摘要
根据岔区板式无砟轨道结构的特殊性以及施工特点,结合以往的施工经验,对自密实混凝土配合比进行了优化改良,为确保津秦铁路客运专线岔区板式无砟轨道铺设任务的顺利进行提供了可靠有利的帮助,同时也为今后此类施工提供参考。
In view of the structural specialties and construction features of turnout lab track special structure, combined with previous construction experience, improvement is made successfully on self-compacting concrete which ensure the com- pletion of slab ballastless track laying for the bifurcated zone of Tianjin and Qinhuangdao passenger dedicated railway, this paper provides a reference for similar projects.
