A guide mounting 26 is supported on the guide rotary 24 by a mount shaft 27, and the guide shell 26 is supported by the guide mounting 26 so as to be slidable back and forth. A rock drill 9 is mounted on the guide shell 6. A rod 8 having a bit 7 attached to the tip thereof is inserted into the drilling machine 9, and is fed in the front-rear direction on the guide shell 6 to drill the rock face 10 of the face.

By the way, in the movable part such as the boom of the punching machine Q, mechanical backlash and bending of members accumulate due to repeated use in a harsh environment and conditions in the tunnel. However, a position error occurs. For this reason, the position of the bit 7 of the rock drill often deviates from the desired position, and the accuracy of drilling hole positioning is significantly reduced due to the error in the position. Due to this decrease in accuracy, there is a possibility that the excavation of the outer circumference of the tunnel will be insufficient.

Conventionally, in order to avoid this shortage of excavation,
As shown in FIG. 6, 5 to 5 are drawn from the planned contour line PL of the tunnel.
An extra digging method of excavating along the construction contour line CL on the outside of about 10 cm is adopted, but because of the influence of this extra digging, it is necessary to place an extra concrete EC when finishing the outer wall of the tunnel. There was a problem that the construction period was prolonged and the cost was increased.

Therefore, in order to solve the problem of the decrease in accuracy, conventionally, after setting the punching machine Q near the site, the dimensions and movements of the movable parts such as the boom and the guide shell are measured again, and this again. An adjustment method that corrects the error is adopted for the computer control calculation model based on the measurement data, but this adjustment work is extremely complicated, and it must be performed regularly, and There was a big problem in terms of labor and cost.

The correction means 60 calculates a necessary correction value by executing the position error calculation program based on the detection value of the detector at the time of movement, and inputs it to the control device 50. The modified drilling can be accurately positioned by the controller 50.

An automatic tracking type surveying instrument 40 is installed behind the bogie 11 of the punching machine. This automatic tracking type surveying instrument 40
Has a built-in visible laser beam LB irradiation mechanism and can be rotated in the vertical direction and the horizontal direction by a command signal from the outside. The position data of the drilling position set by the control device 50 is transmitted from the wireless communication device 51 to the wireless communication device 41, and the automatic tracking surveying instrument 40 uses the received position data of the drilling position. Based on this, the laser beam LB is emitted toward the face.

The automatic tracking type surveying instrument 40 has a tracking function using infrared IR, and can perform distance measurement and three-dimensional coordinate measurement. Automatic tracking type survey instrument 4
The data measured by the wireless communication device 41 is transmitted from the wireless communication device 41 to the wireless communication device 51 on the carriage 11.
Is input to the control device 50. Further, in this drilling machine, a prism 3 for detecting the position of the guide shell 6 is installed at the rear end of the guide shell 6, and the position of the prism 3 is measured by an automatic tracking type survey instrument 40, and this measurement data is obtained. On the basis of the above, a function of determining the deviation of the drilling machine from the reference direction of the drilling machine and the position of the drilling machine reference point J with respect to the face 10 is provided.

Next, a method of correcting the positioning of the punch of the punch will be described by following the procedure of construction. First, the deviation of the reference direction of the drilling machine from the reference direction of the drilling machine and the position of the reference point J of the drilling machine with respect to the face 10 are obtained.
Specifically, after the bogie 11 of the punching machine is installed in the vicinity of the face 10, the telescopic boom 15 is moved from a position separated from the face 10.
The guide rotary 24 or the like is operated to bring the tip of the bit 7 into contact with a point on the face 10. The point on this face 10
It is a face reference point formed on the face by the laser beam LB emitted from the automatic tracking type surveying instrument 40 based on the position data set by the controller 50. Using this face reference point as the first measurement point, the automatic tracking surveying instrument 40 automatically tracks the prism 3 that moves with the movement of the guide shell 6 to measure the prism position B ₁ at the first measurement point. Next, the guide shell 6 is slid on the guide mounting 26 so that the tip of the bit 7 is separated from the face reference point, and is retracted to the second measurement point. This receding distance can be selected arbitrarily, but it is desirable to set it to a certain degree. Then, at the second measurement point, the automatic tracking survey instrument 40 automatically tracks the prism 3 that moves as the guide shell 6 moves backward, and measures the prism position B ₂ at the second measurement point.

Next, the first measurement data B ₁ on the face coordinate system
By comparing (X _l , Y _l , Z _l ) with the first measurement data B ₁ (x _l , y _l , z _l ) on the drilling machine coordinate system, the reference point J of the drilling machine with respect to the face is determined. Find the position. The data of the deviation of the reference direction and the position of the reference point thus obtained are set as an initial value for correction in the drilling control program of the computer of the controller 50. Then, the data of the drilling pattern set on the face coordinate system is controlled by the control device 50 based on the preset deviation of the reference direction and the data of the reference point position. The data is converted into pattern data and the drilling is controlled.

Normally, since it is not necessary to position the inside of the tunnel away from the contour line with high precision, the control device 50
Operates the movable parts such as the telescopic boom 15 based on the data of the drilling pattern, and the bit 7 of the drilling machine 9 is operated.
Is positioned at the calculated drilling hole position, and the positioning correction work is not performed. On the other hand, when starting the drilling work near the contour line of the tunnel, the drilling positioning correction work is performed. In this case, for example, as shown in FIG.

When the position irradiated by means of, there is no positioning error, it is possible to drill as it is. On the other hand, when it is positioned at the point D ₁ on the face 10 which deviates from the correction center point C ₁ , the operator moves the actual position of the bit 7 from the point D ₁ to the correction center point C as shown in FIG. _The control device 50 is switched to the manual mode so as to match with _1, and the operating means such as the operating lever is operated. The correction means 60 executes the position error calculation program from the detection data of the detector at this time, and the distance Δ from the point D ₁ to the correction center C ₁
(X , Y , Z ) Is calculated to obtain corrected data, which is input to the control device 50. Next, the operator controls the control device 5
By re-activating 0, it is confirmed whether or not the bit 7 is positioned at the corrected center point C ₁ . When this positioning is performed correctly, the correction work for the correction center point C ₁ is completed, so that the drilling is started in the accuracy correction range R ₁ . Then, the remaining modified center point _{C 2, C 3, C 4} , sequentially take corrective action similar positioning and above.

In this way, the corrected center points C ₁ , C ₂ ,
Highly accurate positioning is possible in the vicinity of C ₃ and C ₄ . Furthermore, if necessary, the number of correction center points is appropriately increased, and the above correction work is performed every time positioning is performed at each position, whereby mechanical play / play and members of the movable part of the punching machine are increased. Even if the flexure of is increased, the positioning can always be performed with high accuracy.

The present invention is not limited to the method of adjusting the bit position of the rock drill to the irradiation position of the laser beam LB. On the contrary, the laser beam LB may be aligned with the actual position of the bit 7. In this case, the operator collimates the laser beam LB by, for example, operating the automatic tracking type surveying instrument 40 by remote control of the correction means 60 so as to align the laser beam LB with the actual position of the bit 7. Adjust the direction. After the adjustment, the automatic tracking type survey instrument 40 automatically measures the irradiation position of the laser beam LB, and the measurement data is sent to the wireless communication device 41 and the wireless communication device 5.
