建筑工程灌注桩 中英文资料外文翻译文献 Bored pile Summary Drill ( flushing, dig ) pile from the nineteen sixties, beginning in Henan province Nanyang region since the development application, because of its many advantages, has been widely used in soft soil, loess, including soil, expansive soil and other special types of foundation and industrial, civil, municipal, railway, highway, port and other types of Engineering practice. And precast pile, bored pile construction of no noise, no vibration, on the surrounding buildings and small environmental impact, pile diameter, buried deep, large bearing capacity. Chinas drilling pile maximum diameter of pile has reached 4000mm, maximum deep pile has reached 104m, and the steel pipe pile maximum diameter of 1200mm, the largest pile of prestressed concrete pipe pile with deep 83m, maximum diameter of 1300mm, the biggest pile depth 40m. Along with our country socialist construction is booming, with high-rise buildings, large span bridges on the rise, the bearing capacity of pile foundation with higher requirements. Large diameter bored pile therefore gets rapid development, pile length and pile diameter also do bigger more. However, in the existing various methods of pile, bored pile has many advantages and is widely used in construction, but it is hard to avoid the impact of mud, which not only reduces the bearing capacity of pile expectations, but also caused a serious waste of materials. Manual hole digging pile is difficult to achieve greater depth, its bearing capacity is also difficult to just as one wishes. In view of bored pile in this situation, how to improve the pile construction technology level, make the input material to be more reasonable to use, so as to greatly increase the bearing capacity of single pile in engineering field, have become hot issues in recent years. The introduction of bored cast-in-place pile Perfusion pile refers to the construction site by mechanical drilling, steel pipe soil compaction or huma
