Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a revetment structure constructed on a river or a coastline, in particular, a steel stone crate, and a multi-stage stacking type that forms a slope with a straight slope on the front. It belongs to the technical field of closed-wall protection structures.
[0002]
[Prior art]
In recent years, riverbanks and coastal revetments have come to use new revetment structures, such as basket mats filled with natural stones, from conventional concrete blocks, due to consideration for environmental friendliness.
[0003]
As shown in FIG. 6, the revetment structure using a car mat uses a car mat 10 in which a wire net is processed into a box shape having a width of 2 m to 4 m, a depth of 1 m to 1.5 m, and a height of about 0.5 m. A block is made by throwing stones into the stone. A revetment structure with a predetermined height is constructed by successively stacking the car mat blocks on the car mat block in the same manner. The revetment work using the car mat 10 is rapidly spreading due to its economical efficiency.
[0004]
[Problems to be solved by the invention]
The conventional revetment structure using a car mat has a problem that the constituent material of the car mat 10 is a rhombus wire mesh, and the strength and rigidity are not so strong, and the design and shape cannot be obtained at the time of construction. Therefore, in the actual revetment work, as illustrated in FIG. 7, a temporary material such as a single pipe 11 is passed in advance in the ridge line direction of the front upper corner portion so as to maintain the shape of the upper corner portion. A method of removing the pipe 11 is being carried out. Therefore, there is a problem that extra labor and temporary costs are required for handling the single pipe 11.
[0005]
In addition, there is a problem that it is difficult to obtain the shape accuracy because the car mat 10 is easily jammed and deformed by the introduction of the filling stone.
[0006]
Therefore, an object of the present invention is to solve the above-described conventional problems. Specifically, the steel frame body having a large shape holding function and easy to ensure the shape accuracy is used and the on-site assembly is performed. It is an easy structure and excellent in workability, and is intended to provide a staged steel stone-clad frame revetment structure that employs medium-filled stones and is environmentally friendly.
