Technical Field

The invention relates to the technical field of railway engineering investigation, in particular to a multi-angle full-hydraulic portable drilling machine for railway engineering investigation.

Background

With the continuous development of traffic technology, the country invests hundreds of thousands of high-grade roads and railways every year. High-grade roads and railways are built in mountainous heavy hill areas, and a tunnel excavation mode is usually adopted in order to shorten mileage, improve line shape and protect environment.

In the railway tunnel construction process, because the front geological condition is unknown, some unfavorable geological factors (such as faults, broken zones, karst caves, underground rivers and the like) are often encountered. These geological factors not only affect the tunneling speed of the tunnel, but also cause serious engineering accidents (such as collapse, debris flow, heavy water gushing and the like). Therefore, the advance geological survey of the tunnel is required before the tunnel is excavated.

The advanced geological forecast is to forecast the surrounding rock and stratum conditions in front of the tunnel face (for example, forecast whether a fault, a broken zone, a karst cave and other unfavorable geological structures exist in front of the tunnel) during tunnel excavation. There are many geophysical prospecting methods commonly used for advance geological prediction, and mechanical drilling is a main advance geological prediction method. Mechanical drilling is to drill at a plurality of parts of a tunnel section by using an advanced geological drill rod, and the property of the surrounding rock in front is judged according to the geotechnical structure, structure and hydrogeology in the drill rod. In practice, when mechanical drilling is performed, generally, three position points of a tunnel section are taken, the three positions of the middle upper part, the left side and the right side of the tunnel section are respectively taken, the drilled surrounding rocks are comprehensively contrasted and analyzed, and then the surrounding rock conditions are recorded according to one section per two meters.

At present, a drilling machine for drilling and coring in the advanced geology of a tunnel in the prior art occupies a large area and can only realize drilling in the horizontal direction; it has poor flexibility;

therefore, a multi-angle full-hydraulic portable drilling machine for railway engineering investigation, which has the advantages of simple structure, simplicity and convenience in operation and multi-angle adjustment, is urgently needed.
