在綫路上鋪設鋼筋混凝土軌枕,給大、维修作业提出了一系列新課題,特別是拨遺作业。由于鋼筋混凝土軌枕重量大,底面有凹坑,增大了阻力,用撬棍难以拨动,因此,有的使用压机拨道。但压机拨道却存在一些难以克服的缺点,即:压机横臥頂着鋼軌拨道时,因力量集中,使軌枕扣件及挡肩都受到損伤,并且容易把一个小弯拨成两个小弯。我們研究在不增加新工具的基础上,从改进压机着手,經过吉林、梅河口工务段的技术人員协助和水帘洞、营城养路工区工人們的反复討論試驗,終于成功,使用效果良好。現将有关的几个問題,概述如下。
The laying of reinforced concrete sleepers on the line, to the large, maintenance operations proposed a series of new topics, in particular, assigning assignments. Due to the heavy weight of the reinforced concrete sleeper, the bottom of the pit, increasing the resistance, with crowbar hard toggle, therefore, some use of press dial. However, there are some difficulties with the press track, which are as follows: When the press is lying on the rail track, the sleeper fastener and the shoulder block are damaged due to the concentrated force, and it is easy to dial a small bend into two A small bend. On the basis of not adding new tools, we studied with the assistance of technicians in Jilin and Meihekou Public Works Section and workers in Shuilian Cave and Yingcheng Maintenance Station, finally succeeded and used the results good. The relevant issues will be summarized as follows.
