REINFORCEMENT METHOD AND REINFORCEMENT STRUCTURE OF RECTANGULAR MANHOLE
To perform sufficient reinforcement against stress received by a buried manhole, while reducing reinforcement operation and material cost.SOLUTION: A reinforcement method of a rectangular manhole of this invention comprises: providing a band-like reinforcement material 2 formed of reinforced fibers only on a lower floor slab 11 of a rectangular manhole 10; and fixing an upper part of a side wall 12 to an upper floor slab 13 of the rectangular manhole 10, and a lower part of the side wall 12 to the lower floor slab 11, respectively by a reinforcement member 3, at a center part of a longitudinal side in the side wall of the rectangular manhole 10. A reinforcement structure of a rectangular manhole of this invention comprises: the band-like reinforcement material 2 formed of the reinforced fibers provided only on the lower floor slab 11 of the rectangular manhole 10; and the reinforcement member 3 fixing the side wall 12 to upper floor slab 13 of the rectangular manhole 10, and the side wall 12 to the lower floor slab 11 respectively, at the center part of the longitudinal side in the side wall of the rectangular manhole 10.SELECTED DRAWING: Figure 1A
【課題】補強にかかる稼働および材料費の削減を図りつつ、埋設されたマンホールが受ける応力に対する十分な補強を施す。【解決手段】本発明に係る矩形マンホールの補強方法は、矩形マンホール１０の下床版１１にのみ、強化繊維製の帯状補強材２を設け、矩形マンホール１０の側壁長手側中央部において、側壁１２の上部と矩形マンホール１０の上床版１３、および、側壁１２の下部と下床版１１とをそれぞれ、補強部材３により固定する。また、本発明に係る矩形マンホールの補強構造は、矩形マンホール１０の下床版１１にのみ設けられた、強化繊維製の帯状補強材２と、矩形マンホール１０の側壁長手側中央部において、側壁１２と矩形マンホール１０の上床版１３、および、側壁１２と下床版１１とをそれぞれ固定する補強部材３と、を備える。【選択図】図１Ａ
