OPENING STRUCTURE OF UNDERGROUND STRUCTURE
To provide an opening structure in which a receiving frame 4 is easily raised and removed from the opening of an underground structure, and the surroundings of the receiving frame 4 are not destroyed during the removal.SOLUTION: In an opening structure of an underground structure, an anchor bolt 7 is passed through a bottom wall 9 of a receiving frame 4 to which a lid 5 is attached through a bottom wall insertion hole 14 provided in the bottom wall 9, a first nut 16 attached to the anchor bolt 7 is used to support a lower surface side of the bottom wall 9, and a second nut 17 is disposed on an upper surface side of the bottom wall 9. The bottom wall 9 is sandwiched between the first nut 16 and the second nut 17 so that the vertical position of the receiving frame 4 is fixed. The first nut 16 and the second nut 17 can be operated from a manhole space 6 inside the receiving frame 4.SELECTED DRAWING: Figure 3
【課題】地下構造物の開口部において、受け枠４の嵩上げや撤去が簡単であると共に、撤去に際して受け枠４の周囲を破壊することのない開口部構造の提供。【解決手段】地下構造物の開口部構造において、蓋５を装着する受け枠４の底壁９を、底壁９設けた底壁挿通孔１４にアンカーボルト７を貫通させ、アンカーボルト７に装着した第１ナット１６で前記底壁９の下面側を支持させ、第２ナット１７を前記底壁９の上面側に配置する。そして、第１ナット１６と第２ナット１７で前記底壁９を挟み付けて受け枠４の上下位置を固定してある。第１ナット１６と第２ナット１７は受け枠４の内側であるマンホール空間６から操作可能としてある。【選択図】図３
