LID-RECEIVING FRAME SET FOR UNDERGROUND STRUCTURE
To provide a lid-receiving frame set for underground structure which efficiently releases an inner pressure by securing a discharge amount of a fluid, and can suppress scattering of a lid for underground structure.SOLUTION: A lid-receiving frame set for underground structure includes a receiving frame 3 buried in a state in which an upper end face 32 is exposed to a ground G, and a lid 2 for underground structure having a side face 22 provided with a fitting part fit to an inner peripheral surface 31 of the receiving frame 3, in which the side face 22 of the lid 2 for underground structure is provided with an inner pressure release port 7a that has an upper part that is blocked and is opened toward the inner peripheral surface 31 in a state in which the fitting part is fit to the inner peripheral surface 31 of the receiving frame 3, and the lid 2 for underground structure has a release flow channel 7b which has a lower part and an inner part that are opened and is connected to the inner pressure release port 7a.SELECTED DRAWING: Figure 5
【課題】流体の排出量を確保することによって内圧を効率的に解放し、地下構造物用蓋の飛散を抑えることができる地下構造物用蓋受枠セットを提供する。【解決手段】上端面３２が地上Ｇに露出した状態で埋設される受枠３と、受枠３の内周面３１に嵌合する嵌合部が設けられた側面２２を有する地下構造物用蓋２とを備え、地下構造物用蓋２の側面２２は、上部が塞がれ、嵌合部が受枠３の内周面３１に嵌合した状態では内周面３１に向かって開口する内圧解放口７ａが設けられたものであり、地下構造物用蓋２は、下方と内側が開放され、内圧解放口７ａにつながった解放流路７ｂを有する。【選択図】図５
