[0027] The working principle and use process of the present invention are as follows: when in use, the blocking structure is placed at the position where blocking is required, and then the anti-skid screw 28 is loosened, and then the adjustable metal slide plate 27 is adjusted to make the anti-dumping limit support plate 22 contact the ground, and then the anti-skid screw 28 is tightened, and then the driving screw 292 is turned to move the adjustable anti-skid fixing plate 21 downward, so that the adjustable anti-skid fixing plate 21 is inserted into the ground, thereby achieving reliable anti-skid fixation of the blocking structure, and then the adjustable sealing airbag 72 is inflated by the adjustable air pump 61 to make the adjustable sealing airbag 72 inflated and expanded, thereby achieving complete blocking of the lane, and making the blocking effect of the blocking structure better; When the tunnel is larger than the blocking structure, the blocking structure is adjusted to suitability. At this time, the first telescopic position adjusting member 64 is controlled to extend so that the adjustable sealing airbag 72 on the side of the movable blocking baffle 63 contacts the side wall of the tunnel. Then, the second telescopic position adjusting member 75 is controlled to extend so that the top of the adjustable sealing airbag 72 contacts the tunnel. Then, the fourth telescopic position adjusting member 79 is controlled to extend so that the adjustable sealing airbag 72 on the adjustable metal support plate 71 contacts the inner wall of the tunnel. The curvature of the adjustable metal support plate 71 is adjusted so that the adjustable sealing airbag 72 can better fit the curved top of the laneway, and the adjustable metal support plate 71 always keeps in contact with the limit blocking baffle 1 during the adjustment process, thereby completing the adjustment of the size of the blocking structure.

Secondly, the present invention has an anti-slip fixing function, thereby effectively improving the reliability of the blocking structure. In addition, the present invention has an information display function, which makes the functions of the blocking structure more abundant. In addition, the present invention has a simple structure, is easy to use, and is worthy of promotion and use.
