| Abstract: | In Nanjing Hangzhou passenger dedicated rail construction, there is a operation cohesion contradiction among long line transport, stress release and lock construction, and there exists big mutual interference and low construction efficiency. Nanjing Hangzhou passenger special laying project adopts the construction organization mode of optimizing the seamless line and stress dispersion and locking process. In field welding, the method of ＂face-down bonding＂ is used, which has achieved good results and accelerated the construction schedule. |
