The invention discloses a moveable explosion door for civil air-defense construction. The moveable explosion door comprises at least two door planks, a door frame and a slide slot rack, wherein the door frame is welded with the slide slot rack and is fixed on a concrete wall; the door planks are slidably arranged in the slide slots in the slide slot rack through slide blocks; connecting rod locking mechanisms which are used for locking the door planks on the door frame are arranged on the door planks; buffering strips, which can buffer and prevent collision, are arranged at contact edges of the two door planks; the peripheries of the door planks as well as the door plank and the door plank are all locked through the connecting rod locking mechanisms; stopping blocks for limiting the door planks from continuing to move are arranged at the corners of the door frame and the slide slot rack. The invention aims to provide the moveable explosion door for civil air-defense construction, which has a simple structure, is low in cost, is high in strength and can bear the impact force of about 0.8MPa; the explosion door is capable of horizontally moving; the phenomenon that the door body is tightly blocked and people cannot open can be avoided; the explosion door can be applied to the area in larger pore diameter and is wide in application scope.
