Study On Rotary Drilling Pile Construction And Detection Methods Of Management

Rotary drilling pile method is a new construction method of bored piles, the use of rotarydrilling rig and integration of the new technology, modern hydraulic machinery, can adapt tothe construction of clay, sand, gravel layer and in slightly weathered rock geologicalconditions. After the Second World War, rotary drilling pile method in Europe,70to80yearsof rapid development in Japan, the90’s of the last century was introduced into China in recentyears, just try to use.In this paper, through the pile project of a specific project, around the rotary drillingmethod construction and testing management, the use of social survey, field practice thanother methods, based on the analysis of the construction and testing management. This paperfirstly introduces the project overview of a pile, engineering condition, environment etc..Followed by analysis of superiority of the mechanical characteristics of rotary machine, themain system, and the rotary drilling in similar engineering cases at home and abroad and theproject to compare, and draws the preliminary conclusion of rotary drilling pile method isfeasible. Then, from the auger type selection, brand selection, bit selection, dry excavationmethod selected, select the appropriate equipment and construction method for pileconstruction. Then carries on the construction organization design, especially equipmentorganization, personnel organization, organization, construction technology, found theproblem processing and other aspects of organization design. At the end of the detectionmethod, detection technologies are introduced.The main research contents of this paper, from the practical engineering, used inengineering practice, practical in engineering field. Therefore, research construct ion anddetection management of rotary drilling pile method, can conduct, practical and universalsignificance, dug pile engineering for other rotary, especially for rotary drilling pile methodselection, rotary drilling pile construction organization design, quality testing, as a reference.
