[0002] Traditional sleepers are mainly made of wood or concrete materials. Although wooden sleepers are naturally environmentally friendly, they have poor durability, are prone to decay and insect infestation, and have high maintenance costs. Concrete sleepers are more durable, but they are heavy, difficult to handle and install, and cause relatively large environmental pollution during the production process.
[0003] Currently, some sleepers made of polymer composite materials have begun to be applied. These sleepers attempt to achieve a balance between durability and environmental friendliness, but they often have high costs or still lack comprehensive performance. Utility Model Content
[0004] In view of the deficiencies of the prior art, this application provides an environmentally friendly sleeper made of bamboo-based fiber composite materials, which has the advantages of being both environmentally friendly and durable and having a relatively low cost, and solves the problems raised in the background art.
[0005] To achieve the above object, this application provides the following technical solution: An environmentally friendly sleeper made of bamboo-based fiber composite materials, including a sleeper body, the sleeper body is made of a mixture of bamboo fiber and an environmentally friendly resin through a hot pressing process, and the cross-section of the sleeper body is an I-shaped structure;
[0006] The sleeper body includes an upper wing plate, a lower wing plate and a web;
[0007] The top and bottom cross-sections of the web are symmetrically arranged triangles;
[0008] The upper surfaces of the left and right ends of the lower wing plate are both inclined downward and symmetrically arranged;
[0009] Two groups of drainage grooves are opened at the left and right ends of the lower wing plate.
[0010] Through the above solution, by using bamboo fiber as the main constituent material, bamboo, as a fast-growing renewable resource, not only reduces the dependence on natural resources, but also significantly reduces environmental pollution during the production and use processes. By adding reinforcing fibers such as carbon fiber or glass fiber to the bamboo-based fiber, the mechanical properties and durability of the sleeper are effectively improved, enabling it to better cope with heavy loads and harsh environmental conditions, extending the service life and reducing the maintenance cost. Through the inclined downward V-shaped drainage grooves on the lower wing plate and the filter sheet provided at the top, the drainage efficiency of the sleeper is greatly improved, effectively preventing the corrosion of the sleeper caused by water accumulation, and further ensuring the long-term use effect of the sleeper. The wear-resistant and anti-corrosion coating covering the outer surface of the sleeper body effectively resists the erosion of the external environment, such as rainwater, dust, chemical substances, etc., protects the internal structure of the sleeper, and extends the overall service life.
[0011] Furthermore, the sleeper body further includes reinforcing fibers, and the reinforcing fibers are carbon fibers or glass fibers.
[0012] Through the above solution, the durability and load-bearing capacity of the sleeper can be enhanced.
[0013] Furthermore, the drainage groove of each lower wing plate is designed as an inclined downward V-shaped structure.
[0014] Through the above solution, the discharge of rainwater can be accelerated, and the corrosion of the sleeper caused by accumulated water can be reduced.
[0015] Furthermore, the outer surfaces of the upper wing plate, lower wing plate and web of the sleeper body are all covered with a wear-resistant and anti-corrosion coating.
[0016] Through the above solution, the sleeper can be protected from the erosion of the external environment, its service life can be extended, and the aesthetic appearance can be maintained.
[0017] Furthermore, the environmentally friendly resin can be replaced with a bio-based resin or a degradable resin.
[0018] Through the above solution, the sustainability of the sleeper can be improved, and the performance and cost of the sleeper can be adjusted according to actual needs.
[0019] Furthermore, the edges of the sleeper body are all rounded.
[0020] Through the above solution, the stress concentration phenomenon that may occur during transportation, installation and use can be reduced, and the durability and safety of the sleeper can be improved.
[0021] Furthermore, a filter sheet is fixedly connected to the top end of the inner wall of each drainage groove.
[0022] Through the above solution, the setting of the drainage groove further improves the overall drainage performance, and at the same time, the filter sheet can effectively prevent the drainage groove from being blocked.
[0023] Furthermore, anti-slip textures are provided on the top of the upper wing plate.
[0024] Through the above solution, the friction force with the rail can be increased, and the track stability can be improved.
[0025] Compared with the prior art, the technical solution of the present application has the following beneficial effects:
[0026] The environmentally friendly sleeper made of bamboo-based fiber composite material uses bamboo fiber as the main constituent material. As a rapidly renewable resource, bamboo not only reduces the dependence on natural resources but also significantly reduces environmental pollution during production and use. By adding reinforcing fibers such as carbon fiber or glass fiber to the bamboo-based fiber, the mechanical properties and durability of the sleeper are effectively improved, enabling it to better cope with heavy loads and harsh environmental conditions, extending its service life, and reducing maintenance costs. The V-shaped drainage grooves that slope downward on the lower wing plate and the filter sheet provided at the top greatly improve the drainage efficiency of the sleeper, effectively preventing water accumulation from corroding the sleeper and further ensuring the long-term use effect of the sleeper. The wear-resistant and anti-corrosion coating covering the outer surface of the sleeper body effectively resists the erosion of the external environment, such as rain, sand, and chemical substances, protecting the internal structure of the sleeper and extending the overall service life.
