PROTECTING STRUCTURE OF JUMPING-OUT OBJECT FROM SLOPE
To absorb energy of a jumping-out object such as an anchor head or a falling rock using a simple method to protect jumping-out.SOLUTION: A cylinder 17 into which a friction material 23 is inserted is arranged in an anchor head capture device 10 receiving an anchor head 3, and a pushing member 27 capable of pressing the friction material 23 is provided to form a protecting structure 30 for the anchor head (a). When the anchor head capture device 10 is pressurized in a direction of arrow 33, its lower surface 10a rises by a length a1 from its initial position, and at the same time, the pushing member 27 compresses the friction material 23, and the restrained and deformed friction material 23 generates strong friction between itself and an inner surface of the cylinder 17. In a state where an upward energy of the anchor head capture device 10 is converted into the frictional energy, an upper surface 17a of the cylinder 17 rises by a length a2 (b). The anchor head capture device 10 can prevent a rise that is more than a length a1 from the initial position, and satisfies [a2]<[a1] or [a2] ≒ 0.SELECTED DRAWING: Figure 2
【課題】アンカーヘッド等や落石等の飛出し物のエネルギーを、簡易な方法により吸収して、飛出しを防護する。【解決手段】アンカーヘッド３を受けるアンカーヘッド捕獲具１０に、摩擦材２３を挿入したシリンダー１７を配置し、摩擦材２３を押圧できる押し込み材２７を設けてアンカーヘッドの防護構造３０とする（ａ）。アンカーヘッド捕獲具１０は矢示３３方向に加圧された場合、その下面１０ａは当初位置から長さａ１上昇し、同時に押し込み材２７が摩擦材２３を圧縮し、拘束され変形した摩擦材２３はシリンダー１７の内面との間に大きな摩擦が生じる。アンカーヘッド捕獲具１０の上昇エネルギーはこの摩擦エネルギーに変換された状態で、シリンダー１７の上面１７ａは、長さａ２上昇する（ｂ）。アンカーヘッド捕獲具１０は、当初置から長さａ１以上の上昇を防止でき、かつ「［ａ２］＜［ａ１］」又は「［ａ２］≒０」となる。【選択図】図２
