What's the best method for compacting fill? - HENGDA RIC

About This

Rapid Impact Compaction Technology Overview

• High-frequency, controlled energy compaction technique
• Effective depth: typically 1-9 meters
• Impact rate: 30-80 blows per minute
• Drop weight: 1.2 to 20 tonnes (depending on model)
• Foot diameter: 560 MM to 2000 MM
• In 2003, Cao Bin, Chief Engineer of Taian Hengda Machinery Co., Ltd., independently developed Rapid Impact Compaction (RIC) technology in China.
