New Construction Technology Research Of Ballastless Track

With the high-speed continual and steady development of China's economy in recent years, the country strengthened the paces of the railway construction at the same time, in order to meet country's economic and growing need. Among them there is not a kind of trend that has cut the overall expansion of the track and already become construction and development of future high-speed railway of our country in the passenger dedicated railway.Since the implementation of the《China railway network planning of long-term》,Our country under construction passenger traffic special line have military wide, Xi, Kazakhstan loud, stone Zheng very much,etc. at present, among them structural forms of the track are different to the limit too, if the military wide radar that adopts is 2000 type, the general forest type of brilliance of the rising sun which Zheng Xi adopted, modes in Chinese operatic music of Bogg adopted in Beijing and Tianjin,etc. Seeing that the radar has no track of cutting and has characteristics such as good structural continuity, getting smooth-going, stability and reducing the work load of maintaining and maintaining facilities,etc.2000 typely, our country has used radars to have no track of cutting on the special line of military wide passenger traffic 2000 typely in an all-round way for the first time too.The radar is too 2000 type to cut the construction craft of the track as a great deal of key technology and a very important component of special line of passenger traffic, before constructing, subsided after the line made the road bed, bridge, tunnel worker and the bridge shrank and should creep after meeting the designing requirement, can have no track of cutting to construct. It is mainly made up of following craft:Assign the base a control network (CPIII), examine and have the base of encrypting to mark--Pave one storey of concrete of supporting of the road bed and tunnel location, build the concrete antiabrasion layer and protruding platform on the bridge --Sleeper, tool rail, reinforcing bar,etc. construct material transport and unload --Lay localization one of the intermediate layer, fixed horizontal template of installation --Get into the hole of pins, lay the reinforcing bar of longitudinal ground floor --Cloth pillow, equipment rail are arranged, install spiral shell's pole adjuster baseplate, the firm pin of anchor --Thick to transfer rail arrange, lashing reinforcing bar network, earthing weld --Install the vertical horizontal template--Adjust the rail to arrange precisely, the rail is arranged fixedly --Build concrete of a bed board- -Remove the adjuster, relax the fastener, the temperature stress that diffuse, the concrete keeps in good health --Remove the template and tool rail, enter the next circulation.Generally speaking, radar 2000 type pairs of pieces of type have, cut track construct of our country's at a high speed railway construction at the starting stage evening, there are no construction experience and technology to accumulate yet, so should summarize and innovate and draw lessons from foreign and advanced construction craft and idea in our construction afterwards at the same time constantly, form one set and suitable for the special line of passenger traffic of our country and has not cut the technological administrative system that the track constructed finally.
