The anti-falling stone network is installed and the wire rope is installed organically and firmly, And when the ground motion So that the slope can be supported and stabilized.
Description
The present invention relates to a rockfall prevention network fixing structure, and in particular, to a rockfall preventing network fixing structure, in which a wire rope provided on a surface of a rockfall prevention network acts organically to firmly support a slope, To a rockfall prevention network fixing structure.
In general, in the area where rockfall is likely to occur, a large number of wire ropes are installed on the top surface of the rockfall preventing net to secure the crossing portion of the wire rope to secure the rockfall preventing network. To prevent accidents.
However, this conventional technique has not been able to more effectively fix the wire rope provided on the surface of the fall-preventing network, thereby deteriorating the anti-rocking effect.
Accordingly, the conventional technology includes Patent Registration No. 10-0642141 and Patent Registration No. 10-0651655 filed by the present applicant.
Therefore, the main object of the present invention is to provide a rockfall prevention network fixing structure which is provided with a rockfall prevention network and is installed organically and firmly so that the rockfall can be generated and the supporting force can be efficiently exerted in the ground motion to support and stabilize the slope have.
In order to achieve the above object, according to the present invention, there is provided a rockfall prevention network fixing structure, comprising: a wire rope fastener having a guide groove for guiding a wire rope on each of the facing surfaces of the upper and lower plates, A connecting chain having an impact absorbing tube for connecting one end to the fixing member and absorbing impact energy; a strut supporting the fixing member by connecting the other end of the connecting chain; A rotation guide hole for adjusting the supporting force, and an escape preventing member for guiding the connecting chain by being coupled to the rotation guide hole.
Therefore, when the impact energy is transmitted to the rockfall preventing network and the wire rope, the supporting structure of the rockfall preventing network fixing structure of the present invention doubles the supporting force by the connecting chain connecting the fixing member and the support, Absorbing energy is absorbed by a plurality of shock absorbing tubes so that the shock absorbing tube absorbs the impact energy due to the pressure generated in the slope, So that it is possible to efficiently protect the slope and also to prevent a large accident by suppressing the intrusion of the rockfall or the slope caused by the collapse on the slope.
