振动沉管桩是灌注桩的一种，一般直径为300～450毫米，它具有成桩速度快，施工工艺简单，钻孔圆度好，超径系数小，节省材料，成桩质量高等优点，故此在许多地方已得到广泛应用．振动沉管桩主要适用于松软层，深度不超过25米的电站厂房和楼房的基础施工．它的施工过程如下；在 Vibrating immersed pipe piles are one kind of cast-in-place piles, generally 300 to 450 mm in diameter. They have the advantages of quick pile forming, simple construction process, good roundness of drilling, low coefficient of super-diameter, material saving, and high pile quality. Therefore, it has been widely used in many places. Vibrating immersed pipe piles are mainly used for the foundation construction of power plant buildings and buildings whose depth does not exceed 25 meters. Its construction process is as follows;
