Water conservancy pipeline supporting and connecting structure for water conservancy project

The water conservancy pipeline supporting and connecting structure comprises a limiting frame, threaded rods are arranged in the centers of the upper side wall, the lower side wall, the left side wall and the right side wall of the limiting frame, one end of each threaded rod extends into the limiting frame, and the other end of each threaded rod extends into the limiting frame. The other end of the threaded rod extends to the outside of the limiting frame, the end, extending to the outside of the limiting frame, of the threaded rod is fixedly connected with a rotating valve, the end, extending to the inside of the limiting frame, of the threaded rod is rotationally connected with an abutting plate, and a supporting component is arranged at the bottom of the limiting frame. By arranging the limiting frame, the threaded rod, the rotating valve, the abutting plate and the like, the supporting device has the advantage of being capable of supporting pipelines with different diameters, and the problem that an exis
