Steel cofferdam bottom sealing concrete back pressure structure and method
The invention relates to a steel cofferdam bottom sealing concrete back pressure structure and method.The steel cofferdam bottom sealing concrete back pressure structure comprises pile foundation concrete 20, pile foundation steel bars 21, pile foundation steel casings 22 and bottom sealing concrete 30 of a steel cofferdam, a back pressure seat 10 and a back pressure groove 40 are arranged, the back pressure seat 10 is arranged in the back pressure groove 40, one end of the back pressure seat 10 is supported on the pile foundation concrete 20 on the bottom face of the back pressure groove, and the other end of the back pressure seat 10 is supported on the pile foundation steel bars 21. And the other end of the back pressure seat 10 is supported on bottom sealing concrete 30 on the bottom surface of the back pressure groove, and the back pressure seat 10 is downwards compacted by adopting a steel bar threaded sleeve 23. The device has the beneficial effects that the back pressure seat is compacted on the pile foundation concrete and the bottom sealing concrete by utilizing the steel bar threaded sleeve by utilizing a steel bar threaded sleeve connecting technology which is popularized and applied at present and a threaded joint of the pile foundation steel bar, so that the bottom sealing concrete overcomes the upward buoyancy and keeps stable.
本发明涉及一种钢围堰封底混凝土反压结构及方法，包括钢围堰的桩基混凝土20、桩基钢筋21、桩基钢护筒22和封底混凝土30，设有反压座10和反压槽40，所述反压座10设置在所述反压槽内40，所述反压座10的一端支撑于反压槽底面的桩基混凝土20上，所述反压座10的另一端支撑于反压槽底面的封底混凝土30上，采用钢筋螺纹套筒23向下压实所述反压座10。本发明的有益效果是：利用目前已普及应用的钢筋螺纹套筒连接技术，利用桩基钢筋的螺纹接头，采用钢筋螺纹套筒将反压座压实在桩基混凝土和封底混凝土上，使封底混凝土克服上浮力，保持稳定。
