FIELD OF THE INVENTION [0001] The present invention relates to a wire net assembly with a female connector,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire net assembly with a arm and a method of manufacturing the same. More particularly, the present invention relates to a wire net assembly with a arm, , It effectively absorbs the initial behavior energy of the slope to suppress the collapse of the slope and to warn of the occurrence of the slope. In this way, it is possible to prevent safety accidents due to collapse of the slope in the initial response, And a method of manufacturing the same.

Generally, when constructing a road including a mountainous area, an incision plane or an inclined plane is artificially formed due to cutting or the like. On this incision plane or slope plane, the discontinuity of the discontinuity in the rock causes the rock to separate from the parent rock, As well as being able to collapse rocks in large-scale collapse, there is concern about the establishment of rockfall prevention facilities.

The construction of such an anti-rockfall facility is divided into a reinforcement method and a protection method according to the function. The reinforcement method includes cutting method, surface preparation, anchor, rock bolt, concrete brace wall, concrete block method, shotcrete, The construction method includes the rockfall prevention network, the anti-rocking fence, the anti-rocking retaining wall, the phylactic tunnel, and the vegetation construction method.

An example of a fall-prevention network is a wire rope in which protective nets are cut on cut slopes or slopes and wire ropes of longitudinal and transverse directions are disposed thereon at regular intervals. The intersections of these ropes are fixed by fasteners or fixed to the ground by anchor bolts A safety net is used, thereby preventing the occurrence of rockfall on the incision surface or the inclined surface, and guiding the rockfall under the rockfall prevention network so that the rock is not splashed when the rockfall occurs, thereby preventing various accidents.

The wire rope safety net is largely classified into a pocket type and a curtain type. The pocket type safety net makes a PVC-coated net close to a rock wall, intersects the wire rope in the longitudinal direction and the lateral direction at intervals of several meters, The anchor bolt is fixed to the rock to increase the supporting force of the PVC coated net and the wire rope in order to increase the resistance of the wire rope at a fixed position. The curtain type safety net is provided with an anchor bolt And anchor bolts are reinforced only on the left and right sides, and it is mainly used in the incision surface composed of soft rock or weathered rock, which is mainly cracked in rock and weathering progresses rapidly.

Korean Patent Laid-Open Publication No. 2001-0086663 (published on Sep. 15, 2001) discloses a core material inserted into a plurality of holes perforated in a lattice pattern on a cut slope, A plurality of reinforcing members formed of grouting injected into the reinforcing member; A plate-shaped pressure plate having a hole formed at the center thereof to insert the core member; And a wall protruding along the lower surface of the flat plate. The flat plate is formed at its center with a hole through which the core of the reinforcing material is inserted, A fixation port having a plurality of guide holes; A liner screw and a nut for fixing and fixing the core of the stiffener on the fixation port; And a connecting wire inserted through the guide hole of the fixing hole to bind a plurality of fixing holes provided in a lattice shape to each other.

In addition, Korean Patent Laid-Open Publication No. 10-2010-0138967 (published on Dec. 31, 2010) discloses a net assembly including a rope member coupled in the cross direction and a wire net connected to the rope member, Wherein the anchoring and netting assembly is configured to inhibit movement of the identified rock mass on the slope, wherein the anchoring and netting assembly comprises a plurality of anchors that are inserted into the slope inwardly to stabilize the surface layer of the slope, A rock-fall preventing structure having a sufficient strength for preventing the occurrence of a crack is disclosed.

However, when the wire rope safety net of this prior art is installed such that the surface of the incision surface is cut due to blasting or the like so that the surface of the incision surface is rough or uneven, the incision surface is large in curvature and the inclined surface protruding from the rock is wrapped, There is a problem that the supporting force of the wire rope is weakened and the restraining force of the falling rock is deteriorated and the mass of rock is easily separated to cause various accidents.

The wire rope safety nets of the prior art are complicated in connection and installation of wire ropes in the longitudinal and transverse directions and are fixed by connecting the fixtures used at the intersections with bolts so that the wire rope can not be stably fixed to the inclined surface .

In order to solve such a problem, Korean Patent Registration No. 10-1484005 (published on Jan. 26, 2015) filed by the applicant of the present application has been proposed, but it can not efficiently absorb the pressure due to the ground motion, The installation and construction takes a long time, and the behavior of the slope can not be easily recognized.
