PREFABRICATED MANHOLE STRUCTURE AND CONSTRUCTION METHOD FOR THE SAME
To provide a new construction method for a prefabricated manhole which fundamentally reviews a conventional prefabricated manhole structure, and reduces the size.SOLUTION: A prefabricated manhole structure is composed of a plurality of concrete segments that are mutually connected. The prefabricated manhole structure includes a section 21 for lifting work having a bottom part 12, a wall part 13 and a top part 14, and a tunnel section 31. The section 21 for the lifting work includes a lid support cylinder part 49 for a hole for lifting. The tunnel section 31 is arranged between right and left sections 21 for lifting work. The height from the bottom part 12 and the top part 14 of the tunnel section 31 is lower than the height of the top part 14 of the section 21 for the lifting work, is lower than the height of the conventional top part 14 of (B), but a distance between the ground surface and the top part 14 of the tunnel section 31 is substantially equal to the conventional distance between the ground surface and the top plate 14 of (B).SELECTED DRAWING: Figure 1
【課題】従来のプレハブ式マンホール構造体を抜本的に見直し、そのダウンサイジングとこれに基づくプレハブマンホールの新たな施工方法の提供を図る。【解決手段】 互いに接続された複数のコンクリート製のセグメントによって構成されたプレハブ式マンホール構造体。底部12と壁部13と天部14とを有する昇降作業用区間21とトンネル区間31とを備える。昇降作業用区間21は昇降用ホール用の蓋支持筒部49を備える。トンネル区間31は左右の昇降作業用区間21の間に配置される。トンネル区間31の底部12から天部14までの高さは、昇降作業用区間21の天部14の高さよりも低く、(B)の従来の天部14の高さよりも低いが、地表からのトンネル区間31の天部14までの距離は、(B)の従来の地表から天部14までの距離と略等しい。【選択図】図1
