随着大跨径桥梁、高架桥、立交桥的大量兴建,桥梁结构防水技术的使用越来越广泛,混凝土桥面漏水会腐蚀钢筋,降低混凝土强度,缩短结构的使用寿命。由于不少桥梁不做防水或防水不力造成桥面渗水、钢筋锈蚀、铺装层剥落、碱骨料反应、钢筋锈蚀而引起的混凝土胀裂等严重的损坏问题,因此必须加强桥梁的防水,确保桥梁的正常使用。 With the large-scale construction of large-span bridges, viaducts and overpasses, the use of bridge structure waterproofing technology is more and more widely. Water leakage from concrete bridge decks will erode the reinforcement, reduce the strength of concrete and shorten the service life of the structure. Because many bridges do not make waterproof or ineffective waterproof bridge deck water seepage, corrosion of steel, pavement peeling, alkali aggregate reaction, steel corrosion caused by concrete cracking and other serious damage problems, it is necessary to strengthen the bridge waterproof, to ensure that The normal use of the bridge.
