摘要
随着我国铁路建设网络的规模不断扩大,需对既有站场进行扩建改造施工,以满足扩能需要,因此,需要对既有站场进行大量道岔插铺施工。文章以广州枢纽东北货车外绕线石滩站站场扩建工程为实例,研究石滩站站场扩建工程中交叉渡线道岔插铺工艺的改进,探讨单开道岔与交叉渡线道岔插铺的最佳施工方案,以提高施工效率。
With the continuous expansion of China’s railway construction network,the existing stations need to be expanded and reconstructed to meet the needs of capacity expansion.Therefore,it is necessary to carry out a large number of turnout insertion paving construction in the existing stations.Taking the expansion project of Shitan station on Guangzhou Hub Northeast Truck Outer Line as an example,this paper studies the improvement of the crossover turnout insertion paving technology in the expansion project of Shitan station,and discusses the best construction scheme for single turnout and crossover turnout insertion paving,so as to improve the construction efficiency.
