Construction method for repairing bridge padstone defects
The invention discloses a construction method for repairing bridge padstone defects. The method comprises a cover beam, a defect padstone, a support and a main beam. The defect padstone is installed at a top of the cover beam, the support is installed at the top of the defect padstone, and the top of the support abuts against the bottom of the main beam. The construction method specifically comprises the following construction steps: arranging a temporary support; chiseling off a defect part of a defect padstone; drilling a steel bar embedding hole; embedding a steel bar; encapsulating the padstone; injecting high-strength shrinkage-free slurry and maintaining; and finally removing the temporary support to finish repair construction. According to the construction method for repairing the bridge padstone defects, a whole repairing process can be completed without jacking a main beam or dismounting a support system. And the construction process is simplified so that other adverse factorsinfluencing the bridge structure due to jacking of the main beam and dismounting of the support system are avoided. Moreover, by adopting the method to repair the padstone, the construction method issimple and convenient, a safety coefficient is good, and a repair effect is reliable.
本发明公开了一种桥梁垫石缺陷修复的施工方法，包括盖梁、缺陷垫石、支座和主梁，所述缺陷垫石安装在盖梁顶部，所述支座安装在缺陷垫石顶部，支座的顶部抵在主梁底部；具体包括如下施工步骤：设置临时支撑、凿除缺陷垫石的缺陷部分，钻植筋孔，植筋，包封垫石，注高强度无收缩浆液和养护，最后拆除临时支撑完成修复施工。本发明提供的桥梁垫石缺陷修复的施工方法，不需要顶升主梁，也不需要拆除支座系统，即可完成整个修复过程。简化了施工工序，也因此而规避了因顶升主梁和拆除支座系统造成的其他对桥梁结构有影响的不利因素。而且，采用本方法修复垫石，施工方法简便，安全系数较好，修复效果也很可靠。
