Description

Technical Field

[0001] This utility model relates to the field of windbreak technology, and in particular to a windbreak barrier for beach backshore sandy land vegetation that is adaptive to wind pressure. Background Technology

[0002] Backshore sand dunes refer to depositional landform units primarily composed of sandy sediments that form inland from the mean high tide line. Backshore sand dune vegetation is mainly composed of wind-resistant, saline-tolerant, salt-spray-tolerant, drought-tolerant, and infertile-soil-tolerant woody or herbaceous plants, typically serving functions such as sand fixation and beach protection, increasing vegetation cover, enhancing the ecological function of the beach system, and also contributing to the beach landscape. Due to human activities and natural disasters damaging the beach ecosystem, backshore sand dune vegetation has degraded or even disappeared. In the process of restoring damaged backshore sand dune vegetation, it is necessary to preserve as much of the original sand dune vegetation as possible, fully utilize the soil seed bank and the natural succession process of plant communities, supplemented by necessary artificial planting, to restore the sand dune vegetation.

[0003] Setting up a windbreak along the outermost edge of the backshore sandy land vegetation on the same straight line perpendicular to the main wind direction plays a positive role in promoting natural vegetation recovery, protecting the vegetation restoration effect, ensuring the survival rate of vegetation, and enhancing the biodiversity of the backshore area.

[0004] Current technologies employ windbreaks with fixed heights, which cannot adapt to the protection needs of plants at different wind speeds and heights. Furthermore, current technologies do not consider the windbreaks' own ability to adapt to wind pressure, making them susceptible to structural damage during strong winds at the coast. Utility Model Content

[0005] The purpose of this invention is to provide a windbreak barrier for beach backshore sandy land vegetation that is adaptive to wind pressure, so as to alleviate the problem that the existing windbreak barrier itself has poor adaptability to wind pressure and is prone to structural damage in strong winds at the seaside.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0007] An adaptive wind pressure backshore vegetation windbreak for beach sandy areas, applied to beach sandy areas, includes: a fixing component, a barrier component, and a buffer component. The bottom of the fixing component is buried in the sand. The barrier component is disposed on the fixing component. One end of the buffer component is connected to the fixing component, and the other end is fixed to the sand.

[0008] The fixing component includes multiple spaced-apart first fixing piles, and the buffer component includes an elastic element. The top of the elastic element is connected to the first fixing piles, and the bottom of the elastic element is fixed to the sand through a fixing structure.

[0009] Furthermore, the buffer assembly also includes wire guy lines, with one wire guy line connected to each side of the first fixing post. The wire guy lines are threaded through the elastic element, and the bottom of the wire guy lines is connected to the fixing structure.

[0010] Furthermore, the fixing structure includes a connector and a second fixing pile, the wire guy wire is connected to the second fixing pile through the connector, and the bottom of the second fixing pile is fixed to the sand.

[0011] Furthermore, the fixing component also includes a bracing pile, the top of which is connected to the first fixing pile, and the first fixing pile connected to the bracing pile and the first fixing pile connected to the wire guy line are staggered, with the bottom of the bracing pile fixed to the sand.

[0012] Furthermore, the inclined bracing pile is fixed at the middle height of the ground portion of the first fixed pile, and the angle between the inclined bracing pile and the first fixed pile is 45°.

[0013] Furthermore, the bottoms of the first fixed pile, the second fixed pile, and the inclined brace pile are all wrapped with a fiber mesh structure.

[0014] Furthermore, the fiber web structure includes a biodegradable coconut shell fiber web.

[0015] Furthermore, the barrier assembly includes a windproof barrier, which is secured to the first fixed stake by a fixing rope.

[0016] Furthermore, the barrier assembly also includes a movable barrier and a movable stake, the movable barrier being secured to the movable stake by a fixing rope, and the movable stake being connected to the top of the first fixed stake by a height adjustment structure.

[0017] Furthermore, the height adjustment structure includes a plug at the bottom of the movable pile and a slot at the top of the first fixed pile. The plug and the slot are inserted into each other and fixed by a pin.

[0018] This utility model brings at least the following beneficial effects:

[0019] This utility model provides an adaptive wind pressure backshore sandy vegetation windbreak barrier for use on sandy beaches. It includes a fixing component, a barrier component, and a buffer component. The bottom of the fixing component is buried in the sand. The barrier component is disposed on the fixing component. One end of the buffer component is connected to the fixing component, and the other end is fixed to the sand. The fixing component includes multiple spaced-apart first fixing piles. The buffer component includes an elastic element. The top of the elastic element is connected to the first fixing piles, and the bottom of the elastic element is fixed to the sand through a fixing structure.

[0020] One end of the elastic element is connected to the first fixed pile, while the other end is fixed in the sand. When coastal winds are strong, the elastic element acts as a buffer, allowing the first fixed pile to tilt backward within a certain range to disperse wind pressure. After the wind weakens, the elastic element causes the first fixed pile to automatically return to its original position, improving its adaptability to wind pressure and reducing the risk of structural damage. The barrier components installed on the first fixed pile cause sand particles to deposit before and after the barrier, forming artificial sand dunes and protecting the root system of the backshore vegetation. The wind-pressure-adaptive beach backshore vegetation windbreak can be installed before the typhoon season and dismantled during the peak tourist season, thus balancing the needs of ecological protection and beach utilization. The materials of the wind-pressure-adaptive beach backshore vegetation windbreak are recyclable, and the vegetation system can self-sustain after removal, making it an effective tool for achieving sustainable coastal zone management.

[0034] Example 1

[0035] A windbreak barrier should be erected along the outermost edge of the coastal sandy vegetation on the same straight line perpendicular to the direction of the prevailing wind. Current technology uses windbreak barriers of fixed height, which cannot adapt to the protection needs of different wind forces and vegetation heights. Furthermore, current technology does not consider the windbreak barrier's own adaptability to wind pressure, making it susceptible to structural damage during strong coastal winds.

[0036] In view of this, the present invention provides an adaptive wind pressure backshore sandy vegetation windbreak barrier for use on sandy beaches, comprising: a fixing component, a barrier component, and a buffer component 200. The bottom of the fixing component is buried in the sand, the barrier component is disposed on the fixing component, one end of the buffer component 200 is connected to the fixing component, and the other end is fixed to the sand. The fixing component includes multiple spaced first fixing piles 100, and the buffer component 200 includes an elastic element 210. The top of the elastic element 210 is connected to the first fixing piles 100, and the bottom of the elastic element 210 is fixed to the sand through a fixing structure.

[0037] One end of the elastic element 210 is connected to the first fixed pile 100, and the other end is fixed in the sand. When the coastal wind is strong, the elastic element 210 can act as a buffer, allowing the first fixed pile 100 to tilt backward within a certain range to disperse wind pressure. After the wind weakens, the elastic element 210 causes the first fixed pile 100 to automatically return to its upright position, improving its adaptability to wind pressure and reducing the risk of structural damage. The barrier components installed on the first fixed pile 100 allow sand particles to be deposited before and after the barrier, forming artificial sand dunes and protecting the root system of the backshore vegetation. The wind-resistant backshore sandy vegetation windbreak can be installed before the typhoon season and dismantled during the peak tourist season, thus balancing the needs of ecological protection and beach utilization. The material of the wind-resistant backshore sandy vegetation windbreak is recyclable, and the vegetation system can self-sustain after removal, making it an effective tool for achieving sustainable management of the coastal zone.

[0038] In this embodiment, the first fixed stake 100 can be a cedar stake; the elastic element 210 can be a spring buffer, or other components that can provide elastic force.

[0039] In an optional embodiment, the buffer assembly 200 further includes a wire tie rod 220. A wire tie rod 220 is connected to each side of the first fixing post 100. The wire tie rod 220 passes through the elastic member 210, and a fixing structure is connected to the bottom of the wire tie rod 220.

[0040] Please see Figure 2 A wire guide 220 is connected to each side of the first fixed pile 100 to ensure that the first fixed pile 100 is subjected to uniform force. An elastic element 210 is wound around the wire guide 220. The top of the wire guide 220 is fixed to the top of the first fixed pile 100, and the bottom of the wire guide 220 is fixed to the sand through a fixing structure.

[0041] Furthermore, the fixing structure includes a connector 310 and a second fixing pile 320. The wire guy line 220 is connected to the second fixing pile 320 through the connector 310, and the bottom of the second fixing pile 320 is fixed to the sand.

[0042] Please see Figure 3 In this embodiment, the connector 310 can be a screw, and the bottom of the wire tie rod 220 is fastened to the screw and nailed into the top of the second fixing stake 320 to achieve tension. The second fixing stake 320 can be a wooden fixing stake, which is hammered and driven into the sand to fix it.

[0043] In an optional embodiment, the fixing component further includes a bracing pile 400, the top of which is connected to the first fixing pile 100, and the first fixing pile 100 connected to the bracing pile 400 and the first fixing pile 100 connected to the wire tie rod 220 are alternately arranged, and the bottom of the bracing pile 400 is fixed to the sand.

[0044] Please see Figure 2 and Figure 3 Both sides of the first fixed pile 100 connected to the inclined bracing pile 400 are connected to the buffer assembly 200, that is, the inclined bracing pile 400 and the buffer assembly 200 are arranged at intervals. The inclined bracing pile 400 is located on the leeward side of the first fixed pile 100, and can provide support for the first fixed pile 100 that is not connected to the buffer assembly 200.

[0045] Furthermore, the inclined bracing pile 400 is fixed at the middle height of the above-ground portion of the first fixed pile 100, with the angle between the inclined bracing pile 400 and the first fixed pile 100 being 45°. This arrangement makes the support effect of the inclined bracing pile 400 on the first fixed pile 100 better.

[0046] In an optional embodiment, the bottom of the first fixed pile 100, the second fixed pile 320, and the inclined bracing pile 400 are all wrapped with a fiber mesh structure 500.

[0047] Specifically, the fiber web structure 500 includes a biodegradable coconut shell fiber web.

[0048] Existing vegetation windbreaks are mostly used in inland areas, while coastal winds are stronger than inland winds. Furthermore, the application scenario in this embodiment is a sandy beach with smooth, loose sand grains, making it difficult to maintain stability using existing windbreaks. This embodiment wraps all the buried ends of the wooden stakes with biodegradable coconut fiber mesh, which increases the frictional resistance between the stakes and the sand grains, improving the stability of the adaptive windbreak for beach backshore sandy areas.

[0049] In an optional embodiment, the barrier assembly includes a windproof barrier 610, which is secured to the first fixed stake 100 by a fixing rope.

[0050] Please see Figure 1 The windbreak barrier 610 can be made of nylon netting, which is secured to each of the first fixed stakes 100 with nylon ropes. The nylon netting allows sand to be deposited in front of and behind it, thus forming artificial sand dunes and protecting the root system of the back shore vegetation.

[0051] In an optional embodiment, the barrier assembly further includes a movable barrier 620 and a movable stake 630. The movable barrier 620 is secured to the movable stake 630 by a fixing rope, and the movable stake 630 is connected to the top of the first fixed stake 100 by a height adjustment structure.

[0052] Please see Figure 1The movable barrier 620 can use the same nylon netting as the windbreak barrier 610 and be secured to each movable stake 630 with nylon ropes. The movable stakes 630 are connected to the first fixed stake 100 through a height adjustment structure, which allows for adjustment of the overall height of the barrier. This adapts to different sea wind intensities and the height requirements of different protected plants, effectively reducing physical damage to vegetation from wind and sand and improving plant survival rates.

[0053] As an alternative, the height adjustment structure includes a plug 710 located at the bottom of the movable post 630 and a slot 720 located at the top of the first fixed post 100. The plug 710 and the slot 720 are plugged into each other and are fixedly connected by a pin.

[0054] Please see Figure 1 The insert 710 can be inserted vertically into different depths within the slot 720. After insertion, the movable stake 630 is connected and fixed to the first fixed stake 100 via a pin. Alternatively, the height adjustment structure can also employ other structures such as a slider-slide connection, as long as it can adjust the height of the movable stake 630 extending beyond the first fixed stake 100.

[0055] The following describes the installation steps for windbreaks with adaptive wind pressure on beach backshore sandy areas:

[0056] S1: Bury a 2m high fir tree stump at a 1.5m interval, and wrap the buried end with biodegradable coconut fiber netting, with a burial depth of 70cm;

[0057] S2: At every interval of a cedar tree stump, a 3m long iron wire diagonal line 220 is stretched on each side of it. The iron wire diagonal line 220 is threaded through a spring buffer of the same length. The iron wire diagonal line 220 is bolted to a screw and nailed into a wooden fixing stake. The wooden fixing stake is 0.5m long. The buried end is wrapped with biodegradable coconut fiber mesh and then hammered and inserted into the sand to fix it.

[0058] S3: For the fir tree stump adjacent to the fir tree stump connected with the iron wire diagonal line 220, a fir tree stump is diagonally supported on its leeward side at an angle of 45°. One end is fixed with a steel nail at about half the height of the fir tree stump above ground, and the other end is wrapped with biodegradable coconut fiber mesh and then inserted into the sand.

[0059] S4: Secure the double-layer 100-mesh nylon netting to each cedar stump with nylon rope to form a windbreak barrier 610;

[0060] S5: When the sea breeze is strong or the protected sandy vegetation behind is tall, a movable stake 630 can be added to the top of the cedar stake in the above steps. A nylon net is tied to the movable stake 630 with nylon rope to form a movable barrier 620, and the height can be adjusted by the height adjustment structure.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
