[0021] In order to explain in detail the technical content and structural features of the reinforced connection device for the outdoor drainage pipe joint of the utility model, further explanation is given below in combination with the implementation method and the accompanying drawings.
[0022] like Figure 1 , 2 As shown in Figures 3, 4 and 5, the utility model is a reinforced connection device for outdoor drainage pipe joints, including a connecting hoop 5, a U-shaped tray 13 and a tensioning assembly. The connecting hoop 5 is arranged at the adjacent drainage pipe joint 6, and the connecting hoop 5 connects the adjacent drainage pipes 11 together. The U-shaped tray 13 is arranged at the bottom of the adjacent drainage pipes 11. The U-shaped tray 13 is cut from galvanized steel pipe. The length of the U-shaped tray 13 extending into the drainage pipes at both ends is not less than 100 mm. The U-shaped tray 13 is supported on the outside of the connecting hoop 5 and the drainage pipe 11.
