Description

Technical Field

[0001] This invention relates to the field of roadside slope greening and protection technology, and in particular to an outdoor three-dimensional greening and protection device. Background Technology

[0002] Outdoor vertical greening is an important technical form for urban ecological construction and outdoor soil and rock slope management. It can take into account both slope structure protection and ecological landscape restoration, and is widely used in outdoor exposed slopes, fence facades, and site slopes. Among them, road slopes are a key application area for outdoor vertical greening.

[0003] Stepped stacked planting bags are a commonly used technique for ecological greening of roadside slopes. Existing stepped stacked planting bags use eco-bags filled with planting soil, stacked in a staggered, stepped manner along the slope from bottom to top. This method is convenient to assemble and construct, highly adaptable to the site, and allows for rapid slope revegetation. The bags' own weight and interlayer compression create a continuous stepped slope. Combined with the interwoven root systems of the vegetation inside the bags, it achieves shallow soil stabilization and mild erosion prevention. The project cost is moderate, making it widely used in ecological restoration of roadside slopes.

[0004] The existing stepped stacked planting bags have obvious core defects. Their stepped stacking structure relies solely on the weight of the bags themselves and the friction between layers for restraint, without a dedicated interlayer tie and overall constraint structure. This results in insufficient overall stability of roadside slope protection, making them prone to slippage and displacement under the impact of runoff and slope settlement. At the same time, the existing structure lacks a reasonable directional drainage design, and rainwater easily accumulates and stagnates between the bags. This not only affects the normal growth of vegetation but also softens the slope soil and reduces the interlayer friction coefficient, further exacerbating the risk of slope slippage and collapse, creating a vicious cycle of hidden dangers in slope protection.

[0005] In summary, while existing stepped stacked planting bags can achieve simple revegetation of roadside slopes, they have technical shortcomings, such as relying solely on friction between layers, resulting in poor protection reliability and poor drainage, which in turn exacerbates slope instability. They cannot simultaneously meet the practical needs of roadside slope structural safety protection and long-term three-dimensional greening. Summary of the Invention

[0006] This invention provides an outdoor three-dimensional greening protection device that can solve the problems in the prior art where the stepped stacking of planting bags relies solely on friction, resulting in poor protection reliability and poor drainage that exacerbates slope instability.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: an outdoor three-dimensional greening protection device, including an installation frame, wherein a number of placement frames are rotatably connected to the inner side of the installation frame via a shaft, the number of placement frames are arranged in a stepped layer, and a number of downward recessed grooves extending along the width direction of the placement frame are provided on the bottom plate of the placement frame, the grooves forming directional drainage channels. Each layer of the placement frame has a drain pipe at the outer end of the groove. The drain pipe is a rigid pipe. The bottom end of the drain pipe on the upper layer of the placement frame extends into the groove of the lower layer of the placement frame. The drain pipe simultaneously serves to guide water and limit contact between the upper and lower layers of the placement frame.

[0008] Preferably, a constraint sleeve is fixedly connected to the groove of the placement frame, and the bottom end of the drain pipe on the upper placement frame is inserted into the constraint sleeve.

[0009] Preferably, a plurality of drainage holes are provided on the outer side of the lower end of the drain pipe.

[0010] Preferably, the mounting frame is provided with a mounting groove, and a plurality of mounting seats are adjustablely arranged in the mounting groove, with the shaft rotatably connected to the mounting seats.

[0011] Preferably, an adjustment shaft is rotatably connected within the mounting groove, and the adjustment shaft is threadedly connected to the mounting base.

[0012] Preferably, the inner end of the placement frame is threaded with an anchoring cone rod, which is disposed in the groove inside the placement frame.

[0013] Preferably, the bottom plate of the placement frame has a plurality of through holes evenly distributed.

[0014] Compared to existing technologies, this invention fixes the installation frame to the roadside slope, and multiple placement frames are rotatably connected to the installation frame via shafts, allowing for a stepped, layered arrangement that adapts to the slope gradient. The grooves in the bottom plate of the placement frame form directional drainage channels, quickly diverting rainwater to prevent waterlogging of the planting soil and slope soil. The downward-protruding structure also increases interlayer contact friction, enhancing anti-slip performance. Rigid drainage pipes guide the upper layer of accumulated water step-by-step into the lower grooves, achieving orderly drainage and preventing water from softening the soil and reducing the friction coefficient. Simultaneously, the rigid pipes act as rigid components, providing contact and restraint between the upper and lower placement frames, replacing the traditional method of restraint relying solely on weight and friction. This effectively solves the problems of poor reliability and inadequate drainage exacerbating slope instability associated with existing stepped planting bags, significantly improving the structural stability and drainage of roadside greening protection.

[0017] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the technical solution of this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0018] like Figures 1 to 2 As shown, the present invention provides an outdoor three-dimensional greening protection device, including an installation frame 1. The inner side of the installation frame 1 is rotatably connected to a number of placement frames 3 via a shaft 2. The number of placement frames 3 are arranged in a stepped layer. The bottom plate of the placement frame 3 is provided with a number of downward recessed grooves 8 that extend along the width direction of the placement frame 3. The grooves 8 form directional drainage channels. Each layer of the placement frame 3 has a drain pipe 4 at the outer end of the groove 8. The drain pipe 4 is a rigid pipe. The bottom end of the drain pipe 4 on the upper layer of the placement frame 3 extends into the groove 8 of the lower layer of the placement frame 3. The drain pipe 4 simultaneously serves to guide water and limit contact between the upper and lower layers of the placement frame 3.

[0019] Specifically, the mounting frame 1, as the basic load-bearing component of the entire device, is mainly used to fix it to the roadside slope and provide an installation benchmark for other components. It can be made of galvanized steel plate, aluminum alloy profile or high-strength engineering plastic, and has sufficient structural strength and weather resistance. When setting it up, it should be ensured that the mounting frame 1 fits tightly to the slope surface to improve the overall fixing stability. Anchoring ear plates 101 can be added to the side of the mounting frame 1 for inserting anchor rods to firmly anchor the device to the slope rock and soil. Specifically, an integrated rectangular frame or a segmented assembled frame structure can be adopted to adapt to the needs of slope greening layout of different sizes.

[0020] The shaft 2 is used to realize the rotational connection between the mounting frame 1 and the placement frame 3, so that the placement frame 3 can freely adjust its tilt angle relative to the mounting frame 1 to adapt to road slopes with different gradients. It is usually made of wear-resistant and rust-proof materials such as stainless steel and galvanized round steel. It should be noted that the fit clearance between the shaft 2 and the mounting frame 1 and the placement frame 3 should be moderate to ensure smooth rotation without jamming, while avoiding excessive clearance that would cause the placement frame 3 to wobble. Specifically, structures such as a smooth shaft or a pin with a limiting step can be used to meet the core requirements of rotational connection and angle adjustment.

[0021] The placement frame 3 is a carrier for directly holding planting bags or filling with planting soil. It is arranged in a stepped layer along the height of the installation frame 1 to form a three-dimensional green space. The materials used are consistent with those of the installation frame 1 to ensure that the overall structure can work together to bear the load. When setting it up, the spacing between the layers of each group of placement frames 3 should be uniform and the steps should be arranged in a regular manner to provide a stable space for vegetation growth. Specifically, an integrated trough structure or a modular structure with side enclosures can be used to meet the usage requirements of different planting scenarios.

[0022] The groove 8 is set on the bottom plate of the placement frame 3 and extends along the length of the placement frame 3. It has the dual functions of directional drainage and increasing interlayer friction. It is integrally formed with the placement frame 3 to ensure the integrity of the structure. When setting it, the groove 8 should be recessed downward and run through both ends of the placement frame 3 to form a continuous directional drainage channel. At the same time, the downward protruding part can increase the interlayer contact friction and improve the anti-slip ability. Specifically, arc-shaped grooves, rectangular grooves and other structures can be used, all of which can achieve the core effects of drainage and friction enhancement.

[0023] The drainage pipe 4 is a rigid pipe located at the outer end of the groove 8 of each layer of the placement frame 3. Its core function is to provide both tiered water guidance and to limit the contact between the upper and lower placement frames 3. It can be made of rigid PVC, stainless steel, or high-strength engineering plastic, possessing sufficient rigidity and outdoor weather resistance. It should be noted that the bottom end of the upper drainage pipe 4 must accurately extend into the groove 8 of the lower placement frame 3 to ensure smooth drainage and reliable contact. During installation, the drainage pipe 4 can be inserted directly into the planting bag or planting soil after placing a planting bag or filling it with planting soil within the placement frame 3. The wrapping and restraining effect of the planting bag or planting soil further enhances the anchoring effect of the drainage pipe 4, preventing it from loosening, shifting, or falling off. Specifically, cylindrical or tapered rigid pipe structures can be used, both achieving the combined functions of water guidance, limiting, and enhanced anchoring.

[0024] In practical use, the installation frame 1 is first fixed to the roadside slope. Multiple sets of placement frames 3 are rotatably connected to the installation frame 1 through the shaft 2, so that each set of placement frames 3 is arranged in a stepped layer along the height direction of the installation frame 1 and adapted to the slope. Planting bags or planting soil are placed in the placement frames 3 to complete the greening layout. When it rains, rainwater flows into the directional drainage channel formed by the groove 8 on the bottom plate of the placement frame 3. The water is guided layer by layer to the lower groove 8 through the rigid drainage pipe 4 at the outer end of each layer of groove 8 to achieve orderly drainage. At the same time, the drainage pipe 4 forms a contact limit for the upper and lower adjacent placement frames 3, and the groove 8 increases the interlayer friction through the downward protruding structure, which together ensures the structural stability of the slope greening protection.

[0025] like Figures 1 to 2 As shown, in order to solve the problem of easy displacement and failure of the abutment limit of the drain pipe 4, which in turn aggravates the slippage and instability between layers, preferably, a constraint sleeve 6 is fixedly connected in the groove 8 of the placement frame 3, and the bottom end of the drain pipe 4 on the upper placement frame 3 is inserted into the constraint sleeve 6.

[0026] Specifically, the constraint sleeve 6 can directionally connect and rigidly constrain the bottom end of the drainage pipe 4, preventing the drainage pipe 4 from shifting, slipping or misaligning under the impact of rainwater and the squeezing of soil. This ensures that the drainage pipe 4 is always accurately abutted in the groove 8 of the lower placement frame 3, continuously and stably playing the role of water guiding and interlayer limiting, further strengthening the anti-slip capability of the device, and eliminating the problem of protective instability caused by limiting failure.

[0027] The constraint sleeve 6 is used to position the bottom end of the drain pipe 4. It is a special component that improves the stability of the drain pipe 4 insertion. It can be made of rigid PVC, stainless steel or engineering plastic that matches the drain pipe 4, and has good insertion accuracy and structural strength. It should be noted that the constraint sleeve 6 needs to be fixed in the center of the groove 8, and the inner diameter should match the outer diameter of the drain pipe 4 to ensure a tight and non-loose insertion. Specifically, a straight sleeve or a tapered sleeve structure can be used to achieve directional constraint on the drain pipe 4.

[0028] like Figures 1 to 3 As shown, in order to solve the problem that the bottom of the drainage pipe 4 is easily blocked by soil, resulting in poor drainage and thus softening the soil and aggravating slope instability, preferably, a number of drainage holes 5 are opened on the outer side of the lower end of the drainage pipe 4.

[0029] Specifically, the drainage hole 5 can divert the accumulated water inside the drainage pipe 4 to the side, preventing the bottom of the drainage pipe 4 from being blocked by planting soil and debris, thus preventing water accumulation. This ensures that the tiered drainage channels remain unobstructed, preventing soil softening and reduced interlayer friction caused by drainage obstruction. It also breaks the vicious cycle of "poor drainage - increased instability" from the source, ensuring that drainage and protection functions are stable simultaneously.

[0030] Drainage holes 5 are located on the outer side of the lower end of drainage pipe 4 to achieve lateral drainage of drainage pipe 4 and prevent blockage at the bottom. When setting them, drainage holes 5 should be evenly distributed around the lower end of drainage pipe 4, and the hole diameter should be moderate to ensure drainage efficiency and prevent a large amount of soil from flowing in. Specifically, circular holes or elliptical holes can be used, both of which can achieve the effect of lateral drainage and anti-blockage.

[0031] like Figures 3 to 5 As shown, in order to solve the problem that the spacing and tilt angle of the placement frame 3 are not adjustable and cannot be adapted to road slopes of different sizes and slopes, preferably, the installation frame 1 is provided with an installation groove 102, and a number of installation seats 104 are adjustablely arranged in the installation groove 102, and the shaft 2 is rotatably connected to the installation seat 104.

[0032] Specifically, the mounting slot 102 works in conjunction with the position-adjustable mounting base 104 to flexibly adjust the installation height, interlayer distance and tilt angle of the placement frame 3, adapting to the construction needs of roadside slopes with different slopes and heights, greatly improving the on-site versatility and adaptability of the device, while ensuring that the stepped layered arrangement of the placement frame 3 is more regular, improving the overall structural stability and the aesthetics of the greening.

[0033] The mounting groove 102 is set on the mounting frame 1 to provide movement guidance and installation space for the mounting base 104. It is integrally formed with the mounting frame 1 and is made of high-strength materials such as galvanized steel plate and aluminum alloy. It should be noted that the length of the mounting groove 102 must meet the adjustment stroke of the mounting base 104, and the groove wall must be flat and burr-free to ensure smooth movement of the mounting base 104. Specifically, an open slide groove or a closed guide rail structure can be adopted. The mounting base 104 is set in the mounting groove 102 and is used to connect the shaft 2 and drive the placement frame 3 to adjust its position. The material is the same as that of the mounting frame 1 to ensure structural strength. When setting it up, it should be ensured that the mounting base 104 fits snugly against the inner wall of the mounting groove 102 without any wobbling or gap. Specifically, three structures can be used to achieve positional adjustment: sliding mounting base, snap-fit ​​mounting base, and threaded adapter mounting base. The outer wall of the sliding mounting base slides against the inner wall of the mounting groove 102, and the position is adjusted by its own sliding fit. When setting it up, the fit between the mounting base and the mounting groove should be ensured. The gaps are uniform, with no jamming or shaking; the snap-fit ​​mounting base has a built-in elastic locking block, and the inner wall of the mounting groove 102 has a corresponding positioning slot. Positioning and adjustment are achieved by the engagement of the locking block and the slot. It should be noted that the elasticity of the locking block is moderate, which facilitates adjustment and ensures firm positioning; the threaded adapter mounting base has a threaded hole in the center, which can be used with threaded rods to achieve precise adjustment, and reserves a structural foundation for the subsequent adaptation of the adjustment shaft 103; all three structures can independently achieve the adjustable installation of the mounting base 104, and can be flexibly selected according to the accuracy requirements of slope construction.

[0034] like Figures 3 to 5As shown, in order to solve the problem of low adjustment accuracy and uneven arrangement of the spacing of the placement frame 3, which leads to a chaotic step layout and affects the protective effect, preferably, an adjustment shaft 103 is rotatably connected in the mounting groove 103, and the adjustment shaft 103 is threadedly connected to the mounting base 104.

[0035] Specifically, the control shaft 103 is threadedly connected to the mounting base 104, which can precisely control the movement distance and position of the mounting base 104, ensuring that the layer spacing of each group of placement frames 3 is uniform and consistent, without the need for individual adjustment, improving on-site installation efficiency and construction standardization, making the stepped layout more regular, and further optimizing the structural stability and drainage layout of the device.

[0036] The adjusting shaft 103 is rotatably connected in the mounting groove 102 and is used to precisely adjust the position of the mounting seat 104. It is made of wear-resistant and rust-proof materials such as stainless steel and galvanized round steel. It should be noted that the threaded section of the adjusting shaft 103 must precisely mesh with the mounting seat 104 and rotate smoothly without jamming. Specifically, a single multi-segment variable pitch threaded shaft or a single independent threaded shaft structure can be used to achieve precise adjustment of the mounting seat 104.

[0037] The single multi-segment variable pitch threaded shaft 103 is an integral threaded rod rotatably connected within the mounting groove 102. Several threaded segments with gradually increasing thread pitch are machined on the shaft. Each threaded segment corresponds to a mounting seat 104. This is primarily used to achieve synchronous adjustment of all mounting seats 104 through a single rotation, ensuring that the interlayer distance between each set of placement frames 3 remains uniform. It is made of wear-resistant and rust-proof materials such as stainless steel and galvanized round steel. It should be noted that the increment in thread pitch of each segment must match the design requirements of the step spacing of the placement frame 3, and the thread machining accuracy must meet the standards to ensure precise movement of each mounting seat 104 during rotation. This structure is an integrated control structure; only one threaded shaft needs to be rotated to complete the spacing calibration of all placement frames 3, making it suitable for standardized, large-scale road slope construction scenarios.

[0038] The single-seat, single-threaded shaft 103 refers to each mounting seat 104 having its own independent threaded shaft. Each threaded shaft is rotatably connected within the mounting groove 102 and threadedly connected to the corresponding mounting seat 104. It is mainly used for independent and free position adjustment of a single mounting seat 104, adapting to the construction needs of irregular slopes and non-standard slopes. The material selection is consistent with that of the multi-segment variable pitch threaded shaft, ensuring wear-resistant and rust-proof performance. It should be noted that the independent threaded shafts do not interfere with each other. During adjustment, the movement distance and position of the corresponding mounting seat 104 can be controlled independently, meeting the personalized adjustment needs of the tilt angle and layer spacing of the frame 3 placed in different positions. This structure has high adjustment flexibility and can adapt to complex road slope conditions with irregular undulations and varying slopes.

[0039] like Figure 6As shown, in order to solve the problem that the overall anchoring strength of the placement frame 3 is insufficient and the overall slippage is easy to occur due to the fixation of the placement frame 3 by interlayer constraints alone, preferably, the inner end of the placement frame 3 is threaded with an anchoring cone rod 7, and the anchoring cone rod 7 is set in the groove 8 inside the placement frame 3.

[0040] Specifically, the anchoring cone 7 can be directly driven into the interior of the roadside slope, rigidly connecting the placement frame 3 to the slope rock and soil to form an auxiliary anchoring structure. Combined with the drainage pipe 4 for contact and limit, and the groove 8 for friction enhancement, a triple protection system is constructed, which greatly improves the overall anchoring stability of the device, effectively resists the impact of rainwater runoff and slope settlement, and completely solves the defect of insufficient protection between layers relying solely on friction.

[0041] The anchoring cone 7 is threaded to the inner end of the placement frame 3 and is used to anchor the placement frame 3 to the slope. It is made of rust-proof and wear-resistant materials such as stainless steel and high-strength carbon steel. It should be noted that the anchoring cone 7 should be aligned with the groove 8 and driven into the slope to a depth not less than the design value to ensure a firm anchoring.

[0042] like Figure 6 As shown, in order to solve the problems that the vegetation roots cannot penetrate deep into the slope, resulting in poor ecological soil stabilization and insufficient long-term protection stability, preferably, a number of through holes 301 are evenly opened on the bottom plate of the placement frame 3.

[0043] Specifically, the through hole 301 allows vegetation roots to pass through the placement frame 3 and penetrate the slope, achieving a three-in-one anchoring of the device, vegetation, and slope, which greatly improves the long-term ecological soil stabilization effect. In the early stage, the use of non-woven fabric can prevent soil loss in the placement frame 3. Later, when the vegetation roots develop, they will break through the non-woven fabric and naturally stabilize the slope through the through hole 301, taking into account both construction convenience and long-term ecological protection capabilities.

[0044] Through holes 301 are evenly opened on the bottom plate of the placement frame 3 to allow vegetation roots to penetrate and penetrate the slope. The hole diameter is moderate and the distribution is even. When setting them, it should be ensured that the through holes 301 avoid the core drainage area of ​​the groove 8 so as not to affect the smooth flow of drainage channels. Specifically, circular through holes or strip through hole structures can be used, both of which can meet the needs of root penetration and soil protection.

[0045] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
