Description

Technical Field

[0001] This utility model relates to a prefabricated eco-friendly high-resistance brick with mortise and tenon structure for use in patrol trails, belonging to the field of power facility construction and ecological environment technology. Background Technology

[0002] In substations, power plants, and other similar locations, inspection walkways are required around equipment areas and structural foundations. To ensure personnel safety during grounding faults, the traditional practice is to lay high-resistivity bricks along the inspection walkways on the grounding grid to suppress step voltage. However, existing high-resistivity bricks have a single function; their dense concrete structure is impermeable and does not promote vegetation growth, exacerbating the heat island effect in the station area, which is inconsistent with the current concept of green power plant construction.

[0003] On the other hand, although ecological concrete technology can achieve greening, its high porosity will form conductive channels, which will seriously weaken the resistivity of the material and fail to meet the requirements of electrical safety regulations.

[0004] Therefore, there is an urgent need for a patrol trail system that can simultaneously ensure electrical safety and protect the environment. Utility Model Content

[0005] In order to solve the problems existing in the prior art, this utility model proposes a prefabricated eco-friendly high-resistance brick with mortise and tenon structure for patrol trails.

[0007] Preferably, the mortise and tenon structure consists of a tenon on one side of the brick and a groove on the opposite side of the brick that matches the tenon.

[0020] It should be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0021] The terms “comprising” and “including” indicate the presence of the described feature, whole, step, operation, element and / or component, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or collections thereof.

[0022] The term “and / or” refers to any combination of one or more of the associated listed items, as well as all possible combinations, and includes these combinations.

[0023] Example 1: See Figure 1 This embodiment proposes a prefabricated eco-friendly high-resistance brick with mortise and tenon structure for patrol trails, including a brick body, on both sides of which are provided with mortise and tenon structures that match the adjacent brick bodies; the brick body is composed of a three-layer composite structure, which from top to bottom includes: an eco-friendly concrete layer 1, a waterproof and insulating layer 2, and a high-resistance concrete layer 3.

[0024] In this embodiment, the high-resistivity concrete layer 3 is made of dense high-resistivity concrete composed of cement, carbide slag, quartz sand, kaolin and other raw materials, as well as admixtures to improve impermeability. Water is added and mixed according to a specific ratio, and the mixture is poured into a mold and vibrated to ensure that its volume resistivity is greater than 10000 Ω·m and its density is high. After curing, the thickness of the high-resistivity concrete layer 3 is controlled at 60-100mm. In actual laying, an independent grounding should be set. Preferably, the admixture for improving impermeability is a high-efficiency water-reducing agent, a densifying agent, or a water-increasing admixture, used to achieve high impermeability performance with an impermeability grade of P6 or above; It should be noted that the high-resistivity concrete layer 3 is the core safety layer of the brick body. In the event of a grounding fault, it can effectively suppress the step voltage and contact voltage on the ground surface, ensuring personnel safety.

[0025] In this embodiment, the waterproof insulation layer 2 is formed by applying a 3-5mm thick high-grade waterproof mortar, spraying polymer waterproof coating, or using waterproof roll material to all outer surfaces of the high-resistance concrete layer after curing, thus forming a dense isolation layer. It should be noted that the bonding strength between the waterproof insulation layer 2 on the upper surface of the high-resistivity concrete layer 3 and the upper and lower surfaces in contact with it should not be less than 0.5 MPa; As a preferred embodiment of this example, the bonding strength between the waterproof insulation layer 2 on the upper surface of the high-resistivity concrete layer 3 and the upper and lower surfaces in contact with it should not be less than 1.0 MPa. It should be noted that the waterproof insulation layer 2 is used to prevent moisture and electrolytes in the upper ecological concrete layer 1 from seeping down, ensuring that the electrical performance of the lower high-resistivity concrete layer 3 is not affected, and achieving physical isolation between electrical safety functions and ecological functions.

[0026] In this embodiment, the ecological concrete layer 1 is prepared using low-alkali cement, single-size aggregate, pore-forming agent and nutrient modifier. It is poured on the waterproof insulation layer 2 and vibrated to form the concrete. Its thickness is controlled at 150-200mm. The interior of the ecological concrete layer 1 is also filled with nutrient substrate required for plant growth. After curing, grass seeds can be pre-planted in its pores or sown after laying. In a preferred embodiment of this invention, the interconnected porosity is greater than 25%. As a preferred embodiment of this example, a continuous, highly insulating waterproof membrane is also provided on the side of the ecological concrete layer 1 to prevent current flowing down from the surface of the patrol trail from passing through the ecological concrete and directly entering the soil, causing the lower high-resistance layer to fail. It should be noted that the ecological concrete layer 1 is used to plant drought-resistant native plants to achieve greening of the walkway, rainwater infiltration, and cooling and humidification; furthermore, the ecological concrete layer 1 can be integrated with the high-resistance concrete layer 3 and the waterproof insulation layer 2 between the ecological concrete layer 1 to form a continuous waterproof and high-resistance measure.

[0027] See Figure 2 The brick body is divided into three sections: a left end section, a middle section, and a right end section. Each section has a different mortise and tenon structure, wherein: See Figure 2 -A, The left end plate has a groove and tenon that match the groove and tenon of the middle plate; See Figure 2 -B, The middle plate has grooves and tenons on both sides that match the grooves and tenons of the left end plate and the right end plate; See Figure 2 -C, The right end plate has a groove and tenon that match the groove and tenon of the middle plate; It should be noted that all bricks are prefabricated in the factory, and when the bricks are assembled, the joints of the mortise and tenon structure are sealed with a high-resistance sealant.
