Abstract:
There are strict requirements for the construction survey of biblock ballastless tracks.The survey means and methods for the biblock ballastless track are very advanced.GEDO CE track inspection trolley is used for the survey of the biblock ballastless tracks in long tunnels. The principle, methods and procedures of the survey of biblock ballastless track are presented and discussed.Conclusions drawn are as follows: 1) The key for ballastless tracks to achieve the designed functions lies the process control of the fine adjustment survey; 2) The most important indexes of the static fine adjustment are the control of the elevation and direction of tracks with 10 mlong chord and the variation of these two indexes will directly influence the dynamic acceptance of the works.
Key words: biblock ballastless track, geometrical dimension, trackinspecting trolley, rough adjustment, fine adjustment
