Construction method for maintenance of integrated layer of bridge floor
The invention relates to the technical field of bridge floor construction, in particular to a construction method for maintaining an integrated layer of a bridge floor. The method comprises the following steps: 1) pre-cleaning a pre-repaired part, and removing a broken plate and a broken plate; (2) crack sundries are removed, and it is ensured that the crack wall and the interior are clean and dry; (3) grouting is conducted, specifically, a repairing agent is poured into the cracks with the crack width smaller than 1 cm, and hot asphalt is poured into the cracks with the crack width larger than 1 cm; the repairing agent comprises the following components in parts by weight: 40-60 parts of special cement, 10-20 parts of liquid epoxy resin, 10-20 parts of water glass, 10-20 parts of polyacid polyol with the average molecular weight of 300-400, 3-5 parts of a UEA expanding agent, 3-5 parts of a CSA expanding agent, 5-10 parts of mineral oil, 5-10 parts of fly ash, 4-6 parts of hydroxypropyl methyl cellulose ether, 4-6 parts of a water reducing agent, 4-6 parts of fine aggregate and 0.5-3 parts of a defoaming agent.
本发明涉及桥面施工技术领域，具体而言，涉及一种用于桥面整体化层维修的施工方法。该方法包括如下步骤：1)对预修补处进行预清理，拆除破碎板、断板；2)清除裂缝杂物，确保缝壁及内部清洁、干燥；3)灌浆：对缝宽小于1cm的裂缝灌注修补剂，对于缝宽大于1cm的裂缝，将热沥青灌入缝内；所述修补剂以重量份计包括：特种水泥40～60份、液态环氧树脂10～20份、水玻璃10～20份、平均分子量为300～400的聚酸多元醇10～20份、UEA膨胀剂3～5份、CSA膨胀剂3～5份、矿物油5～10份、粉煤灰5～10份、羟丙基甲基纤维素醚4～6份、减水剂4～6份、细骨料4～6份以及消泡剂0.5～3份。
