Description

Prefabricated assembled subway station lining structure connects Technical Field The invention relates to the field of tunnel construction, in particular to a prefabricated subway station lining structure joint. Background Currently, the problem of water seepage is prevalent in subway stations, in particular prefabricated stations. Water seepage mainly occurs at various joints or contact interfaces, because these places are structural waterproof weak points, and the integrity is poor. It can be said that the water seepage problem is a great technical difficulty affecting the development of the prefabricated building mode of the subway station. The traditional waterproof method of subway stations is to fill various waterproof materials such as water stops at joints to block water seepage channels. In recent years, students have proposed some new waterproof measures for prolonging the water seepage path, and if a reliable connection mode can be proposed, connection of the prefabricated lining structure is facilitated. Disclosure of Invention The invention aims at solving the water seepage problem of a subway station, and provides a prefabricated lining structure joint for the subway station, which is designed by mortise and tenon connection of the prefabricated lining structure joint and is combined with a one-way locking structure formed by matching a water stop and a groove. The invention comprises a tenon end of a prefabricated lining structure and a mortise end of the prefabricated lining structure; The tenon end of the prefabricated lining structure comprises a water stop and a tenon end connecting portion, the water stop is fixedly connected to the end of the tenon end connecting portion, the water stop and the tenon end connecting portion form a stepped bulge, the mortise end of the prefabricated lining structure is provided with a water stop mounting groove and a mortise end connecting portion, and the water stop mounting groove and the mortise end connecting portion form a stepped through groove, so that tenon-and-mortise connection is achieved after the tenon end of the prefabricated lining structure is embedded into the mortise end of the prefabricated lining structure. As a preferable mode of the invention, the sections of the water stop mounting groove and the mortise end connecting part are trapezoidal, the section upper bottom of the mortise end connecting part coincides with the section lower bottom of the water stop mounting groove, the section lower bottom of the water stop mounting groove is longer than the section upper bottom of the mortise end connecting part, so that the sections of the water stop mounting groove and the mortise end connecting part are stepped sections, the sections of the water stop and the mortise end connecting part are trapezoidal, the section lower bottom of the water stop is fixedly connected with the section upper bottom of the tenon end connecting part, and the section lower bottom of the water stop is longer than the section upper bottom of the tenon end connecting part, so that the sections of the water stop and the tenon end connecting part are stepped sections.
