Abstract

PROBLEM TO BE SOLVED: To drive a rock bolt to stabilize the ground against a slope ground surface of a mountain without assembling a scaffold for erection of a guide shell necessary for use of an air light drifter, or without practically cutting down living trees. SOLUTION: A base plate 9 having a specified area kept in contact with the ground surface is fitted to the tip of a guide shell 2 for guiding an air light drifter 1 for driving a rock bolt 3, within a specified range of length. At least two wires 12a, 12b for fixing the head are attached to the upper end of the guide shell and also two or more wires for fixing the lower part are attached to the lower end thereof. The other ends of respective wires are pulled and connected to an anchor 15 driven in the ground surface separated by a specified distance, or a living tree 14 or the like. In this way, the guide shell is fixed so as to be erected on the ground. The air light drifter 1 is transferred along the guide shell 2 in this state and the rock bolt 3 is driven.

FIG. 4 shows a non-frame construction method which is performed today. In the figure, 1 is an air light drifter for driving a rock bolt,
While being guided by the guide cell 2, the air light drifter 1 drives the lock bolt 3 attached to the tip of the air light drifter 1 into the ground of the slope S. That is, since the length of the lock bolt 3 to be driven is long, such as 2 m, 3 m,..., The guide cell 2 is used, and for this purpose, the scaffold 4 is attached to the inclined surface S. I,
For this purpose, it is necessary to make a complicated scaffold, that is, it is necessary to carry in and assemble the scaffold pipes, and it is unavoidable to cut down some of the standing trees which hinder the scaffolding. The present invention is a construction method that eliminates the need for the scaffolding described above and that can eliminate the cutting of standing trees.

In the present invention, as shown in the above example, the guide cell 2 is fixed by using two wires at each of the upper and lower portions thereof and pulling the guide cell 2 in a triangular wing shape toward the upper side of the inclined surface S. In this case, setting the opening angle θ of each of the upper and lower wires in the range of 30 ° to 90 °
The guide cell 2 can be stably set up.
Further, it is preferable that the guide cell 2 is erected perpendicularly to the ground surface so as to drive the lock bolt. However, since the driving angle θ ′ is generally in the range of 90 ° to 30 °, is there. It is the simplest way to hook up the two wires at the upper and lower parts of the guide cell 2. However, if it is difficult to hook up the wire as described above in the field, the auxiliary wire 17 may be appropriately connected to the left and right of the guide cell, for example. For example, the vehicle is towed in a lateral direction, and this is performed flexibly according to the condition of the ground surface at the site.

[0010] In the present invention, the above-mentioned wire hooking is generally carried out by using a standing tree 14 in the vicinity. If the standing tree is too thin to withstand a tensile force, an anchor is separately driven into the ground surface. This is done by using this, and as long as it does not get in the way at the place where the rock bolt is driven,
4 can be implemented without cutting down.
