BOX CULVERT AND CONSTRUCTION METHOD THEREFOR
PROBLEM TO BE SOLVED: To provide a box culvert capable of having both high workability and economy although using a precast concrete block, and a construction method therefor.SOLUTION: A box culvert 1 which is sectioned in a rectangular shape wider in a width direction W than in a height direction H consists of: a top gate type member 10 which has side wall upper parts 12 on both sides and a top part 11 constituted in one body and made of precast concrete, a side part L type member 20 which has a side wall body part 21 and a floor slab side part 22 constituted in one body and made of precast concrete, and a floor slab center member 30 made of cast-in-place concrete, a height-directional joint part 3 of the top gate type member 10 being composed of a rigid connection structure F, and a width-directional joint part 2 being composed of a hinge joint structure P.SELECTED DRAWING: Figure 1
【課題】プレキャストコンクリートブロックを用いながら、より高い施工性と経済性とを両立できるボックスカルバート及びその構築方法を提供することを目的とする。【解決手段】高さ方向Ｈに対して幅方向Ｗが広い矩形断面のボックスカルバート１を、両側の側壁上部１２と頂部１１とが一体構成され、プレキャストコンクリートで構成した頂部門型部材１０と、側壁本体部２１と床版側方部２２とが一体構成され、プレキャストコンクリートで構成した側部Ｌ型部材２０と、現場打ちコンクリートで構成した床版中央部材３０とで構成し、頂部門型部材１０における高さ方向接合部３を剛結構造Ｆで構成するとともに、幅方向接合部２をヒンジ接合構造Ｐで構成した。【選択図】図１
