[0028] By docking multiple docking blocks 3 and connecting blocks 2, the connection and fixation between multiple anti-collapse baffles 1 are achieved, and then the anti-collapse baffle 1 is fitted with the side wall of the foundation pit, so that the entire side wall of the foundation pit can be supported and protected to prevent the side wall of the foundation pit from collapsing. At the same time, multiple protective covers 4 are plugged into the plug-in slot 16 through the telescopic plate 9, and then the U-shaped plate 6 in the protective cover 4 is pulled out from the protective cover 4 and plugged into the connecting slot 5, thereby achieving the connection between multiple protective covers 4. The whole process makes the overall length and width of the protection device adjustable, the splicing is fast, the disassembly is simple, and it is easy to carry. Even if collapse occurs, the protective cover 4 can protect the tunnel and construction personnel, and the pressure sensor 7 on the top of the protective cover 4 will sense the gravity of the soil cover. When the gravity exceeds the set value, it will directly control the alarm light 11 to sound an alarm to remind the construction personnel to escape.

[0029] The reinforcement mechanism includes a moving plate 12 and a pressing plate 13 . The pressing plate 13 is fixedly disposed on one side of the moving plate 12 , a scraper 15 is fixedly disposed on the bottom of the moving plate 12 , and a plurality of fixing nails 14 are disposed on both sides of the moving plate 12 .

[0030] By pulling the pressure plate 13, the pressure plate 13 drives the movable plate 12 to move down along the slide groove. During the downward movement of the movable plate 12, the shovel blade 15 is driven to cut the soil on the inner wall of the foundation pit, so that the shovel blade 15 is always located at the bottom of the foundation pit, which can achieve a supporting effect and prevent the risk of scratching the shovel blade 15, and at the same time the depth of the foundation pit can be adjusted.

[0031] One end of the fixing nail 14 penetrates the surface of the anti-collapse baffle 1 , and a matching slide groove is provided at the connection between the movable plate 12 and the anti-collapse baffle 1 .

[0039] Working principle: when in use, first fit the anti-collapse baffle 1 to the side wall of the foundation pit, then penetrate the fixing nails 14 through the side wall of the foundation pit to fix the anti-collapse baffle 1 to the side wall of the foundation pit, and at the same time, according to the length of the foundation pit, dock multiple docking blocks 3 and connecting blocks 2, fix them with matching fixing bolts, and repeat the above actions to fix the anti-collapse baffle 1 to the side wall of the foundation pit, so that the entire side wall of the foundation pit can be supported and protected to prevent the side wall of the foundation pit from collapsing; at the same time, according to the width between the two anti-collapse baffles 1, pull the telescopic plate 9, and then plug and fix one end of the telescopic plate 9 with the plug-in groove 16, so that the protective cover 4 is fixed above the anti-collapse baffle 1, which can protect the tunnel and construction personnel, and at the same time pull the pull mouth 17 to pull the U-shaped plate 6 out of the protective cover 4, and then plug it into the connecting groove 5. The gap between the two protective covers 4 can also be blocked to prevent soil from entering through the gap during collapse, causing certain dangers to the construction workers; finally, when the foundation pit continues to be dug deeper, the pressure plate 13 is pulled to make the pressure plate 13 drive the movable plate 12 to move down along the slide slot. During the downward movement of the movable plate 12, the shovel blade 15 will be driven to cut the soil on the inner wall of the foundation pit, so that the shovel blade 15 is always located at the bottom of the foundation pit, which can not only achieve the supporting effect, but also prevent the risk of scratches by the shovel blade 15; when encountering collapse, the pressure sensor 7 on the top of the protective cover 4 will sense the gravity of the soil cover. When the gravity exceeds the set value, it will directly control the alarm light 11 to sound an alarm to remind the construction workers to escape, and the protective cover 4 can also protect the tunnel and construction workers, which can extend the escape time for the construction workers.
