桩板式无土路基桩基础施工技术

Construction Technology of Pile Foundation of Pile-Plate Type Soilless Subgrade

公路工程拓宽处理过程中,需要占用的资源较多,并存在拓宽路基与旧路基的咬合等问题。在这样的发展形势下,桩板式无土路基以其特有的优势,受到了业界的关注。基于此,论文结合应用于某一级公路的新型结构桩板式无土路基的施工,对其中的管桩沉桩施工技术进行总结,阐述施工过程中的关键控制要点。

In the process of highway widening projects,resources need to be occupied,and there are some problems such as the occlusal between the widening roadbed and the old roadbed.Under such a development situation,pile-slab soilless roadbed has been paid attention to by the industry for its unique advantages.Based on this,combined with the construction of the new structure pile-plate soilless roadbed applied to a first class highway,this paper summarizes the construction technology of pipe pile driving,and expounds the key control points in the construction process.
