Description

Technical Field

[0001] This utility model relates to a rain garden system, specifically a structure of a ground rain garden system integrating large-size rain chain drainage. Background Technology

[0002] Traditional rain gardens rely on surface runoff or perforated pipes for drainage. During heavy rain, the system is prone to failure due to water overflow. Therefore, rain chains are now used as the drainage system. Traditional rain chains are mostly used as building facade decorations, and their drainage path is independent of the rain garden structure. This means that rainwater cannot directly enter the garden planting layer, and additional surface drainage ditches or perforated pipes are required, which increases the construction complexity and material costs.

[0003] Secondly, most existing rain chains adopt an open-link structure. When heavy rain is accompanied by strong winds, the water flow is easily blown away, causing rainwater to splash and deviate from the collection area, reducing drainage efficiency and affecting the surrounding environment. Utility Model Content

[0004] The purpose of this invention is to provide a structure for a ground-level rain garden system that integrates large-size rain chain drainage, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a structure for a ground rain garden system integrating a large-size rain chain drainage, comprising: a canopy installed on a wall, the end of which is provided with a water collection trough; a landscape floor, located on the outside of the wall; and a rain chain connecting the drainage holes formed on the water collection trough and the landscape floor, comprising multiple stainless steel pipes and connectors connecting adjacent stainless steel pipes, wherein a drainage channel is formed on the inner side of the stainless steel pipes.

[0006] The structure of the integrated large-size rain chain drainage ground rain garden system as described above is as follows: a ring is fixed inside the end of the stainless steel pipe facing the landscape ground, and a second connecting buckle is formed inside the ring; a first connecting buckle is formed inside the end of the stainless steel pipe away from the landscape ground, and the two ends of the connector are connected to the first connecting buckle and the second connecting buckle.

[0007] The structure of the integrated large-size rain chain drainage ground rain garden system as described above: the connector includes a connecting rope and two buckles fixed at both ends of the connecting rope and respectively connected to the first connecting buckle and the second connecting buckle.

[0008] The structure of the integrated large-size rain chain drainage ground rain garden system as described above: a connector for connecting a stainless steel pipe is installed at the drain hole on the water collection trough, and a gap is formed between the connector and the drain hole for water to flow into the stainless steel pipe.

[0009] The structure of the integrated large-size rain chain drainage ground rain garden system as described above: a prefabricated root barrier is formed on the landscape surface, the prefabricated root barrier includes a concrete base layer embedded in the landscape surface and a gravel layer laid on the concrete base layer; the concrete base layer is equipped with connection positions for connecting connectors.

[0010] The structure of the integrated large-size rain chain drainage ground rain garden system described above: a support beam is also fixed to the outside of the wall, and the canopy and water collection trough are installed on the support beam.

[0011] The structure of the integrated large-size rain chain drainage ground rain garden system as described above: the landscape ground includes, from top to bottom, a vegetation layer, a planting soil layer, a gravel layer, a geotextile, a textured drainage board layer, a flexible protective layer, a root-penetration resistant waterproof layer, a general waterproof layer, a leveling layer, a thermal insulation layer, a vapor barrier layer, and a concrete structural layer.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: Rainwater flows into the collection trough along the canopy, and the water in the collection trough falls directionally onto the landscape ground through the rain chain, achieving directional discharge of rainwater. Simultaneously, the rain chain uses stainless steel pipes and connectors, allowing rainwater to flow along the interior of the stainless steel pipes. With the help of the connectors between adjacent stainless steel pipes, rainwater flows along the connectors into the next stainless steel pipe, improving the wind resistance of the rain chain and eliminating the problem of water droplets not concentrating due to wind detachment during heavy rain. The circular rings reduce the size of the drainage outlet at the bottom of the stainless steel pipe, thus acting as a confluence for rainwater, allowing rainwater falling from the stainless steel pipe to flow smoothly into the next stainless steel pipe along the connectors, significantly reducing the splashing range. At the same time, the circular rings lower the center of gravity of the stainless steel pipe, making the bottom weight greater than the top weight, which to some extent reduces the amplitude of wind swaying and eliminates noise generated when the stainless steel pipe sways and contacts the connectors.

Detailed Implementation

[0017] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0018] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0019] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0020] Please see Figures 1-3 In this embodiment of the present invention, a ground rain garden system integrating a large-size rain chain drainage system is constructed, comprising: a canopy 3 installed on a wall 1, with a water collection trough 4 at the end of the canopy 3, wherein a support beam 2 is fixed on the outer side of the wall 1, and the canopy 3 and the water collection trough 4 are installed on the support beam 2; a landscape floor 7, disposed on the outer side of the wall 1; and a rain chain 6 connecting the drainage holes formed on the water collection trough 4 and the landscape floor 7, comprising a plurality of stainless steel pipes 601 and a connector 602 connecting two adjacent stainless steel pipes 601, wherein a drainage channel is formed on the inner side of the stainless steel pipes 601.

[0021] The awning 3 is fixed to the outside of the wall 1 and located at the lower end of the window 101 on the wall 1. The window 101 is equipped with louvers 102. The awning 3 can prevent rainwater from entering the window 101 on rainy days and can also direct the rainwater to drain. The awning 3 is set at an angle.

[0022] In this embodiment, rainwater flows from the canopy 3 into the water collection trough 4. The water in the water collection trough 4 falls directionally onto the landscape ground 7 through the rain chain 6, achieving directional discharge of rainwater. At the same time, the rain chain 6 is set with stainless steel pipes 601 and connectors 602, which allows rainwater to flow along the inside of the stainless steel pipes 601. Under the action of the connectors 602 between two adjacent stainless steel pipes 601, the rainwater enters the next stainless steel pipe 601 along the connectors 602, improving the wind resistance of the rain chain 6 and eliminating the problem of water droplets not concentrating due to water flow leaving the rain chain 6 under the action of wind during heavy rain.

[0023] It should also be noted that the spacing between two adjacent stainless steel pipes 601 is relatively small, which makes the rain chain 6 form a nearly closed water guiding channel, while also satisfying the flexibility of the rain chain 6.

[0024] Further, please refer to Figure 2 and Figure 3 A ring 604 is fixed inside the end of the stainless steel pipe 601 facing the landscape ground 7, and a second connecting buckle 605 is formed inside the ring 604; a first connecting buckle 603 is formed inside the end of the stainless steel pipe 601 away from the landscape ground 7, and the two ends of the connector 602 are connected to the first connecting buckle 603 and the second connecting buckle 605.

[0025] The circular ring 604 reduces the size of the drain outlet below the stainless steel pipe 601, thus converging rainwater and allowing it to flow smoothly from the stainless steel pipe 601 into the next stainless steel pipe 601 via the connector 602, significantly reducing the splashing range. Simultaneously, the circular ring 604 lowers the center of gravity of the stainless steel pipe 601, making the bottom weight greater than the top weight, which reduces the swaying amplitude of the stainless steel pipe 601 in the wind and eliminates noise generated when the stainless steel pipe 601 sways and contacts the connector 602.

[0026] Further, please refer to Figure 2 and Figure 3 The connector 602 includes a connecting rope 6021 and two buckles 6022 fixed at both ends of the connecting rope 6021 and respectively connected to the first connecting buckle 603 and the second connecting buckle 605. The connecting rope 6021 is made of stainless steel, which increases the service life of the connecting rope 6021 to a certain extent.

[0027] The latch 6022 is a movable latch, similar to an existing elastic hook. It only needs to be connected to the first connecting latch 603 and the second connecting latch 605. This embodiment will not elaborate further on this.

[0028] Please see Figure 1A connector 5 for connecting a stainless steel pipe 601 is installed at the drain hole on the water collection tank 4. A gap is formed between the connector 5 and the drain hole to allow water to flow into the stainless steel pipe 601. The connector 5 is mainly used to connect and fix the stainless steel pipe 601. The bottom of the connector 5 is tapered and inserted into the stainless steel pipe 601. Rainwater entering the stainless steel pipe 601 along the gap can be guided by the tapered structure to collect inside the stainless steel pipe 601.

[0029] Furthermore, a prefabricated root barrier is formed on the landscape ground 7. The prefabricated root barrier includes a concrete base layer 9 embedded in the landscape ground 7 and a gravel layer 8 laid on the concrete base layer 9. A connection position for connecting the connector 602 is installed on the concrete base layer 9.

[0030] The crushed stone layer 8 can reduce the impact of rainwater on the concrete base layer 9 to a certain extent, and at the same time achieve the function of rainwater dispersion. After entering the crushed stone layer 8, the rainwater can spread and flow to the surrounding area to enter the landscape ground 7.

[0031] In one embodiment, the landscape ground 7 comprises, from top to bottom, a vegetation layer 701, a planting soil layer 702, a gravel layer 703, a geotextile 704, a textured drainage board layer 705, a flexible protective layer 706, a root-penetration resistant waterproof layer 707, a general waterproof layer 708, a leveling layer 709, a thermal insulation layer 710, a vapor barrier layer 711, and a concrete structure layer 712.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
