Concrete pier column construction method based on leakage prevention and falling prevention of formwork
According to the concrete pier column construction method based on leakage prevention and falling prevention of the formwork, a grout leakage prevention technology is innovatively adopted, namely, a grout stopping device is installed on the bottom face of the formwork, and due to the fact that a rubber grout stopping rod of the grout stopping device has enough elasticity, toughness and flexibility, the grout stopping rod is not prone to deformation; a hole between the formwork and a concrete surface can be filled through the compression performance of the rubber grout stop rod, so that downward leakage of concrete grout is effectively prevented, and the technical problem that in the pier column construction process, leaked grout pollutes a pier body below is solved. In addition, according to the concrete pier column construction method based on leakage prevention and falling prevention of the formwork, the falling prevention technology is innovatively adopted, namely, the falling prevention device is installed on the steel frame framework of the upper pier body, when the overturning and falling conditions occur, the supporting beams of the falling prevention device are arranged on the steel bar framework in a cross-arm mode, and therefore the frame body is prevented from falling; the problem that in the pier column construction process, overturning and falling safety accidents are likely to happen is solved.
本发明提供了一种基于模板防漏防坠的混凝土墩柱施工方法，该基于模板防漏防坠的施工方法，创新采用了防漏浆技术，即在模板的底面安装止浆装置，由于止浆装置的橡胶止浆棒具有足够的弹性、韧性、伸缩性，能够通过橡胶止浆棒的压缩性能填塞模板与混凝土面之间的孔隙，从而有效阻止混凝土浆液的下漏，解决了墩柱施工过程中漏浆污染下方墩身的技术难题。此外，该基于模板防漏防坠的混凝土墩柱施工方法，还创新采用了防坠技术，即在上节墩身的钢架骨架上安装防坠装置，当发生倾覆坠落状况时，通过防坠装置的支撑梁横担在钢筋骨架上，防止架体坠落，解决了在墩柱施工过程中易发生倾覆坠落安全事故的问题。
