Main bridge steel structure construction method
The invention discloses a main bridge steel structure construction method which comprises the following steps: sequentially paving an epoxy asphalt carbon fiber protective layer, an epoxy asphalt macadam shear layer, an epoxy asphalt concrete layer, a modified epoxy waterproof reinforcing layer and a modified epoxy macadam micro-surfacing treatment layer on a steel structure bridge deck to finish the construction of the steel structure bridge deck of a main bridge. The main bridge steel structure construction method is low in construction environment temperature requirement, normal-temperature construction and normal-temperature curing are achieved, construction conditions are easy to achieve, construction is easy and convenient, by laying the six layers of protection structures on the steel structure bridge deck, the steel structure bridge deck is high in fatigue resistance, resistant to high temperature and water damage, waterproof and corrosion-resistant, the service life of a main bridge is prolonged, meanwhile, raw materials of the six-layer protection structure are common, so that later maintenance is convenient, and cost is low; according to the construction method, laying construction is conducted through the bridge deck laying construction equipment, and the bridge deck laying construction equipment is high in automation degree, high in construction efficiency and low in construction cost.
本发明公开了主桥钢结构施工方法，通过在钢结构桥桥面上依次铺设环氧沥青碳纤维防护层、环氧沥青碎石剪力层、环氧沥青混凝土层、改性环氧防水加固层及改性环氧碎石微表处理层，完成对主桥的钢结构桥桥面进行施工，该主桥钢结构施工方法对施工环境温度要求不高，常温施工，常温固化，施工条件易于达到，施工简便，通过在钢结构桥桥面铺设以上六层保护结构，使得该钢结构桥桥面抗疲劳性能强、耐高温、耐水损、防水防腐，提高了主桥的使用寿命，同时六层保护结构的原料常见，使得后期维护方便，费用低；该施工方法中通过桥面铺设施工设备进行铺设施工，该桥面铺设施工设备自动化程度高，施工效率快，施工成本低。
