Fabricated steel tube constraint reinforced concrete bent frame pier
The invention discloses an assembly type steel pipe restrained reinforced concrete bent frame pier which is characterized in that an upper pouring groove is formed in an upper transverse restraining section, an upper pouring sleeve is mounted in the upper pouring groove, and concrete is poured, so that connection between a pier column and a cover beam can be realized, and meanwhile, an upper gap is formed between a steel pipe and the cover beam; similarly, a lower pouring groove is formed in the lower transverse constraint section, a lower pouring sleeve is installed in the lower pouring groove, concrete is poured in the lower pouring groove, connection between the pier column and the foundation can be achieved, and meanwhile a lower gap is formed between the steel pipe and the foundation; the upper transverse stress weak points and the lower transverse stress weak points are formed in the upper gap and the lower gap respectively, when geological disasters such as earthquakes occur, the upper transverse stress weak points and the lower transverse stress weak points lose efficacy firstly, so that other components can be protected against damage, and during later repair, the bent cap, the pier column and the foundation can be repaired only by resetting the bent cap, the pier column and the foundation. Concrete in the upper/lower pouring sleeve is taken out and then poured again, so that rapid reconstruction and recovery can be realized.
本发明公开了一种装配式钢管约束钢筋混凝土排架桥墩，通过在上横向约束段内设置上浇注槽，在上浇注槽内安装上浇注套筒并浇注混凝土，可实现墩柱与盖梁之间的连接，同时在钢管与盖梁之间形成上部间隙；同理，通过在下横向约束段内设置下浇注槽，在下浇注槽内安装下浇注套筒并浇注混凝土，可实现墩柱与基础之间的连接，同时在钢管与基础之间形成下部间隙；在上/下部间隙处分别形成上/下横向受力薄弱点，当发生地震等地质灾害时，上/下横向受力薄弱点和下横向受力薄弱点会首先失效，从而能够保护其他构件不受损伤，在进行后期修复时，仅需将盖梁、墩柱和基础复位后，将上/下浇注套筒内的混凝土掏出后重新浇注即可，可实现快速重建恢复。
