MANHOLE BLOCK AND MANUFACTURING METHOD THEREOF
PROBLEM TO BE SOLVED: To provide a manhole block with a high uplift pressure resistance capable of preventing being broken due to uplift pressure.SOLUTION: The manhole block includes: a cylindrical block body 11 of a precast concrete, which has an opening at the top; plural anchor members 12 which are embedded in an upper area of the block body 11 for fixing a manhole receiving frame 3 at intervals in a circumferential direction; and a circular reinforcement member 31 which is embedded in an upper area of the block body 11 along the circumferential direction. The reinforcement member 31 is formed independently from the anchor member 12 being disposed at a certain distance from the anchor member 12 in a diameter direction crossing a breaking region A of the block body 11 due to the uplift pressure.
【課題】耐揚圧強度を高め、揚圧による破壊を防止することができるマンホールブロックを提供する。【解決手段】上端に開口を有するプレキャストコンクリート製の筒状のブロック本体１１と、ブロック本体１１の上部に周方向に間隔をあけて埋設され、マンホール受枠３を固定するためのアンカー部材１２と、ブロック本体１１の上部に周方向に沿って埋設された環状の補強部材３１と、を備えており、補強部材３１は、アンカー部材１２とは別体で構成され、当該アンカー部材１２と径方向に間隔をあけて配置されるとともに、揚圧によるブロック本体１１の破断領域Ａを横切って配置されている。【選択図】図３
