Description

Technical Field

[0001] This utility model relates to a snow barrier fence, specifically a suspended snow barrier fence, a snow-blocking facility, and is particularly applicable to the field of snow-blocking facilities for highways or railways. Background Technology

[0002] Blowing snow is a common phenomenon, consisting of snow and wind speeds that propel snow particles. The snow particles are carried by the wind and become blown, forming blowing snow. The presence of blowing snow has a significant impact on linear engineering projects (such as railways and highways). Deposits on railways will affect normal train operations, while accumulation on highways will block roads and disrupt traffic. Therefore, builders or maintenance personnel install snow barriers at considerable distances to block snowflow, causing it to accumulate within a certain area and ensuring the normal operation of railways or highways. Currently used snow barriers are generally made of materials such as steel, concrete slabs, or plastic. Steel and concrete snow barriers are expensive, have complex construction processes, and are difficult to adapt to complex terrain conditions. While plastic-based materials are relatively inexpensive, their durability is poor, they are not adaptable to low and high temperatures, and they cause pollution after weathering. To address these issues, there is a need to design a snow-blocking facility that can adapt to complex terrain conditions, and because its lower part is suspended, snow accumulation is far from the snow barrier, providing long-term effective snow blocking, while using less concrete and having a lower cost. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a suspended snow barrier that is easy to construct, reduces costs, and can be used for a long time.

[0004] A suspended snow barrier includes a post with a suspended foundation at its base; a pit is excavated in the ground relative to the post and the suspended foundation; several ring hooks are provided on the post; a snow baffle is attached to each ring hook; and the snow baffle is connected to the post by an anti-detachment mechanism.

[0005] Furthermore, the suspended foundation includes a symmetrically arranged left base and a right base; both the left base and the right base are cast in place within the foundation pit.

[0006] Furthermore, the left base and the right base are respectively provided with through grooves; uprights are respectively provided on the left base and the right base; and screws are provided on the left and right sides of the uprights.

[0007] Furthermore, a clamp is slidably connected to the screw; a nut is also screwed onto the screw; the nut abuts against the clamp; and the clamp abuts against the column.

[0008] Furthermore, the portion of the foundation pit, excluding the columns and suspended foundations, is compacted to the original ground level.

[0009] Furthermore, the annular hooks are evenly distributed along the height direction of the column; the annular hooks are arranged around the outside of the column; the annular hooks on two adjacent columns correspond one-to-one.

[0010] Furthermore, the annular hook has openings on both the front and rear sides; the snow shield has snap-fit ​​protrusions at both ends; the snap-fit ​​protrusions are inserted into the openings.

[0011] Furthermore, the anti-detachment mechanism includes a first through hole and a second through hole in relative positions; the first through hole is formed on each snap-fit ​​protrusion and the annular hook; the second through hole is formed on the column; the first through hole and the second through hole correspond one-to-one.

[0012] Furthermore, the anti-detachment mechanism also includes a bendable anti-detachment pin; the bendable anti-detachment pin passes through the opposite first through hole and second through hole and is bent.

[0013] Furthermore, there is a gap between the bottommost snow shield and the ground.

[0014] This utility model has the following advantages: First, a cast-in-place suspended foundation is used in the foundation pit, and the support column is supported by a clamp; this eliminates the need for a complex pile foundation structure during the construction of the column, greatly reducing the amount of concrete used, reducing costs and increasing efficiency, while making construction more convenient; at the same time, the snow shield is supported and fixed by a ring hook and an anti-detachment mechanism, making the installation process convenient and preventing the snow shield from falling off under the action of wind.

[0015] Finally, because there is a gap between the bottom snow barrier and the ground, wind and snow can pass through, and snow will not accumulate in this area. Therefore, no large force will be generated in this area, ensuring that the snow barrier can be used for a long time. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] See Figures 1-5 This application discloses a suspended snow barrier, including a post 1, with a suspended foundation 2 at the bottom of the post 1; a pit is excavated in the ground relative to the post 1 and the suspended foundation 1; a plurality of ring hooks 3 are provided on the post 1; a snow baffle 4 is attached to each ring hook 3; and the snow baffle 4 is connected to the post 1 by an anti-detachment mechanism.

[0024] Furthermore, the suspended foundation 2 includes a symmetrically arranged left base 2-1 and a right base 2-2; both the left base 2-1 and the right base 2-2 are cast in place within the foundation pit.

[0025] Furthermore, the left base 2-1 and the right base 2-2 are respectively provided with through grooves; uprights 5 are respectively provided on the left base 2-1 and the right base 2-2; and screws 6 are provided on the left and right sides of the uprights 5.

[0026] Furthermore, a clamp 7 is slidably connected to the screw 6; a nut 8 is also screwed onto the screw 6; the nut 8 abuts against the clamp 7; and the clamp 7 abuts against the column 1.

[0027] Furthermore, the portion of the foundation pit, excluding the column 1 and the suspended foundation 2, is compacted to the original ground level.

[0028] Specifically, the left base 2-1 and right base 2-2 of the suspended foundation 2 are suspended within the foundation pit by cast-in-place concrete, and the column 1 also penetrates through the interior of the suspended foundation 2. By rotating the nut 8, the clamps 7 are displaced, and the two clamps 7 abut against the surface of the column from both sides to ensure the stability of the column 1. Finally, the foundation pit is compacted. This method eliminates the need for concrete pouring throughout the entire foundation pit, greatly reducing concrete usage and lowering costs.

[0029] Furthermore, the annular hooks 3 are evenly distributed along the height direction of the column 1; the annular hooks 3 are arranged around the outside of the column 1; the annular hooks 3 on two adjacent columns 1 correspond one-to-one.

[0030] Furthermore, the annular hook 3 has openings 3-1 on both the front and rear sides; the snow shield 4 has snap-fit ​​protrusions 4-1 at both ends; the snap-fit ​​protrusions 4-1 are inserted into the openings 3-1.

[0031] Furthermore, the anti-detachment mechanism includes a first through hole 9 and a second through hole 10 in relative positions; the first through hole 9 is opened on each snap-fit ​​protrusion 4-1 and the annular hook 3; the second through hole is opened on the column 1; the first through hole and the second through hole correspond one-to-one.

[0032] Furthermore, the anti-detachment mechanism also includes a bendable anti-detachment pin 11; the bendable anti-detachment pin 11 passes through the opposite first through hole and second through hole and is bent.

[0033] Furthermore, there is a gap between the bottommost snow shield and the ground.

[0034] Specifically, the snap-fit ​​protrusions 4-1 at both ends of the snow shield 4 can be easily inserted into the opening of the ring hook 3. Moreover, since the ring hook 3, the snap-fit ​​protrusions 4-1, and the post have a first through hole and a second through hole, after inserting the pin into the first through hole and the second through hole and bending it, the snow shield 4 can be fixed in the ring hook 3 to prevent it from falling off.
