Description

TECHNICAL FIELD

[0001] The utility model relates to snow and sand prevention technical field, specifically, a herringbone snow and sand prevention wall structure. BACKGROUND

[0002] In alpine regions or areas prone to sandstorms, infrastructure is often subjected to natural disasters such as snow, wind, and sand. These natural disasters not only cause serious obstacles and economic losses to transportation facilities such as highways and railways, but also may adversely affect the operation of energy pipelines, communication lines and other critical facilities. Snow and sand accumulation not only erodes infrastructure, but also hinders its normal function, and even causes safety accidents.

[0003] Existing snow and sand prevention structures mainly include concrete retaining walls, masonry retaining walls, wooden retaining walls, and grid retaining walls. These structures have the ability to resist snow and sand to some extent, but due to limitations in design and material selection, there are still some significant problems. Their common characteristics are heavy structure, large material consumption, complex construction process, resulting in high overall cost. At the same time, such structures usually need regular maintenance, but the maintenance is difficult, and may have negative effects on the surrounding environment in the long term.

[0004] In addition, traditional structures also have deficiencies in snow and sand prevention, and do not fully utilize the kinetic energy of snow and sand; these snow and sand prevention structures usually adopt the way of completely blocking snow and sand, which forms a large pressure difference in the airflow before and after the structure. This pressure difference not only easily causes snow and sand to overflow above the structure, but also generates a large impact force and destructive force on the structure. With the passage of time, this design defect may cause damage or even failure of the structure, further increasing maintenance costs and safety hazards.

[0005] In view of the above problems, there is an urgent need for a more efficient, more economical and environmentally friendly snow and sand prevention structure design; an ideal structure should achieve significant improvement in stability, construction convenience and snow and sand prevention effect, while having strong adaptability to cope with various terrains and complex climate conditions. SUMMARY

[0006] The utility model provides a herringbone snow and sand prevention wall structure to overcome the problems of insufficient wind and snow resistance of traditional snow and sand prevention wall structures.

[0013] Further, a movable supporting rod is arranged between the windward board and the leeward board, one end of the movable supporting rod is connected with the windward board or the leeward board through a rotating shaft, and the other end of the movable supporting rod is fixed with the windward board or the leeward board through a clamping structure.

[0014] Further, a fixed supporting rod is arranged between the windward board and the leeward board, and two ends of the fixed supporting rod are fixed with the windward board and the leeward board.

[0015] Further, the lower end of the windward board and the leeward board is connected to an underground foundation structure through a bottom fixing component.

[0021] The herringbone-shaped snow and sand blocking wall structure of the utility model is designed in a herringbone shape (triangle), which makes the overall structure more stable and can achieve a higher blocking wall layout height; the wave direction of the windward plate is arranged in a transverse wave, which increases the resistance when the airflow directly jumps over the plate body, effectively reducing the impact of the wind on the top of the blocking wall; the wave direction of the leeward plate is arranged in a vertical wave, which enhances the vertical stability and improves the structural strength of the leeward plate under the condition of mainly wind pressure; the staggered arrangement of the transverse wave and the longitudinal wave is combined with the herringbone overall structure to form a wind guiding effect, which generates vortex collision on the back of the windward plate, effectively reduces the wind speed, and generates reverse air pressure, thereby enhancing the support stability of the back of the windward plate.

[0022] In addition, in the case of snow / sand deposition, when the accumulated snow / sand is accumulated behind the windward plate and in front of the leeward plate, the vortex collision effect will be destroyed and the wind speed will be increased; this increase in wind speed will cause the accumulated snow / sand to move, so that the accumulated snow / sand forms stable wind resistance and support force after reaching the balance point, further ensuring the continuous stability of the structure.

[0033] Embodiment 1:

[0034] Referring to Figures 1-3 , the present embodiment provides a herringbone snow and sand blocking wall structure, which comprises a windward plate 1, a leeward plate 2 and a top end connecting member 3, the top end connecting member 3 is a hinged connecting member; the windward plate 1 and the leeward plate 2 are connected through the hinged connecting member 3, the hinged connecting member 3 comprises a hinged seat and a connecting shaft; the hinged seat is a metal piece with a reversed "U" shaped cross section, the hinged seat is fixedly installed at the upper end edge of the windward plate 1 and the leeward plate 2 respectively; the connecting shaft is made of high-strength alloy steel, the connecting shaft penetrates through the hinged seat to connect the windward plate 1 and the leeward plate 2 together, so as to realize flexible hinging of the top end of the snow and sand blocking wall, and allow adjustment of the included angle between the windward plate 1 and the leeward plate 2 to adapt to different wind, snow and sand conditions; the windward plate 1 and the leeward plate 2 are arranged in a staggered manner to form a wind gap, which design not only weakens the wind load, but also effectively avoids the accumulation of sand and snow.

[0035] In order to enhance the stability of the structure and lock the included angle between the windward plate 1 and the leeward plate 2, a plurality of movable supporting rods 4 are arranged between the windward plate 1 and the leeward plate 2; in the present embodiment, one end of the movable supporting rod 4 is fixedly connected with the windward plate 1 through a rotating shaft, and the other end is fixedly connected with the leeward plate 2 through a clamping structure, the clamping structure comprises a socket and a plug, the socket is welded on the surface of the leeward plate 2; the plug is arranged at the end of the movable supporting rod 4, the plug is partially inserted into the socket, and is fixedly connected through a locking pin; the movable supporting rod 4 can realize precise locking of the included angle through the cooperation of the rotating shaft and the clamping structure while providing supporting force, so as to ensure that the windward plate 1 and the leeward plate 2 can maintain the set state after the included angle is adjusted; the movable supporting rod also has the function of quick disassembly, which is convenient for construction, maintenance and transportation of the snow and sand blocking wall structure.

[0036] In this embodiment, the windward plate 1 adopts a transverse wave arrangement of corrugated steel plate, and the wave shape is designed as a sine wave shape, and the corrugated direction is parallel to the ground. This wave shape can effectively guide the airflow and increase the resistance when the airflow directly jumps over the plate body, thereby reducing the wind pressure on the top of the snow baffle. The leeward plate 2 adopts a vertical wave arrangement of corrugated steel plate, and the wave shape is also a sine wave shape, and the direction is perpendicular to the ground. By enhancing the vertical stability, the structural strength of the leeward plate under the condition of mainly wind pressure is improved, and the amount of steel material is reduced. The corrugated steel plate of the windward plate 1 and the leeward plate 2 is welded with a reinforcing edge plate 5 around, which further enhances the rigidity and anti-deformation ability of the plate body.

[0037] A bottom fixing member is connected to the bottom of the windward plate 1 and the leeward plate 2, which is a base plate used to connect the lower end of the windward plate 1 and the leeward plate 2 to the underground foundation structure. In this embodiment, the underground foundation structure is in the form of a steel pipe pile 6, and the top of the steel pipe pile 6 is welded with the base plate, which ensures the stability and wind resistance of the overall structure.

[0038] A corrosion-resistant coating is coated on the outer surface of the windward plate 1 and the leeward plate 2, which prolongs the service life of the retaining wall.

[0039] In high wind load or special environment, by opening a wind hole on the surface of the windward plate 1, the wind resistance can be further reduced, and the overall performance can be optimized.

[0040] In this embodiment, the adjustability of the included angle between the windward plate and the leeward plate is realized by the hinged connecting piece, so that the snow and sand retaining wall structure can be flexibly adjusted according to different wind, snow and sand environment conditions. For example, in the area with high wind speed, the increase of the included angle can enhance the wind resistance and improve the wind resistance performance of the structure; and in the area with low wind speed, the reduction of the included angle can optimize the material use efficiency.

[0041] The staggered arrangement of the windward plate and the leeward plate fully utilizes the air permeability characteristics of low-speed airflow, so that part of the airflow can pass through the air permeable gap instead of directly acting on the surface of the retaining wall, thereby effectively reducing the wind load of the structure. This design also optimizes the airflow distribution, so that the snow baffle shows more efficient performance when resisting strong wind.

[0042] The corrugated steel plates of the windward plate and the leeward plate are arranged in transverse wave and vertical wave respectively, which further enhances the wind guiding performance. The transverse wave arrangement of the windward plate increases the resistance of the airflow when jumping over the plate body, effectively weakening the direct impact force of the airflow. The vertical wave arrangement of the leeward plate enhances the vertical stability of the plate body, and at the same time increases the damping effect when the airflow passes through the gap. This matching design of the corrugated direction not only improves the overall wind resistance of the structure, but also further reduces the cost by reducing the wind pressure and the amount of material used.

[0043] Referring to Figure 4When the airflow acts on the herringbone snow and sand blocking wall structure, due to the geometric arrangement of the windward plate and the leeward plate and the synergy of the corrugation direction, a vortex counter-shock area will be formed on the back of the windward plate and the front of the leeward plate; this vortex counter-shock effect effectively changes the movement path of the airflow, significantly reduces the wind speed in the local area on the back of the windward plate, and generates a reverse wind pressure on the back of the windward plate; the reverse wind pressure provides additional support for the windward plate, thereby reducing the required structural strength of the windward plate, further optimizing the amount of steel used and reducing the cost.

[0044] At the same time, the vortex counter-shock effect also significantly affects the accumulation behavior of snow and sand around the snow blocking plate; when snowflakes or sand dust contact the windward plate with the airflow, most of the particles will be guided to slide downward due to airflow disturbance, and the particles passing through the air gap will be further dispersed on the front side of the leeward plate; as the wind speed decreases, snow and sand gradually accumulate to the bottom of the windward plate and the leeward plate, but this accumulation will disrupt the balance of the vortex counter-shock, causing a local rise in wind speed; this rising wind speed causes the accumulated snow and sand to move, prompting them to redistribute, and eventually reaching a dynamic balance, forming stable wind resistance and support.

[0045] The design of the herringbone structure in this embodiment also has a natural snow removal function: due to the inclined arrangement of the windward plate and the leeward plate and the guiding effect of the low wind speed area, snow can slide naturally to the back of the leeward plate, thereby avoiding the snow pressure generated by the long-term stay of snow on the snow blocking plate; this design effectively reduces the accumulation of snow and sand while reducing maintenance costs and significantly extending the service life of the snow blocking plate.

[0046] The optimized design based on fluid mechanics in this embodiment makes the herringbone snow blocking plate more efficient and reliable in snow and sand protection; the combination of vortex guidance, dynamic balance and natural snow removal function makes it perform excellently in complex and variable natural environmental conditions.

[0047] The snow and sand blocking wall structure of this embodiment can be arranged in pairs on both sides of the roadbed to form a barrier against snow and sand, which can effectively block the burial of snow and sand on the road and ensure the smoothness and safety of the road; in addition, due to its high stability and flexibility in design, this structure is not only suitable for roads and railways, but also can be widely used in airport runway periphery, wind and sand control area of open-pit mine, farmland protection forest zone and snow and wind prone mountain slope surface, etc.

[0048] Embodiment 2:

[0049] The embodiment provides a herringbone-shaped snow and sand blocking wall structure, which comprises a windward plate, a leeward plate and a top end combining component, the top end combining component is a fixed connecting piece; the windward plate and the leeward plate are connected through the top end combining component, and the top end combining component comprises a connecting plate, the connecting plate is an L-shaped steel or a flat steel structure, one end of the connecting plate is fixed with the upper end of the windward plate through welding or a bolt, and the other end is connected with the upper end of the leeward plate through welding or a bolt, so that a fixed combined structure is formed; in the embodiment, the included angle between the windward plate and the leeward plate connected by the fixed connecting piece is 30 degrees, the structure is stable and simple to install.

[0050] In the embodiment, the specific sizes of the windward plate and the leeward plate are as follows: the plumb height of the windward plate and the leeward plate is 500 mm, and the width of the windward plate and the leeward plate is 150 mm. In order to improve the structural strength and durability of the windward plate and the leeward plate, reinforcing edge plates are welded around the corrugated steel plates of the windward plate and the leeward plate, the reinforcing edge plates are 50 mm wide and 5 mm thick, and the bending strength and deformation resistance of the plate body are effectively improved. Anti-corrosion paint is coated on the outer surfaces of the windward plate and the leeward plate, and the thickness of the anti-corrosion paint is 0.3 mm, so that the service life of the blocking wall is further prolonged.

[0051] The windward plate adopts a horizontally arranged corrugated steel plate, the wave shape of which is a sine wave shape, and the corrugated direction is parallel to the ground; the leeward plate adopts a vertically arranged corrugated steel plate, the wave shape of which is also a sine wave shape, and the direction is perpendicular to the ground. The cooperative design of the corrugated directions enhances the wind guiding performance: the horizontally arranged corrugated steel plate of the windward plate increases the resistance of airflow when it surmounts the plate body, effectively weakening the direct impact force of the airflow; the vertically arranged corrugated steel plate of the leeward plate enhances the vertical stability of the plate body, and at the same time, increases the damping effect when the airflow passes through the gap, further improving the wind resistance of the structure.

[0052] A plurality of fixed support rods are arranged between the windward plate and the leeward plate, for enhancing the stability of the structure. The two ends of the fixed support rod are connected to the windward plate and the leeward plate through welding or a bolt, so that the included angle between the windward plate and the leeward plate is fixed and unchanged, and the wind load capacity of the whole structure is improved.

[0053] A bottom fixing component is arranged at the bottom of the windward plate and the leeward plate, and in the embodiment, the bottom fixing component is a base plate, the size of which is 400 mm*300 mm*20 mm (length*width*thickness), and the base plate is fixed with the concrete foundation through an anchor bolt.

[0054] The geometric arrangement of the windward plate and the leeward plate and the cooperative effect of the corrugated directions form a vortex counter-shock effect on the back surface of the windward plate, significantly reducing the wind speed of the local area on the back surface of the windward plate, and generating a reverse wind pressure on the back surface of the windward plate, thereby providing additional support force for the windward plate, so that the required structural strength of the windward plate is reduced. This optimized design enables the snow and sand blocking wall to exhibit excellent performance in wind and snow and sand protection, and is convenient for large-scale popularization and application.

[0055] Referring to Figure 5 In other embodiments, the corrugated steel plate can have a triangular corrugation, a trapezoidal corrugation, or a right-angled corrugation, or other forms.
