预应力混凝土管桩施工技术在施工中的应用

Application of Construction Technology of Prestressed Concrete Pipe Pile in Construction

济南机场扩建工程工作区综合保障楼项目基础工程施工中,桩基础类型是预应力混凝土管桩。在施工前做好压桩机机型选择,并验收成品桩。施工过程中送桩、沉桩、接桩都有相应的技术措施。预应力混凝土管桩的特点是单桩承载力高、质量好、施工快、文明施工好、综合效益好等。这些特点在本工程都有所体现。

During the foundation construction of the comprehensive support building project in the work area of Ji'nan Airport Expansion Project,the pile foundation type is prestressed concrete pipe pile.Before construction,it should select the type of pile driver and accept the finished pile.There are corresponding technical measures for pile sending,pile sinking and pile connection during construction.The characteristics of prestressed concrete pipe piles are high single pile bearing capacity,good quality,fast construction,good civilized construction,and good comprehensive benefits.These characteristics are reflected in this project.
