Description

Technical Field

[0001] This invention relates to the field of building engineering and power facility safety technology, specifically to a dry and wet zone prefabricated ecological patrol trail system and its prefabrication and monitoring methods. Background Technology

[0002] Among existing patrol trail technologies, there exists a prefabricated, integrated solution that uses multiple layers of materials (such as an eco-friendly concrete layer, a waterproof layer, and a high-resistance concrete layer). This solution achieves a balance between ecology and safety to some extent, but its layered composite structure has the following inherent technical limitations: The inherent limitations of waterproofing: Relying on waterproof membranes or coatings to form an isolation layer, there is a risk of aging and failure at the bonding interface and joints with the concrete. Moisture (liquid and gaseous) may undergo uncontrollable lateral migration between layers, leading to the deterioration of high-resistance insulation performance after long-term service, thus failing to achieve intrinsic safety.

[0003] The mutual constraints of functional coupling: There is an inherent contradiction between the water conservation requirements of ecological functions and the long-term dryness requirements of trail structures; increasing structural strength often comes at the cost of increasing self-weight and material costs.

[0004] Lack of intelligent integration: Solid or layered structures lack a protected, dry, dedicated space, which means that sensors can only be externally mounted or shallowly buried, making them easy to damage and unable to monitor key mechanical parameters inside the structure, thus making it difficult to achieve true structural health monitoring.

[0005] Therefore, there is an urgent need in this field for a solution that can completely eliminate the aforementioned hidden dangers from the system architecture. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a dry-wet zoned prefabricated ecological patrol trail system and its prefabrication and monitoring methods to solve the aforementioned problems.

[0007] This invention provides the following technical solution: A prefabricated ecological patrol trail system with wet and dry zones includes a trail unit prefabricated from high-resistivity concrete. The cross-section of the trail unit adopts a three-dimensional functional spatial partitioning structure, including planting areas on both sides and a central walking area. The planting areas on both sides are wet areas, which are upward-opening trough-shaped structures used to accommodate planting soil and green plants. The central walking area is located between the planting areas on both sides. A structural equipment cavity is provided below the central walking area. The central walking area and the structural equipment cavity are dry areas. The structural equipment cavity is enclosed by the bottom panel of the central walking area, the bottom plate of the trail unit, and an integrally formed concrete shear wall connecting the two.

[0008] Furthermore, the concrete shear wall is arranged in a crisscrossing grid of beams.

[0009] Furthermore, the cavity of the structural equipment is pre-set with guide rails or slots for installing IoT monitoring modules, as well as wire holes for wiring.

[0010] Furthermore, an inspection port is provided on the panel of the central walking area, with a socket-type cover plate flush with the central walking surface inside, and sealed with elastic sealant.

[0011] Furthermore, adjacent walkway units are connected by interlocking grooves at the joints in the central walking area, and high-performance elastic sealant is used to fill the joints in the planting areas on both sides.

[0012] Furthermore, the bottom of the planting areas on both sides is provided with a sloped gravel drainage layer, and water is drained out through pre-buried drainage pipes.

[0013] The present invention also discloses a prefabrication method for the system described in any of the foregoing claims, comprising the following steps: S1: Binding an integrated steel mesh, the steel mesh covering the walking area panel, the walkway unit floor slab, and the concrete shear wall area connecting the two; S2: Place an inner mold in the mold to form the cavity of the structural device; S3: Pour high-resistance concrete and use vibration technology to ensure that the concrete filling in the concrete shear wall area is dense and free of defects; S4: After curing and reaching the required strength, demold to obtain a rough walkway unit with a structural equipment cavity and planting areas on both sides; S5: Lay a gravel drainage layer and a geotextile filter layer in sequence within the planting area.

[0014] The present invention also discloses a structural health monitoring method based on any of the foregoing systems, comprising the following steps: P1: Install mechanical sensors at key stress points inside the cavity of the structural equipment; P2: Collect internal stress, strain, or vibration data of the walkway under load; P3: Transmit the collected data to the data processing center; P4: Compare the processed data with the preset safety threshold to assess the structural health status and issue an alert when an anomaly occurs.

[0015] Furthermore, the mechanical sensor includes a MEMS tilt sensor and a temperature and humidity sensor.

[0016] Furthermore, the collected data is transmitted to a cloud platform for analysis via a solar-powered LoRa gateway.

[0017] The present invention has the following beneficial technical effects: This invention is a "container" or "frame" constructed of high-resistivity concrete. It completely separates the load-bearing structure (the frame itself) from the ecological function (internal soil filling and planting) in space, representing a fundamental structural difference from existing technologies. This invention actively guides water away from the walking surface, fundamentally cutting off the dangerous leakage current path.

[0018] This invention achieves inherent electrical safety: by using a one-piece molded concrete shear wall as a permanent isolation barrier, it completely eliminates the possibility of moisture migrating from wet areas to dry areas through physical means. Its safety mechanism does not rely on easily aging flexible materials, but rather on the permanence and density of the concrete structure, achieving a fundamental shift from "prevention" to "complete elimination."

[0019] This invention overcomes the bottleneck of functional coupling: by decoupling load-bearing, ecological, and equipment functions through a three-dimensional spatial layout, each functional module can be optimized independently. The central beam-grid cavity structure significantly reduces its self-weight while ensuring and even improving structural stiffness and load-bearing capacity through an efficient force-bearing system.

[0020] This invention creates a built-in intelligent platform: the device cavity provides a dedicated space that is mechanically coupled with the main structure and protected by the entire environment, making it possible to monitor key mechanical parameters inside the structure in a long-term, stable and accurate manner, laying a solid foundation for predictive maintenance.

[0021] This invention improves prefabrication and economy: it provides a prefabrication method for components with complex cavities, enabling efficient factory production of multifunctional integrated components and significantly reducing the overall cost throughout the entire life cycle.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1 like Figure 1 and Figure 2 As shown, this invention discloses a dry-wet zoned prefabricated ecological patrol trail system. The system includes a trail unit 1, integrally prefabricated from high-resistivity concrete. The core of the trail unit 1 lies in the division of its internal space by concrete shear walls 5, including planting areas 3 on both sides and a central walking area 2. A structural equipment cavity 4 is formed in the middle by the bottom panel of the walking area 2, the trail unit base plate 6, and the integrally formed concrete shear walls 5 connecting the two. The concrete shear walls 5 are arranged in a crisscrossing beam grid pattern.

[0026] In this embodiment, planting area 3 is designated as a "wet area," which is an upward-opening trough-shaped structure. Its interior is sequentially filled with a gravel drainage layer 7, a geotextile filter layer 8, and planting soil 9, and planted with greenery 10. Infiltrating water is collected by the gravel drainage layer 7 and discharged along the slope into the drainage pipe 11. Walking area 2 and the structural equipment cavity 4 beneath it constitute a "dry area."

[0027] Various smart devices can be installed within the structural equipment cavity 4. In this embodiment, the structural equipment cavity 4 is pre-set with guide rails or slots for installing IoT monitoring modules, as well as wiring holes. An inspection port 14 is located on the walking area 2, sealed with a socket-type cover plate 15 and further sealed with elastic sealant 13, facilitating maintenance of the equipment within the structural equipment cavity 4.

[0028] like Figure 3As shown, during on-site installation, multiple walkway units 1 are connected by a grooved connection structure 12 in the walking area to achieve load transfer and positioning, ensuring a flat walking surface. The joint filling material is of two types: a layer of crushed stone at the bottom and silicone sealant on top, with asphalt-impregnated hemp fibers inside. The joints of the planting area 3 are filled with high-performance elastic sealant 13 to ensure water tightness and planting continuity.

[0029] Example 2 This invention also discloses a prefabrication method for a dry-wet zoned prefabricated ecological patrol trail system, comprising the following steps: During prefabrication, an integral steel mesh is first tied, covering the walkway panel 2, the walkway unit base slab 6, and the concrete shear wall 5 connecting the two. Then, an inner mold (such as a removable steel inner mold or a retained foam inner mold) is placed inside to form the structural equipment cavity 4. High-resistivity concrete is then poured and carefully vibrated to ensure the concrete shear wall 5 is compacted. After curing and demolding, the main structure is obtained, followed by the laying of a gravel drainage layer 7 and a geotextile filter layer 8. Planting soil 9 and green plants 10 are added after delivery to the site to reduce the weight of the prefabricated components during transport.

[0030] Example 3 This invention also discloses a structural health monitoring method based on a dry-wet zoned prefabricated ecological patrol trail system, comprising the following steps: like Figure 2 As shown, sensors, including a MEMS tilt sensor 16 and a temperature and humidity sensor 17, are installed inside the structural equipment cavity 4 of the installed walkway system. After data acquisition, the data is transmitted to the cloud platform 19 for analysis via a solar-powered LoRa gateway 18. When the detected stress value exceeds a preset threshold, the system automatically sends an alert to the mobile device 20 of the maintenance personnel, realizing intelligent management of structural safety.

[0031] This system and method are particularly suitable for the construction of inspection channels with stringent requirements for electrical safety and intelligent management, providing a comprehensive solution that is safe, ecological, intelligent, and economical.

[0032] The embodiments described above are merely illustrative of specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
