| description | To provide an assembly-type box-shaped manhole capable of structuring an ultra-large manhole using a precast box-shaped block and remarkably improved in bending bearing force and torsion bearing force at a joint part between a pair of split pieces formed by dividing the box-shaped block.SOLUTION: An assembly-type box-shaped manhole includes a box-shaped manhole section composed of plural box-shaped blocks being stacked up, in which the box-shaped blocks are formed by: using a pair of split pieces 25, 25 having an angular U shape in a plan view and mechanical joint means that interconnects joint parts of the split pieces 25, 25; forming an inward bending hole 26 and an outward bending hole 26 in the joint parts of the pair of split pieces 25, 25; disposing a pair of bending upholstery members 27, 27 along the pair of bending holes 26, 26; and fixing end parts of strained respective bending upholstery members 27 with anchorages 28.SELECTED DRAWING: Figure 7
【課題】ブレキャスト製の箱形ブロックを使用して超大型マンホールを構築できると共に、箱形ブロックを分割した一対の分割ピースの接合部の曲げ耐力とねじれに対する耐力が格段に向上する、組立式箱形マンホールを提供すること。【解決手段】複数の箱形ブロックを積み重ねて構成する箱形マンホール部を具備する組立式箱形マンホールであって、箱形ブロックを平面形状がコ字形を呈する一対の分割ピース２５，２５と、分割ピー２５，２５スの接合部間を連結する機械的連結手段とを使用し、一対の分割ピース２５，２５の接合部に内向きの曲がり孔２６と外向きの曲がり孔２６を形成し、一対の曲がり孔２６，２６に沿って一対の曲がり引張材２７，２７を配置し、緊張した各曲がり引張材２７の端部を定着具２８で固定する。【選択図】図７ |
