[0034] Working principle: Before the construction of permanent slope protection works, temporary support is required for the slope. The construction workers use this device to temporarily support the slope. First, the device needs to be installed. During installation, the construction workers first install the installation base 1 on the ground through the ground nails 8, and then splice the adjacent installation bases 1. During splicing, one installation base 1 needs to be connected to another adjacent installation base 1. First, the connecting slide column 4 on the installation base 1 on the right is inserted into the corresponding slide port 7 on the installation base 1 on the left. Then the construction workers install the installation base 1 on the right. The connecting screw 11 on the seat 1 is inserted into the corresponding connecting seat 9 on another mounting base 1, and then the turntable 12 is rotated. The rotation of the turntable 12 drives the connecting screw 11 to rotate, so that the connecting screw 11 is connected to the internal thread of the connecting seat 9, so that the adjacent road construction slope protection devices are spliced ​​together to form a whole. Then, according to the construction needs, several road construction slope protection devices are spliced ​​in turn in the above manner to form a whole, and then the upper slope protection plates 65 and the lower slope protection plates 64 on several mounting bases 1 are in contact with the slope, thereby providing auxiliary support for the slope.

[0035] When the slope protection board on the slope protection device is not in line with the slope, the construction personnel rotate the rotating head 57 by means of a tool, and the rotating head 57 rotates to drive the screw rod 52 connected thereto to rotate, and the screw rod 52 rotates to drive the sliding support seat 53 to move forward and backward under the limiting action of the guide rail 51. When the sliding support seat 53 moves backward, the sliding support seat 53 generates a thrust along the direction of the connecting rod 55 on the connecting rod 55, and the connecting rod 55 pushes the support frame 3 to swing backward with the connection point with the rotating support seat 2 as the center of the circle. , thereby increasing the inclination angle between the slope support frame 6 and the mounting base 1. When the sliding support seat 53 moves forward, the sliding support seat 53 exerts a pulling force on the connecting rod 55 along the direction of the connecting rod 55. The connecting rod 55 pulls the support frame 3 to make a forward swinging motion with the connection with the rotating support seat 2 as the center of the circle, thereby decreasing the inclination angle between the slope support frame 6 and the mounting base 1. The inclination angle between the slope support frame 6 and the mounting base 1 can be adjusted to adapt to slopes of different inclinations.

[0036] When the height of the slope guardrail is too low and cannot adapt to the height of the slope, the construction personnel remove the locking bolt 66 with a tool to release the telescopic lock of the telescopic rod, and then the construction personnel pull the supporting beam 63 upward. The upward movement of the supporting beam 63 drives the expansion support rod 62 to slide inside the branch pipe 61, so that the telescopic rod is adjusted in height up and down, and the supporting beam 63 drives the upper slope guardrail 65 upward to slide inside the lower slope guardrail 64, so that the slope support telescopic plate is unfolded. When the height is adjusted to the appropriate position, the construction personnel reinsert the locking bolt 66 into the socket and thread it with the locking hole 67 adjacent to the socket, thereby completing the telescopic lock of the telescopic rod. The height of the slope guardrail can be adjusted to adapt to slopes of different heights.
