Description

Technical Field

[0001] The invention relates to the technical field of snow and sand prevention, in particular to a herringbone snow and sand prevention wall structure. Background Art

[0002] In high-altitude and cold regions or areas with frequent sandstorms, infrastructure is often attacked by natural disasters such as snowstorms and sandstorms. These natural disasters not only cause serious obstacles and economic losses to transportation facilities such as roads and railways, but may also have an adverse impact on the operation of energy pipelines, communication lines and other key facilities. Snowstorms and sandstorms not only erode infrastructure, but also hinder its normal functions and even cause 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 wind, snow, and dust to a certain extent, but due to the limitations of their own design and material selection, there are still some significant problems. Their common characteristics are heavy structures, large material consumption, and complex construction processes, resulting in high overall costs. At the same time, such structures usually require regular maintenance, but maintenance is difficult and may have a negative impact on the surrounding environment during long-term use.

[0004] In addition, traditional structures are also insufficient in terms of wind, snow and sand prevention effects, and fail to fully utilize the kinetic energy of wind, snow and sand. These snow and sand prevention structures usually take the approach of completely blocking wind, snow, sand and dust, causing a large airflow pressure difference before and after the structure. This pressure difference not only easily causes wind, snow and sand to overflow above the structure, but also has a large impact and destructive force on the structure. Over time, this design defect may cause damage or even failure of the structure, further increasing maintenance costs and safety hazards.

[0005] In response to the above problems, a more efficient, economical and environmentally friendly design scheme for snow- and sand-proof structures is urgently needed; the ideal structure should achieve significant improvements in stability, construction convenience and snow- and sand-proof effects, while also having strong adaptability and being able to cope with a variety of terrains and complex climatic conditions. Summary of the invention

[0006] The present invention provides a herringbone snow and sand retaining wall structure to overcome the problems of insufficient wind and snow resistance of traditional snow and sand retaining wall structures.

[0007] To achieve the above purpose, the technical solution proposed by the present invention is:

[0008] A herringbone snow and sand barrier wall structure, characterized in that it comprises a windward plate, a leeward plate and a top connecting member, wherein the windward plate and the leeward plate are connected via the top connecting member, and a plurality of windward plates and leeward plates are sequentially arranged in a staggered manner, and the windward plate and the leeward plate form an angle structure with the upper ends close together and the lower ends separated;

[0009] The windward plate comprises a corrugated steel plate, the wave direction of which is a transverse wave arrangement, and the windward plate is close to the side of the wind direction;

[0010] The leeward plate comprises a corrugated steel plate, and the wave direction of the corrugated steel plate is a vertical wave arrangement.

[0011] Furthermore, the top connecting member is a hinged connecting member, which includes a hinged seat arranged on the upper ends of the windward plate and the leeward plate and a connecting shaft passing through the hinged seat.

[0012] Furthermore, the top connecting member is a fixed connecting member, and the fixed connecting member includes a connecting plate arranged at the upper ends of the windward plate and the leeward plate, and the connecting plates at the upper ends of the windward plate and the leeward plate are fixedly connected.

[0013] Furthermore, a movable support rod is provided between the windward plate and the leeward plate, one end of the movable support rod is connected to the windward plate or the leeward plate through a rotating shaft, and the other end is fixed to the windward plate or the leeward plate through a clamping structure.

[0014] Furthermore, a fixed support rod is provided between the windward plate and the leeward plate, and two ends of the fixed support rod are fixed to the windward plate and the leeward plate.

[0015] Furthermore, the lower ends of the windward plate and the leeward plate are connected to the underground foundation structure through bottom fixing components.

[0016] Furthermore, the underground foundation structure is a steel pipe pile, and the bottom fixing member includes a base plate, which is welded to the steel pipe pile.

[0017] Furthermore, the underground foundation structure is a concrete foundation, and the bottom fixing member includes a base plate, and the base plate is fixed to the concrete foundation by embedding anchor bolts.

[0018] Furthermore, reinforcing side plates are welded around the corrugated steel plate.

[0019] Furthermore, the waveform of the corrugated steel plate is a sinusoidal wave form, a triangular wave form, a trapezoidal wave form or a right-angle wave form.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The herringbone snow and sand retaining wall structure of the present invention adopts a herringbone (triangle) layout design, which makes the overall structure more stable and can achieve a higher retaining wall layout height; the waveform direction of the windward plate of the present invention is a transverse wave layout, which increases the resistance of the airflow when it directly goes over the plate body, and effectively reduces the impact of the wind on the top of the retaining wall; the waveform direction of the leeward plate is a vertical wave layout, which enhances the vertical stability and improves the structural strength of the leeward plate when it is mainly subjected to wind pressure; the staggered arrangement of transverse waves and longitudinal waves is combined with the herringbone overall structure to form a wind-guiding effect, and generate vortex counter-attack on the back of the windward plate, which not only effectively reduces the wind speed, but also generates reverse wind 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 accumulates behind the windward board and in front of the leeward board, it will destroy the vortex counteraction effect and cause the wind speed to increase; this increase in wind speed will have a displacement effect on the accumulated snow / sand, causing the accumulated snow / sand to form a stable wind resistance and support force after reaching the equilibrium point, further ensuring the continued stability of the structure.

[0023] Of course, the implementation of the various technical solutions of the present invention does not necessarily require achieving all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Embodiment 1:

[0034] See also Figure 1-Figure 3 The present embodiment provides a herringbone snow and sand blocking wall structure, comprising a windward plate 1, a leeward plate 2 and a top combining member 3, wherein the top combining member 3 is a hinged connector; the windward plate 1 and the leeward plate 2 are connected by a hinged connector 3, and the hinged connector 3 comprises a hinged seat and a connecting shaft; the hinged seat is a metal part with an inverted "U"-shaped cross-section, and the hinged seat is fixedly mounted on the upper end edges of the windward plate 1 and the leeward plate 2 respectively; the connecting shaft is made of high-strength alloy steel, and the connecting shaft passes through the hinged seat to connect the windward plate 1 and the leeward plate 2 together, thereby realizing flexible hinge connection of the top of the snow and sand blocking wall, and allowing adjustment of the angle between the windward plate 1 and the leeward plate 2 to adapt to different wind, snow and dust conditions; a ventilation gap is formed between the windward plate 1 and the leeward plate 2 by staggered arrangement. This design effectively avoids the accumulation of dust and snow while weakening wind load.

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

[0036] In this embodiment, the windward plate 1 is a corrugated steel plate with a transverse wave arrangement, and its waveform is designed to be a sine wave, and the direction of the corrugation is parallel to the ground; this waveform can effectively guide the airflow and increase the resistance of the airflow when it directly passes over the board body, thereby reducing the wind pressure on the top of the snow guard; the leeward plate 2 is a corrugated steel plate with a vertical wave arrangement, and the waveform is also a sine wave, and the direction is perpendicular to the ground. By enhancing the vertical stability, the structural strength of the leeward plate under the main wind pressure state is improved, and the amount of steel used is reduced. The corrugated steel plates of the windward plate 1 and the leeward plate 2 are welded with reinforcing side plates 5 around them, and the reinforcing side plates 5 further enhance the rigidity and deformation resistance of the board body.

[0037] A bottom fixing member is connected to the bottom of the windward plate 1 and the leeward plate 2, and the bottom fixing member is a base plate. The base plate is used to connect the lower ends 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 steel pipe piles 6, and the top of the steel pipe piles 6 is welded to the base plate, which ensures the stability and wind resistance of the overall structure.

[0038] The outer surfaces of the windward plate 1 and the leeward plate 2 are coated with anti-corrosion paint, thereby extending the service life of the retaining wall.

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

[0040] This embodiment achieves the adjustability of the angle between the windward plate and the leeward plate through an articulated connection, so that the snow and sand barrier wall structure can be flexibly adjusted according to different wind, snow and dust environmental conditions. For example, in areas with higher wind speeds, increasing the angle can enhance the wind blocking ability and improve the wind resistance of the structure; while in areas with lower wind speeds, reducing the angle can optimize the efficiency of material use.

[0041] The staggered arrangement of the windward and leeward boards makes full use of the ventilation characteristics of low-speed airflow, allowing part of the airflow to pass through the ventilation gaps instead of directly acting on the surface of the retaining wall, thereby effectively reducing the wind load on the structure; this design also optimizes the airflow distribution, allowing the snow guard to perform more efficiently when resisting strong winds.

[0042] The corrugated steel plates of the windward and leeward plates are arranged in transverse and vertical waves respectively, which further enhances the wind-guiding performance: the transverse wave arrangement of the windward plate increases the resistance of the airflow when it passes over the plate, effectively weakening the direct impact of the airflow; the vertical wave arrangement of the leeward plate enhances the vertical stability of the plate and increases the damping effect of the airflow passing through the gap. This coordinated design of the corrugation direction not only improves the overall wind resistance of the structure, but also further reduces the cost by reducing wind pressure and material usage.

[0043] See also Figure 4When the airflow acts on the herringbone snow and sand retaining wall structure, due to the geometric arrangement of the windward plate and the leeward plate and the synergistic effect of the corrugation direction, a vortex counter-attack area will be formed on the back of the windward plate and in front of the leeward plate; this vortex counter-attack 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 reverse wind pressure on the back of the windward plate; the reverse wind pressure provides additional support for the windward plate, thereby reducing the structural strength required for the windward plate, further optimizing the amount of steel used and reducing costs.

[0044] At the same time, the eddy counteraction effect also significantly affects the accumulation behavior of snow and dust around the snow shield; when snowflakes or dust contact the windward plate with the airflow, most of the particles will be guided to slide downward due to the airflow disturbance, while the particles passing through the ventilation gap will be further dispersed on the front side of the leeward plate; as the wind speed decreases, the snow and dust gradually accumulate to the bottom of the windward and leeward plates, but this accumulation will destroy the balance of eddy counteraction, thereby causing a local rebound in wind speed; this rebound in wind speed has a displacement effect on the accumulated snow and dust, prompting them to redistribute, and finally reach a dynamic balance, forming a stable wind resistance and support force.

[0045] The herringbone structure design 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, the accumulated snow can slide down to the back of the leeward plate, thereby avoiding the snow pressure on the snow guard caused by the long-term stay of the snow. This design effectively reduces the accumulation of snow and dust, reduces maintenance costs, and significantly extends the service life of the snow guard.

[0046] The optimized design based on fluid mechanics in this embodiment makes the herringbone snow guard more efficient and reliable in protecting against wind, snow and dust; the combination of vortex guidance, dynamic balance and natural snow removal functions enables it to exhibit excellent performance under complex and changeable natural environmental conditions.

[0047] The snow and sand retaining wall structures of this embodiment can be continuously arranged in pairs on both sides of the roadbed to form a snow and sand barrier, which can effectively prevent wind, snow and sand from burying the road and ensure the smooth and safe road. In addition, due to its high stability and flexibility in structural design, the structure is not only suitable for roads and railways, but can also be widely used in scenes such as the vicinity of airport runways, wind and sand control areas of open-pit mines, farmland shelterbelt areas, and mountain slopes with frequent wind and snow.

[0048] Embodiment 2:

[0049] The present embodiment provides a herringbone snow and sand barrier wall structure, comprising a windward plate, a leeward plate and a top combining component, wherein the top combining component is a fixed connecting component; the windward plate and the leeward plate are connected via a top combining component, and the top combining component comprises a connecting plate, wherein the connecting plate is an L-shaped steel or a flat steel structure, wherein one end of the connecting plate is fixed to the upper end of the windward plate by welding or bolts, and the other end is connected to the upper end of the leeward plate by welding or bolts to form a fixedly combined structure; in the present embodiment, the angle between the windward plate and the leeward plate connected by the fixed connecting component is 30 degrees, and the structure is stable and easy to install.

[0050] In this embodiment, the specific dimensions 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, the corrugated steel plates of the windward plate and the leeward plate are welded with reinforcing side plates around them. The size of the reinforcing side plates is 50 mm wide and 5 mm thick, which effectively improves the bending strength and deformation resistance of the plate body. The outer surface of the windward plate and the leeward plate is coated with an anti-corrosion coating with a thickness of 0.3 mm, which further extends the service life of the retaining wall.

[0051] The windward plate is made of corrugated steel plate with transverse wave arrangement, and its wave shape is designed as a sine wave, and the wave direction is parallel to the ground; the leeward plate is made of corrugated steel plate with vertical wave arrangement, and the wave shape is also a sine wave, and the direction is perpendicular to the ground. This coordinated design of the wave direction enhances the wind-guiding performance: the transverse wave arrangement of the windward plate increases the resistance of the airflow when it passes over the plate body, effectively weakening the direct impact of the airflow; the vertical wave arrangement of the leeward plate further improves the wind resistance of the structure by enhancing the vertical stability of the plate body and increasing the damping effect when the airflow passes through the gap.

[0052] A plurality of fixed support rods are arranged between the windward plate and the leeward plate to enhance the stability of the structure. The two ends of the fixed support rods are respectively connected to the windward plate and the leeward plate by welding or bolts to ensure that the angle between the windward plate and the leeward plate remains unchanged and to improve the overall wind load resistance of the structure.

[0053] Bottom fixing members are provided at the bottom of the windward plate and the leeward plate. In the present embodiment, the bottom fixing member is a base plate having dimensions of 400 mm × 300 mm × 20 mm (length × width × thickness). The base plate is fixed to the concrete foundation by anchor bolts.

[0054] The geometric arrangement of the windward and leeward boards and the synergistic effect of the corrugation direction form an eddy current counteraction effect on the back of the windward board, significantly reducing the wind speed in the local area on the back of the windward board and generating reverse wind pressure on the back of the windward board, providing additional support for the windward board, thereby reducing the structural strength required for the windward board. This optimized design enables the snow and sand retaining walls to demonstrate excellent performance in wind, snow and dust protection, while facilitating large-scale promotion and application.

[0055] See also Figure 5 In other embodiments, the waveform of the corrugated steel plate may be in a triangular wave form, a trapezoidal wave form, a right-angle wave form or other forms.

[0056] For those skilled in the art, several improvements and modifications may be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as within the scope of protection of the present invention.
