After the soil layer becomes soft, the spiral drill bit 41 drills down into the soil layer, so that the red expansion ball 211 expands, and a patrol worker can find that the soil layer becomes soft at the first time after seeing the expansion ball 211 expands when passing by, thereby reinforcing the soil layer at the first time, avoiding dangerous situations and warning passing people.

The working principle or the using method is as follows:

in the initial state, the covering net 2 is paved on the side slope, the rivets 1 are nailed downwards into the side slope, in the nailing process, the sliding ring 23 is propped against the surface of the side slope, as the shell 21 goes deep into the soil layer of the side slope, the sliding ring 23 slides upwards relative to the shell 21, so that one end of the flexible metal plate 224 in the first sliding groove 221 is driven to move upwards, one end of the flexible metal plate 224 in the second sliding groove 222 is driven to move downwards, one end of the flexible metal plate 224 in the first sliding groove 221 is driven to move upwards, the guiding sliding groove 22 extending into the soil layer is blocked by the flexible metal plate 224 from entering the second sliding groove 222, one end of the flexible metal plate 224 in the second sliding groove 222 is driven to move downwards, one end of the pulling rope 225 is driven to move downwards, the pulling rope 225 wound on the wire wheel 31 is pulled out, the wire wheel 31 is driven to rotate, simultaneously, the second gear 322 is driven to rotate, at the moment, the spiral spring 321 and the second gear 322 are connected together through a clutch under the action of the first elastic piece 25, so that the second gear 322 rotates to drive the rotating block 323 to rotate, the spiral spring 321 is stirred to be full of elastic potential energy, in the process of upward movement of the sliding ring 23, the spiral spring 321 is always in a force accumulation state because the spiral spring 321 and the second gear 322 are always connected together in a clutch manner, when the sliding ring 23 moves upwards to be close to the highest point, namely, when the rivet 1 is about to be completely nailed into a soil layer, the sliding ring 23 is propped against the unlocking piece 33 to drive the unlocking piece 33 to move upwards together, the unlocking piece 33 is propped against the second gear 322 to drive the second gear 322 to move upwards together, and when the sliding ring 23 is propped against the upper end face of the shell 21, the clutch concave block 3211 on the second gear 322 is disconnected from the clutch convex block 3231 on the rotating block 323, at this time, the spiral spring 321 is unlocked, and the rotating block 323 can reversely drive the guide piston rod 413 to rotate.

The rotating block 323 is connected with the guide piston rod 413 in a unidirectional rotation way, so that the spiral drill bit 41 is kept motionless in the process of stirring the spiral spring 321, the rotating block 323 and the guide piston rod 413 rotate relatively, the spiral spring 321 releases potential energy, and the rotating block 323 can drive the guide piston rod 413 to rotate together after reversing.

At this time, the rivet 1 is completely fixed on the soil layer of the side slope, meanwhile, the soil layer at this time is relatively compact, the torsion force provided by the spiral spring 321 is insufficient to enable the spiral drill bit 41 to rotate and extend downwards, the soil layer of the side slope is eroded by rainwater for a long time, the soil layer becomes soft, at this time, the side slope becomes extremely easy to slide, and the resistance to the downward drilling of the spiral drill bit 41 is also reduced in the process of the soil layer becoming soft, so that the spiral spring 321 can drive the spiral drill bit 41 to drill downwards in the process of the soil layer side softening, the spiral drill bit 41 rotates and moves downwards, the spiral blade 411 at the lower end of the spiral drill bit leaves the bottom end of the shell 21, the top contact force of the extension piece 4112 at the lower end disappears, and extends outwards to be pricked into the soil layer, so that the spiral drill bit can be more firmly fixed in the soil layer, meanwhile, the section of the spiral blade 411 can be enlarged, the downward force can be increased in the process of rotating, the spiral blade 411 can be more effectively drilled downwards, the rivet 1 can not be ejected upwards, the side slope can be fixed on the side slope, and the side slope can be fixed on the side slope for a longer time according to the change of the resistance.

In the process of the spiral drill bit 41 being drilled into the soil layer downwards, gas in the spiral rod 412 can enter the expansion ball 211 through the first channel 4132, so that the red expansion ball 211 is inflated and expanded upwards, and a patrol person can find out that the soil layer becomes soft at the first time after the expansion ball 211 is inflated when passing by, thereby reinforcing the soil layer at the first time, avoiding dangerous situations and warning passing persons.
