First, the structure removing and conveying vehicle is suspended to perform the removing work. Get down to the floor. And FIG.
As shown in, a concrete wall, which is an underground buried object, is cut into a block shape having a weight of 15 tons or less with a wire saw, and the latch plate 21 is attached to the side surface of the removed object 20 obtained by cutting by a chemical anchor construction. At the same time as mounting, the structure-removing transport vehicle is made to approach in a running posture to a position where the tip of the removed-object loading body 12a substantially contacts the lower side surface of the concrete wall. In addition,
The concrete wall may be cut with a normal concrete cutter.

As shown in FIG. 4, the rod of the first stage lift cylinder is extended or the rod of the second stage lift cylinder is extended until the upper surface of the removed object stack 12a of the lifter 12 is located slightly below the cut surface of the removed object 20. The removal object loading body 12a is raised by the reduction of the
The rod of the pulling cylinder 15 that has risen along with it is extended, and the hooking member 15 a provided at the tip of the rod is hooked on the latch plate 21. When the cut surface of the concrete wall is inclined, the rod of the attachment operating cylinder 5 is expanded / contracted so that the angle of the removed material stack 12a is adjusted to the tilt angle of the cut surface of the concrete wall.

When the rod of the pulling cylinder 15 is contracted, the removed material 20 is attracted toward the work attachment 10 as shown in FIG.
While moving to the top of a, the side surface of the removed article stack 12 a on the side of the work attachment 10 abuts on the front surface of the swing frame 11. As a result, the removed material 20 is firmly fixed to the work attachment 10, and even if the construction removal transportation vehicle sways during traveling due to the uneven excavation roadbed, the removed material 20 is removed from the lifter 12 of the work attachment 10. There is no fall.

When the side surface on the side of the work attachment 10 comes into contact with the front surface of the swing frame 11 in this way, as shown in FIG. 6, the removed object loading body 12a is further raised, and as shown in FIG. The structure-removed transport vehicle is moved away from the concrete wall, that is, the structure-removed transport vehicle is moved backward to lower the structure-removal stack 12a so that the structure-removal vehicle is moved to the running posture.

Then, as shown in FIG. 8, the structure removing and conveying vehicle is moved to the intended place for removing the removed object.
In that place, a pair of pedestals 23 made of, for example, a board or the like is arranged in advance at an interval wider than the width of the removed material stack 12a. Therefore, the removed object loading body 12a is attached to the pair of pedestals 2
When the removed object 20 is supported by the pair of pedestals, the structure removed transportation vehicle is moved backward. In this way, the removed article 20 unloaded on the cradle 23 is
Using the latch plate 21, it is suspended by a crane or the like, and is loaded on, for example, a trailer. Then, the removed product 20 from which the latch plate 21 is removed for reuse is transported to a predetermined place by the trailer. In addition, the rod of the attachment actuation cylinder 5 is extended according to the inclination of the unloading roadbed, and the angle of the removed material stack 12a is changed.

Hereinafter, the same work is repeated until the removal of all the underground buried objects is completed. However, according to the structure removing transport vehicle according to the first embodiment, the removal of the underground buried objects according to the conventional example is performed. There is no need to jack up and remove the underground debris on multiple floors by a manual operator such as a heavy-duty crane as in the case of work, and load the debris by expanding and contracting the rod of the 1-stage lift cylinder or 2-stage lift cylinder. Body 12a
The lifting / lowering operation of 1 and the expansion / contraction operation of the rod of the pulling cylinder 15 allow the removed object 20 to be placed on the removed object loading body 12a without ground cutting.

Then, the removed article 20 placed on the removed article stack 12a is firmly fixed to the work attachment 10 by the pulling force of the pulling cylinder 15 and the removed article 20 is removed.
Since it can be transported and removed without dropping from the lifter 12, it is possible to improve the removal work efficiency of underground buried objects, improve safety, and reduce removal cost.

Further, according to the structure removing and conveying vehicle according to the first embodiment, since it is a crawler traveling type rather than a tire traveling type like a forklift, the unloading roadbed for conveying the removed matter has many irregularities. Even if the roadbed is used, there is an extremely excellent effect that the removed article 20 can be carried out while traveling stably.

By the way, depending on the situation of the removal work site, the structure removal transport vehicle may not be able to be oriented at right angles to the concrete wall. In that case, FIG. 9 of the work situation explanatory diagram
As shown in, the tip angle of the removed material loading body 12a is set to an angle corresponding to the orientation of the concrete wall and the structure removal transport vehicle, and the removed material 20 is drawn by pulling the removed material 20 according to the same work procedure as above. Just put it on top.

When the structure removing conveyance vehicle cannot be brought close to the position of the removed object 20, one end of the wire rope 22 is tied to the latch plate 21 as shown in FIG. The end of the pulling cylinder 15 is hooked on the hooking member 15a provided at the tip of the rod to retract the building removal vehicle to move the removal object 20. Next, the structure-removed transport vehicle is brought close to the removed product 20, and the removed product 20 is drawn by the same work procedure as above to remove the removed product loading body 12a.
Just put it on top.

In the above description, the case where the structure removing and conveying vehicle is applied to the removal work of the underground buried object is explained, but the structure removing and conveying vehicle can be applied to the removal of the concrete structure on the ground, and the crane is further used. Since it can be used for various works such as culvert transfer / installation in places where vehicles cannot enter, formwork transfer in joint mines, transfer of various equipment in tunnel construction, transfer of large panel formwork in revetment work, etc. The application of the structure removing and conveying vehicle according to the present invention is not limited to the application to the above underground buried removing method.
