Problems solved by technology
Nowadays, when carrying out advanced geological drilling, the drilling is mainly carried out by manually controlling the horizontal drilling rig. However, due to the long length of the advanced geological drill pipe, the actual operation is inconvenient, and more manpower and material resources are required. The drilling efficiency is low and the labor intensity is low. Large, time-consuming and labor-intensive, and the drilling quality is not easy to guarantee

Abstract
The invention discloses an advanced geological drilling device. The advanced geological drilling device comprises a drilling rack arranged on the rear side of a tunnel face of a construction tunnel, a horizontal drilling machine arranged on the drilling rack, a horizontal drill rod arranged at the front end of the horizontal drilling machine, and a drill bit arranged at the front end of the horizontal drill rod, and the drilling rack is horizontally arranged. The drilling rack comprises two horizontal steel rails laid on the rear side of the tunnel face of the tunnel, a rear pushing frame moving front and back along the two horizontal steel rails, a rear limiting frame clamped on the two horizontal steel rails, a horizontal sliding frame horizontally sliding along the two horizontal steel rails, a hydraulic cylinder pushing the horizontal sliding frame to horizontally slide, and a front end supporting table located at the front ends of the two horizontal steel rails. An electronic circuit board is arranged in the front end supporting table and provided with a controller and a wireless communication module connected with the controller. The advanced geological drilling device is simple in structure, reasonable in design, low in input cost, easy and convenient to use and operate, good in using effect and capable of automatically finishing the drilling process of advanced geological drilled holes.
Description
technical field [0001] The invention relates to a drilling device, in particular to an advanced geological drilling device. Background technique [0002] Advanced geological prediction is to make advanced prediction of the surrounding rock and formation conditions in front of the tunnel face during tunnel excavation. There are many geophysical prospecting methods commonly used in advanced geological prediction, and mechanical drilling is a main method of advanced geological prediction. Mechanical drilling is to use advanced geological drill pipes to drill in several parts of the tunnel section, and determine the nature of the surrounding rock in front according to the rock and soil structure, structure and hydrogeology in the drill pipes. In actual mechanical drilling, three positions of the tunnel section are generally taken, namely the upper middle part, the left side and the right side of the tunnel section, and the surrounding rocks drilled out are compared and analyzed...
