REPAIR STRUCTURE FOR EXISTING MANHOLE
PROBLEM TO BE SOLVED: To provide a repair structure that prevents deviation and falling, for repairing an existing manhole without a measure implemented for preventing deviation.SOLUTION: A repair structure is for an existing manhole configured by piling up cylindrical constituent members. A groove is formed from an inner peripheral surface side of the piled constituent members (a straight wall piece 2, an oblique wall piece 3) on at least three locations that almost equally divide a circumference of the inner peripheral surface, across a connecting part 10 of the piled constituent members. A shear-proof member (a shear plate 11) is inserted into the groove for connecting the piled constituent members via the shear-proof member, such that the shear-proof member resists forces of different directions that are exerted on the piled constituent members and then cause deviation.SELECTED DRAWING: Figure 1
【課題】ずれ対策が講じられていない既設マンホールを補修してずれや倒れを防ぐ補修構造を提供する。【解決手段】筒状の構成部材を積み上げて構成した既設マンホールの補修構造であって、積み上げられた構成部材（直壁ピース２、斜壁ピース３）の内周面を略等分した少なくとも三か所に、積み上げられた構成部材の接続部１０を横断して内周面側から溝を形成し、溝に耐せん断部材（せん断プレート１１）を挿入して該耐せん断部材を介して積み上げられた構成部材を連続させ、積み上げられた構成部材に互いに異なる方向への力が作用してずれようとしたとき、該力に対し耐せん断部材によって対抗し得るように構成する。【選択図】図１
