Multi-pipe Drilling Rig

Multi-pipe Drilling Rig
Our multi-pipe drilling rig is a kind of drilling equipment. It is widely used for excavation support wall, cut off wall and ground reinforcement. Besides, it also can be used as oil drilling equipment, gas drilling equipment, and well drilling equipment. Our multi-pipe drilling rig can be divided into three categories according to the diameters: Ф650, Ф850 and Ф1000.

Working Principles of Multi-pipe Drilling Rig
Our multi-pipe drilling rig adopts SMW methods. Two types of SMW methods are available. The first one is to mix and agitate soil and cement slurry in the original position to form underground diaphragm wall. The second one is to insert core materials into cement agitation body.

Advantages of Multi-pipe Drilling Rig
1. Higher cutoff performance
2. Lower impact on the surrounding ground
3. Shorter construction period
4. Multi-application
5. No vibration and low noise
6. Less spoils
7. Less wall strength is required

Application of Multi-pipe Drilling Rig
It's widely applied to the following fields.

Excavation support wall
Cut off wall
Ground reinforcement

Applicable soil of Multi-pipe Drilling Rig
Our multi-pipe drilling rig has wide applicability to all sorts of soil whose standard penetration value is less than 50, like clay, powder soil and strong weathered rock.

Construction Procedure
When SMW drilling rig drills, cement slurry is poured into the left and right drilling pipes and compression air is injected into the middle drilling.
