Adjustable plate-type ballastless track suitable for area with large foundation deformation risk
The invention relates to an adjustable plate-type ballastless track suitable for an area with a large foundation deformation risk. Once an existing ballastless track is formed, the existing ballastless track is difficult to adjust, and when an off-line foundation has large deformation, the off-line foundation is generally adjusted in a local cutting mode and the like, and the implementation difficulty is large. The device comprises a base plate, a prefabricated track plate is arranged above the base plate, adjustable mortar layer bags are arranged between the prefabricated track plate and the base plate, and the device comprises at least two layers of mortar bags; limiting bosses are longitudinally arranged on the base plate at intervals, limiting through holes corresponding to the limiting bosses are formed in the prefabricated track plate and the adjustable mortar layer bag, and the limiting bosses of the base plate are inserted into the limiting through holes of the prefabricated track plate and the adjustable mortar layer bag. When the off-line foundation has large settlement deformation, the rail surface elevation is adjusted and recovered by lifting the rail plate and pouring the quick-setting mortar into the reserved adjustable mortar layer bag, so that the adjusting capacity and the adaptability to the deformation of the off-line foundation are obviously improved.
本发明涉及一种适用于基础变形风险较大区域的可调板式无砟轨道。现有无砟轨道一旦成型难以调整,当线下基础有较大变形时，一般采用线下基础局部切割等方式进行调整，实施难度大。本发明包括底座板，底座板上方设置有预制轨道板，预制轨道板与底座板之间设置有可调式砂浆层袋，包括至少两层砂浆袋；所述底座板上纵向间隔布置有限位凸台，预制轨道板和可调式砂浆层袋上均设置有对应限位凸台的限位通孔，底座板的限位凸台插入预制轨道板和可调式砂浆层袋的限位通孔中。当线下基础发生较大沉降变形后，本发明通过抬高轨道板并向预留可调式砂浆层袋灌注速凝砂浆调整恢复轨面标高，明显提高了调整能力和对线下基础变形的适应性。
