[0022] The through holes 32 provided inside the lower anti-seepage plate 31 facilitate air from the outside to flow into the lower anti-seepage plate 31 through the through holes 32, thereby enabling the lower anti-seepage plate 31 to always remain dry, and moisture seeping from underground can be discharged into the drainage ditch 2 through the through holes 32, so that no water will accumulate inside the lower anti-seepage plate 31.
[0023] In the specific implementation process, Figure 1 , Figure 2 and Figure 3 As shown, the upper anti-seepage plate 41 is mounted on the surface of the lower anti-seepage plate 31 by being clamped in the positioning groove 33 through the clamping groove 44, and the waterproof membrane 42 is spaced between the upper anti-seepage plate 41 and the lower anti-seepage plate 31, and the waterproof membrane 42 is tightly fixed to the surface of the clamping groove 44, and a gap is provided between the clamping groove 44 and the positioning groove 33.
