DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, with reference to the drawings, specific details for implementing an open-close type rockfall prevention measure according to the present invention will be described in detail with reference to examples.

2 and 3, the open-close type rockfall prevention device 1 according to the present invention is installed on the road side having a slope to prevent rocks to protect people and properties, and includes a support 100, a cross clip 200, A main wire 300, a turnbuckle 400, a reinforcement wire 500, a fall-prevention network 600, and a spacing pad 700.

The column 100 includes a main body 110 and a column 110. The main body 110 includes a plurality of columns 100 disposed at predetermined intervals along a road R having slopes S A top portion 120 formed at an upper portion of the main body 110 to prevent the bottom of the main body 110 from falling over the road R beyond the support pillars 100, And a lower end 130 which is fixedly mounted on the main body 110. The main body 110 is provided with a plurality of fixing clips 110 along the longitudinal direction as shown in FIG.

The struts 100 are formed of ducts, sections, and the like. The lower ends of the struts 100 are inserted into the ground surface of the road, and concrete is placed and cured inside the roads. A main wire 300 and a fall-prevention network 600, which will be described later, are connected to the strut 100 to close the struts 100, so that the fall is prevented from falling on the road R.

5 and 8, the intersecting clip 200 includes a plurality of spaced apart longitudinally spaced clips 140 in the inner space between the struts 100 and a securing clip 140 located on the upper side of the struts 100, The main wire 300 connected to the main body 100 passes through the cross clip 200 and returns to the side supports 100 and passes through the fixing clip 140 located at the lower side.

If the present invention employs a conventional method in which the wire ropes are cross-connected longitudinally and laterally at a plurality of intersections of the inner spaces between the struts, or crossed diagonally at a plurality of intersections to form a rhombus, Since a large number of intersecting clips are required and the wire rope is installed cross-linked to a large number of such intersecting clips, the number of members increases so that the opening and closing operations are complicated and time-consuming and costly. 300) are intersected, so that the opening and closing are made quick and easy.

5, the intersecting clip 200 is formed with a connecting piece 210 to which the main wire 300 and the reinforcing wire 500 can be connected, respectively, on the front surface and the rear surface, And the reinforcing wire 500 are connected to each other through the connecting piece 210.

For example, the connecting piece 210 may have a U-shaped ring formed on the front surface of the crossing clip so that the main wire 300 can be cross-connected at both sides, and a U- 500 may be passed in the vertical direction.

One of the main wires 300 is provided for each unit section between the struts 100 and 100. The main wires 300 extend from both sides of the upper portion 320 installed in the horizontal direction and pass through the fixing clip 140, 100 so as to extend from both sides toward the intersecting clip 200 and to be crossed with each other at the intersecting clip 200 and then to be returned to the side supports 100 and pass through the fixing clip 140 located at the lower side, The ends 310 of both sides of the main wire 300 pass through the lower end connection port 311 in a zigzag manner between the struts 100 and the intersecting clip 200, And the ring 312 is detachably connected to the moving member 420 of the turnbuckle 400 through the hole. Thus, opening and closing operations of the main wire 300 are quick and simple, and re-installation is easy after the separation operation.

Both ends 310 of the main wire 300 are connected to each other through the turnbuckle 400 and the turnbuckle 400 connects both ends 310 of the main wire 300 to the main wire 300, Or compression.

The turnbuckle 400 comprises a turnbuckle body 410 and a pair of movable members 420 connected to both sides of the turnbuckle body 410. The movable member 420 is connected to both ends 310 of the main wire 300 And the turnbuckle body 410 is disposed between the moving members 420. The turnbuckle body 410 is connected to the turnbuckle body 410 by a screw thread formed on the outer circumferential surface of the movable member 420, And the main wire 300 can be tightly supported on the support pillars 100 by tightly inserting an insertion groove having an inner peripheral surface on both sides of the turnbuckle body 410, 300 are prevented from loosening.

The reinforcing wire 500 is arranged in a vertical direction, and connects the plurality of intersecting clips 200. 6, the upper end of the reinforcing wire 500 is perpendicularly connected to the upper end 320 of the main wire 300 via the upper end connection port 321, The load applied to the main wire 300 or the fall-prevention network 600 can be effectively transmitted to the support. At this time, the lower end of the reinforcing wire 500 may be connected to the ground.

Referring to FIG. 9, the rockfall prevention network 600 is connected to surround the rear of the open-close type rockfall prevention device 1, and is made of a PVC coated net coated with galvanized iron wire having excellent durability. At this time, the reinforcing wire 500 can be installed inside and outside of the fall-preventing network 600 so as to further increase the supporting force and resistance against the fall-down.

The spacing supporter 700 is disposed between the upper ends of the struts 100 and maintains the spacing of the struts 100 embedded in the base B and supports the struts 100, Allowing them to remain established in a straightforward state.

In the case where repair work or fall-stone removal work due to the occurrence of fall-down is required in the open-close type anti-fall prevention implement 1 constructed as described above, a part of the fall-fall prevention net 600 installed in the target unit section is cut open in the vertical direction, opened, The reinforcing wire 500 and the main wire 300 are separated from the clip 200 to separate and separate the reinforcing wire 500 and the main wire 300 from each other.

At this time, the turnbuckle 400 may be adjusted so that the main wire 300 is loosened and the both ends 310 of the main wire 300 are separated from the turnbuckle 400 And then perform the operation.

After completion of the repair work and the fall rock removal work, the main wire 300 disposed in the unit section is cross-connected with the cross clip 200 and the turn buckle 400 is adjusted to the main wire 300 And the reinforcing wire 500 is connected in the vertical direction along the intersecting clips 200. In this case,

At this time, if the main wire 300 is excessively stretched, a portion of the main wire 300 may be cut to provide a proper tension, and then the end portion 310 may be connected to the turnbuckle 400.

As a result, the open-type rockfall prevention device (1) according to the present invention is constructed such that the rockfall prevention device is opened and closed for each unit section, so that the maintenance work and the rockfall removal work due to the rockfall occurrence are simple, quick and efficient, And the members are minimized, so that the opening operation is simple, re-installation of the anti-rocking measures after operation is easy, and the effect of blocking the rockfall is excellent.

The present invention is not limited to the above-described embodiments. Anything having substantially the same constitution as the technical idea described in the claims of the present invention and achieving the same operational effect is included in the technical scope of the present invention.
