As the pace of urban construction continues to accelerate,people have new demands for travel modes, not only speed but alsoquality, which has promoted the development of subway civil airdefense projects. The most critical part of the subway civil air defenseproject is the construction technology of the interval door breaking,which is directly related to the overall effect of the subway civil airdefense project construction and the later use effect. Based on this, thispaper explores the construction technology of the interval door of thesubway civil air defense engineering area, in order to provide referencefor the subway civil air defense project construction.
