Problems solved by technology

This method has a large amount of ineffective drilling, scattered survey holes, and cannot fully and truly reflect the geological information of the surrounding rock of the tunnel; in addition, in areas with harsh geological conditions such as perennial snow and high altitude, equipment transportation, water supply, power supply, etc. It is severely restricted, it is difficult to implement, and the overall cost is high. Therefore, it is urgent to develop a drilling rig that is efficient, convenient, and capable of long-distance horizontal directional coring

Abstract

A horizontal coring drilling machine comprises a drilling frame, a chassis is hinged to the lower portion of the drilling frame, supporting legs are arranged on the chassis, a power head assembly, a machine cover, a drilling rod, a cab and a vice are sequentially arranged above the drilling frame, and a drilling rod assembling and disassembling device is arranged on the side face of the drilling frame. The horizontal coring drilling machine does not need to penetrate through a useless rock layer on the upper portion of a mountain, directional linear exploration can be directly conducted along the horizontal axis of a tunnel, the invalid footage amount is greatly reduced, the comprehensive efficiency is high, and the drilling machine is provided with an independent walking system, convenient to transition and low in engineering cost.

Description

technical field [0001] The invention relates to the technical field of coring for tunnel construction, in particular to a horizontal core drilling machine. Background technique [0002] In recent years, under the stimulation of favorable policies, the construction of underground space projects such as highways and railway tunnels in my country has increased year by year. However, detailed and accurate geological data are needed to support the route planning and construction scheme of tunnel engineering. In terms of tunnel construction, the traditional geological exploration method is to arrange at intervals, vertically cross the upper overburden, drill to the tunnel axis, and use discrete sampling methods to obtain the characteristics of the surrounding rock of the tunnel axis. This method has a large amount of ineffective drilling, scattered survey holes, and cannot fully and truly reflect the geological information of the surrounding rock of the tunnel; in addition, in ar...
