我段管内京包线在1970至1972年将原有跨度为6.7～9.6米的钢梁更换为低高度钢筋混凝土梁时,有50座98孔采用了橡胶支座。橡胶支座的规格、型号不一,有240×170×30毫米,300×150×30毫米,200×150×30毫米等。前两种每片梁下设4个,后一种每片梁下设6个。通过五年来实践,我们对橡胶支座的使用、维修加深了认识。 When I replaced the steel beams between 6.7 and 9.6 meters in the original span between 1970 and 1972 for low-height reinforced concrete beams, 50 seats and 98 holes were made of rubber bearings. Rubber bearing specifications, models vary, there are 240 × 170 × 30 mm, 300 × 150 × 30 mm, 200 × 150 × 30 mm and so on. The first two beams under each set of four, the latter set each beam under six. After five years of practice, we deepened our understanding of the use and maintenance of rubber bearings.
