Research Of Maintenance Equipment And Correlation Aboutraise Speed Of Exiting Railway Line

It is very important to solve the problem of restricted reconstruction in the exiting line with the speediness development of all over the world railway and with the construction of high speed railway and the bigness spread of reconstruction in the existing line .It needs to weave a technique condition adapt to reconstruction of high speed railway in the existing line and to confirm the standard of which line section need to rebuild priority. This article stress to analyze about the equipment of permanent way in the exiting line or correlative content, combine several raise speed experience inner nation, through set up math modal experiment data and theory formula, stress to investigate plane condition about fit with existing line raise speed rebuild, satisfy curve radius choice in different velocity target value, confirm plane element of the transition curve length. Why to recommend adopt continue line and how to lay continue line. According to different raise velocity target data, it adopts relevant shift type, how to exchange high speed shift to combine station reconstruction in exiting line. Analysis procreant subgrade disease with raise speed of existing line. Though analysis for highway transition between rode and bridge, search technical standard of the disposal method for railway raise speed transition; How to bring into play maximal benefit from dive into fare of raise speed reconstruction in existing line introduce the concept "rate time divide fund ". Through the relation of dive into fund and timesaver research how to carve up section with different velocity for raise speed line. How to confirm section in reason velocity target data. How to combine exiting productivity position redressal to save investment ate. Thereinafter educe universality guidance disciplinarian of exiting line raise speed, for other raise speed line reference.
