Drainage pipeline supporting and connecting structure of municipal engineering

The utility model relates to the technical field of municipal engineering construction, in particular to a municipal engineering drainage pipeline supporting and connecting structure which comprises a base. The arc-shaped supporting plate is located on the base, the arc-shaped supporting plate is fixedly welded to the top of the base, baffles are fixedly welded to the two sides of the top of the base, the baffles are movably connected with clamping plates through telescopic rods, and the fixing mechanism comprises a threaded rod, a threaded sleeve, a rotary knob and a limiting rod. According to the drainage pipeline supporting and connecting structure for municipal engineering, due to the arrangement of the fixing mechanism, pipelines of different sizes can be clamped and fixed in the using process, meanwhile, the stability and fastening performance of fixing of the drainage pipeline are guaranteed, the service life of the drainage pipeline is prolonged, and due to the arrangement of the lifting mechanism, th
