What's the Difference Between Multi Functional Anchoring Drilling Rig and Percussive Drills?

The Multi Functional Anchoring Drilling Rig is a new high-efficiency rock drilling equipment designed for water conservancy, transportation engineering, and construction sites. It is widely used in slope stabilization, hydraulic engineering, road construction, open-pit mining, and geophysical exploration for drilling anchor holes or blast holes in various rock formations.

This rig serves fundamental engineering construction by performing anchor rod installation, dry powder/grout construction, engineering survey holes, and micropile drilling. It supports both down-the-hole hammer and drag bit drilling methods. The fully hydraulic rotary jet grouting rig, with its hydraulic drive and power head design, is suitable for vertical/inclined drilling and specialized grouting techniques (fixed/swirling/rotary jet piles). It excels in high-pressure grouting within Quaternary deposits like soil, sand, and gravel.

The Multi Functional Anchoring Drilling Rig offers customized solutions for marine geotechnical surveys, rock/soil anchoring support, and complex stratum drilling—demonstrating unique advantages in niche applications.

In contrast, percussive drills adapt to diverse geological conditions and are vital for cast-in-place pile foundations. They outperform other drills in gravel strata by compacting surrounding soil during drilling, enhancing hole stability and pile bearing capacity.

Modern percussive drills (e.g., CZ series) feature trailer-mounted components and use crank-link mechanisms to convert rotary motion into reciprocating movement. A hammer crushes rocks via free-fall impact, with cuttings removed by slurry or bailers.

Key distinctions:  

Multi Functional Anchoring Drilling Rig: Precision drilling for anchors/grouting; hydraulic efficiency; versatile in specialized engineering.

Percussive drills: Gravel-layer specialists; low efficiency (pulverizes rock); largely replaced in other strata due to high energy consumption and cross-bit limitations.
