振动打桩锤在施工时产生较大的噪声和振动,形成公害,特别是在城市人口和建筑密集区,使用受到了限制。另外,用起重机起吊振动锤拔桩时,除了桩的抗拔阻力之外,振动器的振动也不可避免地传到起重机的吊臂上引起疲劳。特别值得注意的是在打拔桩作业时,从切断振动器的电源开关到停 Vibratory hammers generate large noise and vibration during construction, causing public hazards, especially in the urban population and construction-intensive areas, where use is limited. In addition, when a vibratory hammer is used to lift a pile by using a crane, in addition to the pull-out resistance of the pile, vibration of the vibrator is inevitably transmitted to the boom of the crane to cause fatigue. It is particularly noteworthy that the power switch of the vibrator is switched off and stopped when pulling the pile.
