Description

Technical Field

[0001] This utility model relates to the field of greening and planting technology for terrace gardens, and in particular to a topographic landscaping structure for planting and greening in terrace gardens. Background Technology

[0002] As we all know, various terrace gardens and rooftop gardens, due to limitations such as floor load-bearing capacity and drainage, cannot achieve the natural effect of planting on slopes like ground-level gardens. They can only use the single method of building flower beds for planting, resulting in a stiff and rigid planting effect.

[0003] The biggest problem facing terrace greening is the load-bearing capacity of the floor slab. Floor slabs usually have limited load-bearing capacity. If you want to create an undulating slope shape on the floor, you must cover it with a thick layer of planting soil. After the planting soil is wet, the weight per cubic meter will far exceed the floor's load-bearing standard, which will cause serious safety hazards. Therefore, it is quite difficult to create a slope-shaped greening on a terrace. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, one of the objectives of this utility model is to provide a topographic landscaping structure for planting greenery in terrace gardens.

[0005] One of the objectives of this utility model is achieved through the following technical solution: a topographic landscaping structure for planting greenery in a terrace garden, comprising a parapet wall, a floor slab, supporting columns, a stainless steel plate, geogrids, planting soil, and ground cover greening. Supporting columns are installed above the floor slab, with a stainless steel plate fixedly connected to the top of each column. Geogrids are installed above the stainless steel plate, and planting soil is laid on top of the geogrids. Ground cover greening is planted on the surface of the planting soil. The stainless steel plate is welded to form a sloping area and a sunken planting pit. Drainage holes are provided at the lower part of the sloping area. A ceramsite drainage layer is provided inside the sunken planting pit. Drainage holes are pre-embedded at the location of the sunken planting pit, and drainage pipes are pre-embedded below the ceramsite drainage layer. The supporting columns adopt an adjustable-height telescopic steel structure, comprising an inner pipe and an outer pipe. The inner pipe is sleeved inside the outer pipe, and height adjustment bolts are provided on the side wall of the outer pipe.

[0006] Furthermore, the inner wall of the stainless steel plate is provided with triangular reinforcing ribs; a non-woven fabric isolation layer is provided between the hydrophobic layer of the ceramsite and the planting soil.

[0007] Furthermore, anti-slip textures are provided between the inner and outer tubes of the telescopic steel structure.

[0008] Furthermore, the number of the triangular reinforcing ribs is no less than three, and they are evenly distributed on the inner sidewall of the stainless steel plate.

[0009] Furthermore, the edge of the nonwoven fabric isolation layer is fixedly connected to the stainless steel plate by welding.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This structure can solve the load-bearing problem faced by planting terrain landscaping in terrace gardens and rooftop gardens. Through a special structure, it can achieve a natural planting effect similar to the undulating and sloping terrain of ground gardens. With adjustable height support columns, the slope height can be flexibly adjusted according to design requirements, which improves the flexibility and adaptability of terrain landscaping.

[0012] The triangular reinforcing ribs on the inner side of the stainless steel plate effectively enhance the structural strength, avoid the deformation of the stainless steel plate due to load, and improve the stability of the entire terrain landscaping structure.

[0013] The non-woven fabric isolation layer prevents the planting soil from seeping into the expanded clay aggregate drainage layer, ensuring drainage and preventing soil loss, thus improving the effect of greening.

[0014] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.

[0020] Please see Figure 1 This embodiment of the topographic landscaping structure for planting greenery in a terrace garden includes a parapet wall 1, a floor slab 2, supporting columns 3, a stainless steel plate 4, a geogrid 5, planting soil 6, and ground cover 7. Supporting columns 3 are installed above the floor slab 2, with the stainless steel plate 4 fixedly connected to the top of the supporting columns 3. Geogrid 5 is installed above the stainless steel plate 4, and planting soil 6 is laid on top of the geogrid 5. Ground cover 7 is planted on the surface of the planting soil 6. The stainless steel plate 4 is welded to form a sloped area and a sunken planting pit 9. Drainage holes 8 are provided at the lower part of the sloped area. A ceramsite drainage layer 10 is installed inside the sunken planting pit 9. The location of the sunken planting pit 9 is predetermined. Drainage holes 11 are buried, and drainage pipes 12 are pre-buried below the expanded clay drainage layer 10. The support column 3 adopts an adjustable height telescopic steel structure, including an inner pipe and an outer pipe. The inner pipe is sleeved inside the outer pipe, and height adjustment bolts are provided on the side wall of the outer pipe. Triangular reinforcing ribs 13 are provided on the inner side wall of the stainless steel plate 4. A non-woven fabric isolation layer 14 is provided between the expanded clay drainage layer 10 and the planting soil 6. Anti-slip textures are provided between the inner and outer pipes of the telescopic steel structure. There are no less than 3 triangular reinforcing ribs 13, which are evenly distributed on the inner side wall of the stainless steel plate 4. The edge of the non-woven fabric isolation layer 14 is fixedly connected to the stainless steel plate 4 by welding.

[0021] Working principle: First, we waterproof the parapet wall 1 and floor slab 2 where the landscaping construction will take place. Then, we determine the slope position and elevation, as well as the location of the planting tree pits, according to the needs of the planting. Next, we install the support columns 3 as needed. The support columns can be made of steel or brick.

[0022] After completing the above work, we located the low point of the slope and the sunken planting tree pit 9 according to the needs of greening drainage, and pre-buried the main drainage pipe 12 for greening.

[0023] After pre-installing the drainage pipes, we cut and weld stainless steel plates 4 according to the design requirements, and weld the sloping area and sunken planting pits 9 using the stainless steel plates. During the construction, we should pay attention to reserving drainage holes 8 in the lower part of the slope and pre-installing drainage holes 11 at the location of the sunken planting pits.

[0024] This completes the basic design. After completing the basic design, we proceed with the planting soil filling. When filling the planting soil in the sloping area, we first install geogrids 6 on the stainless steel plate to fix the planting soil 7. After the geogrids 6 are installed, the planting soil 6 can be filled. Before filling the sunken planting pit 9 with planting soil, a layer of expanded clay granules 10 should be laid first, followed by non-woven fabric, before the planting soil can be filled into the tree pit.

[0025] After the planting soil is filled in, the ground cover 7 and the sunken planting tree pits 9 can be planted. In this way, the entire naturally undulating slope planting terrain is completed, with natural slope undulation and excellent greening effect.

[0026] The drainage holes at the lower slope and those in the sunken tree pit are connected to the main drainage pipe via PVC drainage pipes. During rainfall, water seeps through the planting soil into the geogrid, flows along the stainless steel slab slope into the drainage holes, and is quickly discharged through a drainage slope of ≥3%. The expanded clay aggregate drainage layer (15-20cm thick) utilizes the 20% porosity between the expanded clay aggregates to allow accumulated water to drain through the drainage holes within 0.5 hours, preventing the weight of accumulated water from increasing the floor load.

[0027] The non-woven fabric isolation layer's soil-retention and water-repellent functions: 200g / ㎡ of non-woven fabric is laid between the expanded clay aggregate drainage layer and the planting soil. The fiber pores (5-10μm) allow water to pass through while blocking planting soil particles with a diameter >0.1mm, preventing the expanded clay aggregate layer from becoming clogged. Experimental data shows that after using the non-woven fabric, the drainage efficiency of the expanded clay aggregate layer still maintains 90% of its initial value after 12 months.

[0028] HDPE geogrids (5cm x 5cm grid size) are fixed to stainless steel plates with expansion bolts. After planting soil is filled into the grid, a soil-grid interlocking structure is formed. Shear tests show that the geogrid can increase the anti-slip coefficient of the planting soil from 0.3 to 0.6, preventing landslides in sloping areas. For example, on a 25° slope, the critical angle for soil slippage without geogrids is 18°, which increases to 35° after using geogrids.

[0029] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
