Problems solved by technology
Traditional slope anchor construction often requires the erection of steel pipe supports, which will cause safety problems in production. On the other hand, erecting support and drilling construction of slope anchors has a long construction period and low work efficiency. The inclination angle of the drilling is not easy to control and is often ignored.

Embodiment 1
[0021] see figure 1 , a new construction method of slope protection bolt high-efficiency drilling of the present embodiment, the steps are:
[0022] Step 1: The site of the area where the machine will be drilled is initially leveled, and the new rock bolter can drive, enter and exit, and operate;
[0023] Step 2: Use the CNC system of the drilling rig, wait for the drilling rig to walk to the drilling area by itself, and raise the drilling machine to the height of the bolt hole through the CNC system and the lifting system according to the point set by the surveyor;
[0024] Step 3: The drilling rig uses the angle adjustment system at the drill bit to drill holes according to the inclination angle specified in the design drawings, and sets the drilling depth in advance through the data transmission system before drilling;
[0025] Step 4: After the hole is formed, blow it out and clear the hole in time, manually fix the anchor rod at the drill bit on the self-contained operat...

The invention discloses a novel construction method for efficient drilling of a slope protection anchor rod, and belongs to the technical field of slope construction. The method comprises the steps that firstly, the site of a to-be-drilled area is primarily leveled through a machine, and the novel anchor rod drilling machine can run, go in and out and operate; 2, a drilling machine is provided with a numerical control system, and after the drilling machine walks to a drilling area by itself, the drilling machine is lifted to the height of an anchor rod hole position through the numerical control system and a lifting system according to point positions formulated by measuring personnel; 3, the drilling machine drills according to the inclination angle formulated by the design drawing through a drill bit angle adjusting system, and the drilling depth is set in advance through a data transmission system before drilling; fourthly, after the hole is formed, the hole is blown away and cleaned in time, the anchor rod is manually fixed to a drill bit on a self-carried operation platform, the anchor rod is fed into the formed anchor rod hole through a drilling machine, and a certain length is reserved outside the hole. The anchor rod drilling and hole forming efficiency and the accuracy of the hole forming angle are greatly improved, and the safety problem existing in traditional erection support construction is solved.
Description
technical field [0001] The invention relates to the technical field of slope construction, and more specifically relates to a construction method for high-efficiency drilling of novel slope protection bolts. Background technique [0002] At present, the construction technology and construction quality of road embankment slope in my country have been greatly improved. Traditional slope anchor construction often requires the erection of steel pipe supports, which will cause safety problems in production. On the other hand, erecting support and drilling construction of slope anchors has a long construction period and low work efficiency. The inclination angle of the drilling is not easy to control and is often ignored. . Contents of the invention [0003] 1. Problems to be solved [0004] Aiming at the defects and deficiencies of the existing technology, the present invention provides a new construction method for high-efficiency drilling of slope protection anchor rods.
