Anti-floating structure of concrete structure of oversized conjoined basement
The invention relates to an anti-floating structure of a concrete structure of a super-large connected basement, which is characterized in that a pre-tensioning method prestressed high-strength concrete pipe pile is adopted, the prestressed high-strength concrete pipe pile is connected with a raft plate or a bearing platform to form a large sample, and then the pile is formed; the prestressed high-strength concrete pipe pile comprises a foundation pile and a C35 micro-expansion concrete filling core arranged in the foundation pile, the C35 micro-expansion concrete filling core comprises a reinforcement cage spiral bar and a flaring-shaped section located at the upper end of the reinforcement cage spiral bar, the flaring-shaped section extends into a pressing block on the upper portion of the foundation pile, and an upper round steel plate is fixedly arranged on the flaring-shaped section. The upper round steel plate is arranged on the top of the flaring-shaped section in a sleeved mode, the upper round steel plate comprises an upper base plate, upper positioning holes are formed in the upper base plate in an annular array mode, and steel bars at the upper end of the flaring-shaped section are correspondingly inserted into the upper positioning holes. On the premise that the cost is not increased basically, the construction quality is higher, the construction stability is high, and the construction efficiency is high.
本发明涉及一种超大连体地下室混凝土结构抗浮构造，采用先张法预应力高强混凝土管桩，先通过预应力高强混凝土管桩与筏板或承台连接大样后再成桩；所述的预应力高强混凝土管桩包括基桩和基桩内设置C35微膨胀砼填芯，所述的C35微膨胀砼填芯包括钢筋笼螺旋筋和位于钢筋笼螺旋筋上端的扩口状段，所述的扩口状段延伸置基桩上部的按实块中，所述的扩口状段上固设有上圆钢板；所述的上圆钢板套置于扩口状段顶部，所述的上圆钢板包括上基板，上基板上环形阵列有上定位孔，扩口状段的上端钢筋对应插置于所述的上定位孔中。本发明在基本不增加成本的前题下构造质量更高，构造稳固性强且构造效率高。
