e cleaning The drilling depth, diameter, location and shape of hole is directly related to the quality of pile and pile body black. Therefore, in addition to drilling process close 中英文資料 observation supervision, to meet the design requirements in drilling hole depth, with deep, hole, pore shape, pore size and other inspections. In the end hole inspection in full pliance with the design requirements, shall immediately proceed to bottom hole cleaning, avoid it too long that mud settling, caused by borehole collapse. For friction pile when the hole wall is easy to collapse, in underwater concrete perfusion before the sediment thickness of not more than 30cm。中英文資料 建筑工程灌注樁 中英文資料外文翻譯文獻(xiàn) Bored pile Summary Drill ( flushing, dig ) pile from the nieen 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. China39。s 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 highrise 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 bee hot issues in recent years. 中英文資料 The introduction of bored castinplace pile Perfusion pile refers to the construction site by mechanical drilling, steel pipe soil paction or human mining method in the foundation pile hole in form, and on its inner placed reinforcement cage, concrete made with different pile, drilling method, grouting pile can be divided again for castinplace pile, bored pile and digging several types of piles. Bored pile by pile into the definition and classification of a kind of pile. The characteristics of bored castinplace pile And sinking pile of hammering method, construction noise and vibration is smaller To construct than the precast pile of large diameter of pile In all kinds of ground can be used
