The present invention relates to a waterproof expansion joint device for facilities including a sewage culvert. The waterproof expansion joint device for facilities including a sewage culvert is installed with a long rectangular bar-shaped elastic rubber or foam rubber at the top and bottom openings of a space between the first and second forms as separating plates; and a plurality of anchor bolts, re-bars, dowel bars, and dowel bar caps to be symmetric to each other at predetermined gaps on the outer surface of the first and second forms. The first and second forms are shaped into a plate to be suitable for rectangular plates or concrete structures which are in parallel to each other in a vertical direction at a predetermined distance between the concrete structures. The waterproof expansion joint device for facilities including a sewage culvert is also installed with a plurality of forms functioning as fasteners at predetermined intervals between the first and second forms as separating plates in order to enable workers to adjust the distance between the first and second forms as separating plates and to prevent the escape of the elastic rubber or foam rubber. Therefore, the waterproof expansion joint device for facilities including a sewage culvert significantly improves the constructability, quality, and waterproof properties of the facilities by accurately setting the distance between the expansion joints using the forms as the separating plates at both sides to fasten the waterproof expansion joint device; using a composite material by embedding partially an expansive rubber strip into both sides of the elastic rubber or the foam rubber as necessary to be openable; or attaching a rubber escape preventive piece to the top and bottom of the form as the separating plate and forming a catching groove on the top of the elastic rubber or the foam rubber. |
