Description

Technical Field

[0001] This application relates to the field of power pole technology, specifically to a method of preparing cement power poles from solid waste. Background Technology

[0002] As a crucial component of power transmission and distribution systems, utility poles bear the vital responsibility of erecting transmission lines and ensuring power transmission. Cement poles, due to their simple manufacturing process, good strength, and high durability, are widely used in power systems. However, traditional cement poles still have some shortcomings in practical applications. Cement poles are typically constructed of reinforced concrete, primarily made of cement, sand, gravel, and reinforcing steel. Due to factors such as concrete shrinkage, temperature changes, and external impacts, cement poles are prone to cracking, affecting their structural safety and service life. The base, in particular, suffers from poor stability, lacking sufficient bending and torsional resistance, making it susceptible to tipping or breakage under stress during use. Furthermore, their overall corrosion resistance is poor, making them prone to damage in harsh environments. This not only affects the safe and stable operation of the power system but also increases the maintenance costs of cement poles. Utility Model Content

[0003] The purpose of this invention is to provide a method for preparing cement poles from solid waste. By utilizing the functionality of solid waste materials to replace some additives, the performance of cement is improved, thereby enhancing the strength, durability, and corrosion resistance of the cement pole's root, increasing the service life of the cement pole, and reducing maintenance costs.

[0004] This application is achieved through the following technical solution, specifically:

[0005] A cement pole made from solid waste includes a cement pole body and a support base connected to the root of the cement pole body, wherein the support base is made of solid waste cement-based material.

[0006] In this solution, the support base for cement poles is prepared using solid waste-based cement materials. Due to the inherent functional properties of solid waste materials, such as the reactivity of pozzolanic ash, they can replace traditional additives to improve the performance of cement, thereby enhancing the strength and durability of the support base and ensuring the stability and reliability of the cement poles under various environmental conditions. Simultaneously, this solution also achieves the resource utilization of solid waste, reducing the production and maintenance costs of cement poles.

[0007] As an improvement to the support base in this application, the support base has an "I" shaped structure and includes a corrosion-resistant part, a load-bearing part, and an anti-settlement part arranged sequentially from top to bottom.

[0008] In this design, the "I"-shaped structure significantly improves the overall stability of the support base, enhances its bending and shear resistance, and enables it to maintain good load-bearing performance even under complex geological conditions. The anti-corrosion section enhances the corrosion resistance of the base and extends its service life. The load-bearing section bears the main load and ensures the stable support of the pole. The anti-settlement section further enhances the base's anti-settlement capability. The synergistic effect of these multiple structures significantly improves the overall safety and reliability of the pole.

[0009] Furthermore, the load-bearing part is a hollow column, and the load-bearing part includes a seismic isolation layer, a transition layer disposed on the inner surface of the seismic isolation layer, and a high-strength layer disposed on the inner surface of the transition layer, wherein a steel cage is disposed in the high-strength layer.

[0010] Furthermore, the material of the vibration isolation layer is a solid waste cement-based material mixed with rubber particles.

[0011] Furthermore, the transition layer is made of a solid waste cement-based material mixed with fibers, wherein the fibers include one or more of steel fibers, polypropylene fibers, or basalt fibers.

[0012] As another improvement to the support base in this application, the upper surface of the anti-corrosion part has a horizontal surface and a downward inclined surface. The horizontal surface is connected to the bottom of the cement pole, and the inclined surface is inclined from the inside to the outside. The surface of the anti-corrosion part is coated with a siloxane coating.

[0013] Furthermore, the material of the anti-corrosion part is a solid waste cement-based material mixed with fly ash or slag powder.

[0014] As another improvement to the support base in this application, the anti-settlement part is made of a solid waste cement-based material mixed with at least one of rice husk ash, silica fume or red mud.

[0015] The beneficial effects of this application are as follows:

[0016] 1. The present application proposes a solution that utilizes solid waste-based cement materials to prepare the support base for cement poles. Due to the inherent functional characteristics of solid waste materials, such as the reactivity of pozzolanic ash, they can replace traditional additives to improve the performance of cement, thereby enhancing the strength and durability of the support base and ensuring the stability and reliability of the cement poles under various environmental conditions. Simultaneously, this solution also achieves the resource utilization of solid waste, reducing the production and maintenance costs of cement poles.

[0017] 2. The solution proposed in this application significantly improves the overall stability of the support base through the "I"-shaped structure, enhancing its bending and shear resistance, and enabling it to maintain good load-bearing performance under complex geological conditions. The anti-corrosion part enhances the corrosion resistance of the base and extends its service life. The load-bearing part bears the main load, ensuring the stable support of the pole. The anti-settlement part further enhances the anti-settlement capability of the base. The synergistic effect of multiple structures significantly improves the overall safety and reliability of the pole.

[0024] The following will be combined with the appendix Figures 1-3 The embodiments of the technical solution of this application are described in detail below. The following embodiments are only used to more clearly illustrate the technical solution of this application, and are therefore merely examples and should not be used to limit the scope of protection of this application. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] In view of the problems existing in the background technology or products, Figure 1 A schematic diagram of a solid waste-based cement pole preparation method according to an embodiment of this application is shown, as follows: Figure 1 As shown in the figure, this application provides a cement pole made from solid waste, including a cement pole body 1 and a support base 2 connected to the root of the cement pole body 1. The support base 2 is made of solid waste cement-based material.

[0026] Specifically, the bottom of the cement pole 1 is fixedly connected to the surface of the support base by a plurality of studs arranged circumferentially. The solid waste cement-based material is made by mixing solid waste materials and cement. The solid waste materials include, but are not limited to, one or more of fly ash, silica fume, slag, steel slag, rubber, fiber, tailings, phosphogypsum, red mud, glass powder, ceramic powder, and biomass ash. Due to the functional characteristics of the solid waste materials themselves, such as the activity of volcanic ash, they can replace traditional additives to improve the performance of cement, thereby enhancing the strength and durability of the support base and ensuring the stability and reliability of the cement pole under various environmental conditions.

[0027] It should be noted that the solid waste materials need to be pretreated before mixing. Pretreatment can remove substances that may have an adverse effect on cement performance, such as heavy metals and sulfides, and can also ensure that the particle size distribution of the solid waste materials and cement is uniform.

[0028] Figure 2 This is a front view of a method for preparing cement poles from solid waste, as described in an embodiment of this application. Figure 2 As shown, in one implementation, the support base 2 has an "I" shaped structure, and the support base 2 includes a corrosion-resistant part 21, a load-bearing part 22 and an anti-settlement part 23 arranged sequentially from top to bottom.

[0029] Specifically, the "I"-shaped structure design provides better stability and load-bearing capacity. In this embodiment, the corrosion-resistant part 21 is installed above the ground, while the load-bearing part 22 and the anti-settlement part 23 are both installed below the ground.

[0030] The anti-corrosion part 21 is located at the uppermost end of the support base 2 and is directly connected to the bottom of the cement pole 1. Its main function is to prevent corrosion at the connection between the bottom of the cement pole 1 and the support base 2. In one implementation, the upper surface of the anti-corrosion part 21 has a horizontal surface and a downward inclined surface. The horizontal surface is connected to the bottom of the cement pole 1, and the inclined surface is inclined from the inside to the outside. The surface of the anti-corrosion part 21 is coated with a siloxane coating.

[0031] Specifically, the inclined surface slopes from the inside out, effectively guiding rainwater and moisture to flow naturally to the outside, preventing moisture from accumulating at the connection between the anti-corrosion part 21 and the cement pole 1, thereby reducing the risk of moisture penetration and corrosion to the cement pole 1. The siloxane coating has excellent hydrophobic properties, further protecting the connection from corrosion.

[0032] Preferably, the anti-corrosion part 21 is made of solid waste cement-based material mixed with fly ash or slag powder. Fly ash and slag powder have pozzolanic activity and can undergo a secondary hydration reaction with calcium hydroxide in cement hydration products to generate hydrated calcium silicate with cementitious properties, thereby improving the density and strength of the cement-based material, while reducing the calcium hydroxide content generated during cement hydration, reducing the alkalinity of the cement-based material, and improving its corrosion resistance.

[0033] The anti-settlement section 23 is located below the bearing section 22 and is the part of the support base 2 that contacts the foundation. Its main function is to prevent the cement pole from tilting or collapsing due to foundation settlement. In one implementation, the anti-settlement section 23 is made of a solid waste cement-based material mixed with at least one of rice husk ash, silica fume, or red mud.

[0034] Specifically, rice husk ash, silica fume, or red mud all contain active substances that can react with cement hydration products, such as active silica, active alumina, and silica. Solid waste cement-based materials containing at least one of rice husk ash, silica fume, or red mud have better strength and density, reducing concrete shrinkage and thus reducing the risk of settlement.

[0035] Figure 3 A cross-sectional view of the support portion in an embodiment of this application is shown, such as... Figure 3 As shown, the bearing part 22 is a hollow column. The bearing part 22 includes a vibration isolation layer 221, a transition layer 222 disposed on the inner surface of the vibration isolation layer 221, and a high-strength layer 223 disposed on the inner surface of the transition layer 222. A steel cage is disposed in the high-strength layer 223.

[0036] Specifically, the load-bearing section 22 consists of a three-layer structure, from the outside to the inside: a seismic isolation layer 221, a transition layer 222, and a high-strength layer 223. This multi-layer structure design can fully utilize the performance advantages of different materials and improve the overall performance of the load-bearing section 22. The high-strength layer 223 is located on the inner surface of the transition layer 222 and is the main load-bearing structure of the load-bearing section 22. It is made of high-strength concrete and has a steel cage inside. It has high compressive strength and can withstand the weight of the concrete pole and wind load.

[0037] Preferably, the isolation layer 221 is made of solid waste cement-based material mixed with rubber particles. The isolation layer 221 is located on the outermost layer of the load-bearing part 22. The addition of rubber particles can improve the flexibility and elasticity of the material, absorb seismic waves and impact forces, and reduce damage to the cement pole.

[0038] Preferably, the transition layer 222 is made of a solid waste cement-based material mixed with fibers, wherein the fibers include one or more of steel fibers, polypropylene fibers, or basalt fibers.

[0039] Specifically, the transition layer 222 is located on the inner surface of the seismic isolation layer 221, and its material is a solid waste cement-based material mixed with fibers, including one or more of steel fibers, polypropylene fibers, or basalt fibers. The addition of fibers can improve the tensile strength and crack resistance of the material, and enhance the overall structural strength of the load-bearing part 22.
