It should be understood that the description in the form of a range is only for convenience and brevity, and should not be construed as a rigid limitation on the scope of the present application. Therefore, it should be considered that the described range description has specifically disclosed all possible sub-ranges and single values within that range. For example, it should be considered that the range description from 1 to 6 has specifically disclosed sub-ranges such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., as well as single numbers within that range, such as 1, 2, 3, 4, 5, and 6, regardless of the range.

Additionally, in this application, terms such as "include" and "comprise" mean "include but not limited to". In this application, relative terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. In this application, "and / or" describes the associated relationship of associated objects and indicates that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, or B exists alone. Where A and B can be singular or plural. In this application, "at least one" means one or more, and "multiple" means two or more. "At least one kind", "at least one of the following items", or similar expressions refer to any combination of these items, including any combination of single items or plural items. For example, "at least one of a, b, or c", or "at least one of a, b, and c" can both represent: a, b, c, a - b (i.e., a and b), a - c, b - c, or a - b - c, where a, b, and c can be single or multiple respectively.

[0030] Figure 3 It is the overall structure diagram of the elastic blocking rod of the embodiment of this application.

[0031] As Figures 1 - 3 shown, the embodiment of this application provides a rockfall blocking structure for high - slope protection in high - altitude cold mountainous areas, including:

[0032] An elastic blocking belt, the elastic blocking belt includes a cement - casting layer 1 and a number of elastic blocking rods 2 cast and arranged above the cement - casting layer 1;

[0033] On the side of the cement - casting layer 1 away from the falling rocks, cement columns 3 are also cast at equal intervals, and fixing blocks 4 are cast at the upper ends of the cement columns 3. First sliding rods 5 are fixedly connected to the outsides of the fixing blocks 4. First sliding rings 6 are movably sleeved on the outsides of the first sliding rods 5, and first connecting rods 7 are fixedly connected to the upper ends of the first sliding rings 6;

[0034] A horizontal second sliding rod 8 is also cast between the cement columns 3. Second sliding rings 14 are slidably sleeved on the outsides of the second sliding rods 8, and second connecting rods 11 are fixedly connected to the upper ends of the second sliding rings 14;

[0035] A blocking net 12 is connected between the first connecting rod 7 and the second connecting rod 11.

[0036] Specifically: The cement casting layer 1 is arranged at the bottom of the high slope. When small or large falling rocks fall, they first pass through the buffering and blocking of the elastic blocking rods 2, and the small falling rocks are blocked, while the speed of the large falling rocks is buffered by the elastic blocking rods 2 and then impacts the blocking net 12 and is blocked by the blocking net 12. When the blocking net 12 blocks, the impact force will be buffered by the first buffer spring 13 and the second buffer spring 9, and the blocking net 12 will not be damaged by the impact force of the falling rocks, greatly increasing the service life of the blocking net 12.

[0037] As Figure 1 and Figure 2 shown: The elastic blocking rod 2 includes a fixed bottom rod 22, an elastic rod 21, a plugging rod 23 and a nut 24. The fixed bottom rod 22 is cast in the cement casting layer 1, and the plugging rod 23 is inserted into the middle of the fixed bottom rod 22 through threads. The upper end of the plugging rod 23 is fixedly connected with a nut 24, and the upper end of the nut 24 is fixedly connected with an elastic rod 21.

[0038] Specifically: The nut 24 can facilitate the installation of the plugging rod 23 inserted into the fixed bottom rod 22 through tools.

[0039] As Figure 1 shown: A number of the elastic blocking rods 2 are provided and are arranged chaotically on the upper part of the cement casting layer 1.

[0040] Specifically: The elastic blocking rod 2 can be made of elastic rubber material, which can buffer the impact force of the falling rocks when the falling rocks fall.

[0041] As Figure 1 shown: The end of the first sliding rod 5 away from the fixed block 4 is fixedly connected with a first retaining ring, and a first buffer spring 13 is sleeved on the outer side of the first sliding rod 5 between the first sliding ring 6 and the fixed block 4.

[0042] Specifically: The first buffer spring 13 can buffer the impact force on the upper part of the blocking net 12.

[0043] As Figure 1 shown: The end of the second sliding rod 8 away from the second connecting rod 11 is fixedly connected with a second retaining ring 10, and a second buffer spring 9 is sleeved on the outer side of the second sliding rod 8 between the second retaining ring 10 and the second sliding ring 14.

[0044] Specifically: The second buffer spring 9 can buffer the impact force on the lower part of the blocking net 12.

[0045] As Figure 1As shown: A pouring rod is inserted in the middle of the fixed block 4, and the pouring rod is inserted and poured into the middle of the corresponding cement column 3.

[0046] Specifically: Pouring and setting the fixed block 4 can make the connection of the fixed block 4 more stable and firm.

[0047] As Figure 1 shown: The blocking net 12 covers the fixed block 4 and the first sliding rod 5.

[0048] Specifically: The blocking net 12 uses an existing net for blocking falling rocks on the market.

[0049] As Figure 1 shown: The first connecting rod 7 and the second connecting rod 11 can be made of soft steel wire strips.

[0050] Specifically: The soft steel wire strips are in a buffer state and will not break due to the impact force of falling rocks.

[0051] When the equipment is in use, first pour the cement pouring layer 1. During the pouring process, embed the second sliding rod 8 and the fixed bottom rod 22 inside the cement pouring layer 1. When pouring the cement pouring layer 1, also pour the cement column 3 through a template, and pour the fixed block 4 at the upper end of the cement column 3;

[0052] After the cement pouring layer 1 and the cement column 3 are formed and solidified, install each elastic rod 21, and sleeve the first sliding ring 6 and the second sliding ring 14, and at the same time sleeve the first buffer spring 13 and the second buffer spring 9, and finally connect the blocking net 12;

[0053] When smaller or larger falling rocks fall, they are first buffered and blocked by the elastic blocking rod 2, and the smaller falling rocks are blocked. The speed of the larger falling rocks is buffered by the elastic blocking rod 2 and then impacts the blocking net 12 and is blocked by the blocking net 12. When the blocking net 12 blocks, the impact force will be buffered by the first buffer spring 13 and the second buffer spring 9, and the blocking net 12 will not be damaged by the impact force of the falling rocks, greatly increasing the service life of the blocking net 12.

[0054] The above are only specific embodiments of the present application, enabling those skilled in the art to understand or implement the present application. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined in the present application can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown in the present application, but will conform to the widest scope consistent with the principles and novel features claimed in the present application.
