Problems solved by technology

In the actual drilling, due to the long length of the advanced geological drill pipe, the actual operation is inconvenient, more manpower and material resources are required, the drilling efficiency is low, the labor intensity is high, and time-consuming and labor-intensive. The manpower and material resources are quite large, and the required construction period is long, which greatly affects the progress of the tunnel construction.

Abstract

The invention discloses an advance borehole frame based on an adjustable triangular support. The advance borehole frame comprises a horizontal workbench, two horizontal steel rails and a drilling rig installation rack moving back and forth along the two horizontal steel rails. The drilling rig installation rack comprises a rectangular support clamped between the two horizontal steel rails, a vertical installation rack arranged above the middle part of the rectangular support, two oblique connecting rods installed on the left and right sides above the rectangular support and two horizontal sliding seats moving left and right along the upper part of the rectangular support. The rectangular support, the vertical support plate, the two oblique connecting rods and the two horizontal sliding seats are formed to be an adjustable rectangular support. Three horizontal drilling rigs are installed at three vertexes of the adjustable rectangular support.The advance borehole frame based on the adjustable triangular support has following beneficial effects: the advance borehole frame is simple in structure, reasonable in design, low in investment cost, easy and convenient in operation and fine in usage effect; drilling processes of three geological boreholes can be synchronously finished; and positions of three advance boreholes can be adjusted easily and conveniently.

Description

technical field [0001] The invention belongs to the technical field of advanced geological drilling, and in particular relates to an advanced drilling frame based on an adjustable triangular support. 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 tun...
