摘要
在软土地基条件下,由于打桩流程、压机塌陷、基坑围护不到位、挖土顺序不正确等原因,很容易造成预应力混凝土管桩的倾斜。在综合考虑倾斜管桩的桩身质量及当地土质条件后,通过对预应力混凝土管桩采用顶推纠偏法进行处理,不仅大大降低了工程成本,而且加快了施工进度,具有良好的社会效益和经济效益。
Under the condition of soft soil foundation, it is easy to cause the inclination of pre-stressed concrete pipe pile, due to the pile driving process, pressing machine collapse, lacking of foundation pit support and incorrect excavation sequence. After the comprehensive consideration of the pile body quality of the slant pipe pile and the local soil conditions, the incremental launching rectification method has been used for the treatment of the prestressed concrete pipe pile, which not only greatly reduces the project cost, but also accelerates the construction progress, and has good social and economic benefits.
