Multifunctional Climbing Drilling Rig: Equipped with Extended Drill Rods to Solve Deep‑hole Construction Challenges on Steep Slopes

In projects such as slope support, mine greening, highway mountain reinforcement, and anchor drilling prior to hydroseeding, steep rocky slopes have long posed major construction difficulties. Conventional drilling rigs feature limited climbing capacity. For deep‑hole operations, drill rods need to be repeatedly disassembled and connected, and the rig must be repositioned frequently. This consumes substantial labor and creates safety risks for high‑altitude work. Fitted with extended drill rods, the multifunctional climbing drilling rig addresses key pain points including difficult access to steep slopes, frequent rod connections and insufficient hole‑forming depth. It has become core construction equipment for mountain geotechnical engineering.

Traditional slope drilling is constrained by the travel of standard drill rods. For anchor bolt holes and grouting holes of moderate depth, drill rods have to be disassembled and connected multiple times. On steep, uneven slopes covered with broken stones, each rod connection requires shutdown and position adjustment of the rig. This not only delays the overall construction schedule, but also causes wear and misalignment of threaded joints during assembly and disassembly, resulting in borehole deviation and inconsistent hole‑forming quality. In addition, moving the whole rig on steep slopes carries high risks such as slipping and sliding. When workers operate on cliff faces, they are exposed to prominent rock‑fall hazards.

Built on a specialized climbing chassis, the multifunctional climbing drilling rigadapts to all kinds of rocky and soil‑rock mixed slopes ranging from 0° to 90°. With the help of traction devices, it can get into position on steep rock faces. There is no need for extensive scaffold erection or large‑scale renovation of working surfaces; the equipment can reach work points directly. The extended telescopic drill rod greatly increases single‑drilling travel. Short anchor bolt holes can be completed in one drilling pass, drastically cutting down rod assembly‑disassembly cycles, reducing wear on threaded joints and shortening downtime. Equipped with a long guide structure, the rig delivers superior drilling stability, effectively guaranteeing borehole straightness, producing well‑formed holes and mitigating hole collapse and deviation for consistent and reliable hole‑forming quality. For steep‑slope work, fewer rod‑connection procedures mean fewer repositioning movements of the entire rig. Less equipment relocation on hazardous slopes further boosts construction safety and working efficiency.

Catering to the growing demand for deep‑hole and steep‑slope construction in mountain‑based projects, the multifunctional climbing drilling rig with extended drill rods combines equipment traversing capability and drilling depth. Balancing safety, efficiency and hole‑forming quality, it offers a reliable drilling solution for complex mountain engineering.
