Construction method of rapid impact compaction for loader - construction in rapid impact compactor workshop building

About This

The construction method of hydraulic ramming of loaders. Rapid impact compaction machines are constructed in workshop buildings. Rapid impact compactors can eliminate or weaken the inherent defects and man-made defects of layered rolling roadbed, and eliminate the possible post-construction settlement during the foundation use period in advance, and solve the problem. The problems of different settlements at the junction of bridge head jumping, old and new subgrade and subgrade filling and excavation in my country. The short-term development history and rapid popularization and use are precisely to meet the high standards and high requirements of the current highway infrastructure construction, which also makes the hydraulic subgrade compactor not well known to most construction passers-by. 

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.

RIC Model Excavator Requirements

• HC42: 42 kJ impact energy, 3,500 kg drop weight, 1.2-2.5m depth, for 30t excavators
• HC150: 150 kJ impact energy, 10,000 kg drop weight, 4-8m depth, for 45-55t excavators
• HC180: 180 kJ impact energy, 12,000 kg drop weight, 4-8m depth, for 55-70t excavators
• HC240: 240 kJ impact energy, 16,000 kg drop weight, 5-9m depth, for 70t+ excavators
