Claims

[Scope of utility model registration request]

An annular continuous plate-shaped mounting part fixed to one of the opposing end walls of adjacent culverts with a fastener such as an anchor bolt, and a plate-shaped mounting part that is continuous in an annular shape and slopes from the outer periphery of the mounting part to the opposite culvert side. An outer seal portion extending toward the outer circumference, and an inner seal portion integrally connected to the outer seal portion on the inner circumference side of the outer circumference seal portion and extending toward the inner circumference while being inclined toward the opposing culvert side. The space in which each seal part can be deformed when the end wall surface of the underdrain and each seal part are crimped is made larger on the outer circumferential side than on the inner circumferential side of the connection base between the outer circumferential seal part and the inner circumferential seal part. Features: Underdrain joints made of elastic materials such as rubber and synthetic resin.
