The Practical Application And Environmental Management On The Construction Phase Of The Down-hole Dynamic Compaction Technology

With China’s economic development and urban construction continues to expandthe scale of urban land resource is nervous, has become the main bottleneck of theurban construction and development in our country. City landfill occupied around thecity a lot of land, with urban development zone by the center to spread out around, a lotof new buildings need in the suburbs of the city building miscellaneous fill landfill soil.Miscellaneous fill in the landfill soil foundation cannot satisfy the requirement ofbuilding foundation bearing capacity, and their own, there is still a settlement, oftencan’t directly as construction of foundation use. At the same time, the engineeringconstruction project has the material consumption, and construction activities, theenvironmental pollution caused by very serious characteristics, construction with theenvironmental pollution and ecological destruction.This paper through the actual case study in high fill the garbage ground treatment.By the use of the construction waste DDC technology pile composite foundation,formulate and refined DDC pile compacting hole-backfilling ramming into-test theconstruction methods, establish and perfect the construction quality assurance system,strictly according to the engineering construction quality control measures construction.Test results show DDC relevant national standards with pile technology standards,procedures, and meet the design requirements, and has a broad prospect of application.DDC pile in the construction phase of environmental management measuresthrough effective identification and evaluation of environmental factors, an analysis ofthe technology in the construction process on the surrounding environment may cause pollution, the environmental impact of the major factors that put forward a detailedcontrol measures. By Establishing the environmental management system, strictenvironmental management of construction site, strict control of noise, dust, wastewater, exhaust and other pollution. Proposed to carry out the "6-20" environmentalmanagement activities in DDC technology process. The6stages means constructionorganization and planning, construction site investigation, construction programselection, construction process management, post-construction environmentalmanagement, construction Summary. The6stages contains20environmentalsupervision activities, to Implementation green construction in the whole process,achieve the goal of cleaner production.From the technical and economic, environmental benefits, and other aspects ofsocial impact analysis, comparison, DDC has a high economic efficiency of pileconstruction, the smaller the environmental impact, and thus has good social andpromotion...
