Abstract: A deformation preventing apparatus for constructing an expansion joint of a concrete pavement road can maintain expansion pressure applied to both sides of a cutting portion during a process of cutting the concrete pavement road so that a cutting process is smoothly maintained, thereby forming the expansion joint. The deformation preventing apparatus for constructing an expansion joint of a concrete pavement road includes: an insertion plate made of a metal material and inserted into a cutting gap generated when the concrete pavement road is cut; and a wedge plate made of the metal material and forcedly inserted into the cutting gap in a state in surface-contact with the insertion plate, wherein a surface in which the insertion plate and the wedge plate come in contact with each other forms inclined surfaces pushing each other while the wedge plate is deeply inserted into the cutting gap. Therefore, the deformation preventing apparatus for constructing an expansion joint of a concrete pavement road can prevent a cutting blade of a road cutter from being compressed and stuck by the expansion pressure applied to one side cut road and the other side cut road when the expansion joint is constructed on the concrete pavement road and provide an environment in which the construction of the expansion joint can be continuously and smoothly performed. Also, the deformation preventing apparatus for constructing an expansion joint of a concrete pavement road can prevent a situation in which the cutting blade is stuck and a part of the road must be damaged from being generated and quickly construct the expansion joint without damage to the road, relatively.
