Description

technical field [0001] The invention belongs to the technical field of advanced geological drilling, and in particular relates to a multifunctional 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. Through the comprehensive comparison and analysis of the surrounding rocks drilled in multiple hole positions, the surrounding rock conditions are recorded at a section every two...

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

In addition, when conducting advanced geological drilling nowadays, most of the advanced geological drilling holes are drilled one by one, and the manpower and material resources required to drill multiple drilling holes respectively are quite large, and the required construction period is long. Affected the progress of tunnel construction
