step two: moving the line laser 3 of the arc-shaped arch frame 1 and the linear frame 2 corresponding to the tunnel processing point 7 at the position of the tunnel 4;
step three: the line laser 3 emits laser lines, the arc arch 1 and the line laser 3 of the straight line frame 2 emit laser lines which are crossed to form a grid, and the cross point of the grid is a tunnel processing point 7.
Through the technical scheme, the line lasers 3 are transversely and longitudinally arranged, so that the lines emitted by the transverse and longitudinal line lasers 3 are positioned in a crossed manner, and the position of the tunnel processing point 7 is positioned. The tunnel processing points 7 of the tunnel 4 are usually arranged at regular intervals, and the simultaneous positioning of the plurality of tunnel processing points 7 can be realized by a plurality of line lasers 3.
In general, in the tunnel construction, it is necessary to perform the bridging measurement to confirm the positions of the tunnel processing points 7 on the inner side, and the measurement error is large, so that the confirmation of the positions between the tunnel processing points 7 is easily deviated by the previous tunnel processing point 7. Therefore, in this embodiment, the position of the tunneling processing point 7 is simulated by the computer, and it is confirmed that the tunneling processing point 7 is located at the position of the tunnel 4 corresponding to the cross section, and the angle of the tunneling processing point 7 with respect to the center point of the cross section of the tunnel 4, which are all parameters, can be confirmed.
