Description

   The present invention relates to a container having an advantageous effect in use in a tropical climate and a rooftop greening system using the container.

  Cities are often referred to as heat islands. In urban areas, buildings are planted and the ground is artificially created, so there is usually little space for planting plants, and temperatures are usually higher than in the surrounding rural areas. Such a surface absorbs and stores heat before radiating it to the surroundings, which causes a phenomenon known as the “urban heat island effect”.

  With the expansion of economic and land development, many cities no longer have enough space to plant green on the ground. To alleviate the urban heat island phenomenon, alternative spaces for planting must be found.

  Rooftop gardens are one way to create new spaces for planting plants in densely populated urban areas to improve the living environment. As a result, it is possible to add color to urban landscapes and plant trees without using space that is extremely limited in densely populated cities.

  The current standard rooftop greening system consists of a waterproof membrane, roof protection, moisture retaining layer, drainage layer, growth medium layer, and vegetative layer on the roof. Become. These layers are usually installed in the field. The operator must install these components one by one on the roof.

  A different system has been adopted for the roofs of public houses in Singapore. On top of the concrete roof body, an auxiliary roof is used as a barrier to heat, thereby minimizing the heat absorbed by the roof body and reducing the heat transferred to the living part directly below it. The auxiliary roof system is constituted by a plurality of ferrocement roof planks installed on a concrete stool, and a gap is provided between the planks and the roof body. On high-temperature days, the surface temperature of the ferrocement roof plank may exceed 60 ° C. The air in the air gap functions as a heat insulating material, and heat conduction to the roof body can be minimized. Although the auxiliary roof system is effective in insulating the top floor dwelling, the light and heat emitted by the ferrocement roof slabs can be unbearable for residents of higher-rise neighboring buildings. This is particularly noticeable for residents of units that are the same or nearly the same height as a low-rise block roof.

  On the roof of public houses, mechanical equipment such as water tanks and piping are usually installed. These are obstacles and it is difficult to introduce a typical sectioned rooftop greening system.

Generally, in current rooftop greening systems, plants are planted in the field and the initial surface coverage may be less than 60%. It may take nine months to one year to cover the whole. Under tropical weather conditions, there are the following disadvantages.
• Research has shown that on days with extremely high temperatures, the exposed growth medium is as hot as the concrete surface. Therefore, there is no merit of using the rooftop greening system.
-Plants that hold the growth medium, that is, because of insufficient roots, the growth medium will run out or be eroded by rain on a heavy rainy day.

  Various rooftop greening trays and systems are provided by the prior art. Japanese Patent Application Laid-Open No. 11-155369 discloses a cultivation tray having drain holes for discharging water in the tray on opposite side walls. However, this type of tray has the disadvantage that the drainage holes are easily clogged with fine particles, coagulum, stone chips, and the like, resulting in stagnant water in the tray. Also, under the tropical climate as described above, a large amount of rain falls during the monsoon season, so it is considered that this type of tray cannot discharge a large amount of rainwater well. Yet another disadvantage is that there is no way to retain rainwater except when the drainage hole is clogged because the drainage hole is provided at the lower end of the tray. Therefore, as a general rule, the plants on the tray must be watered, saving resources.

  Another rooftop greening system is disclosed in PCT / US01 / 22799. According to the invention, the tray is provided with ribs having drain holes for draining fluid under the tray, i.e. on the roof. This tray can hold a certain amount of fluid and is therefore superior to Japanese Patent Laid-Open No. 11-155369 in that it saves water resources, but it is clogged because it has a drain hole. It has the disadvantage that it can possibly drain well. A further disadvantage of the tray in this system is that rainwater is drained under the tray. As a result, rainwater accumulates under the tray without being noticed over a long period of time, which can cause water leakage from the roof and even mosquito breeding.

  The present invention aims to remedy one or all of the above problems.

  According to an embodiment of the present invention, a container for use in a rooftop greening system can be provided, the container having four side surfaces, the side surfaces defining a depth of the container, and a top end and a bottom end.
