Description

[Technical Field]

[0001] The present invention relates to a method for producing a water-permeable garden. [Background technology]

[0002] In recent years, rooftop gardens and green spaces have been attracting attention, but using pebbles on the rooftop can lead to them being blown away by the wind, so rooftop gardens and the like are often designed to avoid using pebbles as much as possible. In addition, rooftop gardens and the like must also take into consideration the drainage of rainwater, and from the perspective of drainage as well, they are often designed to avoid the use of pebbles and other materials.

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-186557 Summary of the Invention [Problem to be solved by the invention]

[0004] On the other hand, there is a demand for rooftop gardens to be built in the so-called "karesansui" style of Japanese gardens, which are gardens that do not use any water at all, but instead use only sand and stones to express the scenery of mountains and water. However, as mentioned above, it is difficult to create a dry landscape garden on a rooftop due to wind and drainage considerations.

[0005] Furthermore, not just in rooftop gardens, but in all dry landscape gardens, the patterns tend to become distorted over time due to wind, rain, and natural falling of plants, and they have to be recreated each time, making maintenance a lot of work.

[0006] Therefore, an object of the present invention is to provide a method for manufacturing a water-permeable Japanese garden that prevents the stone pattern from collapsing.

[0007] Patent Document 1 describes a grating that is made permeable by solidifying aggregate such as stone with an adhesive. The technology of solidifying aggregate with an adhesive to make it permeable is well known from Patent Document 1 and other documents, but Patent Document 1 does not describe how to form a pattern on the aggregate. [Means for solving the problem]

[0008] In order to solve the above problems, the present invention has the following features. The present invention is a method for manufacturing a water-permeable garden, which includes the steps of mixing aggregate and binder, spreading the aggregate mixed with the binder evenly, forming grooves at predetermined intervals in the spread aggregate, raising the aggregate between adjacent grooves to form mounds, hardening the binder until it has a predetermined viscosity, shaping the aggregate after the binder has hardened to the predetermined viscosity, and completely hardening the binder.

[0009] The present invention also provides a method for manufacturing a permeable garden, which includes the steps of mixing aggregate with a binder, spreading the aggregate mixed with the binder evenly, forming grooves at predetermined intervals in the spread aggregate, hardening the binder until it has a predetermined viscosity, shaping the aggregate after the binder has hardened to the predetermined viscosity, and completely hardening the binder.

[0010] The present invention also provides a method for manufacturing a water-permeable garden, which includes the steps of spreading aggregate evenly, forming grooves at predetermined intervals in the spread aggregate, pouring a binder mixed with a solvent over the aggregate, hardening the binder until it has a predetermined viscosity, shaping the aggregate after the binder has hardened to the predetermined viscosity, and completely hardening the binder.

[0011] When working over a wide area, it is preferable to repeat the process of shaping the aggregate into a mountain shape for each work area that the worker can work in. [Effects of the Invention]

[0012] According to the present invention, the aggregates are bonded with a binder and have numerous voids, so a water-permeable Japanese garden is provided in which the stone pattern does not collapse.

[0013] These and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. [Brief explanation of the drawings]

[0015] The process for creating a Japanese garden according to this embodiment will be described with reference to FIG. First, aggregate is mixed with a binder (adhesive) (S101). The aggregate used is preferably gravel made from natural stone, but is not limited thereto and may also be glass chips, crushed stone, or the like. The particle size of the aggregate is not limited, but may be, for example, 40 mm to 3 mm.

[0016] The adhesive to be mixed with the aggregate is preferably, but not limited to, a urethane resin binder mixed with ceramic fiber or glass fiber (such as Fiber U manufactured by Fine Kogyo Co., Ltd. (2-27-6 Higashibeppu, Settsu City, Osaka Prefecture)). For example, an epoxy resin binder mixed with ceramic fiber or glass fiber may also be used. The fibers should be about 1 mm to 0.3 mm in diameter, but are not limited to this. Furthermore, fibers do not have to be mixed into the binder (adhesive).

[0017] For example, 5% by weight of binder is mixed with the aggregate. The mixing ratio is an example. It is sufficient to mix about 3 to 8% by weight of binder relative to the weight of aggregate. If there is too much binder, it will drip and harden at the bottom, reducing permeability, so care must be taken. If there is too little binder, there is a risk of the aggregates collapsing, so care must be taken. The binder is mixed with the aggregate so that it is mixed uniformly.

[0018] Next, aggregate mixed with binder is placed in the work area (see FIG. 4) and spread evenly (S102). Here, the work area refers to the area in which a worker can work.

[0019] Next, grooves are formed at predetermined intervals in the spread aggregate using a tool such as that shown in Figure 3 (S103). The worker holds the handle 3 and inserts the groove projections 4 into the spread aggregate to form grooves resembling the flow of a river.

[0020] Next, as shown in Figure 2(a), the aggregate between the grooves is piled up to form a mountain-like shape (S104). Examples of the mountain-like piled up state are shown in Figures 5 and 6. At this stage, the binder has not yet hardened, and as time passes, some of the piled up aggregate will sag.

[0021] Next, the binder is hardened until the aggregate has a predetermined viscosity (S105). The predetermined viscosity is a viscosity that allows the aggregate to be piled up into a mountain shape and that prevents the piled up aggregate from dripping under its own weight. The time it takes to reach the predetermined viscosity varies greatly depending on the temperature and humidity. The hardening time to reach the predetermined viscosity may be controlled by the temperature and humidity, rather than based on empirical values. Alternatively, the control method may involve determining how many hours to wait in summer and how many hours to wait in winter.

[0022] Once the binder has hardened to the required viscosity, the workers shape the aggregate into a mountain-like shape to form a beautiful mountain (S106). The mountain-like pattern created in this state will ultimately become the pattern of the dry landscape garden, so the workers must proceed carefully to express the natural flow of a river.

[0023] Since the worker's reach is limited, once the shaping of the aggregate in one work area is completed, steps S102 to S107 are carried out for the next work area, and this process is repeated to work on a wide area.

[0024] Figure 2 shows an example. When work is completed in one work area (Figure 2(a)), mountain-shaped mounding work is carried out in the adjacent work area so that the river flows together (Figure 2(b)). Then, mountain-shaped mounding work is carried out in the work area in front of it (Figure 2(c)). Furthermore, mountain-shaped mounding work is carried out in the work area next to that (Figure 2(d)), so that mountain-shaped mounding work is carried out over a wide area.

[0025] Once construction is complete in all work areas, the process waits for the concrete to harden completely (S108), and the dry landscape Japanese garden is complete (S109).

[0026] The completed Japanese garden will look like Figure 7. The aggregates are bonded together with a binder at adhesive points 1, so the mountain-shaped aggregates will not collapse due to wind or rain, and will not fall off naturally.

[0027] As shown in FIG. 8, the aggregates are bonded together by the binder, but there are many voids 2 between them. Therefore, rainwater flows downward through the gap. As a result, the pattern made of the aggregate produced in this embodiment does not collapse and has water permeability. As a result of the above, a permeable Japanese garden was created that would prevent the stone patterns from collapsing.

[0028] (Variation) In the above embodiment, after forming grooves at predetermined intervals in S103, the aggregate between the grooves is temporarily formed into a mountain shape (S104). However, without performing this temporary mountain shape step, after forming the grooves, the aggregate may be shaped into a mountain shape when it has hardened to a predetermined viscosity (S106).

[0029] (Other embodiments) Alternatively, a method may be used in which a solvent is mixed with the binder to make it highly fluid, and the mixed binder is poured over the aggregate to form a mountain-like aggregate. The process is illustrated in Fig. 9. In Fig. 9, the same steps as those in Fig. 1 are denoted by the same reference numerals, and the description thereof will be omitted.

[0030] 9, first, a binder and a solvent are mixed to produce a binder with high fluidity (S201). The mixing ratio is not particularly limited. For example, a weight ratio of 1:1 is preferable.

[0031] Next, aggregate without any binder mixed in is spread evenly in the work area (S102), grooves are formed at predetermined intervals (S103), and the spaces between the grooves are made into a mountain shape (S104: this step is optional), and a highly fluid binder mixed with a solvent is poured onto the aggregate from above (S205).

[0032] Then, when the aggregate has hardened to a certain degree of viscosity, it is shaped into a mountain-like shape (S206).

[0033] In this alternative embodiment, after the solvent evaporates, the binder bonds the aggregate together to produce a permeable mound-shaped garden.

[0034] Although the present invention has been described in detail above, the above description is merely illustrative of the present invention in all respects and is not intended to limit its scope. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention. Each of the constituent elements of the invention disclosed in this specification is considered to be an independent, stand-alone invention. Inventions that combine the constituent elements in any manner are also included in the present invention. The specific expressions in this specification are merely examples, and the present invention also includes those that conceptualize these exemplary expressions. [Industrial Applicability]
