振动、夯打沉管灌注桩在软土地基的应用

Use of Vibrating and Ramming Sinking Pipe Perfusion Pile for Mollescent Subgrade

采用沉管灌注桩法处理软土地基 ,经试桩并确定单桩承载力后 ,采用单打法进行施工。实践证明 ,采用振动、夯打沉管灌桩法处理软土地基 ,具有施工简单、工期短、节约材料、经济效益好。

To adopt sinking pipe perfusion pile method processes mollescent subgrade .After testing pile and determining the load bearing capacity of single pile,the single piling method is adopted for construction.The practice has proved that to adopt vibrating and ramming sinking pipe perfusion pile method for processing mollescent subgrade possesses the characters of construction being simple,the time limit for a project being short,the materials being saving,the economic profit being good,the requirements to project structure being assurable and the damage of construction machines being little,etc.
