Novel repairing method for bridge pier cracks immersed underwater
The invention discloses a novel repairing method for bridge pier cracks immersed underwater, which comprises the following steps: 1, bridge pier crack treatment: carrying out preliminary cleaning on the bridge pier cracks, covering the bridge pier cracks by using a rubber template, and reserving an upper side channel and a lower side channel during covering; sealing treatment being conducted between the rubber template and the surface of the to-be-repaired pier; 2, drainage and exhaust treatment: carrying out drainage treatment on the interior of the bridge pier, and discharging liquid in the bridge pier through a lower side channel, so that accumulated water in the cracks of the bridge pier is completely discharged and is full of gas; then performing exhaust treatment, pumping gas in the bridge pier out through the upper side channel, so that a negative pressure environment is formed in the crack of the bridge pier; and 3, filling: connecting a lower side pipeline with a filling machine, quickly filling the bridge pier crack with the filler from bottom to top due to pressure difference, and completely filling the bridge pier crack when the filler overflows from the outlet of an upper side pipeline. The method can be used for repairing crack wounds of bridge piers in any shapes underwater.
本发明公开了一种针对浸没于水下的桥墩裂纹的新型修补方法，该方法步骤如下：1.桥墩裂纹处理：对桥墩裂纹进行初步的清洁，使用橡胶模板对桥墩裂纹进行覆盖，覆盖时预留出上侧通道与下侧通道；并对橡胶模板与待修复的桥墩表面之间进行密封处理；2.排水排气处理：对桥墩内部进行排水处理，桥墩内部的液体通过下侧通道排出，从而使桥墩裂纹内部积水排净、充满气体；然后进行排气处理，通过上侧通道抽出桥墩内部的气体，使桥墩裂纹内部形成负压环境；3.填料：使下侧管道与填料机连接，由于压强差，填料将会自下而上快速填充桥墩裂缝，当上侧管道出口有填料溢出则桥墩裂纹全部填补完毕。该方法可实现在水下对任意形状桥墩裂纹创伤的修补。
