煤炭建筑施工单位在应用夯扩桩技术中的探索与发展

桩基础在建筑工程建设中应用相当广泛。高层建筑和多层工业厂房越来越多,建筑物的荷载也越来越重。夯扩桩是在沉管式混凝土灌注桩施工基础上发展起来的一种新型桩基础,它比预制钢筋混凝土桩节省大量钢材和工程造价,与钻孔灌注桩和沉管式混凝土灌注桩相比又具有桩基承载能力高和桩基施工质量好等优点。

Exploration and Development of Ramming Expansion Pile Technology Application in Coal Construcion

Pile foundation is widely used in the construction.With high-rise buildings and muti-floor industrial building are more and more,the load of building is also more and more heavy,ramming expansion pile is a king foundation developed on the basis of the sunken tube concrete pile,it saves great amount of steel and cost than precast tube concrete pile,compared with drilling concrete pile and sunken tube concrete plie has advantages of high pile foundation bearing capacity and good pile foundation construction quality.
