The invention relates to the technical field of road maintenance, in particular to an anti-corrosion and anti-seepage construction method of a bridge anti-collision wall for road maintenance, which comprises the following steps: during bridge asphalt felt construction, cutting asphalt felt into a strip with the width of 40cm, heating and softening the asphalt felt by using a blast lamp and other heating tools, and adhering the asphalt felt to a cleaned pitted surface at the lower part of the anti-collision wall; the adhesion height is about 30 cm, meanwhile, after the joint of the anti-collision wall and the bridge deck is cleaned, the asphalt felt is adhered to a bridge deck pavement layer by 10 cm, the adhered part is subjected to secondary heating after adhesion, firm and dense adhesion is ensured, and water, snow and a snow melting agent are completely prevented from invading the anti-collision wall and a gap in the lower portion of the anti-collision wall by means of the waterproof and anti-corrosion characteristics of the asphalt felt; and corrosion to the anti-collision wall and infiltration of bridge floor water are avoided.
本发明涉及公路养护技术领域，具体是指一种公路养护用桥梁防撞墙防腐防渗施工方法，桥梁油毛毡施工时，可先将油毛毡裁剪为40厘米宽的长条状，利用喷灯等加热工具，将油毛毡加热软化，粘贴于防撞墙下部已清洗麻面处，粘贴高度约为30厘米，同时对防撞墙与桥面接缝处进行清理后将油毛毡粘贴于桥面铺装层上10厘米，粘贴后对已粘贴部位进行二次加热，保证粘贴牢固，密实，利用油毛毡防水、防腐的特性，完全阻隔水、雪、融雪剂侵入防撞墙及防撞墙下部缝隙，避免对防撞墙的侵蚀及桥面水的下渗。
