[0020] During use, multiple groups of drainage components drain the water in the rock layer on the upper part of the tunnel roof in multiple directions and collect it into the drainage component.

The drain pipe 8 can divert the water flow into the drainage trough 9. At the same time, because the bottom surface of the drainage trough 9 is set with an inclined surface, the water can be diverted and transported to the collection area outside the mine tunnel.
