铁路双块式轨枕预制场建场设计技术研究

作为无砟轨道系统的主要类型之一,双块式轨枕已广泛应用于我国高速铁路,依托双块式轨枕的生产工艺流程要求,从轨枕预制场的整体规划、平面布置以及资源配置等方面对预制场建设进行全面分析。整体规划应结合全线的生产工期和供求半径确定预制场的生产能力;按照模块化的设计理念对各功能区进行独立设计,以轨枕生产车间模块为中心进行整体平面布置;资源配置时通过选取关键参数进行各功能区占地面积和机械、人员配置的公式化处理,实现双块式轨枕预制场建设的标准化和规范化。

Design Technology Research for Building a Precast Yard of Railway Bi-block Sleepers

As one of the main parts of ballastless track,the bi-block sleepers have been widely used in high-speed railways in China.This paper,according to the requirements of production process of bi-block sleepers,comprehensively analyzes how to build a precast yard of bi-block sleepers,from a number of aspects of a precast yard of bi-block sleepers such as the overall planning,plan layout,resource allocation and so on.The paper points out:(1) in the stage of overall planning,the production capacity of a precast yard should be determined in combination with the whole railway line's production period and in combination with the supply-demand radius;(2) in the stage of the plan layout,every function zone should independently be designed according to the design idea of modularization,and then the overall plan layout should be arranged around the module of sleeper manufacturing shop;(3) in the stage of resource allocation,the land area of every function zone as well as the machinery and personnel allocation should be formulized by means of selecting the key parameters,in order that the precast yard of bi-block sleepers can be built with standardization and normalization.
