Technical Field

[0001] This invention relates to the technical field of landscape terrace construction, specifically to a landscape terrace structure with a wire mesh sprayed layer and its construction method. Background Technology

[0002] Traditional landscape terrace construction often employs simple masonry or earthwork piling methods. For example, while rubble retaining walls offer good structural stability, their exposed surfaces lack a foundation for vegetation growth, resulting in poor surface ecological stability. Earthwork piles are also susceptible to rainwater erosion, leading to soil loss. Furthermore, due to significant elevation differences, these structures are prone to landslides or collapses. In addition, existing technologies lack a structurally stable landscape terrace structure and an efficient construction method that integrates structural support, slope protection, and rapid vegetation restoration.

The front edge of each multi-level terrace is constructed with a retaining wall arranged in a backward-sloping manner. The outer surface of the retaining wall is anchored with wire mesh, and the wire mesh is anchored in the retaining wall by steel bar hooks. The outer surface of the retaining wall is also sprayed with a layer of sprayed concrete, and the wire mesh is buried in the sprayed concrete layer and forms a wire mesh sprayed concrete layer on the outer surface of the retaining wall. The base surface of each multi-level terrace is covered with a planting soil layer. The upper end face of the retaining wall is flush with or exceeds the upper surface of the adjacent planting soil layer by a predetermined height.

[0025] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0026] Example 1 like Figures 1-5 As shown, this embodiment of a landscape terrace structure with a wire mesh sprayed concrete layer includes a multi-level terrace 1 forming a stepped structure. The front edge of the multi-level terrace 1 is constructed with a retaining wall 2 arranged in a backward-sloping manner. The outer surface of the retaining wall 2 is anchored with a wire mesh 21, which is anchored in the retaining wall 2 by a steel bar hook 4. The outer surface of the retaining wall 2 is also sprayed with a layer of sprayed concrete 22, and the wire mesh 21 is buried in the sprayed concrete 22, forming a wire mesh sprayed concrete layer 23 on the outer surface of the retaining wall 2. The base surface of the multi-level terrace 1 is covered with a planting soil layer 3. The upper end face of the retaining wall 2 is flush with or exceeds the upper surface of the adjacent planting soil layer 3 by a predetermined height. The lower end of the retaining wall 2 is embedded in the base surface 11 of the adjacent terrace 1 and is covered by the planting soil layer on the base surface 11 of the terrace 1.

[0027] Specifically, in this embodiment, the wire mesh 21 is anchored within the retaining wall 2 by multiple steel bar hooks 4. The spacing between two adjacent steel bar hooks 4 is approximately 500mm along both the vertical and horizontal directions of the wall. One end of each steel bar hook is inserted into the retaining wall for anchoring, while the other end protrudes from the wall surface for subsequent connection of the wire mesh. The wire mesh can be made of No. 14 galvanized iron wire.

[0028] like Figure 4 and Figure 5 As shown, in this embodiment, the front and upper surfaces of the retaining wall 2 are both covered with the wire mesh sprayed composite layer 23. This ensures that all exposed areas of the retaining wall are covered with wire mesh sprayed composite, improving the overall ecological stability and consistency of the retaining wall.

[0029] In this embodiment, the spray-mixed layer 22 can be made of commonly used plant substrates, which can be solidified on the wire mesh and have air permeability, thus meeting the needs of plant growth.

[0030] This embodiment features a landscape terrace structure with a wire mesh sprayed concrete layer. By setting up retaining walls and applying a wire mesh sprayed concrete layer to the outer surface of the retaining walls, the problem of poor ecological stability of stone masonry terraces and easy erosion and collapse of earthen masonry terraces is solved. This enables the rapid and stable formation of the terrace structure and provides a good growing base for surface crops, thereby improving the overall landscape effect and ecological stability.

[0031] This embodiment features a landscape terrace structure with strong stability and excellent ecological benefits, achieved through a combination of wire mesh and sprayed concrete. The wire mesh is securely connected to the rubble retaining wall via pre-embedded steel hooks, and then a 10cm thick layer of the mixed material is sprayed on top, forming a composite support system of "wall + mesh + sprayed layer," significantly improving erosion resistance and stability. The surface sprayed concrete layer solidifies the wall surface and provides a certain degree of permeability. Combined with the planting soil layer, it provides a good growing environment for crops such as upland rice, achieving integration of engineering protection and agricultural planting.

[0032] Example 2 This embodiment provides a preferred structure for a rebar hook, such as... Figure 4 and Figure 5 As shown, the two ends of the rebar hook 4 are bent to form an anchoring section 41 and a connecting section 42, respectively. The anchoring section 41 and the connecting section 42 have different orientations. The anchoring section 41 is anchored into the retaining wall 2, and the connecting section 42 is tied or welded to the wire mesh 21. The bending of the two ends of the rebar hook to form the anchoring section and the connecting section facilitates anchoring into the retaining wall and also facilitates fixing to the wire mesh, thus improving the stability of the wire mesh connection.

[0033] Optionally, both the anchoring section 41 and the connecting section 42 are arranged perpendicular to the central structure of the steel bar hook 4, and the anchoring section 41 and the connecting section 42 are oriented in opposite directions.

[0034] Example 3 Based on Embodiment 1 or Embodiment 2, this embodiment provides a preferred drainage structure for the retaining wall 2, such as... Figure 3 As shown, multiple drainage pipes 5 are embedded within the retaining wall 2. These drainage pipes 5 are arranged sequentially at intervals along the length of the retaining wall 2, with a spacing of 2m to 3m between adjacent pipes. The drainage pipes 5 penetrate the retaining wall 2 from front to back, with one end connected to the interior of the retaining wall 2 and the other end connected to the exterior. By installing multiple drainage pipes, water accumulation behind the retaining wall can be effectively drained, reducing the impact of water pressure on the retaining wall.

[0035] like Figure 3As shown, in a preferred embodiment, the retaining wall 2 is provided with a reverse filter structure 51, and each drainage pipe 5 is provided with a reverse filter structure 51 at a corresponding position, with one end of the drainage pipe 5 corresponding to the lower end of the reverse filter structure 51. By setting the reverse filter structure, the water entering the drainage pipe can be filtered.

[0036] like Figure 3 As shown, a further embodiment of this solution is that the retaining wall 2 is further provided with a rammed clay layer 52, and each of the filter structures 51 is provided with the rammed clay layer 52 below it.

[0037] Specifically, such as Figure 3 As shown, the other end of the drainage pipe 5 is located above the adjacent planting soil layer 3, and the height difference between the other end of the drainage pipe 5 and the upper surface of the adjacent planting soil layer 3 is 0.3~0.5m; the drainage pipe 5 is arranged to extend downward from back to front, the inward slope of the drainage pipe 5 is not less than 5%, and the water inlet at one end of the drainage pipe 5 is wrapped with a geotextile filter layer.

[0038] Drainage pipe 5 can be made of PVC pipe with a diameter of 50mm~80mm and an inward slope of not less than 5%. The inlet is wrapped with a geotextile filter layer to effectively drain water behind the wall and reduce the impact of water pressure on the wall.

[0039] Example 4 Based on any of the above embodiments, this embodiment provides a specific arrangement for the retaining wall 2. The retaining wall 2 has a partition joint every 9-11 meters along its length. The partition joints are arranged vertically along the wall body of the retaining wall 2, running forward and backward. The partition joints are filled with polyethylene foam boards. By setting partition joints and filling them with polyethylene foam boards, cracking of the wall caused by temperature changes or uneven foundation settlement can be prevented.

[0040] Example 5 Based on any of the above embodiments, this embodiment provides an optional formulation for the spray-mixed layer 22. The raw materials of the spray-mixed layer 22 include 350-450 kg of cement, 80-120 kg of plastering curing agent, 2.5-5 kg ​​of water-reducing agent, 2400-2600 kg of planting soil, 350-450 kg of water, and 20-30 kg of grass seeds. The proportions of each raw material in the spray-mixed layer can be adjusted as needed.

[0041] After the raw materials for the sprayed concrete layer are mixed and stirred evenly as needed, they are sprayed evenly onto the surface of the retaining wall with wire mesh using a spraying device, with a spray thickness of 10cm. The spraying is carried out in two stages to ensure that the mixture densely fills the gaps in the wire mesh and completely covers the reinforcing bar hooks, forming a sprayed concrete layer with a certain strength and thickness.

[0044] During the construction of retaining wall 2, a separation joint is set every 9-11m (preferably 10m) along the length of retaining wall 2, and the separation joint is filled with polyethylene foam board. Simultaneously, multiple drainage pipes 5 are pre-embedded within the retaining wall 2, arranged sequentially at intervals along the length of the retaining wall 2. Multiple sets of filter layers are set on the inner side of retaining wall 2, with each drainage pipe 5 corresponding to one filter layer. The filter layer includes a filter structure 51 and a rammed clay layer 52. The filter structure 51 is located above the rammed clay layer 52, and each filter structure 51 is located below the rammed clay layer 52. A filter structure 51 is positioned corresponding to each drainage pipe 5, with one end of the drainage pipe 5 corresponding to the lower end of the filter structure 51. The filter structure 51 can be formed by wrapping small gravel, sand, etc., with geotextile to create a filter structure with soil filtering function. The rammed clay layer 52 is located below the filter structure 51 and is used to support the filter structure 51.

[0045] S3, Cover with wire mesh 21; After the retaining wall 2 is built, wire mesh 21 is fully laid on the outer surface of the retaining wall 2.

Based on the survey and layout results, a small excavator is used in conjunction with manual labor to excavate in stages from top to bottom. The excavation height of each stage is controlled between 1.5m and 2.5m. The excavated surface is smoothed and leveled, and loose soil, boulders, and plant roots are removed from the slope. After the excavation is completed, the base is compacted to a compaction degree of not less than 0.93. After passing on-site inspection, the next process begins.

The strength of the rubble should not be less than MU30, and M10 cement mortar should be used. The retaining wall should have a top width of 0.6m, a bottom width of 1.2m, a height of 1.8m~2.2m, and a embedment depth of not less than 0.5m. During construction, the walls should be laid in staggered layers, with full mortar application, resulting in a smooth wall surface.

Spraying is done in layers from bottom to top, each layer being 3cm~4cm thick, with a final spray thickness of 10cm. During spraying, the nozzle is perpendicular to the wall surface, at a distance of 1.0m~1.5m. After spraying, manual finishing is performed immediately to ensure the surface flatness deviation does not exceed ±10mm. A curing film is then applied over the sprayed layer for 7 days to maintain moisture.

[0055] S5, Backfill with planting soil; After the initial setting of the mixture, and once the sprayed layer strength reaches 70% of the design value, backfill with planting soil on the inner side of the terrace. The planting soil is a 1:2 mixture of humus and undisturbed soil, with a thickness strictly controlled at 600mm. Backfill in layers (each layer 200mm thick), compacting with a small plate vibratory compactor, and then manually raking the surface. After backfilling, construct a water-retaining embankment along the inner edge of the terrace to prevent rainwater erosion.

10. A construction method for a landscape terrace structure with a wire mesh sprayed layer as described in any one of claims 1 to 9, characterized in that, Includes the following steps: S1, stepped excavation; the original slope is excavated in stages and sections to form multi-level terraced fields with a stepped structure. S2, Construct a retaining wall; Construct a retaining wall that slopes backward on the open front edge of the terrace as the main support structure of the terrace; During the construction process, embed a steel hook at predetermined intervals along the vertical and horizontal directions of the retaining wall, so that one end of the steel hook is inserted into the wall body of the retaining wall for anchoring, and the other end is exposed on the wall surface of the retaining wall and used for subsequent wire mesh connection. S3, Cover with wire mesh; After the retaining wall is built, wire mesh is fully laid on the outer surface of the retaining wall. The wire mesh is fixed to the steel bar hooks by binding or welding, forming a stable reinforced skeleton layer on the outer surface of the retaining wall. S4, Sprayed Mixture: The mixture is evenly sprayed onto the outer surface of the retaining wall that has been wire meshed using spraying equipment, so that the mixture completely covers the reinforced skeleton layer and forms a wire mesh sprayed mixture layer. S5, Backfill with planting soil; After the mixture has initially set, backfill with planting soil on the base of the terrace. The planting soil is compacted in layers to form a planting soil layer for planting crops.
