RESEARCH ON THE CONSTRUCTION TECHNOLOGY OF THE WALL ENTRANCE OF THE EXISTING SUBWAY STRUCTURE
Due to the use requirements,no interface is reserved for the exterior wall of the subway designed for the location of the connecting port,which may cause large structural deformation and affect the structural safety when the existing subway wall is cut out.As the reserved interface of the subway cannot be adapted to the connecting port designed by the project,the opening of the connecting port needs to be constructed on the exterior wall of the original subway.It is easy to cause the deformation of the original structure in the construction process and affect the operation of the subway.Therefore,this study first introduces the general situation of the project,expounds the content of the subway opening design,and on this basis,analyzes the subway construction technology and waterproof practice,which provides experience for future engineers and technicians to study the construction technology of the existing structure opening of the subway.
