静压(振动)沉管扩底灌注桩适用范围静压(振动)沉管扩底灌注桩适用范围大体上与夯扩桩或锤击振动沉管扩底桩相同。施工机械与设备静压沉管机在我国尚无标准设备,均是利用一般振动沉拔桩机加以改装而成。静压沉管扩底灌注桩是借助于桩架自重和配重通过卷扬机和滑轮组加压于桩管顶部,将桩管徐徐压入土中。桩架行走方式可以是滚管式,但多数为轨道式,以减少移动摩擦力。
Static pressure (vibration) Sinking Bottom Bored Piles Scope of application Static pressure (vibration) Sinking Bottom Bored Piles The scope of application is generally the same as that of a rammed-expanded pile or a hammer-vibrated immersed pipe. Construction machinery and equipment Static pressure pipe sinking machine in our country there is no standard equipment, are made using the general vibration sinking pile driver to be converted. Static pressure pipe expanded bottom pouring pile is by means of pile frame weight and weight by the hoist and pulley group pressurized at the top of the pile, the pile pipe slowly into the soil. Pile rack walking style can be rolled tube, but most of the track to reduce friction.
