河北省交通厅于最近調查了1954～1956年之間木桥进行防腐的效果。調查所得的情况如下: 一、木桥防腐的一般情况河北省从1954年开始,各专区在新建木桥上全部进行了防腐,并有专人領导和掌握这一新的工作。但这一工作未能一直坚持。从1956年以后,就沒有专人負責指导,所以在省或者专区所修建的木桥沒有按“公路木結构防腐指南”要求作防腐,造成了一些不良后果。如栏杆和端面不作浆膏处理,但有的木桥却都涂刷上了瀝青防腐浆膏。榫头和隐蔽部份应涂刷浆膏两遍,但有的木桥却未作防腐处理等。从这次調查的实际观察中,发現在防腐工作中还存在着很多問題。几年来沒有进展的老 Hebei Provincial Communications Department recently investigated the effect of preservatives on wooden bridges from 1954 to 1956.
