Coating type waterproof construction process for steel bridge deck
The invention discloses a coating type waterproof construction process for a steel bridge deck, which is characterized in that the coating operation is strictly prohibited under weather conditions such as raining, snowing, moisture condensation and wind power greater than or equal to level 5; reworking after raining, detecting the water content of the concrete panel of the segmental beam again before construction, and constructing after the requirement is met; when the waterproof coating is prepared, cured or caked unqualified coating is not mixed, the prepared coating can be used as soon as possible to avoid the influence on the bonding performance, and by adopting a dual waterproof technical measure and brushing an interface agent and a facility waterproof bonding layer, the water seepage disease is effectively prevented, and the waterproof performance of the bridge floor is enhanced; in the waterproof construction of the bridge floor, the overall quality of the bridge floor construction is ensured by detecting the performance index of the asphalt mixture material, enhancing the construction technology control of the bridge floor pavement structure layer, treating the sealing water at the edge of the bridge floor and preventing rainwater from permeating into the pavement layer.
本发明公开了钢桥面涂布式防水施工工艺，环境要求，遇下雨、下雪、结露、风力大于或等于5级等天气条件时，严禁涂布作业；下雨后复工，施工前应重新检测节段梁混凝土面板含水率，达到要求后方可施工；防水涂料配料时，不得混入已固化或结块的不合格涂料，且配制好的涂料应尽快使用，以免对粘结性能造成影响，采用双重防水技术措施，通过涂刷界面剂和设施防水黏结层，有效预防渗水病害，增强桥面防水性能；在桥面防水施工中，通过检测沥青混合料材料性能指标，加强桥面铺装结构层施工技术控制，处理好桥面边部封水，避免雨水渗透到铺装层，从而保证桥面施工整体质量。
