Referring to Fig. 2 and Fig. 3, the inner panel 12 and the outer panel 11 are supported by several support plates 14, the length of the support plates 14 is consistent with the height of the baffle plate 1, and the interlayer space 13 is divided into several by the support plates 14 fixedly connected. The drainage channel 131, the length direction of the drainage channel 131 is consistent with the height direction of the baffle plate 1, the cross-sectional shape of the drainage channel 131 is a regular hexagon so that the section of the interlayer space 13 perpendicular to the length direction of the drainage channel 131 is honeycomb-shaped, each The supporting plates 14 are pierced with communicating holes 141 , and there are three communicating holes 141 on each supporting plate 14 , which are evenly distributed along the length direction of the supporting plates 14 . Adjacent drainage channels 131 are communicated through the communicating holes 141 .

The inner plate 12 and the outer plate 11 are rectangular plates, and the four corners of the inner plate 12 and the outer plate 11 are penetrated by the threaded fasteners 3 to be fixedly connected.

The end of the drain pipe 2 passing through the inner plate 12 is located outside the slope. Nuts 25 are also threaded through the end of the inner plate 12, and the nuts 25 are pressed against the block 26 so that the block 26 is pressed against the surface of the inner plate 12 away from the side slope so that the inner plate 12 is close to the side slope. The slope and the pressing block 26 clamp the inner panel 12 so that the inner panel 12 and the drain pipe 2 are fixed.
