工程[原创] 混凝土搅拌站冬季施工技术-燕京宝玉-搜狐博客（Engineering [concrete] concrete mixing station winter construction technology - Yanjing Baoyu - Sohu blog） [ [original] label station in winter construction technology of concrete mixing: classification of Railway Passenger Dedicated Line: personal works of 2007-10-22 15:04 The construction technology of concrete mixing station in winter CCCC Luqiao Group Harbin Dalian passenger railway line project manager Xu Jianhua 2007-10-20 Introduction Located in the Northeast Central Plains Changchun, belongs to the high latitude area. The transition zone between the Changchun city climate between eastern and Western Mountain humid plains in semi arid area, semi humid temperate continental monsoon climate types. The eastern and Southern Ocean not far away though, but due to blocking the Changbai Mountains, weaken the summer monsoon; North and West is flat in the Songliao plain, Siberia smoothly polar continental air mass, the great influence of the monsoon. Changchun winter climate characteristics: The annual average temperature of 4.6 degrees; the long cold winter, the coldest in January, the minimum temperature of minus 36.5 degrees, the average temperature of minus 17.2 degrees celsius. Changchun is located in the hinterland of Songliao plain, four seasons climate. In the actual construction period of only 7 months. Winter construction technology has yet to find out effective solutions. Of Harbin Dalian passenger railway line, the construction period will be extended accordingly will become an indisputable fact. And the project of railway passenger dedicated line including civil, electrical, signal, disaster prevention, environmental control and other sub projects, involving dozens of professional, it is difficult to greatly shorten the construction period. 1, winter construction line: Where the daily average outdoor temperature for five days stability is lower than 5 DEG C, namely into the winter period of construction. In the winter construc
