To provide a guard fence for a manhole which is good at stability during use, facilitates a working person to access, allows a person or an object to effectively prevent from falling into the manhole, and is capable of being stored in a compact manner after use.SOLUTION: A guard fence 100 for a manhole is provided with: a jack base 15 arranged on a lower ends 11b to 14b of respective columns 11 to 14 erectable on an installation surface G; beam members 21 (22) to connect columns 11, 13 (12, 14) to each other arranged to form an X-shape on upper ends 11a to 14a of the columns 11 to 14; an axial body 20 pivotably supporting the beam members 21, 22; an outer frame 40 arranged in lower areas of side surfaces 32 to 34 among side surfaces 31, 32, 33, 34 of a virtual square cylindrical body 30 formed with the columns 11 to 14; an open/close member 50 arranged in a lower area of the other side surface 31; and an elastic member 46 sealing a gap between the installation surface G and a lower edge member 41 of the outer frame 40.SELECTED DRAWING: Figure 1
【課題】使用中の安定性が良好であり、作業者の出入りが容易であり、マンホール内への人や物の落下を有効に防止することができ、使用後はコンパクトに収納可能な、マンホール防護柵を提供する。【解決手段】マンホール防護柵１００は、設置面Ｇに立設可能な支柱１１〜１４の下端部１１ｂ〜１４ｂに設けられたジャッキベース１５と、支柱１１〜１４の上端部１１ａ〜１４ａ側にＸ状をなすように配置され支柱１１，１３（１２，１４）同士を連接する梁材２１（２２）と、梁材２１，２２を回動可能に軸支する軸体２０と、支柱１１〜１４で形成された仮想四角筒状体３０の側面３１，３２，３３，３４のうちの側面３２〜３４の下方領域に配置される外枠４０と、残余の側面３１の下方領域に配置される開閉部材５０と、設置面Ｇと外枠４０の下縁部材４１との隙間を閉塞する弾性部材４６と、を備えている。【選択図】図１
