DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding net cage structure, and is particularly suitably used for river and coastal revetment and road slope construction.

[0002]

2. Description of the Related Art Conventionally, car mats as shown in FIG. 9 have been used for revetment works on rivers, coasts, and the like, and slope works on roads. The car mat a is formed in a substantially box shape by a bottom net b, four side nets c, and a lid net d. Each net is formed in a substantially box shape with four sides surrounded by a frame line e and connecting portions connected by a coupling coil f. In addition, a reinforcing wire g is inserted into the inside as necessary to provide strength. Further, the bottom net b, the side net c, and the lid net d are formed by stitching column lines h formed in a continuous chevron as shown in FIG.

[0003] In this way, the car mat a is assembled in a factory and transported to a construction site. Then, stuffing is performed with the lid net d opened, the lid net d is closed, and the coupling coil f is closed.
Alternatively, the lid net d is fixed to the side net c with a clip. At the construction site, many such car mats a are placed adjacent to each other,
We decide to cover a large plane.

[0004]

However, the conventional car mat a shown in FIG. 9 is assembled in a box shape at a factory, but it takes much time to assemble, and the car mat a is adjacent to the car mat a. In this part, two side nets c are overlapped, and there is much waste. In addition, since the laying is carried to the construction site after being assembled at the factory, the outer volume is bulky, and only a small number of them can be carried. In addition, the cage mat a could not be easily moved at the time of laying, and the workability was poor. Furthermore, a large area was required for storage in a warehouse or the like. The present invention solves the inconveniences of the conventional car mats described above, and when not in use, can be easily folded and folded, so that a large amount of transport and movement can be easily performed and stored in a warehouse or the like without requiring a large area. An object of the present invention is to provide a folding net cage structure that can be efficiently laid, is easy to manufacture and assemble, has no waste in overlapping adjacent parts, and has a robust structure.
