Research Of Maintenance Technology For Small Radius Curve And Big Rampway Interval Cwr

In this paper, through the stability analysis of jointless track and the construction discussion of laying the block in the small radius curve and long ramp location , the common disease have been investigated in detail for seamless line in the small radius curve location, and adopted the corresponding countermeasure after analysed synthetically. Combining the practical experience for seamless line in the small radius curve and long ramp location by Changzhi North worker bureau(长治北工务段),and in allusion to the characteristic for seamless line of small radius curve ,it trys to find out the law constantly ,renovates synthetically the disease, summarizes a set of methods of maintaining better ,takes certain line strengthening measure , dispels the unsafety factor for seamless line of small radius curve , improves security ability of the equipment and guarantees that the line equipment of dynamic and static state of quality is raised progressively. It also can offer consulting and basis for maintaining of seamless line of small radius curve line, reduce the work load, raise labour efficiency, and reduce the maintenance cost finally.
