Problems to be Solved by the Invention Conventional connection means of a box culvert are connected by inserting and embedding concave and convex portions and bolting a flange, or by a tension connection using a Pc steel rod or a steel wire. However, in order to prevent water leakage, all of these connecting means must use seals and packings, or must be carefully packed from inside and outside, so it is time-consuming and requires additional measures. However, there is a problem that it is not possible to cope with an unexpected accident such as uneven settlement because the cross section of the product member is used.
