摘要
The present invention excavates the ground to a certain depth, lay a precast concrete panel on the excavation surface, and after the pile is driven on the precast concrete panel, the casting and curing between the precast concrete panel and the pile with non-concrete concrete Accordingly, an object of the present invention is to provide a freeze protection structure for railway roadbeds and a construction method thereof in which pile and precast concrete panels absorb the expansion pressure due to winter frost, thereby reducing freezing and rising of the track in winter. Railroad roadbed freeze protection structure according to the present invention for achieving the above object is a precast concrete panel having a predetermined width and thickness; A pile driven into the precast concrete panel; A gravel phase in which gravel is laid on the precast concrete panel to a predetermined thickness; PC sleeper that is placed on the gravel top; It consists of a rail fixedly installed by the fastening device on the PC sleeper. In addition, the method for constructing a freeze protection structure for railway roadbed according to the present invention for achieving the above object comprises the steps of excavating the ground to a certain depth to form an excavation surface; Installing a precast concrete panel on the excavation surface; Driving the pile into the precast concrete panel and inserting it into the ground; Placing and curing non-concrete concrete between the precast concrete panel and the pile; Spraying gravel on the precast concrete panel to form a gravel pattern; Laying a PC sleeper on the gravel phase; By sequentially performing the step of installing the rail with a fastening device on the PC sleeper, it characterized in that the construction of the freezing prevention structure.
