摘要
详细介绍了道岔区长轨枕埋入式无砟轨道的施工关键技术,主要包括基标的测设、支承层施工、道岔轨排架设与调整、道床混凝土浇注等,同时,阐述了保证道岔区长轨枕埋入式无砟轨道施工质量的技术措施。其施工经验可供同类工程参考。
Introduced in detail in the paper are the key techniques for the construction of the buried ballastless tracks with longs leepers in switching districts,which mainly consist of the surveying and setting of the datum mark,the construction of the bearing layer,the laying and adjusting of the switching track bents,the pouring of concrete of the railroad bed,etc.,with technical measures to ensure the construction quality of the buried ballastless tracks with long sleepers in switching districts dealt with in the meanwhile.The construction experience of the project may serve as a useful reference for other similar projects.
