Two first hydraulic telescopic rods 801 are provided on the same side. The bottom of the extended ends of the two first hydraulic telescopic rods 801 on the same side are fixedly connected to a reinforcement pad 802. Several L-shaped plates 803 are fixedly connected to the top of the reinforcement pad 802. A frame 804 is fixedly connected to one side of the L-shaped plate 803.

[0031] The advantage of Embodiment 2 compared to Embodiment 1 is that by setting a side plate 15 and a lifting ring 16 on one side of the reinforcing pad 802, the device can be easily matched with the lifting device through the lifting ring 16, which facilitates lifting and transportation.

[0032] The specific usage steps are as follows: Step 1, hoisting and landing: Using hoisting equipment and lifting ring 16, the entire device is laid at an angle on the prepared slope. Step 2, reinforcement of the laying position: By pushing the pusher 18 to adjust the position on the slope, after the fixed point is selected, start the first hydraulic telescopic rod 801. The extension end of the first hydraulic telescopic rod 801 drives the reinforcement pad 802 to descend until the reinforcement pad 802 is in contact with the slope. During the descent of the reinforcement pad 802, the reinforcement pad 802 simultaneously drives the insertion frame 804 to descend through the L-shaped plate 803, causing the insertion frame 804 to insert into the slope. It should be noted that when the insertion frame 804 descends, it simultaneously drives the opening frame 809 to descend through the movable column 805. After the insertion frame 804 is descended, the opening of the opening frame 809 will be on the transverse matching trajectory line of the control pressure plate 811. Step 3, Limiting slide rail deployment: After the device is fixed, start the third electric telescopic rod 704 and the fourth electric telescopic rod 709. The third electric telescopic rod 704 starts its extension end to drive the second toothed plate 705 to move. The second toothed plate 705 moves and meshes with the second gear 703, causing the second rotating shaft 702 to drive the second auxiliary slide plate 701 to rotate 90 degrees and form a longitudinal line with the second main slide plate 602. When the fourth electric telescopic rod 709 is activated, its extension end will drive the first toothed plate 710 to move. The first toothed plate 710 moves and meshes with the first gear 708, causing the first rotating shaft 707 to drive the first auxiliary slide plate 706 to rotate ninety degrees and form a longitudinal axis with the first main slide plate 4. Step 4, Overall Protection Deployment: Activate the second electric telescopic rod 601, causing the extension end of the second electric telescopic rod 601 to drive the second main slide plate 602 to descend. The second main slide plate 602 drives the first slider 603 to descend. The first slider 603 drives the mounting frame 604 to descend. The mounting frame 604 presses down on the inclined slope protection plate 605, causing the slope protection plate 605 to be laid flat downwards and cover the slope surface. Step 5, Slope Adhesion and Pull-out Reinforcement: After several slope protection boards 605 are laid flat, the second hydraulic telescopic rod 810 is activated, causing the extension end of the second hydraulic telescopic rod 810 to pull the central control pressure plate 811 into the interior of several open frames 809. Then the first electric telescopic rod 2 is activated. The extension end of the first electric telescopic rod 2 drives the first main slide plate 4 to descend through the L-shaped frame 3. The first main slide plate 4 drives the slope protection plate 605 in the unfolded state to descend until the slope protection plate 605 is close to the slope surface, reducing the contact gap between the slope protection plate 605 and the slope surface. When the L-shaped frame 3 drives the first main sliding plate 4 to descend, the L-shaped frame 3 simultaneously drives the central control pressure plate 811 to descend. The central control pressure plate 811 drives the opening frame 809 to descend. The opening frame 809 drives the movable column 805 to descend. The movable column 805 descends and presses the push-pull plate 808, causing the horizontal insertion rod 807 to extend from the limiting slot 806 and be inserted horizontally into the soil layer to complete the pull-out reinforcement.
