Research conclusions:(1)In the producing process of the steel rails that slenderness ratio is 2168，the deformation is controlled，which plays a crucial role in successful trial-production of turnout.(2)The processing quality of the steel rails directly affects the turnout assembly，trial laying and the running state，which is the key of turnout manufacture. (3)The processing technology of the turnout mainly includes processing of steel rails such as switch rails，point rails， wing rails，as well as the plate processing and sulfidizing.(4)The key technology of turnout assembling and laying includes transformation of rail laying assembly platform，determining rail laying assembly benchmark，the initial assembly of rail，rail laying fine adjustment，and so on.(5)The current operation of Harbin-Dalian High Speed Railway shows that the technology of this kind of turnout is advanced enough to achieve the design and high speed running requirements，and is able to be widely used in the high speed railway which the side running speed is 220 km/h.
