Development history of vibroflot in China

In China,the geotechnical engineering circle had know and noticed the application of vibroflotation technology abroad since the middle of 1970s. Especially after Tangshan Earthquake in 1976,China began emphasis the research on anti-seismic reinforcement technology of foundation and ground. In 1977, this method was widely spread, because of foundation of a large sum of industrial and civil buildings,and water conservation and traffic engineering. Until currently,China history of adopting vibroflotation technology in nearly 30years. And China has reached international advanced and top level in application mechanism, machinery equipment manufacture,construction process,especially in application scope and engineering difficulty etc. Vibroflotation foundation reinforcement technology has now been widely applied in water conservancy and hydropower, thermal power,petrochemical industry, highway traffic, port construction,and large-scale hydraulic fill foundation reinforcement projects in seaside areas. Especially in recent years, the project number and scale of China vibroflotation reinforcement projects has greatly increased. Ever since the year of 2000, China project amount of vibroflotation foundation reinforcement has in creased from nearly 1 million m3 per year to the current 10 million m3.

In 1977, the headquarter of BVEM,has successfully and independently researched and manufactured 30kW vibroflot, and has successfully applied it in the anti-seismic reinforcement project of the dam foundation composed of medium and fine grained loose sand, and beneath the main dam of Beijing Guanting Reservoir. In 1982, to meet the requirements of Three Gorges Project, China has organized research of 75kW vibroflot,and the achievements has successfully been applied in the dump filled weathered sand vibroflotation reinforcement project at 24-30m depth during Three Gorges second phase cofferdam.

Now the vibroflot equipments manufactured by BVEM has formed into a series of products with the power from 30kW to 260kW. The construction methods include the top feed vibroflotation and bottom feed vibroflotation.
