The invention particularly relates to an adjustable type ballastless track self-compacting concrete filled combined template and solves the problems that the precision is relatively bad, the filling quality is bad, the wastes are serious and the cleaning consumes a lot of time when self-compacting concrete is poured by an existing template. According to the invention, a pressing plate is fixed on the outer end face of a template body and a connection end plate is fixed on the outer end face of the template body; a bolt connection hole is formed in the connection end plate; a pressing plate I is fixed on the outer end face of a template body I and a connection end plate I is fixed on the outer end face of the template body I; a bolt connection hole I is formed in the connection end plate I; a cam-shaped pressing disc is arranged on the outer end face of the template body I; a pressurizing elbow is additionally arranged outside an exhausting opening formed by an arc-shaped template body and a vertical template body; a concrete discharging opening is formed in the horizontal bottom section of the pressurizing elbow; a connection end plate II is fixed on the outer surface of the arc-shaped template body; a connection end plate III is fixed on the outer surface of the vertical template body. The adjustable type ballastless track self-compacting concrete filled combined template has the advantages of portability, durability, flexibility, waste reduction and cost conservation.
