and the crushing work of the concrete 50 can be reduced. Moreover, the fork of the forklift can be inserted into the fork insertion portion 13 and the tray body 10 can be lifted and transported to the industrial waste disposal site. The concrete 50 can be discarded simply by turning the tray body 10 upside down. It can save labor. Furthermore, the tray 1 of this embodiment has an advantage that it can be easily manufactured with a relatively simple configuration.

  In the present embodiment, a full-rotation forklift 200 is used as the forklift, and the fork 201 is rotated in a vertical plane with the fork 201 inserted into the fork insertion portion 13 of the tray body 10, and the tray body 10 is inverted. The concrete 50 can be dropped into the container 300 and discarded. As described above, the fork insertion portion 13 has a space surrounded in a cylindrical shape on the top, bottom, left and right, so that the tray body 10 does not come off the fork 201 during the above rotation.

  Moreover, in this embodiment, a pump and a hose are connected to the drain hole 101 provided on the side surface of the tray main body 10 to suck in the clean water, and the clean water can be automatically discharged, thereby reducing the work.

  Moreover, in this embodiment, since the partition has the inclined surface T by the inclined plate 12, the concrete 50 is easily dropped when the tray body 10 is inverted as described above. In addition, the peeling agent may be apply | coated to the side surface of the inclination board 12, the vertical board 11, and the tray main body 10, and it may make the concrete 50 fall more easily.

  However, the present invention is not limited to this. For example, the shape and material of each part of the tray 1 are not particularly limited, and it is only necessary to have at least a partition that partitions the tray main body and the inside of the tray main body and a portion that corresponds to the fork insertion portion.

  Moreover, although this embodiment demonstrated the example which processes the concrete contained in the wash water after wash | cleaning the concrete inlet and piping of a concrete pump car, the concrete of a process target is not restricted to this, The concrete of this embodiment The tray 1 can also be applied to other remaining content processing. For example, it may be used for processing concrete contained in the washing water after washing the chute of an agitator vehicle that carries concrete into the field. In this case, the washing water is poured into the tray body 10. Alternatively, surplus concrete remaining in the concrete pump truck after the concrete is placed may be poured directly into the tray body 10. In this case, the above-described treatment of clean water is not necessary. Furthermore, the tray 1 according to the present embodiment is not limited to the remaining residual processing, and can be applied to general processing of unnecessary concrete.
