When creating a JJ hole, use a water jet to cut a slit along the tunnel boundary line to form a sharp point to obtain a smooth tunnel cross section.
It is possible to pull out the black kite from the hole, or when inserting it into the hole, by applying a high pressure jet from the nozzle to the bedrock and drilling it into the bedrock, which can be done economically and in a short time. This is to obtain a smooth tunnel cross section by cutting the outer circumferential slit.
Because a high-pressure hose was used, a lance with a special high-pressure hose was used, so it took time to replace it. If we apply this invention to the example shown in Figures 1.2.3 and the amount of paddy, Figure 1 shows a rock mass 1, a rock machine 6, a leader 19,
The charging hole 2 is drilled through the bolt hole (2), which consists of the joint 12, rod 5, pi/nod 3, and tip 4. When the hole is finished, the high pressure jf81 high pressure pipe in the Orad is 17, high pressure foot port 11, connection direction 32, joint 12, seal 21,
High-pressure water is sent to the pipe 8 from the joint pipe 18 and the high-pressure atto inlet 20, and 14 jets are ejected from the nozzle at 13 through the connection at 10.9 to cut 15 atto into the rock. . In this case, the low pressure 2 which is necessary for rock drilling is 2. Since it protrudes from the exit J, a hole is created. Note that for the high pressure H, β1 remains the same even if 7 rotation joints are used. In addition, the connection 10.9 between the joint 12 and the high pressure L#8 is made by mounting the nut 25 of the pipe 8 on the shank on the second jig 1, the valve seat 26' on the locking 27, and the 7 Lange attached to the joint 118. 24, Porto 23,
Since the valve 26 is in close contact with the valve seat 26', there is no leakage of high pressure water.
Sent without any trouble. In addition, if you buy the stopper 22 on the joint pipe 18 at a suitable length, when the joint 12 and the rod 5 are separated, the joint of the high pressure pipe can be easily removed, and when the rod is connected, High pressure pipes can also be connected.

The high pressure 9 of 31 is connected to the sheath and tube.
