Embodiment 1

[0023] As introduced in the background technology, in the construction of tunnel blasting and excavation, it often takes a lot of time and money to repeatedly locate the drilling position. The accuracy directly affects the blasting effect, and it is easy to cause problems such as over-excavation and under-excavation. In order to solve the above technical problems, this application proposes the following figure 1 The shown device for realizing precise laser positioning of the tunnel drilling position includes a laser box 1 and a laser box fixing device 2, and the laser box fixing device 2 is provided with a parallel laser line chute 5 and a laser point chute 6. The laser line chute 5 is provided with three laser line emitters 3, the laser point chute 6 is provided with three laser point emitters 4, the laser line chute 5 and the laser point chute 6 is provided with a sliding hole along the groove, the laser line transmitter 3 and the laser point transmitter 4 are respectively c...

Embodiment 2

[0026] This embodiment is refined on the basis of the above embodiments, that is, figure 1 As shown, the supporting device includes a round rod 7 , a sleeve 8 and a base 10 , one end of the round rod 7 is placed in the sleeve 8 and connected with the sleeve 8 through a positioning bolt 9 . During the telescopic adjustment, after the adjustment is completed, the round rod 7 and the sleeve 8 are fixed by the positioning bolts.

Embodiment 3

[0028] This embodiment adopts a support device structure different from that of Embodiment 2 on the basis of Embodiment 1, such as Figure 4 As shown, the supporting device includes an outer cylinder 21, an upper rod 22, a lower rod 23 and a base 10, the bottom of the lower rod is fixed on the base, one end of the upper rod 22 and the lower rod 23 are respectively placed in the outer cylinder 21 and the upper rod 22 1. The lower rod 23 is connected to the outer cylinder 21 by threads, and the directions of the threads on the upper rod 22 and the lower rod 23 are opposite. When adjusting the height, fix the base with your feet, hold the upper rod with one hand, and turn the outer cylinder with the other hand to achieve height adjustment. Adopting this structure, the adjustable precision of its height is high.

Abstract

The invention discloses a device for realizing laser precise positioning of a tunnel drilling position and a construction method. The device comprises a laser box and a laser box fixing device, and the laser box fixing device is provided with parallel laser line sliding groove and laser point sliding groove. Three laser line emitters are arranged in the laser line sliding groove, and three laser point emitters are arranged in the laser point sliding groove. The laser line sliding groove and the laser point sliding groove are provided with sliding holes along the grooves, and the laser line emitters and the laser point emitters are correspondingly connected with moving rods. One ends of the moving rods are placed outside the sliding holes, the laser box fixing device is fixed to a telescopic supporting device, and the telescopic direction of the laser line sliding groove and the laser point sliding groove are perpendicular to the telescopic direction of the supporting device. The laserpoint emitters and the laser line emitters are adopted, the position of laser can be adjusted according to the use conditions, the laser can illuminate the tunnel environment, and the construction isfacilitated for personnel; and the precision of laser point positioning can be adjusted to ensure that the laser accurately coincides with the drilling position.

Description

technical field [0001] The invention relates to the field of tunnel construction devices, in particular to a device and a construction method for realizing precise laser positioning of tunnel drilling positions. Background technique [0002] In the tunnel blasting and excavation construction, due to factors such as dim light in the tunnel and poor construction environment, it is a difficult problem to determine the location of the tunnel drilling and its efficient construction. It often takes a lot of time and money to repeatedly locate the drilling location. Especially when blasting methods such as tunnel drilling and blasting excavation technology are used during construction, the accuracy of the drilling position directly affects the blasting effect, which is likely to cause problems such as over-excavation and under-excavation, resulting in additional costs during construction. It takes time and money to deal with the deviation of the blasting effect, and the accuracy of...
