Description

Wire fixture for slope reinforcement and slope reinforcement device having the same {Wire fixture for stiffening slope and apparatus for stiffening slope comprising the same}

The present invention relates to a wire reinforcing device for slope reinforcement and a slope reinforcing device having the same, and more particularly, a slope reinforcing wire fixture for fixing a cross section of a wire supporting a protection net of a slope reinforcing device and a slope reinforcing device having the same. It is about.

In general, slopes installed in conjunction with large-scale land construction, roads, railways, etc. are largely susceptible to natural disasters. Therefore, in order to secure the stability of the slope development of the slope reinforcing device is actively progressing.

Slope reinforcement device has been used a different method according to the characteristics of the slope. For example, when it is difficult to increase the shear force, such as a weathering band or a cladding layer, a method of lowering the inclination angle of the slope is used.

In the case where the condition of the rock is good but the shear force of the discontinuous surface is a problem, a method using a rock bolt or a cable is used. In addition, in the case of steeply adjusting the slope of the slope, a method such as providing a retaining wall was used.

Conventional slope reinforcement device stabilizes the slope by using a high elastic high pressure crimping network. The slope reinforcement device according to the prior art increases the shear resistance of the slope by using the slope reinforcement material and the high-strength high elastic wire mesh material to stabilize the slope, and to make an environment-friendly slope by greening the slope.

However, a gap may occur between the upper surface of the reinforcing member hole where the reinforcing member is installed and the pressure plate due to weathering and erosion. As a result, the pressure plate is unable to maintain a state in contact with the slope, and as a result, the fixture has a problem in that it is not possible to continuously fix the pressure plate in a compressed state on the slope.

In addition, this high-strength high elastic wire mesh is installed in a narrow mesh over the entire slope, and the processing of the wire mesh requires a considerable cost, so there is an economic burden in the production of the wire mesh, and between the pressure plate and the surface of the reinforcement member in the slope reinforcement device Due to erosion, the pressure plate and the fixture are not able to compress the wire mesh on the slope, so the wire mesh installed on the entire slope floats on the slope, and the resilience of the wire mesh is weak.

Conventional slope reinforcing wire fixtures for solving the problems of the conventional slope reinforcing device is disclosed in Japanese Patent Laid-Open No. 2006-0006206.

The pressure plate 140 is installed on the erosion prevention means 160 and the wire 120, the elastic force of the elastic member 170 installed on the top of the pressure plate 140, the wire 120 and the erosion prevention Transfer to means 160 to press them. In addition, the pressure plate 140 also serves to fix the reinforcing member 130 installed on the slope by the combination of the elastic member 170 and the fixing means 150.

Erosion preventing means 160 is installed on the surface of the reinforcing member hole in which the reinforcing member 130 is installed serves to prevent the erosion of the slope around the reinforcing member hole. The elastic member 170 is installed at the upper end of the pressure plate 140, and serves to compress the erosion preventing means 160 and the pressure plate 140. The fixing means 150 is installed on the upper portion of the elastic member 170, and serves to fix the compressed state of the elastic member 170.

Thus, the conventional wire reinforcement for slope reinforcement is configured to hold the upper portion of the pressure plate 140 and the wire 120 on the slope, or when the load of rockfall or soil discharged from the slope is excessive, the load cannot be tolerated. There is a problem of breakage.
