目前公路木桥采用的防腐方法,计有扩散(即涂抹防腐浆膏及包扎防腐缠带)、热冷槽浸注及表面处理三种。它们的应用范围和处理过程,在以前公路总局印发的公路木桥防腐会议专刊,公路木结构防腐指南及1954年公路木桥防腐经验介绍等文件上,都有比较详细的介绍。但是,现在各地的木桥防腐处理还存在着一些问题,例如防腐方法的选择不很适当,浆膏涂层普遍地发生脱落现象等。为了改进防腐工作,仅在技术方面就我所了解的问题提出几点意见,以供大家参考和商讨。
Currently used wooden bridge anti-corrosion methods, there are proliferation (that is, coated anti-corrosion plaster and bandaging anti-corrosion tape), hot cold slot immersion and surface treatment of three. Their application scope and handling process are described in more detail in the documents such as the special edition of the Highway Bridge Preservation Conference, the Guide for Preservation of Highway Wood Structure and the Introduction of Preservation of Highway Wood Bridge in 1954. However, there are still some problems in anticorrosive treatment of wood bridge around now, for example, the choice of anticorrosive methods is not suitable, and the phenomenon of shedding of plaster generally occurs. In order to improve the anti-corrosion work, I only made a few technical suggestions on what I understand, for your reference and discussion.
