Abstract


Prestressed Concrete Piles is tensioned using the first centrifugal molding process and the legal system into a hollow body slender precast concrete , is a standardized , industrialized , high performance components. Compared with steel pipe piles , prestressed concrete piles by soil penetration is not strong, piling pile can not be subjected to greater stress and other shortcomings hammering restrictions currently in the upper part of the load is large, deep pile design engineering projects, concrete pipe application subject to certain restrictions . However, because of prestressed concrete pipe pile foundation has excellent stress characteristics and advantages of low construction cost will be applied to a pile of large industrial and civil engineering research and development trends. In this paper, domestic and foreign research results, elaborated fine , long, deep concrete piles PHC Baosteel stainless steel works in the successful use . The main contents of this paper are as follows : ① status quo based on the use of precast piles , systematically expounded the principle of prefabricated pile construction technology and quality control measures. ② pile of Baosteel Stainless Steel Engineering design process , for example, selected from stratum , pile type selection, pile length determined pile exception handling , etc., its design principles and design a comprehensive analysis . Discusses the pile tip reinforcement structure and the significance of the pile head , pile tip structure introduced improved methods and reinforced trailer coupling process . ③ discusses the construction of Stainless Steel pile the whole process . Shen pile body proposed to ensure integrity and control plane displacement pile top technical measures introduced ultra-deep pile to send to send Pile on improved method . Finally the results were analyzed on the construction . ④ describes the construction of a large pile group density of the surrounding building ( structure) deformation hazards presented for large density deformation monitoring group pile construction methods and technical measures to prevent deformation damage . The results showed that: the upper load prestressed concrete piles used in large deep pile design of large-scale industrial and civil buildings is feasible ; through monitoring, to take reasonable technical measures can effectively prevent the construction of large density of pile groups built on the surrounding ( structures) deformation hazards.
