EMBANKMENT STRUCTURE, CONSTRUCTION METHOD FOR THE EMBANKMENT STRUCTURE AND WALL PART COMPONENT OF THE EMBANKMENT STRUCTURE

PROBLEM TO BE SOLVED: To provide an embankment structure of high workability and stability.SOLUTION: An embankment structure includes a banking 200 having alternately laminated three-dimentional grid-form cell layers 210 and banking layers 220, and a wall part 300 erected along the banking 200. The three-dimensional grid-form cell layer 210 includes a three-dimensional grid-form cell 100 having a plurality of cell structures 101 arranged in a grid form, and a filling material 102 filled in the cell structure 101. The three-dimensional grid-form cell 100 has a plurality of first belt-like bodies 10 arranged in parallel to each other and placed in a first horizontal direction that deviates away from the wall part 300, and a plurality of second belt-like bodies 20 arranged in parallel to each other and intersects with the first belt-like bodies 10, for forming the cell structure 101 along with the first belt-like bodies 10. The wall part 300 is provided with a protrusion (an engaged part 310, for example) that protrudes toward the banking 200, and the protrusion and the three-dimensional grid-form cell layer 210 are interconnected. 【課題】施工性および安定性が良好な盛土構造を提供する。【解決手段】盛土構造は、交互に積層された格子状立体セル層２１０と盛土層２２０を含む盛土２００と、盛土２００に沿って立設された壁部３００を備える。格子状立体セル層２１０は、格子状に配置された複数のセル構造体１０１を有する格子状立体セル１００と、セル構造体１０１に充填された中詰材１０２を備える。格子状立体セル１００は、互いに並列に配置され壁部３００から遠ざかる第１の水平方向に延在している複数の第１帯状体１０と、互いに並列に配置されて第１帯状体１０に対して交差し、第１帯状体１０とともにセル構造体１０１を構成している複数の第２帯状体２０を有する。壁部３００には、盛土２００側に突出した突出部（例えば係止部３１０）が設けられ、突出部と格子状立体セル層２１０とが相互に連結されている。【選択図】図１
