In recent years, during the detection of the established reinforced concrete or the prestressed concrete box girder bridges etc . the large structures, we can find that the concrete in particular structural positions such as the anchorage zones of prestressed reinforcement with dense reinforcement, the prestressed pipe in which the space of reinforcement or the thickness of concrete cover is small, the top and bottom flange of box girder and so on has brought great difficulty to concrete construction because of the small size and densely-packed reinforcement 對于變截面t梁、工字梁、箱梁等常見結(jié)構(gòu),截面形式復(fù)雜,一些部位尺寸較小且密集配筋,如梁頂板,梁底板,預(yù)應(yīng)力管道間,混凝土不可避免的造成不密實導(dǎo)致耐久性降低,而這些問題往往為設(shè)計者所忽略。對于新建橋梁混凝土的密實度問題,尤其是新建橋梁關(guān)鍵部位的混凝土密實度和耐久性問題,人們研究和關(guān)心的較少,這也為橋梁的質(zhì)量監(jiān)督控制和使用壽命埋下了隱患。
