四川省修建了很多座各种型式的大型木面桥车辆的磨损和木腐菌的侵害,木桥面的更换工作为养路部门一年一度的,也是最感头痛的工作。木桥面更换的特点是:分散、局部,面宽、为了配合运输需要,还得维持交通,也就是说要黑夜赶工。但黑夜赶工需要照明设备,同时还要保证工程质量和安全生产。特别是有些大桥,结构复杂,一夜完不成一孔,要维持通车在过去,是存在着很多困难的。泸定养路段在去年更换孔径128.4公尺的沪定大渡河吊桥时,首先碰到的就是这些问题:夜晚风大,煤气灯点不燃;若使用发电机,不但贵,而且找不到。怎样办?困难是难不住群众的,是难不住
In Sichuan Province, many large-scale wood-bridged vehicles of various types were built and worn by wood rot fungi. The replacement of wood-decked bridges was the annual and most troubling task for road maintenance departments. Wood deck replacement is characterized by: decentralized, local, wide, in order to meet the transport needs, have to maintain traffic, that is to night rush. However, rush night work requires lighting equipment, but also to ensure project quality and safety in production. In particular, some bridges, complicated in structure, fail to form a single hole in a single night. To maintain the traffic in the past, there are many difficulties. Luding maintenance section of the Huludao Dadu River suspension bridge of 128.4 meters in diameter last year, the first encounter is these problems: the night wind, gas lights point non-combustible; if you use the generator, not only expensive, but can not find. What to do? Difficulties are hard to live the masses, it is hard to live
