[0021] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0022] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0023] like Figures 1-7 As shown, this embodiment provides a slope protection structure, including: a barrier component, which includes a frame and a net 500. Multiple frames are arranged at intervals on the slope 100. Specifically, they can be installed near the bottom of the slope 100. This makes construction more convenient, eliminating the need for or minimizing the need for high scaffolding; secondly, it provides a wider protection range, allowing all falling debris above the barrier component to enter its area. The net 500 is detachably connected to adjacent frames, forming a continuous barrier area. The frame includes a connecting section 220 and a buffer section 200. The connecting section 220 connects to the slope 100, and the buffer section 200 is arc-shaped, allowing falling debris to move along the buffer section 200 in a direction away from gravity to mitigate impact. Specifically, the net body 500 is arranged to fit the inner side of the frame, so that the direction and curvature of the net body 500 are roughly the same as those of the frame. This means that whether the rolling object travels directly onto the frame or onto the net body 500, it will move along the arc-shaped path of the buffer section 200, thereby reducing the kinetic energy of the rolling object.

[0024] In some embodiments, the buffer section 200 and the connecting section 220 of the frame are smoothly connected, making it easier for rolling debris to enter the frame. The connecting section 220 is fitted to the slope 100 and has connecting structures. These connecting structures can be holes for bolts or other mechanical connection methods such as fixing lugs 224, and the connecting section 220 is fixed to the slope 100 by anchors 221. Specifically, the connecting section 220 extends vertically downward along the surface of the slope 100, and the buffer section 200 bends upward from the bottom end of the connecting section 220. The angle between the tangent at the top of the buffer section 200 and the horizontal line is an acute angle. The buffer section 200 coincides with the edge of a circle, and the radius of the circle is equal to the radius of the buffer section 200.

[0025] In some embodiments, the anchor 221 can be an anchor cable or an anchor rod, which is exposed from the slope 100 and connected to the framework. Specifically, the outer end of the anchor rod is provided with external threads, and the outer end of the anchor rod is passed through the connecting section 220 of the framework and fixed by a nut. Or the outer end of the anchor cable is fixed with a threaded connector, and the connector is passed through the connecting section 220 and fixed. Further, a connecting base can be cast on the slope 100, and a threaded rod is embedded in the base and connected to the connecting section 220.

[0026] In some embodiments, a support member 300 is provided, which is fixed to the slope 100 at one end and supported on the outside of the framework at the other end. The support member 300 can strengthen the strength of the framework, further increase the firmness of the framework, and avoid the framework from being broken by impact. The support member 300 can be a rigid support column, such as a concrete column, a steel column or a wooden column. It can also be a hydraulic rod that can further absorb impact, and the two ends of the hydraulic rod are respectively hinged to the framework and the slope 100, so that the hydraulic rod shortens to absorb energy when impacted. When installing the support member 300, a base is provided below the slope 100 corresponding to the framework, which can be a cast-in-place concrete pier, and an angle iron 400 is fixed on the concrete pier, so that the lower end of the support member 300 can abut against the flange of the angle iron 400. The steel column can be directly welded with the angle iron 400, and a sleeve for inserting and fixing the wooden pile can also be welded on the angle iron 400.

[0027] Referring to Figures 3-4 In some embodiments, the buffer section 200 can be formed by stacking a plurality of arc-shaped pieces 201, which can be equal in length, and the thickness of the buffer section 200 is the sum of the thicknesses of the plurality of arc-shaped pieces 201. The plurality of arc-shaped pieces 201 can be fixed together or fixed by a U-shaped screw rod. Figure 4 Further, the arc-shaped pieces 201 can also be of different lengths, and the lengths of the plurality of arc-shaped pieces 201 gradually decrease from the inside to the outside. The thickness of the buffer section 200 decreases in a stepped manner from the connecting section 220 to the top end. The plurality of arc-shaped pieces 201 can increase the toughness of the buffer section 200, and have greater elastic deformation capacity than the buffer section 200 of a single-piece structure when impacted, thereby avoiding being broken. In addition, the mutual friction between the arc-shaped pieces 201 can further consume energy.

[0028] In some embodiments, a plurality of sliders 520 are arranged equidistantly on both sides of the net body 500, and a fixing groove 210 is arranged on the inner side of the skeleton, the opening 211 of the fixing groove 210 faces both sides, the width of the opening 211 is slightly larger than the thickness of the net body 500, and the width of the fixing groove 210 is larger than the width of the slider 520. During installation, the net body 500 is slid into the fixing groove 210 from the top end until the bottom end of the net body 500 slides to the bottom end of the fixing groove 210, and the top end of the net body 500 is located at the top end of the fixing groove 210. In order to further increase the stability of the net body 500, a fixing bolt 212 is arranged at the top end and the bottom end of the fixing groove 210, and a through hole 521 is arranged on the slider 520 at the top end and the bottom end of the net body 500 for the fixing bolt 212 to pass through. The two ends of the net body 500 can be fixed on the fixing groove 210 by the fixing bolt 212, so as to keep the net body 500 in an open state. The fixing bolt 212 passes through the through hole 521 of the slider 520 and is screwed to the fixing groove 210.

[0029] In some embodiments, an energy absorbing member 510 is arranged between the net body 500 and the skeleton. The energy absorbing member 510 can be a combination of a spring and a hydraulic damping rod, specifically, the spring is sleeved outside the hydraulic damping rod. It can also be a single spring. When impacted, the energy absorbing member 510 can absorb part of the impact force to reduce the stress on the net body 500 or the connection part between the net body 500 and the skeleton.

[0030] Referring to Figure 7 In some embodiments, the buffer section 200 and the connecting section 220 are rotationally connected, and the bottom end of the buffer section 200 is hinged to a position close to the bottom of the connecting section 220. A positioning seat 222 is arranged at the bottom end of the connecting section 220, and an inclined surface 223 is arranged on the side of the positioning seat 222 facing the buffer section 200, and a safety rod 225 is further arranged between the inclined surface 223 and the buffer section 200, which supports the buffer section 200 so that the buffer section 200 remains in the current position and does not continue to rotate downward. When impacted by external force, the safety rod 225 will bear part of the force, and when the pressure borne by the safety rod 225 is greater than its limit value, the safety rod 225 will deform or break until the buffer section 200 rotates to the inclined surface 223. When the safety rod 225 breaks or cannot continue to be used, it can be replaced. Specifically, a pair of support ears are arranged on the positioning seat 222, which are arranged on both sides of the buffer section 200, and the safety rod 225 is fixed on the support ears to support the buffer section 200. The positioning notches extending downward can be formed on the two fixing ears 224, and the two ends of the safety rod 225 are lapped into the positioning notches. The energy shared by the safety rod 225 can further reduce the impact force on the net body 500.

[0031] When encountering the rolling object, the net body 500 and the framework can block the rolling object to avoid the rolling object continuing to move downward. When the net body 500 traps the rolling object, the hidden danger needs to be removed immediately, and the space for subsequent interception needs to be cleared. The removed rolling object needs to be removed from the framework. Further, a processing platform can be constructed below the corresponding framework on the slope 100, so that the trapped rolling object rolls into the processing platform after the corresponding net body 500 is removed, facilitating subsequent transfer processing. Then the net body 500 can be reinstalled. If the net body 500 is damaged, only the damaged net body 500 needs to be removed and a new net body 500 needs to be reinstalled. All net bodies 500 do not need to be replaced, and the operation is more convenient.
