Embodiment Construction

[0036] The embodiments explained below should in no way be construed as limiting the content of the invention described in the patent claims. Similarly, all configurations explained below are not necessarily essential conditions of the present invention. Each of the embodiments explained hereinafter describes a rock fall prevention structure and a rock fall prevention method that have never been done in the prior art, and by a new method different from the prior art The rock fall prevention structure and the application of the rock fall prevention method are obtained.

[0037] Refer below Figure 1 to Figure 6 A first embodiment of the present invention will be described. As shown in the figure, the rockfall prevention structure covers the slope 1 using a net assembly 2 consisting of vertical and horizontal rope material 3, 4 and wire net 5, these vertical and horizontal rope materials 3, 4 are combined in a crossed direction, and the wire net 5 is connected to these rope m...

Abstract

To provide rock fall prevention structure and rock fall prevention method capable of preventing the collapse of surface layer and preventing the falling of identified rock masses. Slope (1) is covered with a net assembly (2) constructed of rope materials (3) and (4) combined in intersectional directions and a wire net connected thereto. The rope materials (3) and (4) of the net assembly (2) are anchored into slope (1) using anchors (6). The anchors (6) are inserted into slope (1) to stabilize a surface layer of the slope (1), giving the anchors (6) and the net assembly (2) a strength able to suppress the movement of identified rock masses (22) at slope (1). Using the anchors (6) will be able to prevent the surface layer of slope (1) from collapsing and at the same time, using the anchors (6) and the net assembly (2) will be able to suppress the movement and falling of the identified rock masses (22) at slope (1).

Description

technical field [0001] The present invention relates to a rockfall prevention structure, a rockfall prevention method, and a design method of the structure for preventing rockfall. Background technique [0002] In the prior art, as such a rock fall prevention structure, a method of driving an anchor into a slope requiring stabilization (as in Japanese Unexamined Patent Publication No. 2007-262734) is known, and Also known is a method of covering a slope using a net assembly consisting of a combined vertical and horizontal rope material and a net covering this combined vertical and horizontal rope material, and then passing the vertical ropes through buffer means. The upper end of the material and both ends of the horizontal rope material are fixed to the slope, and the net assembly is fixed to the slope (as in Japanese Unexamined Patent Publication No. JP 2002-227140). [0003] According to the method in JP 2007-262734, it is possible to restrain the slope surface from coll...
