Abstract

(57) [Summary] [Purpose] A stone block is filled inside to form a frame for forming a revetment. [Structure] A frame that forms a plurality of box-shaped cells 2 and is constructed so as to cover the slope of a river. Joint fittings 3 stand at the corners of each cell 2, and an elongated steel panel 4 is bolted between the joint fittings.
Each cell 2 is packed with cobblestones or split stones 8 without gaps.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a frame body which is constructed so as to cover a slope such as a river and which is filled with boulders or crushed stones to protect the slope.

[0002]

[Prior art]

 Conventionally, there was a revetment method in which stone blocks were packed in iron wire knitting baskets called Futon cages and the stone blocks were lined up on the slope without any gaps. According to this method, reeds and willows grow in the crevices, and the crevices also serve as a hiding place for fish, allowing nature to remain.

However, although this futon basket is usually carried into the site after assembly, it is heavy and bulky, so that transportation costs are high and installation is not easy. In addition, there is a drawback that when a stone is thrown in, it is easily deformed. Furthermore, the mesh of the futon basket is usually about 100 to 130 mm, but the stone to be packed inside should be larger than that because it does not spill out from the mesh.

[0004]

[Problems to be solved by the device]

 The object of the present invention is to provide a frame body which replaces the futon basket having such drawbacks.

[0005]

[Means for Solving the Problems]

 The revetment construction frame of this invention is a frame body that forms a plurality of box-shaped cells for packing stone blocks. Fittings stand at the corners of each cell, and an elongated steel panel with a corrugated cross section is supported between these fittings.

[0006]

【Example】

 As shown in the figure, the revetment construction frame 1 of the present invention is a frame body in which a plurality of box-shaped cells 2 are formed, and is constructed so as to cover the slope of the river. Each cell has a size of 2 m × 1 m and a depth of about 25 to 45 cm.

A joint metal fitting 3 stands at a corner of each cell 2, and an elongated steel panel 4 is bolted between the joint metal fittings. The steel panels 4 are arranged in two rows, the upper and lower panels, and there is a 5 cm gap 5 between the upper and lower panels so that fish and the like can enter and leave. Of course, the steel panel itself has the water passage hole 6 on the entire surface.

Although the steel panel 4 has a thickness of 1.6 mm, it has a corrugated cross section for strength. The panel 4 is galvanized to prevent corrosion (the same is true of the fitting 3). The joint fitting 3 has a cross-shaped cross section (T-shaped or L-shaped depending on the location) and has bolt holes 7 on each side.

Each cell 2 is packed with cobblestones or split stones 8 without any gaps. If necessary, a wire net 9 is put on the stone block 8 so as not to be washed away, and the stone block 8 is fixed to the frame 1. Further, the lower side of the frame 1 may be covered with a wire mesh (not shown). A mat (not shown) may be laid under the frame 1 so that the soil will not be washed away.

[0010]

[Effect of device]

 The seawall construction frame of this invention is one in which steel panels are laid vertically and horizontally using joint fittings and stone blocks are packed inside.Since it can be easily assembled on site, the transportation cost is low, Since each member is lightweight, the work is easy. In addition, since it is a panel structure rather than braided iron wire, it has high strength and does not deform during stone filling. However, since it is not a net structure, it can be used even with relatively small stones.
