Zusammenfassung:A prefabricated arch tunnel with a T-shaped section is provided to prevent the contact support part from being damaged by forming the S-shaped section of the contact support part contacting the ceiling and side wall members. A prefabricated arch tunnel with a T-shaped section comprises a pair of side wall members(20); and a ceiling member(30) whose both ends are supported at upper and lower parts of the side wall member. The ceiling member has an arch shape upwardly curved, and a supporting beam(34) is projected at the lower surface of the ceiling member. The section of the ceiling member is T-shaped. The side wall member is formed with a contact support part(22) at the upper end to contact-support the ceiling member, and the contact support part has an S-shaped section.
