Study On The Construction Techniques Of Vibroflotation Bottom Feed

There are almost 30 years since China introduced the vibroflotation techniques, by the 30 years'development, vibroflotation techniques are applied in many areas in China such as waterpower, thermal power, highroad, railroad, petrochemical industry and civil constructions and etc. Presently our country's vibroflotation techniques to deal with the mechanism, the machines'making, the construction technics and its scope and complexity have all achieved the international top level. But along with the requirement of our littoral provinces need more fill-sea projects and our west-south provinces need cosmically water power constructions increased, domestic machines'power,techniques and applicability in existence cannot satisfy the needs. The research of the vibroflotation bottom feed that this paper referred to is one branch subject of nation"the eleventh-five years"project of vibroflotation that our company has declared and would undertake, its primary content is to research the vibroflotation support techniques used in soft aggraded silt soft geological foundation of littoral or inland lakes provinces. Now the subject has already finished the machines and the technics research, The theory has been applied to some typical projects and acquired better effect.The authors of this paper are of the main subject research personnel, the paper primarily summarized the research of the vibroflotation bottom feed, the technics, the key techniques used in practice and the achievement of the projects, also the authors makes the quantificational academic analyses with the mechanism and the support principles.The lower discharge vibroflocation machines and techniques are first in the area of our domestic geological foundation support. In practice, the lower discharge vibroflocation techniques can be applied to deal with the depth of 22m soil, in the highest flight of the world. Especially, The lower discharge vibroflocation system and the techniques such as multi-branches water-air system and pressurize bore/ compression techniques that developed by our company are very different from the...
