一、概况钢筋混凝土预应力宽轨枕——即轨枕版,是我国铁路基础重型化的一个组成部份,轨枕版的铺设对加强轨道结构强度,提高运输能力,稳定线路,减少养护人工都有很好的作用。轨枕版在我国雨量充沛,地下水位高的苏南地区铺设,路基排水工作更为突出。根据轨枕版的特点,轨枕铺满整个道床,轨枕之间无间隙,道床内的水份不容易通过大气蒸发,这样排水问题如果不解决好,轨枕版铺设以后不但不能发挥他的优势,相反会引起很多的麻烦,投入更多的劳力、财力去整治线路翻浆冒泥,这一点我段有深刻的教训。
I. Overview Reinforced concrete prestressed wide sleeper - sleeper, that is, the basis of heavy railways in China is an integral part of the laying of the sleeper rail structure to strengthen the strength and improve transport capacity, stabilize the line, reducing the maintenance of labor are very Good effect. Sleepers in our abundant rainfall, high groundwater level in southern Jiangsu laying, subgrade drainage work more prominent. According to the characteristics of the sleeper, sleepers covered the entire track bed, sleepers without gaps between the moisture in the ballast bed is not easy to evaporate through the atmosphere, so if you do not solve the drainage problems, the sleeper after the laying of the future will not only not play his advantage, on the contrary will Cause a lot of troubles, put more labor and financial resources to remediation of the pipeline to get muddy. This point, I have a profound lesson.
