Construction Technology of Double-block Ballastless Track in Winter
At present,the rapid development of China's high-speed rail,continuously improve project quality and efficiency requirements,no frantic jumble orbit as the node of high-speed rail construction project is affected by the requirement of time limit for a project is often the need for preservation and maintenance of concrete in winter construction will directly affect the concrete strength and other physical quality,is a fran-tic jumble orbit of the main problems in the winter construction need to adopt traditional winter cover the way heat preservation quilt,curing effect is poorer,early strength increase slower,restricted construction efficiency double block without a frantic jumble rail set-up greenhouses steam curing winter construction technology by membrane wet quilt insulation plastic water lock A complete set of measures,such as sandbag windbreak,can ensure the construction quality and construction efficiency of ballastless track in winter.
