预制管桩桩头灌芯施工技术

CONSTRUCTION TECHNOLOGY OF FILLING CONCRETE FOR PRESTRESSED CONCRETE PIPE PILE HEAD

预制管桩作为一种新型的桩基础具有工程造价便宜、桩身内空、强度高、混凝土用量少,节约资源、便于施工等优点,如何做好预制管桩灌注封堵成为了运用管桩施工的质量重点。嘉祥县人民医院新院区项目在预制管桩灌注封堵施工前,对桩头管芯技术进行了研究与讨论,创新了桩头封堵新技术,为类似工程提供了参考。

As a new type of pile foundation, prefabricated pipe piles have the advantages of low engineering cost, hollow inside the pile body, high strength, less concrete consumption, resource saving,and easy construction. The first quality threshold for the construction of various projects using pipe piles.Before the construction of prefabricated pipe piles, Jiaxiangxian People’s Hospital explored and discussed the technology of the pile head and pipe core, and innovated the new technology of pile head plugging.
