Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a large-area steep slope anti-slip permeable planting roof system. Background Technology

[0002] With the deepening development of low-carbon and green urban concepts, green roofs, as a new type of building that integrates ecology, environmental protection, and aesthetics, are gradually becoming an important part of modern urban architecture. As a typical representative of green building, green pitched roofs not only enhance the aesthetics and ecological nature of buildings but also effectively improve the urban environment, increase urban green space, improve the microclimate, and enhance the aesthetic value of buildings. They are widely used in the construction of public buildings such as exhibition halls, museums, and urban park slopes. Large-area steep slope anti-slip permeable green roof systems feature high permeability, anti-slip properties, heat insulation, waterproofing, energy saving, and emission reduction. They also achieve effects such as increasing green space, saving water resources, improving the ecological environment, and purifying the air.

[0003] Traditional methods of planting vegetation on steep slopes have drawbacks such as easy soil slippage and poor water permeability.

[0004] A permeable concrete buttress retaining wall structure is disclosed in Chinese patent document CN212052857U. This structure mainly consists of reinforced concrete wall panels, permeable concrete wall panels, wall bases, wall toe slabs, buttresses, drainage ditches, and vegetation. The drainage ditch is composed of wall toe slabs, water-retaining panels, and wall panels. Crushed stones are placed inside the drainage ditch, and planting soil is backfilled on top for planting vegetation. This permeable buttress retaining wall retains the original lightweight nature, is simple to construct, and fully utilizes the soil on the wall bases to resist overturning and sliding. Simultaneously, the placement of crushed stones and vegetation in the drainage ditch further increases the retaining wall's anti-sliding and anti-overturning capabilities. By using permeable concrete to transition from point drainage to surface drainage, and forming a drainage system with the collection ditch, groundwater can be quickly discharged, avoiding the problem of water collection caused by traditional separate drainage ditches. It is particularly suitable for areas with abundant surface water and frequent rainfall. Green plants can be placed on the drainage ditch to meet the requirements of modern green building structures. However, the soil layer of this permeable concrete buttress retaining wall structure is not treated, and the soil layer is not suitable for planting vegetation.

[0005] To address the shortcomings of the existing technologies, providing a large-area, steep-slope, anti-slip, permeable planting roof system is a worthwhile research topic. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of planting soil, such as easy slippage and poor permeability, and to provide a large-area steep slope anti-slip permeable planting roof system, which achieves the technical effect suitable for planting.

[0007] The objective of this utility model is achieved through the following technical solution: A large-area steep slope anti-slip permeable planting roof system includes a reinforced concrete roof panel, and above the reinforced concrete roof panel, from bottom to top, an insulation layer, a cement mortar leveling layer, a coating waterproof layer, a roll waterproof layer, a root penetration resistant waterproof layer, a fiber-reinforced lime mortar isolation layer, a fine stone concrete rigid protective layer, a drainage board, and a green planting layer. It also includes an anti-slip system set in each soil layer, and a permeable system connected to the drainage board.

[0008] The anti-slip system includes anti-slip steel bars running through each layer, tie strips fixedly connected to the anti-slip steel bars, retaining boards set in the green planting layer, and anti-slip grids fixedly connected between the retaining boards. The multi-level synergistic effect enhances the stability, durability, and ecological function of the planted roof on steep slopes.

[0009] The anti-slip steel bars, tie strips, retaining plates, and anti-slip grids are welded together. The retaining plates are evenly distributed on the green planting layer, and the anti-slip grids are set between the retaining plates.

[0010] The retaining plate is an L-shaped stainless steel plate, and the distance between adjacent retaining plates is 1200mm.

[0011] The connecting strip is made of flat steel, and the vertical spacing of the connecting strip is 800mm. The connecting strip is fully welded to the anti-slip steel bar to ensure anchoring force and form a stable anti-slip system for the planting soil.

[0012] The permeable system includes a non-woven polyester fiber cloth covering the surface of the hydrophobic board, a buffer zone set below the green planting layer, a sponge city pebble permeable layer set underground in the city, and a drainage pipe connecting the buffer zone and the sponge city pebble permeable layer. It solves the technical pain points of traditional permeable structures such as easy clogging, low drainage efficiency and weak ecological function, and provides a sustainable solution for the construction of sponge cities.

[0013] The permeable system also includes pebble anti-slip grooves set on both sides of the buffer zone, inner and outer eaves of the anti-slip grooves set on both sides of the pebble anti-slip grooves, and galvanized exhaust risers that run through each layer. The top of the galvanized exhaust riser is connected to the outside air.

[0014] The buffer strip is made of pebbles, and the hydrophobic plate is made of polyethylene hydrophobic plate, with water guiding grooves opened on the hydrophobic plate.

[0015] The drainage pipe is made of PVC, with a diameter of ≥100mm and a slope of ≥3%. It features strong water permeability, anti-slip properties, heat insulation, waterproofing, energy saving, and emission reduction.

[0016] 1. This large-area steep slope anti-slip permeable planting roof system has the characteristics of strong permeability, anti-slip, heat preservation, heat insulation, waterproofing, energy saving and emission reduction. At the same time, it can also increase green area, save water resources, improve the ecological environment and purify the air. It has the advantages of simple construction and operation, long service life and low maintenance cost. It is technologically advanced and has significant social and economic benefits.

[0017] 2. This large-area, steep-slope, anti-slip, permeable planting roof system utilizes the capillary structure between the fibers of the non-woven polyester fabric to absorb 2.5 times its own weight in water, which is slowly released during dry periods, increasing the soil moisture content and improving the roof system's water storage capacity in arid environments. Through the functional coupling of filtration, water retention, and drainage, the system achieves improved efficiency and ecological upgrades, solving the technical pain points of traditional permeable structures such as easy clogging, low drainage efficiency, and weak ecological functions, and providing a sustainable solution for sponge city construction.

Detailed Implementation

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0020] like Figures 1 to 2As shown, a large-area steep slope anti-slip permeable planting roof system includes a reinforced concrete roof panel 01, and above the reinforced concrete roof panel 01, from bottom to top, an insulation layer 02, a cement mortar leveling layer 03, a waterproof coating layer 04, a rolled waterproof layer 05, a root-penetration resistant waterproof layer 06, a fiber-reinforced lime mortar isolation layer 07, a fine stone concrete rigid protective layer 08, a drainage board 09, and a green planting layer 22. It also includes an anti-slip system set in each soil layer, and a permeable system connected to the drainage board 09.

[0021] like Figures 1 to 2 As shown, the anti-slip system includes anti-slip steel bars 11 that run through each layer, tie strips 12 that are fixedly connected to the anti-slip steel bars 11, retaining boards 13 set in the green planting layer 22, and anti-slip grids 14 that are fixedly connected between the retaining boards 13. By integrating anti-slip steel bars, tie strips, retaining boards and anti-slip grids into the green roof, the multi-level synergistic effect can improve the stability, durability and ecological function of the green roof on steep slopes.

[0022] like Figures 1 to 2 As shown, the anti-slip steel bars 11, tie strips 12, retaining plates 13, and anti-slip grids 14 are welded together. The retaining plates 13 are evenly distributed on the green planting layer 22, and the anti-slip grids 14 are set between the retaining plates 13. The retaining plates 13 can resist water erosion, and together with the planting layer, the amount of soil and water loss is greatly reduced. The textured surface treatment of the anti-slip grids 14 makes the friction coefficient reach 0.85. After being combined with the retaining plates, the overall anti-slip force can be increased by 40%. The retaining plates provide high-strength support (yield strength ≥250MPa), and the anti-slip grids enhance the shear performance (shear strength ≥120MPa), forming a structure that combines rigidity and flexibility, which greatly improves the anti-slip performance of the system. Furthermore, the aluminum alloy retaining plate has a porosity of >65%, providing growth space for plant roots. Combined with the drainage channels of the anti-slip grid, it improves the soil's water retention performance, increasing the root penetration rate of herbaceous plants by 45%. This allows the waterproof structure to work in conjunction with the plant roots to form a stable composite protective layer.

[0023] like Figure 1 As shown, the retaining plate 13 is an L-shaped stainless steel plate, and the spacing between adjacent retaining plates 13 is 1200mm. The L-shaped retaining plate 13 forms a stable triangular structure, which further improves the impact resistance of the retaining plate 13. In addition, the horizontal section of the L-shaped retaining plate 13 generates frictional interlocking force with the soil surface, and with the vertical section anchoring, the anti-sliding safety factor reaches 1.7.

[0024] like Figure 2As shown, the tensioning strip 12 is made of flat steel, and the vertical spacing of the tensioning strip 12 is 800mm. The tensioning strip 12 is fully welded to the anti-slip steel bar 11. The flat steel tensioning strip 12 and the retaining plate 13 form a grid skeleton. The anti-slip grid 14 can divide the planting soil and form a triple constraint to prevent slippage. The pre-embedded depth of the anti-slip steel bar 11 is ≥200mm, which can ensure the anchoring force and form a stable anti-slip system for the planting soil. Example 2

[0025] like Figure 1 As shown, the permeable system includes a non-woven polyester fiber cloth 10 covering the surface of the drainage board 09, a buffer strip 18 set below the green planting layer 22, a sponge city pebble permeable layer 20 set underground in the city, and a drainage pipe 19 connecting the buffer strip 18 and the sponge city pebble permeable layer 20. By setting the non-woven polyester fiber cloth 10 on the surface of the drainage board 09 and controlling the pore size of the non-woven polyester fiber cloth 10 to 0.2-0.5mm, it can intercept 95% of soil particles (particle size > 0.3mm) and prevent the drainage board 09 from being blocked. The blockage allows the permeable board 09 to maintain normal water conveyance for a long time, and the capillary structure between the fibers of the non-woven polyester fiber cloth 10 can absorb 2.5 times its own weight in water, which is slowly released during the dry season, increasing the water content of the soil layer and improving the water storage capacity of the roof system in arid environments. Through the functional coupling of filtration, water retention and drainage, the efficiency of the permeable system is improved and the ecology is upgraded. This solves the technical pain points of traditional permeable structures such as easy blockage, low drainage efficiency and weak ecological function, and provides a sustainable solution for the construction of sponge cities. Example 3

[0026] like Figure 2 As shown, the permeable system also includes pebble anti-slip grooves 17 set on both sides of the buffer zone 18, anti-slip groove inner eaves 15 and anti-slip groove outer eaves 16 set on both sides of the pebble anti-slip grooves 17, and galvanized exhaust risers 21 penetrating each layer. The top of the galvanized exhaust riser 21 is connected to the outside air.

[0027] The buffer strip 18 is made of pebbles, and the drainage board 09 is made of polyethylene drainage board. Water guide grooves are opened on the drainage board 09. The thickness of the pebble buffer strip 18 is ≥150mm, which can filter mud and sand and prevent drainage pipe from being blocked. Furthermore, the hydrophobic plate 09 has a water conductivity ≥1.5L / (m·s), the pebble buffer zone 18 has a pebble particle size of 20-40mm, the pebble particle size of 20-40mm has moderate gaps (porosity of about 30%-40%), which can intercept mud and sand (particle size ≤2mm) while allowing water to flow through, thus avoiding blockage of the drain pipe 19.

[0028] Drainage pipe 19 is made of PVC with a diameter ≥100mm and a slope ≥3%. This roofing system features strong water permeability, anti-slip properties, heat insulation, waterproofing, energy saving, and emission reduction. It can also increase green area, save water resources, improve the ecological environment, and purify the air. It has the advantages of simple construction, long service life, and low maintenance cost. It is technologically advanced and has significant social and economic benefits.

[0029] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
