Description

Technical Field

[0001] This utility model relates to the field of ecological restoration technology. Background Technology

[0002] Ecological interlocking slope protection is a new type of ecological slope protection that integrates slope protection maintenance and ecological restoration. Its widespread application in landscape architecture can also serve to beautify and decorate the landscape with greenery.

[0003] Existing interlocking slope protection structures, taking CN221702288U as an example, have connecting blocks on one side of the support plate and a first connecting groove on the other side. The first connecting groove on one support plate is used to fit the connecting block on the other support plate to achieve splicing between the two support plates. The bottom and wall of the first connecting groove form an acute angle, allowing the groove wall of the first connecting groove on one support plate to abut against the connecting block on the other support plate in both longitudinal and transverse directions. However, the connecting blocks in this structure are connected by dovetail grooves, which is a movable connection. This structure is prone to local deformation under rainwater impact, such as localized sagging or collapse. In other words, the existing structure has poor overall stability and relatively poor mechanical properties. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a landscape maintenance structure based on ecological restoration, which solves the problems of low connection strength between interlocking bricks in existing interlocking slope protection structures, and the tendency for local deformation and collapse to occur after the interlocking bricks are installed.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] The landscape maintenance structure based on ecological restoration includes a top beam, a bottom beam, a precast concrete frame, and interlocking brick blocks. Planting areas are set within the interlocking brick blocks. The structure is characterized by: the precast concrete frame being a reinforced concrete precast component, with at least two rows of interlocking brick blocks installed within its internal space; the interlocking brick blocks being high-strength steel fiber reinforced concrete precast components without main reinforcement; and each row consisting of two symmetrically arranged interlocking brick blocks. Each interlocking brick block is an arc-shaped precast brick composed of straight side borders and arc-shaped top and bottom borders. The interlocking brick blocks form multiple arc-shaped supports within the precast concrete frame.

[0007] Furthermore, the planting area is a fan-shaped hollow structure located inside the interlocking brick blocks, and the hollow structure is filled with nutrient soil and planted with green plants.

[0008] Furthermore, the side frame of the precast concrete frame is provided with a tongue and groove design, which allows the two precast concrete frames to be formed relatively quickly during splicing and overlapping.

[0009] Furthermore, the side frame of the precast concrete frame is provided with reserved through holes and is fastened with high-strength bolts.

[0010] Furthermore, short reinforcing bars are reserved at both the upper and lower ends of the precast concrete frame, and secondary casting is performed between the top and lower ends and the precast beam at the top of the slope to form a whole.

[0011] Furthermore, the top beam and bottom beam are provided with reserved slots that cooperate with short reinforcing bars.

[0012] Furthermore, fiber cloth or grid cloth or wire mesh is laid on the slope below the precast concrete frame, which can effectively prevent soil erosion.

[0013] Furthermore, the inner surface of the precast concrete frame is provided with a wedge-shaped groove, which engages with the two side frames of the interlocking blocks in a wedge-shaped manner, and a concrete arch beam is provided in the space between the upper and lower rows of interlocking blocks.

[0014] Furthermore, bolt holes are provided between the two interlocking blocks in each row, and steel bars or bolts are used for auxiliary positioning and fixing.

[0015] Furthermore, the two interlocking blocks in each row are connected by dovetail wedges.

[0016] The beneficial effects of this utility model are:

[0017] In this technology, by combining interlocking brick blocks with a precast concrete frame, and forming multiple arc-shaped supports inside the installed frame, the design of an arch bridge is simulated. The arch shape gives the structure higher physical stability and better mechanical bearing capacity.

[0018] The unique design utilizes arc-shaped local supports between adjacent interlocking brick blocks, creating a strong self-locking effect between the interlocking blocks and with the precast concrete frame. This ensures high overall stability even under severe erosion conditions such as heavy rain. Furthermore, the growth of vegetation within the perforated holes of the interlocking brick blocks further enhances the slope's durability and stability, while also protecting the ecological environment and enhancing the aesthetic appeal of the vegetation.

[0019] This technology enables rapid construction by using prefabricated components and local secondary mortar pouring at connection nodes. Therefore, compared with traditional production and paving, this technology has higher implementation efficiency and improved stability, integrity, durability, wind and wave resistance, and erosion resistance. At the same time, the large-scale planting of greenery can effectively achieve ecological restoration of barren slopes and other slope locations.

[0020] The effects of this technology will be further illustrated below with specific embodiments and construction processes. Attached Figure Description

[0036] Example 1

[0037] The landscape maintenance structure based on ecological restoration includes a precast concrete frame, interlocking blocks, and planting areas set in the interlocking blocks for shrubs or hardy grasses. The precast concrete frame is laid on the slope foundation and has a long length, customized according to the slope length of the slope.

[0038] This embodiment will be described in conjunction with the appendix to the instruction manual. Figure 1 To be continued Figure 7 A detailed explanation will be provided.

[0039] The precast concrete frame 10 has a long length and a narrow width, and is an overall rectangular frame structure. In the width direction, multiple rows of paired and symmetrically arranged interlocking brick blocks 20 can be installed within the space of the precast concrete frame 10. These interlocking brick blocks 20 are high-strength steel fiber reinforced concrete without main reinforcement and are formed using a precast molding process. In the length direction, multiple rows of interlocking brick blocks are arranged to fully fill the aforementioned precast concrete frame 10.

[0040] In this embodiment, the interlocking block 20 has straight side frames 21 on both sides and curved side frames 22 on the top and bottom, with chamfers 23 at the corners. Through the above structure, a fan-shaped hollow structure 24 is formed inside the interlocking block, which is also the area for nutrient soil backfilling and planting.

[0041] Meanwhile, bolt holes 25 are provided between two pairs of interlocking blocks 20, and steel bars or bolts are used for auxiliary positioning and fixing.

[0042] The aforementioned precast concrete frame 10 has a large size, therefore it is a precast reinforced concrete component with a steel cage or steel mesh inside, which gives it better mechanical properties, including tensile mechanical properties and bending mechanical properties.

[0043] A tongue and groove design 11 is provided on the side frame of the aforementioned precast concrete frame 10, which enables the two precast concrete frames to be formed relatively quickly during splicing and overlapping.

[0044] Furthermore, a reserved perforation 12 is provided on the side frame of the aforementioned precast concrete frame 10. The reserved perforation is used for reinforcement between two precast concrete frames, for example, by connecting them with high-strength bolts, so that after the multiple precast concrete frames are paved, they form a grid structure composed of multiple precast concrete frames.

[0045] The upper end of the aforementioned precast concrete frame 10 is reserved with short reinforcing bars 13. These short reinforcing bars are bent into an L-shape and are connected to the precast beam at the top of the slope by secondary casting to form an integral whole.

[0046] The lower end of the aforementioned precast concrete frame 10 is reserved with short reinforcing bars 13. These short reinforcing bars are bent into an L-shape and are connected to the precast beam at the bottom of the slope by secondary casting to form a whole.

[0047] In the steps prior to the installation of the precast concrete frame, fiber cloth or grid cloth or wire mesh is laid on the slope in advance. This fiber cloth or grid cloth can effectively prevent soil erosion.

[0048] The construction method of this utility model is as follows:

[0049] The first step is to clean, correct, and compact the soil layer on the slope, and dig beam trenches at the top and bottom of the slope. The top beam 30 and bottom beam 40 are assembled and constructed at the top and bottom of the slope. The top beam and bottom beam are provided with reserved slots 31. These reserved slots are in the style of the Great Wall crenellations and are used for secondary pouring and connection, that is, to fix and connect with the precast concrete frame.

[0050] The second step is to further modify the slope after the top and bottom beams have been cured and hardened, and then lay 50 mm of nutrient-rich geotextile or wire mesh.

[0051] The third step involves overlapping the upper and lower ends of the precast concrete frame onto the top and bottom beams, respectively, and inserting the pre-reserved reinforcing bars at both ends of the precast concrete frame into the pre-reserved slots 31 in the top and bottom beams for fixing. Further, the precast concrete frame is continuously laid and connected using bolt assemblies, awaiting the installation of the interlocking brick blocks.

[0052] The fourth step is to lay the interlocking bricks in pairs inside the precast concrete frame. During the laying process, high-strength bolts are used to connect the pairs of interlocking bricks 20 laterally. After connection, the interlocking bricks in pairs are laid. This laying process is carried out layer by layer from bottom to top until all interlocking bricks in the frame are laid.

[0053] The fifth step involves filling the pre-reserved slots in the top and bottom beams with mortar, and simultaneously filling the gaps between the interlocking bricks and the precast concrete frame with 60mm of mortar. After curing, the interlocking bricks and the precast concrete frame form an integrated structure. The interlocking bricks create multiple arc-shaped supports within the precast concrete frame. These arc-shaped supports, with the ends of the interlocking bricks resting against the inner edge of the precast concrete frame, effectively improve the overall load-bearing capacity of the slope protection, especially its mechanical properties, and effectively solve the problem of easy deformation and displacement of the interlocking bricks. Furthermore, after filling the interior with nutrient soil and being washed by rainwater, the interlocking bricks will become increasingly compacted, forming a unified structure.

[0054] The sixth step involves backfilling the hollowed-out areas of the interlocking brick blocks with nutrient-rich soil, spraying with mud containing plant seeds, or transplanting shrub seedlings, and then watering to promote the growth of greenery. This structural construction process is simple and efficient, effectively improving soil conditions on slopes, and the greenery has strong water and fertilizer retention capabilities, preventing soil fertility degradation.

[0055] After completing the above six steps and maintaining the greenery for several months, a lush vegetation slope will be formed, resulting in a significant beautification effect.

[0056] Example 2

[0057] Refer to the instruction manual. Figure 8The difference between this embodiment and Embodiment 1 is that the overlap surface between the interlocking blocks and the precast concrete frame has been locally optimized. Specifically, a wedge-shaped groove 51 is pre-formed on the inner surface of the precast concrete frame. This wedge-shaped groove is used to engage with the two side frames of the interlocking blocks in a wedge-shaped locking manner. This structure enables rapid positioning of the interlocking blocks. Another advantage of this structure is that, through the positioning of the wedge-shaped groove, the interlocking blocks in the upper and lower rows do not contact each other, eliminating stress and maintaining a certain spacing. Mortar 60 is filled within this spacing. After hardening, the mortar can form an upwardly convex arched beam, which can further improve the stability of this frame slope protection structure.

[0058] Furthermore, in this embodiment, the overlap between the two paired interlocking blocks is connected using dovetail wedges 50. Specifically, a dovetail groove is provided between the two interlocking blocks, and the dovetail wedges are used for quick fixing, thus achieving the function of tightening bolts.

[0059] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Without departing from the spirit of the present utility model, all modifications and improvements to the present utility model by those skilled in the art should fall within the protection scope defined by the claims of the present utility model.
