目前在钻孔桩施工中普遍采用吊斗法灌注砼 ,其突出的问题是漏斗容积小 ,吊斗受漏斗所限 ,一般做得也较小 ,其盛料量一般≯ 1 0ｍ3。在灌注过程中 ,吊装一次砼 ,其灌注冲击力相应较小 ,每斗的灌注时间短 ,对孔内砼来说“静”的时间大于“动”的时间 ,将给连续灌注带来一定的困维 Currently in the construction of bored piles commonly used method of pouring concrete pouring bucket, the outstanding problem is that the funnel volume is small, hopper limited by the funnel, the general is also done smaller, the Sheng material volume is generally ≯ 10m3. In the process of perfusion, hoisting a concrete, the perfusion impact force is smaller, each bucket of perfusion time is short, on the hole concrete “static” time is greater than “moving” time, will give a continuous infusion of certain Sleepy dimension
