[0037] As Figure 1 , 4As shown in FIGS. 10, 11, 12, 13 and 14, the filter body 6 comprises a filter plate 61, rubber frames 62, upper fixing blocks 64, lower fixing blocks 65, upper insertion plates 66, lower insertion plates 67 and clamping balls 68. The rubber frames 62 are arranged on the front and back sides of the filter plate 61. An installation groove 63 is arranged on the side of the rubber frame 62 close to the filter plate 61. The rubber frames 62 arranged on the front and back sides of the filter plate 61 are in close contact with each other. Insertion grooves 69 are arranged in the rubber frames 62. The upper insertion plates 66 are arranged in the insertion grooves 69 arranged on the top of the rubber frames 62. The lower insertion plates 67 are arranged in the insertion grooves 69 arranged on the bottom of the rubber frames 62. The two upper insertion plates 66 are fixedly connected to the bottom of the upper fixing block 64. The two lower insertion plates 67 are fixedly connected to the top of the lower fixing block 65. The clamping balls 68 are fixedly connected to the side close to each other of the two upper insertion plates 66 fixedly connected to the bottom of the same upper fixing block 64.

flood prevention groove 22 opened by the road surface body 21, at this time because the water in the tunnel top shell 1 is discharged through the flood prevention groove 22, the water guide groove 23 and the water guide groove 24, therefore the vehicles in the tunnel can continue to pass, after a large amount of impurities block one filter plate 61, the water level on the side of the filter plate 61 blocked gradually rises until the water level exceeds the top of the filter plate 61, at this time the water flows to the side of the next filter plate 61 through the filter plate 61, and the water is filtered through the next filter plate 61, at the same time when there is too much water in the flood prevention groove 22 opened by the road surface body 21, the water flows out, and the next flood prevention groove 22 sends the water into the water guide groove 24 through the water guide groove 23 for discharge, after the flood season ends, the second water plate 5 is directly moved upward, at this time the filter plate 61 and the rubber frame 62 can be taken out from the water guide groove 24 opened by the road surface body 21, then a large amount of impurities accumulated on one side of the filter plate 61 is taken out, the upper fixed block 64 is moved upward, the lower fixed block 65 is moved downward, the upper insertion plate 66 and the lower insertion plate 67 are taken out from the rubber frame 62, at this time the two rubber frames 62 can be taken off from both sides of the filter plate 61, so as to maintain or replace the filter plate 61, then the two rubber frames 62 are installed on both sides of the filter plate 61, the filter plate 61 is arranged in the installation groove 63 opened by the rubber frame 62, the upper insertion plate 66 fixedly connected to the bottom of the upper fixed block 64 is inserted into the insertion slot 69 opened above the two rubber frames 62, at this time the clamping ball 68 pushes the rubber frame 62 to deform, the clamping ball 68 pushes the two rubber frames 62 to tightly fit with each other, at the same time the two upper insertion plates 66 push the rubber frame 62 to tightly fit with the filter plate 61, then the lower insertion plate 67 is inserted into the insertion slot 69 opened at the bottom of the two rubber frames 62, so as to install the rubber frame 62 between the filter plates 61, finally the filter plate 61 is installed in the water guide groove 24 opened by the road surface body 21, the lower fixed block 65 is inserted into the clamping slot 27 opened by the road surface body 21, at the same time the left and right sides of the rubber frame 62 tightly fit with the inner wall of the water guide groove 24 opened by the road surface body 21, then the second water plate 5 is installed above the water guide groove 24 opened by the road surface body 21, when the filter plate 61 is maintained, the worker operates at the position outside the motorway on both sides of the tunnel, at this time the tunnel does not need to be closed, and does not affect the traffic, after a long time of use, the tunnel can be closed, the first water plate 3 is taken out upward for maintenance or replacement,Meanwhile, the bolt 286 is taken out from the inner threaded pipe 287 by rotating the bolt 286 through the tool, then the support base 281 can be moved to drive the insertion rod 283 to be taken out from the road surface body 21, at this time, the support base 281 can be taken down and replaced, and the support base 281 is replaced in time to prevent the support base 281 from being damaged under the action of the pressure, when the replacement is performed, the insertion rod 283 fixedly connected with the new support base 281 is inserted into the insertion pipe 285 through the fixed plate 284, then the bolt 286 is screwed with the inner threaded pipe 287 through the support base 281 and the fixed plate 284 to fix the support base 281, then the new first downcomer plate 3 is placed in the flood-preventing groove 22 of the road surface body 21, the first downcomer plate 3 is supported by the support base 281, so that the vehicle can stably travel on the surface of the road surface body 21.
