GUARD FENCE FOR ROAD FOUNDATION MEMBER, GUARD FENCE FOR ROAD, AND CONSTRUCTION METHOD THEREOF
To provide a guard fence for road foundation member, guard fence for road, and construction method thereof capable of suppressing a sudden decrease in the supporting force of the entire guard fence for road and, consequently, suppressing a large deformation of a fence member.SOLUTION: A base member buried in the ground to support a post of a guard fence for road, includes: a wall-shaped member 1 having a hollow portion 1a for receiving the post, and formed to be long in a road extending direction; and a rotation suppressing member 2 provided to protrude toward a roadway side V and/or a sidewalk side W of the wall-shaped member 1. The wall-shaped member 1 is formed by joining any one or a combination of two or more of a hollow square steel pipe 11, an H-shaped steel, a bent steel plate, and a flat steel plate.SELECTED DRAWING: Figure 1
【課題】道路用防護柵全体の支持力の急激な低下、ひいては柵部材の大きな変形を抑制することができる、道路用防護柵の基礎部材及び道路用防護柵並びにその構築工法を提供する。【解決手段】地中に埋設されて道路用防護柵の支柱を支持する基礎部材であって、前記支柱を受け入れる中空部１ａを備え、道路延長方向に長く形成された壁状部材１と、前記壁状部材１の車道側Ｖ及び／又は歩道側Ｗへ突き出して設けられる回転抑止部材２とから成る。前記壁状部材１は、中空角形鋼管１１、Ｈ形鋼、折り曲げ鋼板及び平鋼板うちのいずれか１つ又は２つ以上の組み合わせで接合してなる。【選択図】図１
