Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, and in particular to an ecological slope protection system integrating adaptive drainage and reinforcement for water conservancy projects. Background Art

[0002] Ecological slope protection, a structural system that combines soil and water conservation with vegetation restoration, has been increasingly used in water conservancy projects in recent years. It typically involves establishing ecological troughs on the slope surface, filling them with substrate, and planting herbaceous root plants to achieve slope reinforcement and reduce surface runoff, gradually replacing traditional rigid slope protection structures. However, under special hydrological conditions such as floods, flood discharges, or sustained heavy rainfall, existing ecological slope protection systems still face numerous technical bottlenecks. For example, under strong water flow, the stems and leaves of slope vegetation are prone to swaying, which in turn affects the roots and causes them to become detached from the soil, affecting overall stability. Most ecological slope protection structures lack rapid response and active protection mechanisms, making them unable to provide effective protection in time when sudden water level changes occur, which can easily cause concentrated scouring and damage to the soil structure. Furthermore, existing protective nets are mostly deployed by traction in a single direction, which can easily cause shear or friction damage to the vegetation during the covering process, undermining its ecological restoration effect.

[0003] This experimental team has been browsing and researching a large amount of relevant records and materials on the relevant technologies of ecological slope protection for a long time. At the same time, relying on relevant resources and conducting a large number of relevant experiments, after a large number of searches, it was found that there are existing technologies such as CN108239961B, CN111809565B, CN118872549B and CN118029328B disclosed in the prior art. For example, a water conservancy project river channel ecological slope protection structure disclosed in the prior art relates to the field of water conservancy engineering technology, including a plurality of collecting plates arranged on one side of the slope, the middle part of the collecting plate is rotatably connected to the slope, and the lower surface of the collecting plate is provided with a V-shaped surface that can fit with the slope when the collecting plate rotates; the V-shaped surface includes an upper plane and a lower plane, when the upper plane and the slope are in contact, the collecting plate and the slope form a diversion surface for water flow, and when the lower plane and the slope are in contact, the collecting plate and the slope form a collection cavity that can intercept water and soil, and the lower plane is provided with a filter hole for water to pass through. However, there are still obvious deficiencies in dealing with overall slope erosion and rapid closure protection, including a lack of ability to coordinate release, tighten protective nets and precisely anchor.

[0004] The present invention is made in order to solve the common problems in the field such as delayed response, incomplete protection, easy damage to vegetation, unstable structure and easy soil loss of ecological slope protection systems. Summary of the Invention

[0005] The purpose of the present invention is to address the deficiencies in the current field and to propose an ecological slope protection system for water conservancy projects that integrates adaptive drainage and reinforcement.

[0006] In order to overcome the deficiencies of the prior art, the present invention adopts the following technical solutions:

[0007] An ecological slope protection system integrating adaptive drainage and reinforcement for water conservancy projects, the ecological slope protection system comprising a plurality of ecological troughs cast on the slope surface of a slope body by concrete, water diversion channels arranged on both sides of the slope surface, a base laid at the bottom of the ecological troughs, root plants planted in the base, a storage module arranged at the bottom of the slope body, a protective net stored in the storage module, a control room arranged at the top of the slope body, and a stabilization module for controlling the protective net to cover and stabilize the ecological troughs of the slope body, wherein the control room is provided with at least four windows communicating with the outside world, and the control room is fixed to the top of the slope through a support unit.

[0008] Furthermore, the storage module includes an open groove pre-buried in the bottom of the slope body, a closing cover capable of closing the opening of the open groove, at least two traction rings fixedly connected to both sides of the closing cover, at least two fixing rings fixedly connected to both sides of the closing cover, a rotating rod on both sides of the open groove that is rotatably engaged with the axis through a bearing seat, and a accommodating area for accommodating a motor provided on one side of the open groove;

[0009] When the closing cover is removed from above the opening slot, the operator can place the motor in the accommodating area and use a coupling to coaxially connect and fix the motor output shaft and the rotating rod. The motor drives the rotating rod to rotate, thereby winding the protective net outside the opening slot back into the opening slot.

[0010] Furthermore, the protective net includes a net body woven by flexible ropes and several fixing rods horizontally fixed on the net body, and the top of the net body is connected and fixed to the bottom of the closing cover, and the bottom of the net body is connected and fixed to the rotating rod. The longitudinal section of the flexible rope is from the inside to the outside: galvanized steel wire rope and a foamed polyethylene sheath formed by an extrusion coating process.

[0011] Furthermore, the horizontal edge of the top of the protective net is the upper edge of the protective net, and the horizontal edge of the bottom is the lower edge of the protective net. A plurality of fixed sleeves are sequentially sleeved on the net opening near the upper edge. The fixed sleeves are stainless steel round tubes, and the side wall of the fixed sleeve is provided with a longitudinal slit along the axis of the tube.

[0012] The upper end of the protective net is firmly connected to the bottom of the closing cover through a fixed sleeve. Each fixed sleeve is mounted on the corresponding mesh position along the net edge, and the longitudinal slit of each fixed sleeve is aligned with the embedded steel plate at the bottom of the closing cover. Subsequently, the longitudinal slit edge of the fixed sleeve and the embedded steel plate are spot-welded and fixed, and then high-strength bolts are used to penetrate the fixed sleeve and the embedded steel plate and lock them, thereby finally achieving a rigid connection between the top of the protective net and the bottom of the closing cover.

[0013] Furthermore, a plurality of through holes perpendicular to the axis of the rotating rod are equidistantly opened on the outer wall of the rotating rod, and the lower net is wrapped around the outer wall of the rotating rod at least twice to form a winding layer, and then an integrated arc-shaped locking piece matching the outer diameter of the rotating rod is attached to the outside of the winding layer, and the locking piece is aligned with the through hole on the rotating rod, and then the fastening bolts are passed through the locking piece, the winding layer and the rotating rod in sequence and locked, so as to achieve rigid fixation of the bottom of the protective net and the rotating rod.

[0014] Furthermore, the stabilization module includes two first steel cables, two second steel cables, two support columns, two support piers, two first hoisting devices, two second hoisting devices and four rope guide assemblies;

[0015] Among them, one end of each first steel cable is connected to the traction ring through a locking piece, and the other end of the first steel cable is wound around the corresponding first winch device after passing through the control room window; one end of each second steel cable is connected to the fixing ring through a locking piece, and the other end of the second steel cable is wound around the corresponding second winch device after passing through the control room window; two first winch devices are arranged in the control room for winding and releasing the first steel cables; two second winch devices are arranged in the control room for winding and releasing the second steel cables; two support columns are vertically installed on both sides of the bottom of the slope body; two support piers are respectively arranged on both sides of the top of the slope body; four rope guide assemblies are respectively installed on the top of the support columns and the support piers, for guiding the first steel cable or the second steel cable to wind out smoothly.

[0016] Furthermore, the rope guide assembly includes a U-shaped bracket mounted on the top of the support column or the support pier, a first guide wheel rotatably fitted in the opening area of ​​the U-shaped bracket, and a second guide wheel rotatably fitted in the opening area of ​​the U-shaped bracket, wherein the second guide wheel is arranged below the first guide wheel;

[0017] The U-shaped bracket is made of high-strength alloy steel, and the bottom of the U-shaped bracket is fixed to the reinforcing steel plate anchor pre-arranged on the top of the support column by welding and bolts.

[0018] Furthermore, one end of the first steel cable is fixedly connected to the traction ring on the closing cover, and then passes through the rope guide assembly on the top of the supporting pier, first passes through the bottom of the second guide wheel, then goes upward from the second guide wheel around its wheel rim, and is led out from the gap between the first guide wheel and the second guide wheel, and finally enters the control room through the window and is wound around the corresponding first winch device;

[0019] One end of the second steel cable is fixedly connected to the fixed ring, and then passes through the rope guide assembly arranged on the top of the support column, is led out through the gap between the first guide wheel and the second guide wheel, and finally enters the control room through the window and is wound around the corresponding second winch device.

[0020] Furthermore, the slope surface is provided with an inwardly recessed accommodating groove near the top of the slope. The shape and size of the accommodating groove match the base of the closing cover and is used to accommodate the closing cover. The second steel cable drives the closing cover to move upward along the slope surface and stops the closing cover in the accommodating groove.

[0021] Furthermore, before a flood warning or flood discharge operation is initiated, to prevent the slope from being eroded and soil loss, the first and second hoisting devices in the control room are linked to drive the protective net to unfold and cover the slope. The specific operation process is as follows:

[0022] S101: The first hoisting device in the control room is activated, pulling and reeling in the first steel cable connected to the bottom of the closing cover. As the first steel cable is gradually reeled in, the closing cover rises vertically from the bottom of the slope until it is aligned with the highest point of the ecological tank. During this process, the protective net connected to the bottom of the closing cover is pulled out of the open tank section by section and unfolds downward under the action of gravity.

[0023] S102: The second hoisting device in the control room is activated to drive the second traction cable connected to the closing cover to reel in. Simultaneously, the first hoisting device is activated to gradually release the first traction cable. The closing cover, pulled by the second cable, moves approximately horizontally toward the top of the slope. The movement path of the closing cover is constrained and guided by the rope guide assembly on the top of the supporting pier. Ultimately, the closing cover is positioned and fixed in a pre-set receiving groove at the top of the slope.

[0024] S103: After the closed cover of the protective net is embedded in the groove at the top of the slope, the protective net maintains an overall tensioned covering state from the top to the bottom of the slope, effectively shielding the slope and reducing the intensity of water scouring. At the same time, it has the dual functions of protecting root plants and reinforcing the slope structure.

[0025] The beneficial effects achieved by the present invention are:

[0026] 1. Automatic deployment and tensioning of the protective net: Through the coordinated traction of the first and second steel cables, combined with the movement of the closing cover and the engagement of the accommodating groove, the protective net can be automatically deployed from the bottom of the slope to the top and tensioned and fixed, improving the system's rapid response capabilities in extreme working conditions such as floods.

[0027] 2. Enhance the dual protection capabilities of slope ecology and structure: After being deployed, the protective net can effectively limit the swing of vegetation stems and leaves, slow down the intensity of water scouring, inhibit soil loss, protect ecological vegetation while enhancing slope stability, and significantly improve the comprehensive performance of the ecological slope protection system.

[0028] 3. Improve system adaptability and service life: The protective net can be rolled up in the storage module to avoid long-term exposure and aging. The stable closure of the closing cover, combined with the rope guide assembly and winch device, realizes the integrated integration of equipment and structure, which is conducive to maintenance, expansion and reuse.

[0029] 4. Optimize the laying method of the protective net to reduce damage to vegetation: Avoid the shear or friction damage to vegetation caused by the traditional method of covering the slope surface by pulling the sliding protective net in a single direction. The present invention uses double steel cable traction and vertical release followed by horizontal expansion path control to significantly improve the response speed, service life and ecological adaptability of the ecological slope protection system in complex hydraulic environments.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with its embodiments; it should be pointed out that the specific embodiments described herein are only used to explain the present invention and are not used to limit this case. For those skilled in the art, after reviewing the following detailed description, other systems, methods and / or features of this embodiment will become apparent. In addition, the terms describing the positional relationship in the accompanying drawings are only for illustrative purposes and cannot be understood as limiting this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to the specific circumstances.

[0040] Example 1: Combined with the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 , Attachment Figure 6 and attached Figure 7 This embodiment constructs an ecological slope protection system that integrates adaptive drainage and reinforcement for water conservancy projects. The ecological slope protection system includes several ecological troughs cast on the slope surface of the slope body by concrete, water diversion channels arranged on both sides of the slope surface, a base laid at the bottom of the ecological troughs, root plants planted in the base, a storage module arranged at the bottom of the slope body, a protective net stored in the storage module, a control room arranged at the top of the slope body, and a stabilization module for controlling the protective net to cover and stabilize the ecological troughs of the slope body.

[0041] The base is composed of loam, lightweight expanded clay, coconut fiber, bentonite, biochar, controlled-release compound fertilizer and super absorbent resin. The root plants include bermudagrass, bahia grass, vetiver, peanut grass, dwarf paspalum and other deep-rooted and sparsely leafed grass species to reduce water flow resistance and improve soil consolidation and slope stabilization effects when floods occur.

[0042] The storage module includes an open groove pre-buried in the bottom of the slope body, a closing cover that can close the opening of the open groove, at least two traction rings fixedly connected to both sides of the closing cover, at least two fixing rings fixedly connected to both sides of the closing cover, a rotating rod on both sides that is able to rotate axially in the open groove through bearing seats, and a accommodating area for accommodating a motor arranged on one side of the open groove.

[0043] When the closing cover is removed from above the opening slot, the operator can place the motor in the accommodation area and use a coupling to coaxially connect the motor output shaft with the rotating rod. The motor drives the rotating rod to rotate, thereby winding the protective net outside the opening slot back into the opening slot.

[0044] The opening edge of the opening groove is provided with a snap-fit ​​groove, and the outer periphery of the closing cover is provided with a flange structure that cooperates with the snap-fit ​​groove. The flange is embedded in the snap-fit ​​groove to achieve snap-fit, thereby achieving a stable closure of the opening groove by the closing cover.

[0045] The closing cover is integrally cast from steel fiber reinforced concrete. During the casting process, a number of embedded steel plates are simultaneously embedded in the bottom of the closing cover, and a number of embedded anchors are simultaneously embedded in the top of the closing cover for subsequent structural connection and fixation. The traction ring and the fixing ring are made of high-strength low-alloy steel or titanium alloy. The traction ring and the fixing ring are respectively welded to the embedded anchors in the closing cover or fixed with bolts to be firmly mounted on the upper surface of the closing cover.

[0046] The protective net includes a net body woven by flexible ropes and a plurality of fixing rods horizontally fixed to the net body. The top of the net body is connected and fixed to the bottom of the closing cover, and the bottom of the net body is connected and fixed to the rotating rod. The longitudinal section of the flexible rope is composed of galvanized steel wire rope and a foamed polyethylene sheath formed by an extrusion coating process from the inside to the outside.

[0047] The edge area of ​​the net body is reinforced by repeatedly weaving at least two flexible ropes. The reinforcement belt is used to enhance the tensile strength and wear resistance of the edge. The fixing rod is made of solid stainless steel flat bar, and the protective net is designed as follows: when the stabilization module pulls the protective net to cover the slope surface of the slope body, the fixing rod of the protective net abuts against the edge of the ecological trough without touching or squeezing the root plants in the ecological trough, ensuring that the root plants in the ecological trough are not squeezed and disturbed by the fixing rod during the unfolding of the protective net. At the same time, the arrangement of the fixing rod can enable the protective net to maintain continuous tension and avoid entanglement during the winding and unfolding process.

[0048] Specifically, adjacent fixed rods are arranged at a spacing of n×L, where L is the center distance of the slots of adjacent ecological slots along the slope direction, the value of n ranges from 1 to N, N is the total number of ecological slots arranged in sequence along the slope direction, and the specific value of n is determined by technical personnel in this field according to actual needs and working conditions, and is not limited here.

[0049] The horizontal edge of the top of the protective net is the upper edge of the protective net, and the horizontal edge of the bottom is the lower edge of the protective net. A number of fixed sleeves are sequentially sleeved on the net opening near the upper edge. The fixed sleeves are stainless steel round tubes, and a longitudinal slit is provided on the side wall of the fixed sleeve along the axis of the tube.

[0050] The upper end of the protective net is firmly connected to the bottom of the closing cover through a fixed sleeve. Specifically, each fixed sleeve is sleeved on the mesh position corresponding to the upper edge of the net, and the longitudinal slit of each fixed sleeve is aligned with the embedded steel plate at the bottom of the closing cover. Subsequently, the longitudinal slit edge of the fixed sleeve and the embedded steel plate are spot-welded and fixed, and then high-strength bolts are used to penetrate the fixed sleeve and the embedded steel plate and lock them, finally achieving a rigid connection between the top of the protective net and the bottom of the closing cover.

[0051] The outer wall of the rotating rod is equidistantly provided with a plurality of through holes perpendicular to the axis of the rotating rod. The lower net is wound around the outer wall of the rotating rod at least twice to form a winding layer. Then, an integrated arc-shaped locking piece matching the outer diameter of the rotating rod is attached to the outside of the winding layer. The locking piece is aligned with the through hole on the rotating rod. Then, a fastening bolt is passed through the locking piece, the winding layer and the rotating rod in sequence and locked, thereby achieving rigid fixation of the bottom of the protective net to the rotating rod.

[0052] Under natural conditions, if slopes are exposed to heavy rainfall or flooding for extended periods, ecological vegetation can be easily damaged. This is especially true when continuous water flow significantly increases the hydrodynamic forces on the stems and leaves of vegetation, making them susceptible to bending and tearing. The swaying of the stems and leaves can also transfer tension to the roots, loosening or even pulling them out. This ultimately leads to substrate loss and damage to the slope structure, seriously compromising the stability and sustainability of the ecological slope protection.

[0053] The protective net designed in this embodiment can cover the slope surface above the ecological vegetation layer before flood warning or heavy rainfall. During the covering process, the protective net forms a flexible limit on the stems and leaves of the vegetation through its own weight and tension, significantly suppressing the violent swinging of the stems and leaves in the water flow, reducing the pulling force transmitted by the stems and leaves to the root system, thereby effectively protecting the stability of the root system and slowing down the loss of the matrix. At the same time, the protective net body has a mesh port, which allows partial passage of water while providing mechanical support, maintains normal drainage of the slope, and improves the durability and ecological function stability of the ecological slope protection system under extreme scouring conditions as a whole. At the same time, the protective net can be stored as a whole in the open groove and firmly connected to the closed cover, effectively avoiding the exposure, aging and loose structure of the protective net when idle, and ensuring that when a flood comes, the protective net can be quickly and completely towed and unfolded to achieve efficient protection.

[0054] Example 2: Combined with the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 , Attachment Figure 6 and attached Figure 7 In addition to the contents of the above embodiments, the control room is an assembled electromechanical control room commonly used in water conservancy and hydropower projects, and the control room is provided with at least four windows communicating with the outside world. The control room is fixedly connected to the top of the slope through a support unit, and the support unit includes at least four bored cast-in-place piles arranged on the top of the slope and a steel fiber reinforced concrete cap cast on the top of each bored cast-in-place pile. The bored cast-in-place piles and the cap are integrally formed. A plurality of bolt sleeves are provided at the bottom of the control room. After the control room is hoisted into place, the bolt sleeves are inserted into the corresponding mounting holes preset in the steel fiber reinforced concrete cap, and epoxy grouting material is injected into the annular gap between the bolt sleeves and the mounting holes to form an anchoring layer. Subsequently, the bottom of the control room is locked and connected to the bolt sleeves by matching connecting screws, thereby achieving a stable and rigid anchoring between the control room and the cap.

[0055] The specific construction process of the bored piles, steel fiber reinforced concrete cap and control room is an existing technology, and reference can be made to existing standard documents: GB50007-2011 "Code for Design of Building Foundations", JGJ94-2008 "Technical Specifications for Building Pile Foundations", GB / T51231-2016 "Technical Standards for Prefabricated Concrete Buildings", SL191-2008 "Code for Design of Hydraulic Concrete Structures", GB55003-2021 "General Specifications for Building and Municipal Foundations", which will not be repeated here;

[0056] The stabilization module includes two first steel cables, two second steel cables, two support columns, two support piers, two first hoisting devices, two second hoisting devices and four rope guide assemblies;

[0057] Among them, one end of each first steel cable is connected to the traction ring through a locking piece, and the other end of the first steel cable is wound around the corresponding first winch device after passing through the control room window; one end of each second steel cable is connected to the fixing ring through a locking piece, and the other end of the second steel cable is wound around the corresponding second winch device after passing through the control room window; two first winch devices are arranged in the control room for winding and releasing the first steel cables; two second winch devices are arranged in the control room for winding and releasing the second steel cables; two support columns are vertically installed on both sides of the bottom of the slope body; two support piers are respectively arranged on both sides of the top of the slope body; four rope guide assemblies are respectively installed on the top of the support columns and the support piers, for guiding the first steel cable or the second steel cable to wind out smoothly.

[0058] The support column is made by drilling a hole at the bottom of the slope body, lowering a prefabricated H-shaped steel column into the hole, and pouring epoxy grouting or cement slurry between the column and the hole. After the slurry solidifies, it forms an integrated structure with the surrounding soil, thereby achieving firm anchoring of the support column to the bottom of the slope body.

[0059] Each supporting pier is made of reinforced concrete or prefabricated alloy steel and is fixed to the foundation at the top of the slope body by embedding anchors.

[0060] like Figure 5 As shown, the rope guide assembly includes a U-shaped bracket installed on the top of a support column or a support pier, a first guide wheel whose axis is rotated to fit in the opening area of ​​the U-shaped bracket, and a second guide wheel whose axis is rotated to fit in the opening area of ​​the U-shaped bracket, wherein the second guide wheel is arranged below the first guide wheel.

[0061] The U-shaped bracket is made of high-strength alloy steel, and the bottom of the U-shaped bracket is fixed to the reinforcing steel plate anchor pre-set on the top of the support column by welding and bolts, thereby achieving firm anchoring between the U-shaped bracket and the support column.

[0062] The first guide wheel and the second guide wheel are respectively rotatably installed in the opening area of ​​the U-shaped bracket through the rotating shaft support. The first guide wheel and the second guide wheel are respectively provided with a rotating shaft passing through the center of the wheel body, and both ends of the rotating shaft pass through the rotating shaft support installed on both sides of the U-shaped bracket to achieve smooth rotation and axial stability of the guide wheels. In addition, the side wall of the U-shaped bracket is provided with a reinforcing hoop to tighten and reinforce the rotating shaft support to improve the structural stability of the rope guide assembly under stress conditions.

[0063] Specifically, one end of the first steel cable is fixedly connected to the traction ring on the closing cover, and then passes through the rope guide assembly on the top of the supporting pier, first passes through the bottom of the second guide wheel, then goes upward from the second guide wheel around its rim, and is led out from the gap between the first guide wheel and the second guide wheel, and finally enters the control room from the window and is wound around the corresponding first winch device.

[0064] like Figure 6 and Figure 7 As shown, one end of the second steel cable is fixedly connected to the fixed ring, and then passes through the rope guide assembly arranged on the top of the support column, is led out through the gap between the first guide wheel and the second guide wheel, and finally enters the control room through the window and is wound around the corresponding second winch device.

[0065] The slope surface is provided with an inwardly concave accommodating groove near the top of the slope, and its shape and size match the base of the closing cover for accommodating the closing cover. The second steel cable drives the closing cover to move upward along the slope surface and stops the closing cover in the accommodating groove.

[0066] Before a flood warning or flood discharge operation is initiated, the first and second hoisting devices in the control room are linked to drive the protective net to unfold and cover the slope to prevent scouring and soil loss on the slope. The specific operation process is as follows:

[0067] S101: The first hoisting device in the control room is activated, pulling and reeling in the first steel cable connected to the bottom of the closing cover. As the first steel cable is gradually reeled in, the closing cover rises vertically from the bottom of the slope until it is aligned with the highest point of the ecological tank. During this process, the protective net connected to the bottom of the closing cover is pulled out of the open tank section by section and unfolds downward under the action of gravity.

[0068] S102: The second hoisting device in the control room is activated to drive the second traction cable connected to the closing cover to reel in. Simultaneously, the first hoisting device is activated to gradually release the first traction cable. The closing cover, pulled by the second cable, moves approximately horizontally toward the top of the slope. The movement path of the closing cover is constrained and guided by the rope guide assembly on the top of the supporting pier. Ultimately, the closing cover is positioned and fixed in a pre-set receiving groove at the top of the slope.

[0069] S103: After the closed cover of the protective net is embedded in the groove at the top of the slope, the protective net maintains an overall tensioned covering state from the top to the bottom of the slope, effectively shielding the slope and reducing the intensity of water scouring. At the same time, it has the dual functions of protecting root plants and reinforcing the slope structure.

[0070] The present invention provides an integrated adaptive drainage and reinforcement ecological slope protection system for water conservancy projects. To address the problems of traditional ecological slopes in extreme working conditions such as floods, such as slow response, weak protection, and easy damage to vegetation, the system innovatively adopts a winch drive and a steel cable coordinated traction method to release the protective net from the open slot in sequence, unfold it in stages along the slope, and complete the tensioning and locking after the closed cover is embedded in the accommodating groove at the top of the slope, forming an overall shielding and stable coverage of the slope. Through the coordinated control of the first and second steel cables during the release process, the protective net is unfolded from the bottom to the top and then transitioned to the tensioning and positioning at the top of the slope, avoiding the shear or friction damage to the slope vegetation caused by the traditional traction and sliding coverage of the protective net from a single direction, thereby effectively limiting the fluttering of stems and leaves, slowing down the impact of water flow, and inhibiting the loss of topsoil, taking into account both ecological restoration and structural reinforcement, and significantly improving the response speed, service life, and ecological adaptability of the ecological slope protection system in complex hydraulic environments.

10. The ecological slope protection system according to claim 9, characterized in that: Before a flood warning or flood discharge operation is initiated, the first and second hoisting devices in the control room are linked to drive the protective net to unfold and cover the slope to prevent scouring and soil loss on the slope. The specific operation process for unfolding the protective net to cover the slope is as follows: S101: The first hoisting device in the control room is activated, pulling and reeling in the first steel cable connected to the bottom of the closing cover. As the first steel cable is gradually reeled in, the closing cover rises vertically from the bottom of the slope until it is aligned with the highest point of the ecological tank. During this process, the protective net connected to the bottom of the closing cover is pulled out of the open tank section by section and unfolds downward under the action of gravity. S102: The second hoisting device in the control room is activated to drive the second traction cable connected to the closing cover to reel in. Simultaneously, the first hoisting device is activated to gradually release the first traction cable. The closing cover, pulled by the second cable, moves approximately horizontally toward the top of the slope. The movement path of the closing cover is constrained and guided by the rope guide assembly on the top of the supporting pier. Ultimately, the closing cover is positioned and fixed in a pre-set receiving groove at the top of the slope. S103: After the closed cover of the protective net is embedded in the groove at the top of the slope, the protective net maintains an overall tensioned covering state from the top to the bottom of the slope, effectively shielding the slope and reducing the intensity of water scouring. At the same time, it has the dual functions of protecting root plants and reinforcing the slope structure.
