Study Of CA Mortar Mixture Ratio And Construction Technology For Slab Track On Qin-Shen Passenger Railway

High-speed track proposes higher demands for subgrade and bed. The application of ballastless slab track is the main tendency for assuring the high stability and smooth of the track. The elasticity adjustable layer of slab track is a C A mortar mixture, which fuction is to provide the reasonable elasticity of track and is the key part of track structure.Firstly, in this thesis, the concert ratio and confecting technics of CA mortar mixture are researched out through the analyzing the 12 technic index and 13 kinds of composed materials despite locking of the related experience in our country. The research of various index of CA mortar mixture is accomplished. The materials made in our country are fully used. The materials are easy to get and the CA mortar mixture is free of pollution and much cheaper than those made in other countries. The capability of . CA mortar mixture completely satisfies the design demands.Secondly, in this thesis, the whipping machine, mobile trolley, affusing filler, material-delivering flat vehicle for producing CA mortar mixture are developed, and the capabilities of the equipments can make the need of productions. These equipments are of few number, easy to operate, no needing to be transported for long distance and reducing the separating of CA mortar mixture.At the last , the contruction technics of slab track are summarized, which fully satisfies the demand for contructing and assures the quality of engineerings. The technics involves the fixing of track slab, the fixing of side midule and affusing technics for CA mortar mixture. It has been proved through practice that the technics is of simpleness, choiceness in contruction quality, low labour intensity. This technics is first created in our country.
