混凝土箱梁喷淋养护系统的设计与实现
|
摘要
针对传统的混凝土箱梁自然养护过程易受操作者主观因素影响,造成养护不及时、遗漏、难以标准化等问题,设计了以可编程逻辑控制器(PLC)为核心的自动喷淋养护系统。根据制梁场箱梁数量多、占地广、地理环境复杂等特点,采用扩频调制技术,既实现了分布式控制模块的远程数据交换,又实现了操作台、PLC、远程扩展模块以及传感器之间的信息互联。京沈线黑山制梁场的应用表明,该系统提高了自然养护条件下箱梁的品质,达到了设计目标,具有良好的工程应用前景。
Against to the issues that the traditional natural conserving process of concrete box girders is influenced easily by subjective factors of the operators,which causes the conserving process is not timely,being omitted,and difficult to be standardized,an automatic spraying conserving system with PLC as the core is designed. According to the features of beam fabrication field,e. g.,large number of box girders,covering a wide area,and complex geographical environment,the spread spectrum modulation technique is used to realize remote data exchange between distributed control modules; and information interconnection among console,PLC,remote expansion modules and sensors. The system has been applied in Heishan beam fields of Beijing-Shenyang railway,and the quality of box girders has been enhanced under natural conserving conditions; the design goals have been achieved; and a bright prospect of engineering application has been shown.
