BRIDGE INSPECTION PASSAGE
PROBLEM TO BE SOLVED: To provide a bridge inspection passage capable of sufficiently shortening duration to enforce traffic control for a bridge inspection vehicle; performing maintenance inspection of an entire lower side of a bridge; and being moved through simple operation.SOLUTION: A bridge inspection passage 10 comprises a first passage 21, a second passage 22 and a third passage 23 which overlap with each other. The first passage 21 and the overlapped second and third passages 22 and 23 can mutually slide in a bridge width direction. The third passage 23 and the overlapped first and second passages 21 and 22 can mutually slide in a bridge axial direction. The passages 21, 22 and 23 respectively have holding devices which can be freely positioned in a vertical and the bridge width directions and hold bridge girders. An electric cylinder 30 which extends and contracts in the bridge width direction is installed between the first passage 21 and the overlapped second and third passages 22 and 23. An electric cylinder 40 which extends and contracts in the bridge axial direction is installed between the third passage 23 and the overlapped first and second passages 21 and 22.
【課題】橋梁点検車による交通規制を行う時間を十分短縮することができ、橋梁の下側全体に対して保守点検を行えると共に、移動させる際の操作が容易である橋梁用点検通路を提供すること。【解決手段】橋梁用点検通路１０は、重なり合う第１通路２１と第２通路２２と第３通路２３とを有する。第１通路２１と、重なり合う第２通路２２及び第３通路２３とは、互いに橋幅方向にスライド可能であり、第３通路２３と、重なり合う第１通路２１及び第２通路２２とは、互いに橋軸方向にスライド可能である。各通路２１，２２，２３には、上下方向及び橋幅方向に位置調節可能で橋桁を把持可能な把持装置が設けられている。第１通路２１と、重なり合う第２通路２２及び第３通路２３との間に、橋幅方向に伸縮する電動シリンダ３０が取付けられ、第３通路２３と、重なり合う第１通路２１及び第２通路２２との間に、橋軸方向に伸縮する電動シリンダ４０が取付けられている。【選択図】 図３
