zc-3型振动锤是振动冲击沉管灌注桩的主要施工机械。图1是ZC-3型振动锤的照片,图2是装在吊车上施工的照片。其特点是具有冲击和振动双重作用,且冲击力比其振动力大十倍左右,因而桩管下沉的穿透力强,桩管能顺利进入砂卵石层,使桩尖支承在较坚硬的地基土上。比之纯振动的振动 The zc-3 ​​vibratory hammer is the main construction machinery for vibratory impact sinking cast-in-place piles. Figure 1 is a photograph of the ZC-3 vibratory hammer and Figure 2 is a photograph of the construction carried on a crane. Its characteristic is that it has the dual functions of impact and vibration, and the impact force is about ten times larger than its vibratory force. Therefore, the penetrating ability of the pile pipe is strong, the pile pipe can smoothly enter the sand and gravel layer, and the pile tip is supported on the harder one. Ground soil. Compared to pure vibration
