PHC预应力混凝土管桩静压施工方法

Static Press Construction Method with PHC Prestressed Concrete Pipe Pile

PHC管桩静压法施工,是通过桩机自带吊装设备或另配吊机吊装、喂桩,静压桩机将预应力高强混凝土管桩(简称PHC桩)压人土中的一种沉桩工艺,与锤击法管桩施工工艺相比,具有低噪声、低污染、对土层及周边建(构)筑物影响小、桩身质量破坏小的特性。在天津站改扩建无站台柱雨棚工程桩基施工中,采用了静压施工技术,收到了良好的社会效益与经济效益。

Static press construction method with PHC pipe pile is a pile driving technology that uses static press pile machine to press the prestressed concrete pipe pile(PHC pile) into the ground. It has the characteristics of low noise and pollution,a little influence on the soil layer and surrounding buildings,and a little damage to pile quality. The static press construction technology is applied in the pile construction for no-platform-column canopy project of reconstruction of Tianjin Station,and achieves well social and economic benefits.
