Bridge pier structure crack repairing method
The invention relates to the technical field of bridge pier crack repairing, and discloses a bridge pier structure crack repairing method which is carried out according to the following steps: step 1, checking and counting the number and position of cracks existing in a bridge pier, chiseling off painting layers on the surfaces of the cracks by using an electric pick aiming at a bridge pier cracking area, and cleaning disintegrating slag; 2, a high-pressure spray gun is used for pouring R70 high-strength anti-seepage mortar into the gap, and the structure gap is filled; and 3, after the R70 high-strength anti-seepage mortar is completely dried, the outer surface of the structural joint is scraped with the R70 high-strength anti-seepage mortar in batches, and leveling and leveling are conducted. After the D200 interface agent is dried and cured, the T303 transparent protective coating is sprayed, and after the T303 transparent protective coating is in contact with air, the T303 transparent protective coating converges to form a film and is ceramized, so that the unique protective coating with hydrophobic and oleophobic functions is provided for the surface of the pier, the pier is endowed with better durability, and the outer surface of the pier has certain self-cleaning capacity.
本发明涉及桥墩裂缝修复技术领域，且公开了一种桥墩结构裂缝修复方法，按如下步骤进行：步骤一：检查并统计桥墩存在裂缝的数量和位置，针对桥墩开裂区域，使用电镐将裂缝表面的粉刷层凿除，并且清理碎渣；步骤二：使用高压喷枪将R70高强防渗砂浆灌入缝隙内，对结构缝隙进行填充；步骤三：待R70高强防渗砂浆完全干燥后，在结构缝外表面批刮R70高强防渗砂浆，并且找平收光。本发明通过在D200界面剂干燥固化后，喷涂T303透明防护涂层，与空气接触后会聚合成膜并陶瓷化，从而为桥墩的表面提供一个独特的具有疏水和疏油功能的防护涂层，赋予桥墩更好的耐久性，并且使得桥墩外表面具有一定的自洁能力。
