A watertight belt for connecting pipes is provided to prevent the contraction of flexible pipes by inserting an internal pipe fixture having a projection on a connection of a flexible pipe and a flexible pipe, to keep water-tightness by making an internal pipe fixture function as a rubber ring, and to keep water-tightness strongly by pushing projections of flexible pipes with a projection of an internal pipe fixture continuously, and pushing a projection of an internal pipe fixture inward with an extension rubber projection of a projection binding plate and widening. A watertight belt for connecting pipes enables to prevent a flexible pipe from being deformed or pressed when the ground is deformed or a weight is put on a connection when connecting a flexible pipe(100) and a flexible pipe(100A) by inserting an internal pipe fixture(200), which is provided with an internal pipe pulling rubber plate on the inside and an extension rubber projection on the outside and used as a connecting ring for connecting a joint of pipes when the flexible pipe and the flexible pipe join, to the inside between the flexible pipe and the flexible pipe, and covering the outside of the flexible pipe and the flexible pipe connected by the internal pipe fixture with a projection binding plate(300) fitted with a rubber extension projection and a central adhesion projection having symmetric angles for gathering the trapezoidal shape of an external reinforcement bar inward around the central adhesion projection, and then covering in a circle with a fastening belt(400), and installing L-shaped fastening bolts compression plates(500) on two sides of the fastening belt and fastening with a hexagonal bolt and a nut for preventing the deflection or deformation of the fastening bolt. |
