PURPOSE: A mold for the cavity of a tunnel is provided to improve environmentally-friendly effects because a surface treatment work is not required. CONSTITUTION: A mold for the cavity of a tunnel is formed by detachably coupling multiple prefabricated panels(10) made of a synthetic resin material to each other. A lifting jack having an adjustable height is coupled to the bottom of each prefabricated panel using a welding work or bolts and nuts. Multiple angles for reinforcing strength are attached to the rear surfaces of the prefabricated panels in a latticed shape.
