Vibrator Type Applications Explained
This solution clarifies the matching between vibrator types (Group I) and their construction applications (Group II).
Needle Vibrator (P) Applications
Matches with: 3. Beam-Column Junction
Ideal for internal compaction in narrow, heavily reinforced areas like beam-column junctions.
Shutter Vibrator (Q) Applications
Matches with: 4. Retaining Wall
Used externally on formwork (shutters), effective for consolidating concrete in walls, including retaining walls.
Surface Vibrator (R) Applications
Matches with: 1. Concrete Pavement
Designed for external vibration on the concrete surface, suitable for slabs and pavements.
Table Vibrator (S) Applications
Matches with: 2. Pre-cast Concrete Unit
Utilized for pre-cast elements; vibrates moulds placed on a table for uniform compaction.
