Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary equipment technology for engineering construction, and in particular to a temporary surface soil protection device for engineering projects. Background Technology
[0002] During construction, large amounts of temporary land are often required, such as access roads, material storage areas, and temporary office areas. The topsoil of these temporary sites is easily affected by factors such as vehicle traffic, machinery operation, rainwater erosion, and pollution from building materials during construction, leading to problems such as soil structure damage, decreased fertility, and soil erosion. After the project is completed, this damaged topsoil is difficult to restore quickly, not only impacting the surrounding ecological environment but also increasing the difficulty and cost of land reclamation.
[0003] Currently, common methods for protecting the surface soil of temporary construction sites include laying plastic films and tarpaulins. However, these methods have significant drawbacks: plastic films and tarpaulins have low strength and are easily damaged when subjected to construction vehicle pressure or scratches from sharp objects, leading to the failure of soil protection; at the same time, plastic films and tarpaulins are not breathable, which affects gas exchange between the soil and the outside environment, hindering the survival and activity of soil microorganisms, and long-term use can negatively impact soil fertility; furthermore, these materials are difficult to recycle after the project is completed, and some residual materials can cause secondary pollution to the soil. Therefore, we propose a surface soil protection device for temporary construction sites to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to solve the problems of low strength, easy damage and poor air permeability of the surface soil protection methods for temporary engineering land in the existing technology, and to propose a surface soil protection device for temporary engineering land.
[0005] To achieve the above objectives, the present invention employs the following technology: a temporary surface soil protection device for engineering projects, comprising a protective plate body, a fixing frame, and ground nails. The protective plate body is disposed inside the fixing frame, and a connecting component is disposed on the outside of the fixing frame. A notch is provided at the top of the fixing frame, and the ground nails extend through the notch to the bottom. The protective plate body is composed of a base layer, a buffer layer, and a protective layer from bottom to top.
[0006] As a further description of the above technical solution: the connecting component includes a mating block fixed on one side of the fixed frame and a mating slot adapted to be opened on the other side of the fixed frame.
[0007] As a further description of the above technical solution: the base layer is made of biodegradable non-woven fabric.
[0008] As a further description of the above technical solution: the buffer layer is made of elastic rubber particles and high molecular polymer mixed and pressed, with a thickness of 3-5mm, and the buffer layer is provided with multiple honeycomb-shaped air pores, which penetrate through the upper and lower surfaces of the buffer layer.
[0009] As a further description of the above technical solution: the protective layer is made of high-strength polyethylene material with a thickness of 2-3mm.
[0010] As a further description of the above technical solution: the top of the protective layer is provided with anti-slip protrusions, and the surface of the protective layer is sprayed with an anti-ultraviolet coating to improve the anti-aging performance of the protective layer and extend the service life of the device.
[0011] As a further description of the above technical solution: the protective plate body is provided with several water seepage holes.
[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: This utility model features a protective panel body composed of a base layer, a buffer layer, and a protective layer. It integrates multiple functions such as water permeability, soil retention, high strength, wear resistance, and anti-aging properties, providing comprehensive and effective soil protection. The base layer, made of biodegradable non-woven fabric, not only acts as a filter to prevent soil particle loss but also degrades naturally after the project, preventing secondary pollution. The buffer layer, made of a mixture of elastic rubber particles and high-molecular polymers with honeycomb-shaped air pores, not only provides excellent cushioning, reducing the pressure on the soil from construction vehicles and preventing soil compaction but also ensures soil permeability, promoting the survival of soil microorganisms. The protective layer, made of high-strength polyethylene with anti-slip protrusions and an anti-UV coating, offers high strength, excellent anti-slip properties, and effective resistance to external scratches and crushing. Its strong anti-aging properties extend the device's lifespan. Multiple protective panels are detachably connected via connecting components, allowing for quick and easy installation and disassembly. This facilitates flexible splicing according to the actual area of temporary land use, improving the device's applicability. Furthermore, after the project, the protective panels can be disassembled and recycled, reducing operating costs. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0016] Reference Figures 1-3 This embodiment provides a temporary surface soil protection device for engineering projects, including a protective plate body 1, a fixing frame 2, and ground nails 6. The protective plate body 1 is disposed inside the fixing frame 2. The protective plate body 1 has several water seepage holes 7, which can accelerate rainwater infiltration during heavy rainfall, prevent water accumulation in the cushion layer, and further enhance air permeability. A connecting component 5 is provided on the outside of the fixing frame 2. The connecting component 5 includes a mating block 51 fixed on one side of the fixing frame 2 and a mating slot 52 adapted to the other side of the fixing frame 2. A buttonhole 3 is provided at the top of the fixing frame 2, and the ground nails 6 extend to the bottom through the buttonhole 3. The protective plate body 1 is composed of a base layer 101, a buffer layer 102, and a protective layer 103 from bottom to top.
[0017] Specifically, in use, the surface of the temporary land is first leveled, then a single protective panel body 1 is laid on the soil surface. Ground nails 6 are inserted into the holes 3 until they are embedded in the soil, thus achieving initial fixation of the single protective panel body 1. Next, adjacent protective panel bodies 1 are brought close together, and the mating blocks 51 on adjacent protective panel bodies 1 are inserted into the mating slots 52 to complete the connection between adjacent protective panel bodies 1. This completes the splicing of two protective panel bodies 1, which is then fixed with ground nails 6. Following this method, multiple protective panel bodies 1 are spliced one by one according to the actual area of the temporary land until the entire surface of the temporary land is covered. Through the filtering of the base layer 101 and... The degradation properties solve the problems of "soil loss and pollution", the pressure reduction and air permeability of the buffer layer 102 solve the problems of "soil compaction and microbial activity", and the wear resistance and anti-slip properties of the protective layer 103 solve the problems of "device durability and construction safety". The combination of the three makes the device not only meet the high-intensity use requirements of temporary engineering sites, but also maximize the protection of the fertility and structure of the topsoil, providing a good foundation for subsequent land restoration. At the same time, it takes into account resource recycling and green environmental protection. After the project is completed, first pull out the ground nails 6, disassemble the connection of the protective plate body 1, and then disassemble the individual protective plate body 1 for cleaning and maintenance so that it can be reused. The base layer 101 can be naturally degraded and does not require additional treatment.
[0018] Furthermore, the base layer 101 is made of biodegradable non-woven fabric.
[0019] Specifically, the base layer 101 uses biodegradable non-woven fabric, with corn starch and plant fibers such as cotton and hemp as the main components, mixed with a small amount of polylactic acid as a reinforcing agent. This ensures that the material can be completely degraded in the natural environment within 6-12 months, and the degradation products are carbon dioxide and water, posing no risk of soil pollution. The top of the base layer 101 is bonded to the buffer layer 102 with environmentally friendly hot melt adhesive. The micron-level pores of the base layer 101 can intercept fine particles, silt, and clay particles in the soil. When rainwater or sprinkler water seeps in, only water is allowed to pass through, preventing particles from being lost with the water and avoiding soil fertility loss. The porous structure ensures gas exchange between the soil and the outside world, allowing oxygen to penetrate to the soil surface. At the same time, the porous structure reduces the direct impact of raindrops on bare soil, preventing soil aggregates from breaking up and reducing the risk of loss from the source. The biodegradable material does not require manual recycling after the project is completed and can naturally degrade with the soil environment, avoiding soil pollution caused by traditional plastic film residues. During the degradation process, it can also replenish a small amount of organic fiber to the soil, slightly improving the soil structure and helping subsequent land restoration.
[0020] Furthermore, the buffer layer 102 is made of elastic rubber particles and high molecular polymer mixed and pressed, with a thickness of 3-5mm. The buffer layer has multiple honeycomb-shaped air pores inside, which penetrate the upper and lower surfaces of the buffer layer to ensure soil permeability.
[0021] Specifically, the buffer layer 102 uses elastic rubber particles as the main raw material, mixed with 20%-30% high molecular polymers, such as polyvinyl alcohol, and PVA as a binder. 5%-8% calcium carbonate powder is added to enhance structural stability, ensuring a balance between buffering performance and durability. The bottom of the buffer layer 102 is bonded to the base layer 101 with EVA hot melt adhesive, and the top is bonded to the protective layer 103 with the same hot melt adhesive. The elastic rubber particles in the buffer layer 102 have excellent deformation recovery ability and high durability. When construction vehicles roll over it, the buffer layer 102 can produce 1-2mm of elastic deformation, dispersing concentrated pressure into uniform pressure, preventing soil compaction due to local high pressure, and maintaining soil permeability and water permeability. The through-hole ventilation holes, together with the pores of the base layer 101 and the soil pores, form a "three-dimensional ventilation network," allowing air to circulate freely between the soil, base layer 101, and buffer layer 102, further ensuring soil microbial activity and preventing the soil from becoming "wet" due to long-term covering, thus reducing mold growth.
[0022] Furthermore, the protective layer 103 is made of high-strength polyethylene material with a thickness of 2-3mm. The top of the protective layer 103 is provided with anti-slip protrusions 4, and the surface of the protective layer 103 is sprayed with an anti-ultraviolet coating to improve the anti-aging performance of the protective layer 103 and extend the service life of the device.
[0023] Specifically, the protective layer 103 uses high-strength polyethylene as the base material to ensure that the material has excellent impact resistance and wear resistance, and can resist external force damage such as scratches and rolling during construction. The high-strength HDPE material can resist scratches from sharp objects during construction. After scratching, only slight scratches will appear on the surface, without damage. At the same time, it can withstand long-term rolling by heavy construction vehicles, effectively protecting the base layer 101 and the buffer layer 102 from external force damage. The anti-ultraviolet coating can absorb more than 90% of ultraviolet rays, slowing down the aging and degradation rate of HDPE material, extending the overall service life of the device, and reducing the frequency and cost of replacement.
[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
