Rapid impact compaction has a history of thousands of years in China. According to records, China used impact compaction when building the Great Wall. The Chinese rely on strength to lift heavy stones and smash them to the ground to achieve the purpose of compacting the soil. The filling section of Qinzhi Road, China's first expressway dating back 2000 years, is rammed earth. Therefore, China has a long history of shock compaction, and today's rapid shock compaction is a continuation of ancient Chinese shock compaction.

The Birth of Rapid Impact Compaction in China

At first, people relied on manpower to lift the heavy blocks and smash them to the ground to achieve the purpose of compacting the soil. Later, through the development, the use of tripods was used to lift the heavier blocks to a higher height for soil compaction. Since the emergence of lifting equipment, the mass and lifting height of the heavy block have been further increased, which is called "dynamic compaction".

At the end of the last century, impact rollers combined with ramming and rolling were popularized on a large scale, and some other forms of compaction equipment such as drum rollers, vibratory rollers, frog compactors and vibratory plate compactors were widely used in the market. 

At the end of the last century, shock compaction technology was widely used in China, but its operation blind area was large and the damage to adjacent structures was large. Yang Shiji, a researcher from the Highway Science Research Institute of the Ministry of Transport, noticed the defects of impact compaction, and took the lead in proposing the need for a high-strength, high-efficiency compaction equipment that can be matched with impact rollers, and can be close to the construction of sensitive structures. 

In 2003, China Rapid Impact Compactor was born in Tai'an, Shandong. The inventor, Cao Bin, is now a senior engineer of "夯神" .

Development of Rapid Impact Compaction in China

China's first rapid impact compactor has been tested by the Testing Center of the Ministry of Transport of China, and combined with China's Gansu, Anhui, Guangdong and other cities to carry out experimental research on the application effect of rapid impact compaction on expressways. The project "Research on Hydraulic Compactor and Its Application" passed the technical appraisal organized by the Beijing Municipal Science and Technology Commission, and the conclusion was the first in China and reached the international advanced level.

The first-generation rapid impact compactor was verified by the multi-segment test organized and implemented by researcher Yang Shiji, and tested by the Xi'an Road Construction Machinery Testing Center of the Ministry of Communications. In January 2004, it passed the ministerial and provincial appraisal in Beijing. In that year, it was fully promoted and applied in the Meihe Expressway in Guangdong. After the rapid impact compaction equipment has been successfully developed, it has successfully defeated the world brand rapid impact compaction equipment in the Chinese road construction market with outstanding features such as high efficiency and high mobility.

With the feedback of the problems in use, the hydraulic hammer designed by Cao Bin is a rapid impact compactor when the plate is installed at the bottom, and a hydraulic pile hammer when the pile cap is installed at the bottom, and the first-generation high-speed hydraulic compactor is upgraded.

The third generation of rapid impact compaction equipment has improved on the basis of the second generation, in terms of ramming strength (impact depth), productivity and reliability during continuous work, ease of operation and transition safety, manufacturing. Major breakthroughs have been made in technology and other aspects.

The strength of the third-generation rapid impact compaction machine is improved, the impact depth of roadbed reinforcement is more than 4 meters, and the actual measurement of a road is 4.5 meters; in addition, the tamping frequency is increased to more than 30 blows per minute, and the productivity is greatly improved; due to The liquid flow resistance is small, and there is no overheating phenomenon when working continuously for a long time. As long as the supporting loader has no defects, it can work continuously for 24 hours.

Now, China's "夯神" rapid impact compaction equipment has been updated to the sixth generation!
