Abstract
Description
Technical Field
[0001] This application relates to the field of urban environmental governance technology, and in particular to an ecological restoration structure for urban wasteland. Background Technology
[0002] As urbanization accelerates, a large number of buildings are constructed, and a large amount of construction soil is transferred to designated locations for dumping. These dumped sites are abandoned because they will not be developed again in the short term, resulting in many abandoned lands.
[0003] These abandoned sites are usually composed mainly of deep underground soil excavated during the construction process. When exposed to the environment, this deep underground soil will not grow vegetation in the short term, making the abandoned sites appear rather abrupt in urban aerial photography and greatly affecting the city's aesthetics.
[0004] The usual solutions to this are to cover the abandoned land with green plastic netting or to plant greenery on the land.
[0005] While covering cities with green plastic netting may look more aesthetically pleasing in the short term from an aerial perspective, in the long run, the plastic netting is difficult to decompose and will cause plastic pollution to the soil in abandoned sites.
[0006] While planting greenery does not pollute the soil, the process involves a series of tedious operations such as digging holes, covering with soil, and watering, requiring a significant investment of manpower and resources, and thus has obvious shortcomings. Utility Model Content
[0007] In order to improve the problem of abandoned land affecting the aesthetics of cities, this application provides an ecological restoration structure for urban abandoned land.
[0008] The ecological restoration structure for urban wasteland provided in this application adopts the following technical solution:
[0009] An ecological restoration structure for urban wasteland includes a laying box with a hinged lid. A mesh-binding shaft is rotatably connected between the lid and the laying box. A common groove for the mesh-binding shaft to rotate is formed between the lid and the laying box. A fixing member is provided between the lid and the laying box for fixation. A covering net is wound around the mesh-binding shaft. The covering net is made of a green and biodegradable material and has several seeds. The laying box is equipped with a cutting component and a binding component. The cutting component is used to cut the covering net, and the binding component is used to fix the laying box to the back of a worker.
[0010] By adopting the above technical solution, workers first install the bundled netting with the covering netting wound inside the laying box. Then, the box cover is used to constrain the bundled netting to the laying box using fasteners. After that, workers use body-binding devices to fix the laying box to their backs, while fixing the end of the covering netting that has been unwound from the laying box to the ground. Finally, workers carry the laying box on their backs and walk across the wasteland with piled soil to lay the covering netting. The green covering netting reduces the impact of wasteland on urban beautification. At the same time, over time, on the one hand, the covering netting will gradually degrade, and on the other hand, the seeds on the covering netting will fall onto the soil and grow to green the wasteland, thus reducing pollution to the soil of the wasteland and achieving ecological restoration of the wasteland.
[0011] Optionally, the covering net includes a side strip and a mesh belt, the side strip is located on both sides of the mesh belt, the seeds are arranged on the mesh belt, and the side strip has a plurality of positioning holes along its length.
[0012] By adopting the above technical solution, the side strip improves the structural strength of the mesh belt, reduces the possibility of the mesh belt being torn, and improves the effect of blocking the soil. At the same time, the positioning holes make it convenient for workers to fix the ends of the covering net to the ground. In addition, the positioning holes also facilitate the splicing of two adjacent covering nets.
[0013] Optionally, the fastener includes an anti-detachment hook rotatably mounted on the box cover, the anti-detachment hook being located at both ends of the mesh shaft, the anti-detachment hook having an L-shaped cross-section, and the laying box having a hook groove for accommodating the anti-detachment hook.
[0014] By adopting the above technical solution, after the worker places the mesh bundle shaft on the shaft groove between the laying box and the box cover, the worker rotates the anti-detachment hook on the box cover. Under the action of gravity, the anti-detachment hook hooks onto the hook groove of the laying box, thereby binding the mesh bundle shaft between the laying box and the box cover, which helps to reduce the difficulty of replacing the mesh bundle shaft.
[0015] Optionally, the cutting assembly includes a cutting plate slidably disposed on the box cover, a mounting plate is disposed on the cutting plate, a cutting blade is slidably disposed on the mounting plate along the width direction of the covering net, a cutting groove is provided on the mounting plate for the cutting blade to slide, and an anti-rotation component is provided on the box cover to restrict the sliding of the cutting plate.
[0016] By adopting the above technical solution, when it is necessary to cut the cover net, the worker releases the restriction of the anti-rotation component, then slides the cutting plate so that the cutting plate moves the mounting plate closer to the laying box until the cutting blade presses the cover net tightly onto the laying box. Then the worker pushes the cutting blade, and the sliding cutting blade cuts the cover net.
[0017] Optionally, the anti-rotation component includes guide arc strips disposed on the box cover and located at both ends of the cutting plate. The guide arc strips are provided with arc grooves. The cutting plate is provided with a sliding rod, which slides in cooperation with the arc groove. A compression spring supports the sliding rod and the inner wall of the arc groove on the side of the laying box near the guide arc strip.
[0018] By adopting the above technical solution, the worker pushes the cutting plate, which drives the sliding rod to slide along the arc groove. The sliding rod squeezes the compression spring, causing the compression spring to deform until the mounting plate is close to the laying box. This makes it easier for the worker to cut the covering net. After cutting, the worker releases the cutting plate, the compression spring returns to its original shape, and the sliding rod pushes the cutting plate back to its original position, thereby reducing the impact on the covering net during the unwinding process.
[0019] Optionally, the mounting plate is provided with pressing strips on both sides in the sliding direction of the cutting blade, the pressing strips being used to press the covering net tightly onto the laying box.
[0020] By adopting the above technical solution, the pressure strip reduces the possibility of the cover net shifting, making it easier for the cutting blade to cut the cover net.
[0021] Optionally, the body support includes an elastic shoulder strap and a flexible back pillow disposed on the paving box, the elastic shoulder strap being elastic and used to press the worker's body firmly against the flexible back pillow.
[0022] By adopting the above technical solution, workers wear elastic back straps, which deform and press the worker's back firmly against the flexible back pillow, thereby reducing the possibility of injury to the human body caused by carrying the laying box for a long time.
[0023] Optionally, both ends of the mesh shaft are rotatably provided with rotating ring tubes, which are located in the shaft groove between the box cover and the laying box.
[0024] By adopting the above technical solution, it is convenient to rotate the netting shaft and unwind the covering net.
[0025] In summary, this application includes at least one of the following beneficial technical effects:
[0026] 1. Workers first install the bundled netting with the netting rolled up inside the laying box. Then, the box cover is used to secure the bundled netting to the laying box using fasteners. After that, the laying box is fixed to the worker's back using a binding device. At the same time, the end of the netting that is rolled out of the laying box is fixed to the ground. Finally, the worker carries the laying box and walks through the abandoned land with piled soil to lay the netting. The green netting will reduce the impact of the abandoned land on urban beautification. At the same time, over time, on the one hand, the netting will gradually degrade, and on the other hand, the seeds on the netting will fall onto the soil and grow to green the abandoned land, which reduces the pollution of the soil in the abandoned land and achieves ecological restoration of the abandoned land.
[0027] 2. The side strips improve the structural strength of the mesh belt, reduce the possibility of the mesh belt being torn, and improve the effect of covering the soil. At the same time, the positioning holes make it easy for workers to fix the ends of the covering net to the ground. In addition, the positioning holes also make it easy to splice two adjacent covering nets.
[0028] 3. The worker pushes the cutting plate, which drives the sliding rod to slide along the arc groove. The sliding rod compresses the compression spring, causing the spring to deform until the mounting plate is close to the laying box. This makes it easier for the worker to cut the covering net. After cutting, the worker releases the cutting plate, the compression spring returns to its original shape, and pushes the cutting plate back to its original position through the sliding rod, thereby reducing the impact on the covering net during the unwinding process.

[0032] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.
[0033] This application discloses an ecological restoration structure for urban abandoned land.
[0034] Reference Figure 1An ecological restoration structure for urban wasteland includes a laying box 1, a box cover 2 hinged to the laying box 1, a netting shaft 3 rotatably arranged between the box cover 2 and the laying box 1, and rotating ring tubes 11 coaxially rotatably connected to both ends of the netting shaft 3.
[0035] Reference Figure 1 The cover 2 and the laying box 1 are provided with a shaft groove 4 for the mesh shaft 3 to rotate. The rotating ring tube 11 is located at the shaft groove 4 between the cover 2 and the laying box 1. The shaft groove 4 of the cover 2 is provided with a chamfer 12 to avoidance.
[0036] Reference Figure 2 A fixing member 5 is arranged between the cover 2 and the laying box 1 for fixing. The fixing member 5 includes an anti-detachment hook 51 rotatably connected to the cover 2. The anti-detachment hook 51 is located at both ends of the netting shaft 3. The cross-section of the anti-detachment hook 51 is L-shaped. The laying box 1 is provided with a hook groove 52 for accommodating the anti-detachment hook 51. The L-shaped end of the anti-detachment hook 51 is hooked into the hook groove 52.
[0037] Reference Figure 1 A covering net 6 is wound around the net shaft 3. The covering net 6 is made of green and biodegradable material, such as the fully biodegradable mulch film in the prior art. The covering net 6 includes a side strip 61 and a net strip 62. The side strip 61 is integrally formed on both sides of the net strip 62. Several seeds 7 are adhered to the net strip 62. The seeds 7 can be fixed to the net strip 62 using bio-based biodegradable adhesive in the prior art. Several positioning holes 63 are opened on the side strip 61 along its length direction.
[0038] Reference Figure 1 The laying box 1 is provided with a body binding member 9, which is used to fix the laying box 1 to the back of the worker. The body binding member 9 includes an elastic back strap 91 and a flexible back pillow 92 that are bonded to the laying box 1. The elastic back strap 91 is elastic and is used to press the worker's body tightly onto the flexible back pillow 92. The flexible back pillow 92 may be made of sponge material.
[0039] The worker rotates the anti-detachment hook 51 on the box cover 2, then rotates and opens the box cover 2. After that, the bundle shaft 3 with the covering net 6 wound around it is placed in the shaft groove 4 on the laying box 1. After pulling the covering net 6 outside the laying box 1, the worker rotates the box cover 2 to press the rotating ring tube 11 at the end of the bundle shaft 3 between the box cover 2 and the laying box 1.
[0040] Finally, rotate the anti-detachment hook 51 to fix the box cover 2 onto the laying box 1. The worker then fixes the covering net 6 to the ground through the positioning hole 63, and then carries the laying box 1 to the soil accumulation area, so that the covering net 6 is laid on the soil.
[0041] Reference Figure 1A cutting component 8 is arranged on the laying box 1. The cutting component 8 is used to cut the covering net 6. The cutting component 8 includes a cutting plate 81 that is slidably arranged on the box cover 2. An installation plate 82 is integrally formed on the cutting plate 81. A cutting blade 83 is slidably arranged on the installation plate 82 along the width direction of the covering net 6.
[0042] Reference Figure 1 and Figure 2 The mounting plate 82 has a cutting groove 84 for the cutting blade 83 to slide. On both sides of the mounting plate 82 in the direction of the cutting blade 83, there are pressing strips 10. The pressing strips 10 can be made of rubber material. The pressing strips 10 are used to press the covering net 6 onto the laying box 1. The box cover 2 is provided with anti-rotation parts 85 to limit the sliding of the cutting plate 81.
[0043] Reference Figure 2 The anti-rotation component 85 includes guide arc strips 851 welded to the box cover 2 and located at both ends of the cutting plate 81. The guide arc strips 851 are provided with arc grooves 852. Two sliding rods 853 are welded to the cutting plate 81. The sliding rods 853 correspond one-to-one with the guide arc strips 851. The sliding rods 853 and the arc grooves 852 are slidably engaged. A compression spring 854 supports the sliding rods 853 and the inner wall of the arc groove 852 on the side of the guide arc strip 851 near the side where the box 1 is laid.
[0044] When the covering net 6 needs to be cut, the worker pushes the cutting plate 81. The cutting plate 81 drives the sliding rod 853 to slide along the arc groove 852. The sliding rod 853 squeezes the compression spring 854, and the compression spring 854 deforms. The cutting plate 81 drives the mounting plate 82 to approach the laying box 1 until the pressing strip 10 abuts against the laying box 1.
[0045] At this time, the cutting blade 83 presses the covering net 6 firmly onto the laying box 1. Then the worker pushes the cutting blade 83, and the sliding cutting blade 83 cuts the covering net 6. After the cutting is completed, the worker releases the cutting plate 81, the compression spring 854 returns to its deformation and pushes the cutting plate 81 back to its original position through the sliding rod 853, and the cutting blade 83 moves away from the covering net 6.
[0046] As time goes on, the covering net 6 gradually degrades, and the seeds 7 stuck to the covering net 6 fall onto the soil. At the same time, rainwater will also cause the seeds 7 stuck to the covering net 6 to fall onto the soil. The covering net 6 will gradually disappear, and the seeds 7 will grow on the soil and green the soil, thereby achieving ecological restoration of the abandoned land.
[0047] The implementation principle of an ecological restoration structure for urban wasteland in this application embodiment is as follows: the worker rotates the anti-detachment hook 51 on the box cover 2, then rotates and opens the box cover 2, and then places the bundled net shaft 3 with the covering net 6 wound around it in the shaft groove 4 on the laying box 1. After pulling the covering net 6 outside the laying box 1, the worker rotates the box cover 2 to press the rotating ring tube 11 at the end of the bundled net shaft 3 between the box cover 2 and the laying box 1.
[0048] Finally, rotate the anti-detachment hook 51 to fix the box cover 2 onto the laying box 1. The worker then fixes the covering net 6 to the ground through the positioning hole 63, and then carries the laying box 1 to the soil accumulation area, so that the covering net 6 is laid on the soil.
[0049] When the covering net 6 needs to be cut, the worker pushes the cutting plate 81. The cutting plate 81 drives the sliding rod 853 to slide along the arc groove 852. The sliding rod 853 squeezes the compression spring 854, and the compression spring 854 deforms. The cutting plate 81 drives the mounting plate 82 to approach the laying box 1 until the pressing strip 10 abuts against the laying box 1.
[0050] At this time, the cutting blade 83 presses the covering net 6 firmly onto the laying box 1. Then the worker pushes the cutting blade 83, and the sliding cutting blade 83 cuts the covering net 6. After the cutting is completed, the worker releases the cutting plate 81, the compression spring 854 returns to its deformation and pushes the cutting plate 81 back to its original position through the sliding rod 853, and the cutting blade 83 moves away from the covering net 6.
[0051] As time goes on, the covering net 6 gradually degrades, and the seeds 7 stuck to the covering net 6 fall onto the soil. At the same time, rainwater will also cause the seeds 7 stuck to the covering net 6 to fall onto the soil. The covering net 6 will gradually disappear, and the seeds 7 will grow on the soil and green the soil, thereby achieving ecological restoration of the abandoned land.
[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
