Winter construction method for self-compacting concrete of tunnel ballastless track
The invention discloses a winter construction method for self-compacting concrete of a tunnel ballastless track. The winter construction method for the self-compacting concrete of the tunnel ballastless track comprises a tunnel exterior self-compacting concrete winter construction procedure and a tunnel interior self-compacting concrete winter construction procedure. Tunnel section self-compactingconcrete is maintained through a method of combining plastic cloth and a heat preservation quilt, and in construction, a construction method is selected according to the air temperature condition, the engineering structure condition, the construction period urgency degree, the cement variety and price, the performance and price of an early strength agent, a reducing agent and an anti-freezing agent, the performance and price of a heat preservation material, the conditions of a heat source and the like during construction; and certain economic benefits are brought, by applying the winter construction method for the self-compacting concrete of a CRTS III type plate ballastless track, the construction time of worker operation is effectively shortened, the working efficiency is improved, it is guaranteed that workers can return to the countryside on time in the Spring Festival, and good social benefits are achieved.
本发明公开了一种隧道无砟轨道自密实混凝土冬季施工方法，所述的隧道无砟轨道自密实混凝土冬季施工方法包括隧道外自密实混凝土冬季施工程序和隧道内自密实混凝土冬季施工程序。隧道地段自密实混凝土采用塑料布加保温被的方法进行养护，在施工中，根据施工时的气温情况，工程结构状况，工期紧迫程度，水泥的品种及价格，早强剂、减少剂、抗冻剂的性能及价格，保温材料的性能及价格，热源的条件等，来选择施工方法，带来一定的经济效益，且通过对CRTSⅢ型板式无砟轨道自密实混凝土冬季施工方法的运用，有效降低了工人作业的施工时间，提高了工作效率，保证了工人能在春节期间按时返乡，起到了较好的社会效益。
