[0044] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0045] During the construction of high-speed railways, highways, wind power or water conservancy projects, a large number of high fill slopes will inevitably be generated. Under the action of rainfall scouring and gravity, the earthwork of these high fill slopes will roll or slide down along the slope surface 300, destroying the stability and integrity of the slope surface 300, and then causing large-scale slag sliding on the slope surface 300. The slag sliding phenomenon will not only harm the vegetation, land and water system downstream, but may also lead to the phenomenon of "white mountains", causing serious soil erosion, and affecting the beauty and ecological environment of the slope surface 300.
[0046] In view of this, the anti-slag sliding device provided by the embodiment of the utility model includes a groove 100 and a plurality of temporary interception nets 200 arranged on the slope 300; the groove 100 and the plurality of temporary interception nets 200 are arranged in sequence from top to bottom along the slope 300; each temporary interception net 200 is provided with a plurality of buffer holes 210, and the plurality of buffer holes 210 are arranged in sequence along the length direction and the width direction of the temporary interception net 200; the areas of the buffer holes 210 of the plurality of temporary interception nets 200 decrease in sequence from top to bottom along the slope 300.
[0047] Specifically, see Figure 1 , multiple temporary interception nets 200 are vertically arranged, and the axis of the buffer hole 210 is perpendicular to the extension direction of the groove 100.
[0048] See also Figures 1 to 4 , multiple temporary interception nets 200 are arranged in sequence from top to bottom, and the area of the buffer hole 210 is reduced in sequence, so as to intercept slag bodies of different particle sizes step by step, slow down the slag slip phenomenon, and avoid the problem that a single temporary interception net 200 is easily damaged due to excessive slag bodies. In addition, the temporary interception net 200 can be used temporarily and repeatedly, which has the advantages of economy, convenience and high practicality.
[0049] See also Figure 1 and Figure 5 The groove 100 can drain the rainfall from the slope 300 and buffer the slag generated by the construction above the slope 300, thereby reducing the impact of the slag on the temporary interception net 200 and ensuring the stability of the temporary interception net 200.
[0050] The structure and shape of the slag prevention device are described in detail below:
[0051] In an optional solution of the embodiment of the utility model, the areas and shapes of the multiple buffer holes 210 on a single temporary interception net 200 are the same.
[0052] Specifically, see Figures 2 to 4 The temporary interception net 200 is set in a square shape, with the length direction being set along the extension direction of the groove 100 and the width direction being set along the vertical direction a.
[0053] The areas and shapes of the multiple buffer holes 210 on a single temporary interception net 200 are the same, which is convenient for processing; of course, the areas of the multiple buffer holes 210 on a single temporary interception net 200 are different, but the requirement that the areas of the buffer holes 210 of the multiple temporary interception nets 200 decrease successively from top to bottom along the slope 300 is met. For example, the area of the buffer hole 210 located in the middle position of the single temporary interception net 200 is the largest, and the smaller the area of the buffer holes 210 on both sides of the temporary interception net 200 should also be within the protection scope of the embodiments of the present utility model.
[0054] In an optional solution of the embodiment of the utility model, the shapes of the buffer holes 210 of the multiple temporary interception nets 200 are all the same.
[0055] Specifically, see Figures 2 to 4 The overall sizes of the multiple temporary interception nets 200 are equal, and the areas of the buffer holes 210 of the multiple temporary interception nets 200 decrease successively from top to bottom along the slope 300, and the number of the buffer holes 210 increases successively.
[0056] The shapes of the buffer holes 210 of the multiple temporary interception nets 200 are all the same, which further facilitates processing.
[0057] In an optional solution of the embodiment of the utility model, the buffer hole 210 is set to be square.
[0058] Specifically, see Figures 2 to 4 , in two adjacent temporary interception nets 200, the area of the buffer holes 210 of the temporary interception net 200 located at the upper part of the slope 300 is 4 times the area of the buffer holes 210 of the temporary interception net 200 located at the lower part of the slope 300; of course, in two adjacent temporary interception nets 200, the area of the buffer holes 210 of the temporary interception net 200 located at the upper part of the slope 300 is other multiples of the area of the buffer holes 210 of the temporary interception net 200 located at the lower part of the slope 300, such as 2 times, 3 times or 5 times, etc., which should also be within the protection scope of the embodiments of the present utility model.

[0061] Specifically, see Figure 1 In this embodiment, three temporary interception nets 200 are provided, namely, a first temporary interception net 220, a second temporary interception net 230 and a third temporary interception net 240. Of course, other numbers of temporary interception nets 200, such as two, four or five, should also be within the protection scope of the embodiment of the utility model; the specific number can be set according to the specific conditions of the slope 300.
[0062] The buffer holes 210 of the first temporary interception net 220 are set to 30cm×30cm; the buffer holes 210 of the second temporary interception net 230 are set to 15cm×15cm; the buffer holes 210 of the third temporary interception net 240 are set to 5cm×5cm, so that the areas of the buffer holes 210 of the multiple temporary interception nets 200 decrease successively from top to bottom, thereby achieving step-by-step interception of slag of different particle sizes, slowing down the slag sliding phenomenon, and avoiding the problem of a single temporary interception net 200 being easily damaged due to excessive slag.
[0063] In the optional scheme of the embodiment of the utility model, please see Figure 1 , the distance between the second temporary interception net 230 and the first temporary interception net 220 is equal to the distance between the second temporary interception net 230 and the third temporary interception net 240.

[0065] In an optional solution of the embodiment of the utility model, the temporary interception net 200 includes a protective fence 250; the protective fence 250 has a buffer hole 210.
[0066] Specifically, in this embodiment, the protective fence 250 is woven using bamboo pieces, which are light in weight, tough and easy to obtain, so that the protective fence 250 is light in weight and easy to carry, has good toughness to avoid breakage after impact, and is easy to make.
[0067] The protective fence 250 has a buffer hole 210, which makes the temporary interception net 200 economical, practical and convenient.

[0073] In an optional solution of the embodiment of the present utility model, the slope ratio of the side wall of the groove 100 is set to 1:0.5.
[0074] Specifically, in this embodiment, the width of the bottom wall of the groove 100 is set to 20 cm, and the depth is set to 20 cm.
