通州市建工大厦工程基础施工中 ,采用超高强预应力混凝土管桩(PHC桩) ,打桩前需做好桩锤、桩架选择 ,确定管桩龄期 ,打桩过程中插桩、锤打、接桩、送桩均采取了相应的技术措施。该工程中PHC桩所具有的单桩承载力高、桩身耐锤击性好、穿透力强、造价便宜等特点均得到很好的体现。
Tongzhou City Construction Engineering Building Foundation construction, the use of ultra-high-strength prestressed concrete pipe pile (PHC pile), piling need to be done before pile hammer, pile rack selection, to determine the pipe pile age, piling, hammering, Then pile, send pile have taken the appropriate technical measures. PHC pile in this project has a high single pile bearing capacity, good pile hammer resistance, penetrating power, low cost and other characteristics are well reflected.
