낙석방지망용 와이어로프 조립구{Construction apparatus of wire rope for a preventive measure of falling rock}Construction apparatus of wire rope for a preventive measure of falling rock}

본 발명은 낙석방지망용 와이어로프 조립구에 관한 것으로, 더욱 상세하게는 낙석이나 붕괴가 예상되는 비탈면에 낙석방지망을 밀착시킨 후 암반에 고정되도록 와이어로프를 설치할 때 와이어로프가 지탱되는 앵커의 조립구를 2열의 와이어로프가 교차되도록 구성함에 따라 낙석방지망을 암반에 밀착되게 하는 와이어로프의 장력을 배가시켜 견고성과 안전성을 향상시킬 수 있게 한 낙석방지망용 와이어로프 조립구에 관한 것이다.The present invention relates to a wire rope assembly for rockfall prevention network, and more particularly, the assembly of the anchor that the wire rope is supported when the wire rope is installed to be fixed to the rock after the rockfall prevention network is in close contact with the slope that is expected to fall or collapse The present invention relates to a wire rope assembly for rockfall prevention nets that can improve the robustness and safety by doubling the tension of the wire ropes that make the rockfall protection net close to the rock as the two rows of wire ropes intersect.

일반적으로, 바위로 된 절개지의 비탈면이 우수 또는 결로 등으로 인하여 붕괴되거나 낙석이 예상되는 개소에 낙석방지망이 설치되며, 상기 낙석방지망은 그 외측에 격자상으로 설치한 와이어로프에 의해 암반에 밀착 고정되어 비탈면으로부터 결합력을 상실한 암석을 구속하게 된 것으로, 와이어로프의 각 교점마다 앵커에 의해 지탱되게 하고, 상기 와이어로프의 설치간격 및 앵커의 길이는 현장 여건을 감안하여 결정하였다.In general, a rockfall protection net is installed at a location where a slope of a rock cutout is collapsed due to rain or condensation or a rockfall is expected, and the rockfall protection net is closely fixed to a rock by a wire rope installed outside the grid. As a result, the rock which lost the bonding force from the slope was restrained by the anchor at each intersection of the wire rope, and the installation interval and the length of the anchor of the wire rope were determined in consideration of the site conditions.

상기 낙석방지망을 시공하기 위한 일 예로서, 낙석방지망을 암반에 밀착되게 한 상태에서 앵커볼트(이하, "앵커"라고 약칭함)는 암반의 절리를 점검하여 천공깊이와 간격을 결정한 후 천공하고, 상기 천공 구멍 내에 앵커를 삽입한 후 충전용 수지를 주입 및 적당시간 이상 양생하여 앵커와 암반이 일체가 되도록 시공한 후 상기 앵커에 조립구를 결합한 상태에서 이에 와이어로프를 팽팽하게 당겨 낙석방지망을 고정되게 하는 방법이 보편적이었다.As an example for constructing the rockfall prevention net, anchor bolt (hereinafter referred to as "anchor") in a state in which the rockfall prevention net is in close contact with the rock is determined by checking the joint depth of the rock to determine the depth and distance of drilling, After inserting the anchor into the hole, the filling resin is injected and cured for more than a suitable time, so that the anchor and the rock are united, and then the wire rope is pulled tightly to fix the rockfall prevention net while the assembly is coupled to the anchor. The way to make it was universal.

도 1은 종래의 낙석방지망의 시공 예를 나타낸 것으로, 비탈면(R)의 암반에 낙석방지망(M)을 밀착되게 한 후 적당 간격으로 배치되어 있는 각각의 앵커(1)에 조립구(2)를 결합하고 이에 한 줄의 와이어로프(W)를 교차로 지탱되게 고정함으로써 낙석방지망을 부분적으로 암반에 고정시키게 된 것이다.Figure 1 shows a construction example of the conventional rockfall prevention net, the assembly (2) to each anchor (1) arranged at appropriate intervals after the rockfall prevention net (M) in close contact with the rock of the slope (R) By joining and fixing a row of wire rope (W) to the cross-bearing to be fixed to the rockfall protection net partially to the rock.

그러므로 낙석방지망이 시공된 구간의 암반에 기후변화 및 지각변동에 의해 균열이 발생되고 이러한 균열이 심화되면서 비탈면으로부터 암석이 떨어져 나오게 될 경우 상기 낙석방지망에 의해 암석을 구속되게 하여 비탈면의 유실이나 붕괴를 방지하였다.Therefore, if the rock is generated by climate change and tectonic change in the rock where the rockfall protection network is constructed, and the rock is separated from the slope as the crack is intensified, the rock is bound by the rockfall prevention network, causing loss or collapse of the slope. Prevented.

그러나 종래에는 암석을 구속되게 하는 낙석방지망이 한 줄의 와이어로프를 교차되게 함으로써 얻어진 장력에 의해 비탈면에 고정되어 있으므로, 낙석방지망의 어느 특정부위에서 많은 량의 암석이 분리되어 과도한 하중이 가해질 경우 낙석방지망이 터지거나 와이어로프가 절손되면서 낙석사고가 빈번하게 발생하는 문제점이 있었다.However, in the past, the rockfall protection net, which causes the rock to be constrained, is fixed to the slope by the tension obtained by crossing a row of wire ropes. Thus, when a large amount of rock is separated from a certain portion of the rockfall protection net and excessive load is applied Falling protection nets or wire ropes were broken, there was a problem that frequently occurs rockfall accidents.

즉, 비탈면에서 분리된 암석이 낙석방지망의 어느 한 부위로 집중되면서 그 내구성능을 초과하는 하중이 가해질 때 암반에 밀착되어 있던 낙석방지망이 볼록한 상태로 변형이 발생되고, 특정 부위의 낙석방지망에 가해진 변형으로 인하여 그 인접구간의 앵커를 교점으로 지탱되어 있는 와이어로프에도 과도한 하중이 가해지면서 변형이 유발됨으로써, 변형이 가해진 낙석방지망과 와이어로프에 피로가 집중될 때 파손이 발생되어 낙석이나 붕괴나 일어나는 문제점이 발생하였다.That is, when the rock separated from the slope is concentrated to any part of the rockfall protection net, when the load exceeding its durability is applied, the rockfall protection net that is in close contact with the rock is convex, and the rockfall protection net of the specific part is applied Deformation causes excessive load on the wire ropes holding the anchors of the adjacent sections as an intersection, causing deformation, which causes breakage and collapse or collapse when fatigue is concentrated on the applied rockfall protection nets and wire ropes. A problem occurred.

본 발명은 위와 같은 종래의 낙석방지망을 지탱하는 와이어로프의 내구력 저하로 인한 문제점을 감안하여 발명한 것으로, 그 목적은 비탈면에서 분리된 암석이 낙석방지망의 특정부위에 집중될 때 가해지는 하중을 2열로 교차되게 설치한 와이어로프에 의해 분산되게 하는 낙석방지망용 와이어로프 조립구를 제공하는 것이다.The present invention has been made in view of the problems caused by lowering the durability of the wire rope supporting the conventional rockfall prevention net as described above, the object of which is that the load applied when the rock separated from the slope is concentrated on a specific portion of the rockfall prevention net It is to provide a wire rope assembly for rockfall prevention network to be dispersed by a wire rope installed to cross the heat.

이러한 목적을 달성하기 위한 본 발명은, 낙석이나 붕괴가 예상되는 비탈면의 암반에 낙석방지망을 밀착되게 설치하고, 상기 낙석방지망이 위치하는 암반의 다수 곳에 적당한 간격으로 배치되게 앵커를 설치하여 암반의 외부로 돌출된 앵커에 결합 설치되는 조립구에 의해 와이어로프를 지탱하여 낙석방지망을 고정되게 할 때, 상기 와이어로프가 지탱되는 조립구를 사방에서 와이어로프를 각각 클램핑할 수 있도록 십자형으로 분기되게 형성하여 어느 한 지점의 앵커를 교점으로 설치되는 와이어로프를 2열로 교차되도록 구성함으로써, 와이어로프의 설치를 용이하게 하면서 낙석방지망을 고정 지탱하는 와이어로프의 장력을 배가시킬 수 있도록 한 것을 특징으로 한다.The present invention for achieving this object, the rockfall is installed in close contact with the rock surface of the rock surface is expected to fall or collapse, and the anchors are installed at appropriate intervals in many places of the rock where the rockfall prevention network is located outside of the rock When fixing the rockfall prevention net to support the wire rope by the assembly to be coupled to the anchor is installed in the protruding anchor, to form a cross-shaped branch so that the wire rope can be clamped to the assembly to support the wire rope from each side By configuring the wire rope installed in the intersection of the anchor point of any one point in two rows, it is characterized in that to facilitate the installation of the wire rope while doubling the tension of the wire rope holding the rockfall prevention net fixed.

이와 같은 본 발명의 낙석방지망용 와이어로프 조립구는 와이어로프가 지탱되는 앵커의 조립구를 2열의 와이어로프가 교차되도록 구성함에 따라 종래에 1열의 와이어로프를 교차되게 앵커에 지탱할 경우에 비해 약 2배 정도로 확대된 장력을 얻을 수 있게 되어 견고성을 향상시킬 수 있다.As described above, the wire rope assembly for the rockfall prevention net of the present invention is constructed so that the wire rope is supported by the assembly of two rows of wire ropes intersecting the anchors. The tension can be obtained to an extent that can be improved to improve the robustness.

또한 본 발명은 2열의 와이어로프에 의해 낙석방지망을 고정시키게 됨으로써, 낙석방지망의 어느 특정부위의 암석이 쌓이면서 하중이 가해질 경우에도 낙석방지망을 고정되게 지탱하는 2열의 와이어로프가 암석의 하중을 분산하게 되므로 낙석방지망 또는 와이어로프의 손상과 피로파괴 등을 최소화하여 안전성을 향상시킬 수 있는 장점도 있다.In addition, the present invention is to fix the rockfall prevention net by two rows of wire rope, so that even if a load is applied to the rock deposits of any part of the rockfall prevention net, the two rows of wire ropes to hold the rockfall prevention net fixedly to distribute the load of the rock Therefore, there is an advantage that can improve the safety by minimizing the damage and fatigue fracture of rockfall prevention net or wire rope.
