WIDE SLEEPER FOR DIRECT FASTENED TRACK ON ASPHALT ROADBED, AND CONSTRUCTING METHOD FOR THE SAME

摘要

The present invention provides the construction methods of wide pillow pitch direct fastening rail and roadbed,The pitch roadbed of its stress that can minimize generation is by train load by forming pitch roadbed direct fastening rail of the broad tie with wide downside than general sleeper as the exclusive sleeper of pitch,Minimizing thickness asphalt road gene this,Reduce the plastic deformation of pitch roadbed,Level is generated by reducing stress,Guarantee safety and has trained the track of drive efficiency,By effectively controlling the horizontal force of generation in machine and transverse direction in the wide advance account of getting up late of two wide units of the downside that the partial correction construction error pitch roadbed construction for the center sleeper that installation shearing enhancement device is a round concrete segment high-strength concrete is attached to geotextile when broad tie is formed manufacture broad tie,Prevent that stress from concentrating and premature degradation by Transmit evenly train load to pitch roadbed,The downside broad way base sleeper and pitch of frictional resistance between raising,Controlled level power acts on vertical and horizontal direction. ;The 2016 of copyright KIPO submissions
