Description

Technical Field

[0001] This utility model belongs to the field of slope protection technology, and more specifically, relates to a lightweight ecological slope protection system with flame-retardant properties. Background Technology

[0002] With the continuous expansion of my country's high-grade highway network and the ongoing construction of mountain roads, the stability and ecological protection of soil slopes have become increasingly prominent issues. In the field of road engineering, the stability of soil slopes is crucial to the safe use of roads and the safety of the surrounding environment. Currently, scaffolded slope protection, as a type of local slope protection structure, is widely used in various road construction projects. It involves constructing a framework of materials such as concrete or masonry on the slope surface and then adding soil and greenery within the framework to achieve the purpose of slope protection. The design of a framework-based slope protection system aims to enhance slope stability and reduce the risk of soil displacement by utilizing the structural strength of the framework. Simultaneously, through soil mounding and greening within the framework, the root systems of the vegetation stabilize the soil, and the vegetation intercepts and disperses rainwater, further reducing the likelihood of slope damage from natural factors such as rainwater erosion. This protection method, to a certain extent, considers the combination of engineering protection and ecological greening, offering certain ecological and landscape advantages compared to purely engineering protection structures. However, in long-term practical application, the skeleton slope protection has revealed many shortcomings, such as: due to the relatively loose soil in the backfill area and the low vegetation coverage, it is impossible to form an effective vegetation cover layer to resist rainwater erosion, often resulting in problems such as rainwater erosion and localized scouring, leading to soil loss on the slope and affecting slope stability; secondly, the skeleton is a rigid structure, and when uneven settlement occurs on the slope, the skeleton is easily affected by stress concentration. Coupled with rainwater erosion or various external special loads, it is very easy to cause localized erosion, skeleton voiding and damage, and rockfall, which seriously weakens the protective capacity of the skeleton slope protection; thirdly, the construction of skeleton slope protection requires multiple steps such as skeleton pouring or masonry, backfilling, and vegetation planting, and each step affects the others, resulting in slow construction speed, especially during winter and rainy seasons; in addition, the fire resistance of skeleton slopes is poor, and the high construction cost, high maintenance frequency, and limited protective effect lead to high potential repair costs, resulting in low overall economic benefits of skeleton slope protection.

Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] Please refer to Figures 1 to 4 This utility model provides a lightweight ecological slope protection system with flame-retardant properties, comprising: a soil amendment layer 2, a composite fiber water-retaining layer 3, a flame-retardant component 4, and a drainage interception component 5; the soil amendment layer 2 is disposed on the slope surface of the slope 1; the composite fiber water-retaining layer 3 is disposed on the upper end of the soil amendment layer 2; the flame-retardant component 4 comprises: a reinforcing mesh 41, polymer mesh wire 42, and an anchor rod 43; the polymer mesh wire 42 is laid on the upper end of the composite fiber water-retaining layer 3; the reinforcing mesh 41 is embedded in the polymer mesh wire 42; one end of the anchor rod 43 penetrates sequentially. The polymer mesh 42, the composite fiber water-retaining layer 3, and the soil improvement layer 2 are anchored inside the slope 1. The reinforcing mesh 41 is fixedly connected to the exposed portions of multiple anchor rods 43 by binding steel wires. The drainage component 5 includes: a water-retaining edge 51, a first drainage ditch 52, and a second drainage ditch 53. The first drainage ditch 52 is fixedly installed at the top edge of the slope 1. The second drainage ditch 53 is fixedly installed at the toe of the slope 1. Several water-retaining edges 51 are respectively installed on the upper ends of the walls of the first drainage ditch 52 and the second drainage ditch 53.

[0023] Understandably, by setting a soil amendment layer 2 at the upper end of slope 1, the water-holding capacity of the slope and the quality of the plant growth substrate can be effectively improved, providing a good foundation for the rapid establishment of vegetation. Furthermore, the composite fiber water-retaining layer 3 set on the upper end of the soil amendment layer 2 can further enhance the water storage and slow release function, reduce irrigation needs, and improve the survival rate of vegetation under drought conditions. Secondly, by setting polymer mesh 42 on the composite fiber water-retaining layer 3, its high temperature resistance and flame retardant properties can be utilized to achieve both soil stabilization and flame retardant functions, and effectively suppress the spread of fire. Furthermore, by having one end of the anchor rod 43 penetrate through multiple structural layers and extend into the interior of slope 1, a deep anchoring and overall reinforcement synergistic effect is formed, significantly improving the shear strength and deformation adaptability of the slope protection structure, and effectively preventing slippage and damage caused by uneven settlement or rainwater infiltration. In addition, the interception and drainage components 5 can effectively intercept and orderly drain water from the slope, avoiding local erosion caused by concentrated rainwater scouring.

[0024] Specifically, the soil amendment layer 2 includes: renewable heat-processed bark and wood fiber, biochar, cross-linked polysaccharide biopolymer, and fast-acting and slow-release soil building components; wherein: after heat processing, the bark and wood fiber have a large porous structure, which can increase the soil's aeration and permeability, while also retaining a certain amount of moisture, providing a good growth environment for plant roots; biochar has high porosity and a large specific surface area, which can adsorb nutrients and water in the soil, reducing nutrient loss; cross-linked polysaccharide biopolymer can form a network structure between soil particles, agglomerating the soil particles together and improving soil cohesion and stability; the fast-acting and slow-release soil building components include soil, inorganic fertilizers, and organic fertilizers, thereby providing stable support and enabling plants to maintain upright growth, while also providing immediate and long-term nutrient support for plant growth.

[0025] The composite fiber water-retaining layer 3 comprises: fine thermotropic wood fibers, interlocking synthetic fibers, a polymer water-retaining matrix, microporous particles, and a growth promoter; wherein: the fine thermotropic wood fibers, having undergone fine thermotropic treatment, possess a rich porous structure, increasing the product's air permeability and water retention, while also providing a certain degree of flexibility and natural texture. During decomposition, they slowly release organic nutrients, which is beneficial for soil microbial activity and plant growth; the interlocking synthetic fibers are made from high-strength synthetic fibers, which interweave to form an interlocking structure, enhancing the overall strength and stability of the structural layer and preventing rainwater erosion; the polymer water-retaining matrix has strong water absorption and retention capabilities, and can withstand water erosion... The composite fiber absorbs hundreds of times its own weight in water and releases it slowly during droughts, providing a continuous water supply for plant growth while reducing evaporation and seepage. The microporous particles further improve the product's aeration, allowing better air circulation within the product, which is beneficial for plant root respiration. Simultaneously, the microporous structure can adsorb and store nutrients, improving nutrient utilization. Growth promoters can be selected based on plant species and slope environment, such as preparations containing plant hormones (e.g., auxins, cytokinins), trace elements (e.g., iron, zinc, manganese), or beneficial microorganisms (e.g., rhizobia, Bacillus), which can stimulate plant growth, enhance plant resistance, promote root development, and improve nutrient absorption efficiency. It should be noted that the composite fiber water-retaining layer 3 also includes plant seeds suitable for the slope environment.

[0026] In an optional embodiment, the first drainage ditch 52 has a V-shaped cross-section and the second drainage ditch 53 has a rectangular cross-section, in order to optimize the graded drainage efficiency of the slope water system, enhance the overall drainage reliability, and reduce erosion of the slope greening.

[0027] In an optional embodiment, the ecological slope protection system has multiple steps 6 extending longitudinally along the slope at intervals of 100m along the slope surface. These steps provide a safe passage for subsequent slope vegetation maintenance and facility repair, improving the convenience of operation and maintenance. They can also divide the excessively long flow path on the slope, playing a role in longitudinal water diversion and erosion prevention, further enhancing the protection effect.

[0028] In an optional embodiment, multiple pieces of the reinforcing mesh 41 are connected by twisting steel wires (not shown in the figure) to form a continuous and integral reinforcing structure, which effectively transfers and disperses the slope load, enhances the overall stability and deformation resistance of the slope protection system, prevents the expansion of local damage, and improves the collaborative performance of the structure.

[0029] In an optional embodiment, the anchor rods 43 are arranged in a quincunx pattern on the slope, and the spacing between adjacent anchor rods 43 is 1m, in order to improve the anchoring density and spatial coverage uniformity, thereby significantly improving the restraint effect on the slope soil and enhancing the anti-sliding and anti-pull-out performance, especially suitable for loose or easily deformable soil slopes.

[0030] In an optional embodiment, the polymer mesh 42 is a sheet-like mat, which is composed of flame-retardant mesh fibers randomly interwoven and wound together, made of a blend of polypropylene polymer and flame retardant, and the porosity of the sheet-like mat is not less than 90%. It should be noted that the flame retardant is a commonly used flame-retardant material in the prior art, such as phosphorus-based flame retardants and nitrogen-based flame retardants. In other embodiments, other types of flame-retardant materials may also be used, which are not specifically limited here.

[0031] Please refer to Figures 1 to 4 Furthermore, the flame-retardant component 4 also includes: a temperature sensor 44, a water storage tank 45, a water pump 46, a spray head 47, and a control module 48; multiple temperature sensors 44 are evenly distributed on the upper end of the polymer mesh 42; the water storage tank 45 is buried below the second drainage ditch 53 and is connected to the outside through a water inlet pipe 451 passing through the bottom of the ditch; the water inlet of the water pump 46 is connected to the water storage tank 45, and the water pump 46 corresponds one-to-one with the water storage tank 45; multiple spray heads 47 are evenly distributed on the upper end of the polymer mesh 42 and are connected to the outlet of the adjacent water pump 46 through a water supply pipe; the control module 48 is located on one side of the water pump 46, and is communicatively connected to several adjacent temperature sensors 44 and electrically connected to the water pump 46. The control module 48 is configured to receive signals from the temperature sensors 44 and control the water pump 46 to start and stop. Understandably, through the above design, when the temperature sensor 44 detects an abnormal temperature rise, it immediately triggers an early warning signal and sends it to the control module 48. The control module 48 then starts the nearby water pump 46 and uses the spray head 47 to precisely spray and cool the high-temperature area, effectively curbing the spread of fire. When the temperature returns to normal, the water pump 46 is turned off to avoid waste.

[0032] In an optional embodiment, multiple water storage tanks 45 are set at 100m lateral intervals along the slope to improve the reliability of water storage and supply, reduce the risk of single-point failure, facilitate zoned control and maintenance, and, in combination with the terrain, make reasonable layout to facilitate the collection and utilization of natural precipitation, enhance the system's autonomous water supply capacity, and improve overall operating efficiency and fire response speed.

[0033] In an optional embodiment, the water supply pipe includes a main water supply pipe connected to the outlet of the water pump 46, and several branch water supply pipes connected to the main water supply pipe. Each branch water supply pipe corresponds to one of the sprinkler heads 47, and each branch water supply pipe is equipped with a solenoid valve. This solenoid valve is electrically connected to the control module 48 on the corresponding side of the water pump 46. The control module 48 is configured to receive signals from the temperature sensor 44 and control the opening and closing of the corresponding solenoid valve. It is understood that through the above design, when a local temperature anomaly is detected, the control module 48 can automatically activate the water pump 46 and the corresponding area solenoid valve, and promptly close the water pump 46 and the corresponding area solenoid valve when the temperature returns to normal, achieving directional sprinkler fire suppression, avoiding full-area activation, saving water resources, improving response efficiency, and enhancing system intelligence and operational reliability.

[0034] It should be noted that, in some cases, the control module 48 includes a signal receiving submodule, a processor, and a relay. The signal receiving submodule includes a signal processing circuit (e.g., amplification and filtering) and an analog-to-digital converter (ADC), which is used to receive and amplify the alarm signal from the temperature sensor 44. The processor includes a programmable logic controller (PLC) with an algorithm that can perform logical operations. It is used to receive the conditioned sensor signal and issue control commands to control the start or stop of the water pump and the opening or closing of the solenoid valve. The relay includes an electromagnetic relay, which is used to convert the control signal from the processor into a high-current signal that can drive the water pump motor. By controlling a high current with a small current, the control of the water pump 46 and the solenoid valve can be achieved.

[0035] In an optional embodiment, the inlet height of the water inlet pipe 451 is 2cm to 4cm higher than the bottom surface of the second drainage ditch 53, and a hemispherical filter screen 452 is detachably provided at the inlet to effectively prevent mud and debris from the bottom of the ditch from directly entering the pipe and avoiding blockage. At the same time, the detachable hemispherical filter screen 452 can not only intercept suspended impurities and ensure clean water, but also facilitate regular disassembly, cleaning or replacement, making maintenance simple.

[0036] In an optional embodiment, the flame-retardant component 4 further includes a charging module 49, which comprises a solar panel 491 and a battery compartment 492. The solar panel 491 is mounted above the wall of the second drainage ditch 53 via a support rod. The battery compartment 492 contains a storage battery electrically connected to the solar panel 491. The charging module 49 corresponds one-to-one with the control module 48, and the storage battery in the battery compartment 492 is electrically connected to the corresponding control module 48 and several temperature sensors 44 adjacent to the control module 48. It is understood that the design of the solar panel 491 and battery compartment 492 fully utilizes clean energy, eliminating dependence on the external power grid and improving the applicability and operational reliability of the ecological slope protection system in remote or grid-free areas. Simultaneously, the modular layout of the power supply system facilitates maintenance and expansion, ensuring the continuous and stable operation of key components such as the temperature sensor 44, water pump 46, sprinkler head 47, and control module 48, significantly enhancing the intelligent monitoring and active fire prevention capabilities of this slope protection system under all-weather conditions.

[0037] The working principle of this utility model is as follows: After leveling the slope 1, a soil improvement layer 2, a composite fiber water-retaining layer 3, and a flame-retardant component 4 are sequentially installed on the slope surface from bottom to top, forming a multi-layered synergistic protection system. The soil improvement layer 2 improves the planting substrate on the slope, and the composite fiber water-retaining layer 3 enhances water retention capacity, providing a favorable environment for vegetation growth. Simultaneously, a reinforcing mesh 41 is embedded within polymer mesh 42 and laid flat on top of the composite fiber water-retaining layer 3 from top to bottom. Then, anchor rods 43 are passed through these structural layers and anchored deep into the slope, and connected to the reinforcing mesh 41 wires with steel wires, achieving overall slope reinforcement and stabilization. Finally, a first drainage ditch 52 is placed at the top of the slope, and a second drainage ditch 53 is placed at the bottom of the slope, working in conjunction with a water-retaining edge 51 to effectively intercept and drain surface water, preventing... The system prevents erosion of the slope's structural layers. Furthermore, when ambient temperature rises or combustion occurs due to other reasons, temperature sensors 44 distributed on the polymer mesh 42 detect abnormal signals, triggering the control module 48 to activate the corresponding area's water pump 46 and the solenoid valve on the water supply branch pipe. The water pump 46 draws water from the corresponding water storage tank 45 and delivers it through the water supply pipe to the sprinkler heads 47 within the area of ​​the corresponding temperature sensor 44 for spray cooling. Simultaneously, the water storage tank 45 collects rainwater from the second drainage ditch 53 through the inlet pipe 451, which is equipped with a hemispherical filter screen 452 to prevent clogging. Additionally, solar panels 491 are installed above the wall of the second drainage ditch 53, converting solar energy into electrical energy, which is stored in the battery compartment 492 to power the water pump 46, solenoid valves, and sensors, achieving energy self-sufficiency. The entire ecological slope protection system integrates ecological protection, structural reinforcement, intelligent monitoring, active fire prevention, and energy-saving water supply, achieving long-term slope stability and safe operation.
