DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is suitable for use in, for example, a slope of a tunnel pit, a dam, a side wall of a road, or the like, or a rock bolt for reinforcing a deep foundation pile under construction. The present invention relates to a method for driving a lock bolt and a lock bolt driving machine.

[0002]

2. Description of the Related Art As is well known, when a slope is formed by excavating rock or earth and sand, the slope is prevented from collapsing.
The slope is reinforced by spraying concrete, forming a grid-like concrete frame (so-called free frame) along the slope, or driving rock bolts. At this time, the lock bolt is not only cast alone, but may be used in combination with sprayed concrete or a free frame. In addition, for the purpose of preventing landslides and increasing the bearing capacity, there are cases where a deep foundation pile is constructed by digging a hole in the ground and using a reinforcing bar or a steel concrete structure inside. If you do
The rock bolt method is applied to the hole wall to stabilize the ground during construction.

Conventionally, in order to drive a rock bolt into the ground as described above, first, a work scaffold is constructed along a slope or a hole wall surface. Then, a rock drill is installed on the working scaffold so as to face the slope or the hole wall surface, and a hole for driving a rock bolt is drilled. At this time, water or air is jetted from the tip of the bit of the rock drill to discharge the drilling debris generated by the drilling. Next, an injection hose is inserted into the drilled hole, and mortar or cement milk is filled up to the mouth of the hole. Thereafter, a lock bolt is inserted into a hole filled with mortar or cement milk, and then a bearing plate and a nut are attached to the lock bolt at the mouth of the hole, thereby fixing the lock bolt.

[0004]

However, the above-described conventional method for setting a bolt and a machine for setting a bolt have the following problems. First,
Since the work scaffold must be installed on the entire slope and on the perforated wall, the assembling and removing work after the completion of the construction requires a great deal of labor and cost, which hinders shortening of the construction period. In addition, rock drills are used for drilling holes for placing rock bolts. However, operators must perform all operations such as moving and operating the rock drills. Has been a painful task. In recent years, in order to solve this problem, a device equipped with a drilling machine in a working vehicle equipped with a boom has been developed and put into practical use, but as always, a work of filling mortar and cement milk other than drilling, and Regarding the insertion work of the lock bolt, there is no change that the worker works on the work scaffold, and there is room for improvement in terms of work efficiency, safety, work environment and the like.

[0005] The present invention has been made in view of the above points, and aims to improve the efficiency of the work of driving a lock bolt on a slope, shorten the construction period, reduce costs, improve safety and work environment. It is an object of the present invention to provide a lock bolt driving method and a lock bolt driving machine capable of improving the performance.
