Abstract
Description
Technical Field
[0001] This application relates to the field of landscape engineering technology, and in particular to a cofferdam and sand control construction system for protecting seedlings in desertification control. Background Technology
[0002] The disadvantages of traditional sand control dikes include:
[0003] 1. Heavy weight, making transportation and installation difficult:
[0004] High transportation costs: Traditional sand control cofferdams mostly use heavy materials such as concrete and stones, which are extremely heavy. In desert areas, transportation is inconvenient and means of transport are often limited. Transporting these heavy cofferdams requires a lot of manpower, material resources, and financial resources. For example, transporting a 10-meter-long concrete cofferdam may require large trucks, and the transportation process may be inefficient due to rugged roads and soft sand, further increasing transportation costs.
[0005] High installation difficulty: Due to their heavy weight, installing traditional cofferdams requires large machinery and a significant amount of manpower. In desert environments, the access and use of large machinery are subject to numerous restrictions, and the installation process is complex, requiring specialized technicians to operate, resulting in a long installation cycle and impacting the progress of desertification control efforts. For example, installing a section of a stone cofferdam requires first transporting the stones to the designated location, then stacking and securing them, a time-consuming and labor-intensive process.
[0006] 2. Non-degradable, easily causing ecological pollution:
[0007] Long-term residue: Traditional cofferdam materials such as plastics and metals are difficult to degrade in the natural environment and will remain in the desert for a long time. These residues not only damage the natural landscape of the desert, but may also affect the structure and properties of the soil. For example, plastic cofferdams in the soil can hinder the infiltration of water and nutrients, affect the growth of plant roots, and lead to a decline in soil fertility.
[0008] Harmful to organisms: Non-degradable dike materials may be ingested by wild animals in the desert, harming their health. At the same time, these materials may release harmful substances, polluting soil and water sources and affecting the balance of the entire ecosystem. For example, metal dikes may rust under wind and sun, releasing heavy metal ions that pollute soil and groundwater, thus affecting desert plants and animals.
[0009] 3. Lacks flexibility and is difficult to adapt to complex terrain:
[0010] Fixed Shape: Traditional sand control dikes typically have a fixed shape and size, making it difficult to adjust to changes in desert terrain. In deserts, the terrain is complex and varied, with dunes, gullies, etc. Fixed-shaped dikes cannot conform well to the terrain, easily creating gaps that allow wind and sand to infiltrate, failing to effectively protect seedlings. For example, installing a traditional square dike on a steep dune will create large gaps between the dike and the dune, allowing wind and sand to easily enter and affecting seedling growth.
[0011] Difficult to Expand: When the desertification control area expands or the layout of the cofferdam needs to be adjusted, the expansion and modification of traditional cofferdams are extremely difficult. It requires dismantling the existing cofferdams and rebuilding new ones, which not only increases costs but also wastes time and resources. For example, if the originally planned desertification control area needs to be expanded, but the traditional cofferdams have already been installed, expanding the protection area requires dismantling part of the cofferdams and rebuilding new ones. This construction process is cumbersome and causes secondary damage to the surrounding environment.
[0012] 4. High maintenance costs:
[0013] Vulnerable to damage: Traditional sand control cofferdams are easily damaged by wind and sand erosion, temperature changes, and other factors in the harsh environment of the desert. For example, concrete cofferdams will develop wear and cracks on their surface under long-term wind and sand blowing; metal cofferdams are prone to rust and corrosion under high temperatures and dust. Once a cofferdam is damaged, it needs to be repaired in time, otherwise its protective effect will be compromised.
[0014] Maintenance is complex: Repairing traditional cofferdams requires specialized technology and equipment, resulting in high costs. Furthermore, the difficult transportation in desert areas hinders the transport of personnel and materials, further increasing the complexity and cost of repairs. For example, repairing a damaged section of concrete cofferdam requires dismantling the damaged part and then re-pouring concrete. This entire process consumes significant time and manpower, and repair materials must be transported from afar, further increasing costs. Utility Model Content

[0035] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present application will become clearer and more apparent.
[0036] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments. Although various aspects of embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated otherwise.
[0037] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0038] To facilitate understanding of the sand control seedling protection cofferdam and sand control construction system provided in this application embodiment, its application scenario will be explained first. The sand control seedling protection cofferdam and sand control construction system provided in this application embodiment is used to achieve lightweight, biodegradable isolation zones, and achieves rapid assembly through modular design. The disadvantages of traditional sand control cofferdams are: 1. Heavy weight, difficult transportation and installation: High transportation costs: Traditional sand control cofferdams mostly use heavy materials such as concrete and stones, which are extremely heavy. In desert areas, transportation is inconvenient, and transportation vehicles are often limited. Transporting these heavy cofferdams requires a lot of manpower, material resources, and financial resources. For example, transporting a 10-meter-long concrete cofferdam may require the use of large trucks, and the transportation process may be inefficient due to rugged roads, soft sand, etc., increasing transportation costs. High installation difficulty: Due to the heavy weight, installing traditional cofferdams requires large machinery and a lot of manpower. In the desert environment, the entry and use of large machinery are subject to many restrictions, and the installation process is complex, requiring professional technicians to operate, and the installation cycle is long, affecting the progress of sand control work. For example, installing a section of stone cofferdam requires transporting the stones to the designated location before stacking and securing them, a time-consuming and labor-intensive process. 2. Non-degradable, prone to ecological pollution: Long-term residue: Traditional cofferdam materials such as plastic and metal are difficult to degrade in the natural environment and will remain in the desert for a long time. These residues not only damage the natural landscape of the desert but may also affect the structure and properties of the soil. For example, plastic cofferdams in the soil can hinder the penetration of water and nutrients, affecting the growth of plant roots and leading to a decline in soil fertility. Harm to organisms: Non-degradable cofferdam materials may be accidentally ingested by wild animals in the desert, harming their health. At the same time, these materials may also release harmful substances, polluting the soil and water sources and affecting the balance of the entire ecosystem. For example, metal cofferdams may rust under wind and sun, releasing heavy metal ions, polluting the soil and groundwater, and thus affecting desert plants and animals. 3. Lack of flexibility, difficult to adapt to complex terrain: Fixed shape: The shape and size of traditional desertification control cofferdams are usually fixed, making it difficult to adjust them according to changes in desert terrain. In deserts, the terrain is complex and varied, with dunes and gullies. Fixed-shape cofferdams cannot conform well to the terrain, easily creating gaps that allow wind and sand to infiltrate, failing to effectively protect seedlings. For example, installing a traditional square cofferdam on a steep dune creates large gaps between the cofferdam and the dune, allowing wind and sand to easily enter and hinder seedling growth. Furthermore, traditional cofferdams are difficult to expand: when the desertification control area expands or the cofferdam layout needs adjustment, expanding and modifying them is extremely difficult. Existing cofferdams must be demolished and new ones rebuilt, increasing costs and wasting time and resources. For instance, if the planned desertification control area needs to be expanded, but the traditional cofferdam has already been installed, expanding the protection area requires demolishing part of the cofferdam and rebuilding a new one, a cumbersome construction process that causes secondary damage to the surrounding environment.4. High Maintenance Costs: Traditional sand control cofferdams are easily damaged by wind and sand erosion and temperature changes in the harsh desert environment. For example, concrete cofferdams will develop wear and cracks under long-term wind and sand erosion; metal cofferdams are prone to rust and corrosion under high temperatures and dust. Once a cofferdam is damaged, it needs to be repaired promptly, otherwise its protective effect will be affected. Complex Maintenance: Repairing traditional cofferdams requires specialized technology and equipment, resulting in high maintenance costs. Furthermore, the inconvenient transportation in desert areas makes it difficult to transport maintenance personnel and materials, further increasing the difficulty and cost of maintenance. For example, repairing a damaged section of concrete cofferdam requires dismantling the damaged part and then re-pouring concrete. The entire repair process consumes a lot of time and manpower, and repair materials also need to be transported from a distance, increasing maintenance costs. Therefore, this application provides a sand control cofferdam and sand control construction system for protecting seedlings, achieving lightweight, biodegradable isolation zones, and enabling rapid assembly through modular design. The following detailed description, in conjunction with specific accompanying drawings, illustrates the embodiments.
[0039] refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a cofferdam for protecting seedlings in desertification control, provided in an embodiment of this application. Figure 2 A schematic diagram of the connection structure of the cofferdam for protecting seedlings in desertification control provided in the embodiments of this application.
[0040] exist Figure 1 and Figure 2 In this application embodiment, a cofferdam for protecting seedlings in desertification control is provided, comprising multiple L-shaped isolation strip bodies, connecting components, and fixing parts, wherein,
[0041] The connecting component is used to connect adjacent L-shaped isolation strip bodies;
[0042] The fastener is used to secure the L-shaped isolation strip body.
[0043] In the above technical solution, by setting multiple L-shaped isolation belt bodies, connecting components and fasteners, the connecting components are used to connect adjacent L-shaped isolation belt bodies; the fasteners are used to fix the L-shaped isolation belt bodies; a lightweight and biodegradable isolation belt is achieved, and rapid assembly is realized through modular design.
[0044] Specifically, the beneficial effects of the dike used for protecting seedlings in desertification control include:
[0045] Advantages of lightweight design
[0046] Easy to transport and carry: The lightweight L-shaped isolation barrier significantly reduces the overall weight. In desertification control work, personnel often need to venture deep into remote areas such as deserts, where transportation options may be limited. The lightweight isolation barrier can be easily loaded onto small vehicles, camels, or even manual transport tools, reducing transportation costs and manpower consumption, and enabling desertification control materials to be delivered to the site more quickly and efficiently.
[0047] Reduced installation difficulty: The lighter weight makes assembling the cofferdam easier for installers, eliminating the need for large lifting equipment or excessive physical exertion. Installation can be completed by a single person or a small group, improving efficiency, especially in the harsh conditions of desert regions. This reduces the workload of installers and helps accelerate desertification control efforts.
[0048] Reduced pressure on the soil: The lightweight design reduces the pressure of the cofferdam on the soil below, preventing soil compaction due to its own weight, which could affect the respiration and growth of seedling roots. At the same time, it helps maintain the loose structure of the soil, promoting water infiltration and downward root extension, creating a favorable growing environment for the seedlings.
[0049] Advantages of biodegradable properties
[0050] Environmentally friendly and pollution-free: Biodegradable cofferdam materials can gradually decompose in the natural environment, unlike traditional non-biodegradable materials such as plastics, which leave long-term residues and pollute the soil, water sources, and ecological environment. In desertification control areas, maintaining the cleanliness and stability of the ecological environment is crucial, and the use of biodegradable cofferdams helps maintain the balance of desert ecosystems and promotes the restoration of biodiversity.
[0051] Avoiding secondary cleanup: Traditional cofferdams require dismantling and cleaning after use, which not only increases manpower and material costs but may also damage newly restored vegetation. Biodegradable cofferdams, after fulfilling their function of protecting seedlings, will naturally decompose and integrate into the soil, eliminating the need for secondary cleanup, reducing disturbance to desertification control areas, and contributing to the sustainable improvement of the ecological environment.
[0052] Providing nutrients: Some biodegradable materials release organic matter and nutrients during decomposition, providing additional nutritional support to the soil and seedlings. These nutrients can improve soil fertility, promote seedling growth and development, increase seedling survival rate and stress resistance, and further enhance the desertification control effect.
[0053] Advantages of modular design
[0054] Rapid Assembly: The modular design makes cofferdam assembly simple and quick. Adjacent L-shaped isolation strips are connected via connecting components, eliminating the need for complex construction techniques and specialized skills. Installers can quickly complete the cofferdam construction. In desertification control, time is of the essence; rapid cofferdam assembly provides timely protection for seedlings, reducing wind and sand damage.
[0055] Flexible Adjustment: The modular design allows for flexible adjustment of the shape and size of the cofferdam according to the terrain and needs of the actual desertification control area. Whether the area is a regular square or an irregular shape, it can be achieved by combining different numbers and orientations of L-shaped isolation strips. This flexibility enables the cofferdam to better adapt to various complex desertification control environments, improving the targeting and effectiveness of desertification control work.
[0056] Easy to maintain and replace: If a part of the cofferdam is damaged during use, the modular design makes maintenance and replacement very convenient. Simply remove the damaged L-shaped isolation strip and replace it with a new part; there is no need to dismantle and rebuild the entire cofferdam, reducing maintenance and time costs and ensuring the cofferdam's continuous protective function.
[0057] In one specific implementation scheme, the L-shaped isolation strip body includes a horizontal wing plate 2 and a vertical baffle 1, wherein,
[0058] The horizontal wing plate and the vertical baffle are connected.
[0059] In one possible implementation, the horizontal wing includes a plurality of horizontal toothed plates.
[0060] In one specific implementation scheme, the horizontal toothed plate is provided with pre-drilled holes.
[0061] The reserved hole is installed with the fastener.
[0062] In one specific implementation, the vertical baffle is provided with fastening holes at both ends, and the fastening holes are connected to the connecting assembly.
[0063] In one possible implementation, the connecting assembly includes a retaining plate 4 and a screw 3.
[0064] In one possible implementation, the fastener includes a shrub branch 5.
[0065] In one specific implementation scheme, the L-shaped isolation strip body is integrally stamped.
[0066] In one specific implementation, the L-shaped isolation strip body is made of straw.
[0067] This application provides a desertification control construction system, including any of the aforementioned cofferdams for protecting seedlings during desertification control.
[0068] In the above technical solution, by setting multiple L-shaped isolation belt bodies, connecting components and fasteners, the connecting components are used to connect adjacent L-shaped isolation belt bodies; the fasteners are used to fix the L-shaped isolation belt bodies; a lightweight and biodegradable isolation belt is achieved, and rapid assembly is realized through modular design.
[0069] Specifically, the dike for protecting seedlings in desertification control includes: an L-shaped isolation strip body, connecting components, and fixing parts; fastening holes are opened on both sides of the isolation strip, and adjacent isolation strips are fixed together by the connecting components, and the isolation strips are fixed in the green space by shrub branches, so that multiple isolation strips can be arranged into any shape.
[0070] Furthermore, the main structure is formed by stamping, and the cross-section is L-shaped (horizontal wing plate + vertical baffle).
[0071] Furthermore, the horizontal wing plate is toothed, with each tooth having a pre-drilled hole (150mm spacing) to be fixed to the green ground by fasteners and shrub branches.
[0072] Furthermore, pre-drilled holes are provided on both sides of the vertical baffle to connect the connected isolation strip bodies together using connecting components (fixing plates, screws).
[0073] The advantages of the above technical solution include: it can be customized, easy and quick to install, long service life, durable and corrosion resistant, and can be bent at will, allowing multiple isolation strips to be combined into any shape.
