预制桩是建筑工程深基础工程常用桩型之一,由于具有承载力高、机具设备定型、施工操作不太复杂、可事先预制、施工速度快和造价相对不高等优点,得到较为广泛的应用。但预制桩的施工机具设备类型、工艺方法种类繁多,质量控制要求严格,怎样正确地选用施工机具、工艺方法和控制工程质量,对确保工程进度和降低工程成本,都具有十分重要
Prefabricated piles are one of the commonly used pile types in deep foundation engineering of construction projects. They have been widely used because of their advantages of high bearing capacity, machine equipment setting, less complex construction operations, pre-fabrication, high construction speed and relatively low cost. However, there are many kinds of construction equipment and process methods for prefabricated piles, and strict quality control requirements. How to correctly select construction equipment, process methods, and control project quality is very important for ensuring project progress and reducing project costs.
