INSTALLATION METHOD OF PRESSURE PROOF WATER PROOF IRON COVER
To provide an installation method of a pressure proof water proof iron cover in which a height adjustment work is easy in installing a receiving frame in accordance with a road slope and which can secure high pressure proof water proof property.SOLUTION: An installation method of a pressure proof water proof iron cover fixes a cover body and a receiving frame 12 for an underground structure with a bolt. The installation method includes the steps of: installing the receiving frame 12 with a space 40 interposed between itself and an upper face of an underground structure 30 via a height adjuster 20; installing a formwork so as to cover the space 40 from an inner peripheral side and an outer peripheral side; and filling the space 40 with a mortar 70. The step of installing a formwork includes, after the step of filling, a step of installing a gap forming formwork 53 so as to form a gap portion 80 along the whole circumference of an inner peripheral edge of a lower face of the receiving frame 12, and further includes, after the step of filling, a step of filling the gap portion 80 with an elastic sealant 90.SELECTED DRAWING: Figure 2
【課題】道路勾配にあわせて受枠を設置する際に高さを調整する作業が容易で、かつ高い耐圧防水性を確保することのできる耐圧防水鉄蓋の設置方法を提供する。【解決手段】地下構造物用の蓋本体と受枠１２とをボルトで固定する耐圧防水鉄蓋の設置方法であって、高さ調整具２０を介して地下構造物３０の上面に対して空間４０を隔てて受枠１２を設置する工程と、空間４０を内周側および外周側から覆うように型枠を設置する工程と、空間４０にモルタル７０を充填する工程と、を含み、前記型枠を設置する工程は、前記充填する工程の後に受枠１２の下面の内周縁全周に沿って空隙部８０が形成されるように、空隙部形成用型枠５３を設置する工程を含み、前記充填する工程の後に、空隙部８０に弾性シーリング材９０を充填する工程をさらに含む。【選択図】図２
