随着我国预应力和混凝土技术的高速发展,预应力高强混凝土管桩已被广泛应用于各类房屋建筑的基础工程中。由于预应力高强混凝土管桩具有施工工期短、成桩质量容易得到保证以及造价相对较低等优点,近年来,在我国得到了迅猛发展。本文结合广州市国家档案馆新馆一期工程案例介绍预应力管桩施工技术问题的一些关键环节。 With the rapid development of prestressed concrete technology in our country, the prestressed high strength concrete pipe pile has been widely used in the foundation engineering of various types of housing construction. As the prestressed high strength concrete pipe pile has the advantages of short construction period, easy to be piled quality and relatively low cost, in recent years, it has been developed rapidly in our country. In this paper, Guangzhou City, National Archives New Museum Phase I project case describes the key issues of prestressed pipe pile construction technology.
