Novel marine bridge concrete structure anti-corrosion construction technology
The invention discloses a novel marine bridge concrete structure anti-corrosion construction process, and provides a construction process for externally spraying silane for impregnation, which not only depends on measures such as optimization design of epoxy steel bars, high-performance marine concrete and a steel bar protective layer for durability of bridge structure concrete in a marine corrosion environment, but also needs some auxiliary measures. In the aspect of guaranteeing construction safety, especially in the aspect of surface treatment details for guaranteeing the spraying effect, the spraying effect is better guaranteed in the aspects of repair treatment of pull rods, repair treatment of cracks, treatment of surface looseness and pollution, regulation of the surface drying degree and the like in formwork construction; and the spraying effect is verified according to the reduction effect detection indexes of the solid coring water absorption rate, the dipping depth and the chloride absorption content. The anti-corrosion technology and conventional measures form an organic whole, the bridge durability anti-corrosion measures are perfected in the construction period, and then the durability of the sea-crossing bridge in the trial period is effectively protected.
本发明公开了一种新型海洋桥梁混凝土结构防腐施工工艺，海洋腐蚀环境桥梁结构混凝土耐久性不仅依靠环氧钢筋、高性能海工混凝土、钢筋保护层优化设计等措施，还需要一些辅助措施，本发明提供一种外喷硅烷浸渍的施工工艺，在保障施工安全方面，尤其是在保障喷涂效果的表面处理细节方面的步骤，对于模板施工的对拉杆的修复处理、裂缝的修复处理、表面松散及污染的处理、表面干燥程度的规定等方面更好的保证喷涂效果，对实体取芯吸水率、浸渍深度以及氯化物吸收含量的降低效果检测指标进行验证喷涂效果。本发明防腐工艺与常规措施形成有机整体，把桥梁耐久防腐措施在建设期完善，进而有效保护跨海桥梁在试用期时的耐久性。
