Method for repairing tubular pile at fixed wharf
The invention relates to a method for repairing a pipe pile at a fixed wharf, and provides a method for repairing a pile foundation and a structure at the fixed wharf, which comprises the steps of repairing the pile foundation and repairing the structure, specifically, a knocking device is hoisted by a crane to act on a PHC pipe pile forming the pile foundation so as to remove impurities until a hard part is exposed or a reinforcing steel bar is planted; and then the sleeve is assembled and positioned to the periphery of the to-be-repaired PHC pipe pile, grouting is continuously completed in batches through pressure grouting, and repairing is completed through maintenance. The structure repairing is mainly used for repairing reinforced concrete structures at an approach bridge structure and a fixed wharf, and comprises crack repairing and concrete damage repairing; in the crack repairing process, pressure grouting is conducted on the vertical cracks from top to bottom, pressure grouting is conducted on the horizontal cracks from one end to the other end, and the pressure of pressure grouting is 0.2-0.8 MPa. And secondary damage caused by chiseling is avoided by utilizing the beating device.
本发明为固定码头处的管桩修复方法，提供了固定码头处的桩基和结构修复方法，包括桩基修复和结构修复，所述桩基修复中具体是通过吊机吊装敲打装置，使其作用于构成桩基的PHC管桩上，以清除杂质，直至露出坚硬部分或植钢筋，然拼装并定位套筒至待修复PHC管桩外周，以压力灌浆分批且连续完成灌浆，养护完成修复；所述结构修复，主要是对引桥结构处和固定码头处的钢筋砼结构修复，包括裂缝处修复和混凝土破损修复；所述裂缝处修复中，竖向缝按照自上而下的顺序，而水平缝则按照一端向另一端的顺序，进行压力灌浆，压力灌浆的压力为0.2‑0.8MPa。利用敲打装置，避免了凿除造成的二次伤害。
