Description

Technical Field

[0001] The invention relates to the technical field of engineering sand prevention, in particular to a multifunctional segmented combined sand retaining wall system. Background Art

[0002] Sand retaining wall is an important engineering facility for wind prevention and sand fixation. Its main function is to block wind and sand, reduce the erosion and damage of wind and sand to specific areas such as railways, roads, farmlands, residential areas, etc., reduce wind speed so that wind and sand are deposited nearby. At the same time, it can also protect the ecological environment, maintain the stability of the surrounding ecosystem, and create a suitable environment for vegetation growth. It is widely used in the fields of transportation, agriculture and ecological restoration projects.

[0003] If the height of the protective net is too low, it may not play a good role in preventing wind and sand. If the height is too high, the stability of the protective net itself will be affected under severe weather conditions such as strong winds, and it will be easily blown down or damaged by the wind. Therefore, the height of the protective net is generally between 1-3 meters. However, wind and sand are easy to accumulate in front of the protective net, causing a certain load on the sand retaining net. In areas where sand prevention is required, the land is generally relatively loose, so the sand retaining net is easily collapsed under the pressure of accumulated sand. In response to this situation, the present invention proposes a new solution. Summary of the invention

The lower sand retaining structure, the middle sand retaining structure and the upper sand retaining structure form a three-stage sand prevention structure.

[0006] Further regarding this solution, the upper sand retaining structure includes a plate frame, side plates are fixed at both ends of the top of the plate frame, a rotating rod is rotatably installed between the side plates, a sand retaining net is fixedly wrapped around the surface of the rotating rod, a rotating shaft rod is rotatably installed between the two side plates close to the plate frame, a quicksand plate is fixed on the surface of the rotating shaft rod, and the edge of the sand retaining net is connected to the edge of the quicksand plate on one side away from the rotating shaft rod.

[0007] Further to this solution, diaphragms are fixed to both ends of the rotating shaft rod, and the diaphragms are also connected to quicksand plates, which are plastic plates or acrylic plates to reduce friction of rolling sand particles.

[0008] Furthermore, regarding this solution, a cavity is provided on the top of the frame, and supporting tubes are fixed at both ends of the bottom of the frame. The ends of the supporting tubes are connected by a sand-burying tube, and the sand falling into the cavity enters the sand-burying tube through the supporting tube.

[0009] Further to this scheme, the support piles are arranged at an angle, and are inserted into the sand at an angle of 15-30 degrees. The side panels are fixed to the top of the frame in a vertical state, and the inner wall of the bottom of the cavity at the frame is also arranged at an angle, and a protrusion is also provided on the inner wall of the bottom of the cavity, which is inclined from the middle of the cavity to the two ends close to the side panels.

[0010] Further to this solution, a crank is rotatably mounted on the side plate, the crank is coaxially fixed with the rotating rod for realizing the reeling of the sand retaining net, and a fixing bolt is screwed on the crank for fixing the crank.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Normally, the speed of wind and sand at 1 meter is relatively low. This is because the area close to the ground is greatly affected by the friction of the ground. The wind will encounter more resistance when flowing close to the ground, thereby slowing down the speed of the wind and sand. The speed of wind and sand at 3 meters is often faster. With the increase of height, the influence of ground friction gradually weakens, and the resistance to wind flow decreases, allowing the wind and sand to move at a faster speed and carry more sand particles. The wind and sand at 2 meters are less affected by the friction of the ground and have a relatively fast speed, but compared with 3 meters, they are affected by a certain degree of ground interference and have a slightly slower speed. The speed of wind and sand at this height is more moderate. It has a certain kinetic energy, but is not as high and stable as at 3 meters.

[0021] like Figure 1 As shown, the present invention provides a technical solution: a multifunctional segmented combined sand retaining wall system, comprising two supporting piles 1, a lower sand retaining structure 2, a middle sand retaining structure 3 and an upper sand retaining structure 4, wherein the middle sand retaining structure 3 and the lower sand retaining structure 2 are both installed between the two sides of the two supporting piles 1, and the middle sand retaining structure 3 is installed above the lower sand retaining structure 2, and the upper sand retaining structure 4 is installed on the top of the supporting pile 1, and the lower sand retaining structure 2, the middle sand retaining structure 3 and the upper sand retaining structure 4 form a three-section sand-proof structure, and the bottom of the supporting pile 1 is a ground nail 7 for easy fixation. Generally speaking, at a height of 1-3 meters, more sand is carried at high altitude and the wind speed is faster, while less sand is carried at low altitude and the wind speed is slower. The three-section sand-proof structure is used to perform differentiated treatment on the wind and sand conditions at different heights in the same area to achieve a better sand-proofing effect.

[0022] like Figure 2 As shown, the upper sand retaining structure 4 includes a plate frame 401, side plates 404 are fixed at both ends of the top of the plate frame 401, a rotating rod is rotatably installed between the side plates 404, a sand retaining net 406 is fixedly wrapped around the surface of the rotating rod, a rotating shaft rod 408 is rotatably installed between the two side plates 404 close to the plate frame 401, a quicksand plate 411 is fixed on the surface of the rotating shaft rod 408, the edge of the sand retaining net 406 is connected to the edge of the quicksand plate 411 away from the rotating shaft rod 408, and diaphragm sheets 407 are also fixed at both ends of the rotating shaft rod 408, and the diaphragm sheets 407 are also connected to the quicksand plate 411. After the sand retaining net 406 is opened, the diaphragm sheets 407 at both ends can reduce the situation where wind and sand flow out of the cavity between the sand retaining net 406 and the supporting pile 1. Through the arrangement of the above structure, the sand blocking net 406 can be rolled up on the surface of the rotating rod and opened when in use. When blocking sand, the sand blocking net 406 is opened and connected to the quicksand plate 411. The quicksand plate 411 is a plastic plate or an acrylic plate to reduce friction. After the sand blocking net 406 completes the sand blocking action, the sand will flow down from the quicksand plate 411. A cavity 402 is provided on the top of the plate frame 401. The cavity 402 can hold sand. The sand flowing down from the quicksand plate 411 enters the cavity 402 under the action of gravity. Support pipes 5 are fixed at both ends of the bottom of the plate frame 401. The ends of the support pipes 5 are connected by a sand burying tube 6. The sand falling into the cavity 402 will enter the sand burying tube 6 through the support pipe 5.

[0023] like Figure 2 and Figure 3As shown, it should be known that when the sand retaining wall system is installed, the supporting pile 1 is tilted and inserted into the sand at an angle of 15°-30°, and the side plate 404 is fixed to the top of the plate frame 401 in a vertical state. The bottom inner wall of the cavity 402 at the plate frame 401 is also tilted, and a protrusion 403 is also provided on the bottom inner wall of the cavity 402. The protrusion 403 is tilted from the middle of the cavity 402 to the two ends close to the side plate 404. Therefore, in this case, when the sand flows into the cavity 402, it automatically flows to the two ends and enters the sand-burying tube 6 after passing through the supporting through pipe 5. During the implementation process, the sand-burying tube 6 will increase in weight due to the increase in sand, and because it is buried in the sand, the sand-burying tube 6 is fully in contact with the sand. After increasing its own weight, it provides sufficient stability for the supporting pile 1.

[0024] A crank 409 is rotatably mounted on one of the side panels 404. The crank 409 is coaxially fixed with the rotating rod for realizing the reeling of the sand retaining net 406. A fixing bolt 410 is screwed on the crank 409 for fixing the crank 409. Sockets 102 are provided on the tops of both sides of the supporting piles 1, and plug blocks 405 are fixed at both ends of the bottom of the plate frame 401. The installation of the upper sand retaining structure 4 is realized by inserting the plug blocks 405 into the slots 102.

[0025] like Figure 4 As shown, the middle sand retaining structure 3 includes an outer frame 301 and a plurality of spacing frames 302, each spacing frame 302 is in a flat "mouth" shape, the spacing between every two spacing frames 302 is 1cm-5cm, and each spacing frame 302 is slidably connected, and a limiting block 303 is fixed on the inner side of each spacing frame 302, and a notch is arranged on one side of the limiting block 303, and a convex block 305 is fixed at a corresponding position on the outer side of the adjacent spacing frame 302, and the convex block 305 slides in the notch, and a spring 304 is arranged between the convex block 305 and one end of the notch, and in the absence of external force, each spacing frame 302 can be translated under the push of the spring 304, and in the actual installation process, the spacing frame 302 is translated and pushed out under the action of the spring 304 to form a stepped mesh structure, and the stepped mesh structure faces the side where the wind blows.

[0026] This stepped mesh structure can weaken wind and sand to a certain extent. Since the stepped mesh structure is overall conical in shape, after the wind and sand hit the stepped mesh structure, they will disperse in all directions, weakening the impact effect of the wind and sand, so that the kinetic energy of the wind and sand is dispersed and consumed, thereby reducing the wind speed and weakening the sand carrying capacity of the wind and sand. At the same time, when the fan hits the stepped mesh structure, due to the connection effect of the spring 304, when the wind and sand hit the stepped mesh, the spacer frame 302 will repeatedly shake under the effect of the spring 304, further increasing the turbulence effect and reducing the possibility of sand particles getting stuck in the gap.

[0027] like Figure 4 As shown, the lower sand retaining structure 2 includes a sand-proof net 201, a top plate 204 is fixed on the top of the sand-proof net 201, and an outer frame 301 is fixedly installed on the top of the top plate 204. A rail groove 101 is provided on the side of the two supporting piles 1 facing the sand-proof net 201, and side plates 202 are provided at both ends of the sand-proof net 201 near the supporting piles 1. The side plates 202 are connected to the sand-proof net 201 by a connecting wire mesh 203, and the connecting wire mesh 203 is made of an elastic material such as iron or rubber, and the side plates 202 slide in the rail groove 101 at the supporting pile 1.

[0028] It should be noted that the length of the track groove 101 is at least twice the width of the two ends of the sand-proof net 201, the width of the upper half of the track groove 101 is adapted to the side plate 202, and the side plate 202 is inserted into the track groove 101 from the upper half of the track groove 101 and moved downward. Through the setting of this structure, it has a blocking effect on wind and sand, and the elastic connecting wire mesh 203 on both sides can make the sand-proof net 201 shake repeatedly, which also has a good disturbing effect, reduces the speed of wind and sand, and weakens the sand carrying effect of wind and sand.

[0029] In summary, the multifunctional segmented combined sand retaining wall system provided in this embodiment has a significant sand retaining effect. The system is composed of a three-stage sand retaining structure consisting of a supporting pile 1, a lower sand retaining structure 2, a middle sand retaining structure 3 and an upper sand retaining structure 4, which can perform differentiated treatments for wind and sand conditions at different heights in the same area. In the upper sand retaining structure 4, the sand retaining net 406 can be rolled up on the surface of the rotating rod, and when in use, it is opened and connected to the quicksand plate 411. After the sand retaining action is completed, the sand flows down from the quicksand plate 411, and enters the buried sand tube 6 through the cavity 402 and the supporting through pipe 5, and the increased weight provides stability for the supporting pile 1. The stepped mesh structure of the middle sand retaining structure 3 can be pushed out horizontally under the action of the spring 304, and is in a cone shape facing the wind direction, which can weaken the wind and sand, so that the wind and sand are dispersed in all directions after the impact, reducing the wind speed and weakening the sand carrying capacity. At the same time The partition frame 302 swings repeatedly under the action of the spring 304, which increases the disturbance effect and reduces the possibility of sand getting stuck in the gap. The sand-proof net 201 of the lower sand retaining structure 2 is slidably installed in the track groove 101 of the supporting pile 1 through the side plate 202. The elastic connecting wire mesh 203 on both sides makes the sand-proof net 201 swing repeatedly, which has a good disturbance effect, reduces the speed of wind and sand and weakens the effect of carrying sand. On the whole, the sand retaining wall system effectively blocks and weakens the wind and sand through the synergistic effect of the various structures.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is limited by the attached embodiments and their equivalents.
