The drainage structure 200 includes an annular guide plate 202 fitted on the inner wall of the tunnel support body 100, and the annular guide plate 202 can filter and converge the inner wall of the tunnel. To achieve a certain supporting and stabilizing effect, an arc filter plate 203 is arranged on the outer surface of the annular guide plate 202, and the arc filter plate 203 can filter the accumulated water seeping from the inner wall of the tunnel, so that the accumulated water falls on the annular guide plate 202 through the filter holes on the surface of the arc filter plate 203, and the accumulated water flows downward along the annular guide plate 202. A water seepage layer 204 is arranged between the outer surface of the arc filter plate 203 and the tunnel support body 100. The water seepage layer 204 is composed of multiple layers of non-woven fabrics, which increases the filtering effect of the accumulated water on the inner wall of the tunnel and increases the use strength of the water seepage layer 204. A drainage component 201 is arranged at the bottom of the annular guide plate 202, and the drainage component 201 is convenient for collecting and discharging the accumulated water;

[0023] The drainage component 201 includes a drainage plate 2011 embedded and installed at the bottom of the bottom template 101 . The drainage plate 2011 has a U-shaped cross section, which is convenient for collecting the accumulated water left from the annular guide plate 202 .
