Spray operations are the primary means of precast health, roads and bridges, but the traditional process regimen once mostly water use,water pollution caused by waste and the environment. Regimen us-ing water collection, filtration and recycling processes can effectively improve the utilization efficiency of water conservation,not only reduces the cost of the project to improve the health quality,but with signifi-cant reductions environmental effects.%喷淋作业是目前道路桥梁预制件养生的主要手段,但传统工艺中的养生用水大多为一次使用,造成水资源的浪费和环境的污染。采用养生用水的收集、过滤和循环再用工艺可有效提高养护用水的利用效率,不仅降低了工程成本,提高了养生质量,而且具有显著的减排环保效果。
