上記前者においては、特殊なレールを必要とするため、必然的にコスト高となる。
また、含水時の支持力不足により、変形し、こわれやすく、芝生育成が困難となる。
さらに、通水性のある底面であり、保水効果がなく、乾水時において水を補充しなければならない。
さらにまた、緑化方法においても特殊レールを配置しなければならず、多大な労力を要する。In the former, since a special rail is required, the cost is inevitably increased.
In addition, due to lack of support when wet, it tends to deform and break, making it difficult to grow grass.
Furthermore, it is a water-permeable bottom surface, has no water retention effect, and must be replenished with water when dry.
Furthermore, a special rail must be arranged in the greening method, which requires a lot of labor.

上記後者においても、通水部を設けてあり、乾水時に水の補充をしなければいけない。
また、緑化植物を交換する場合において、皿型容器と一体化しており、交換（取替）が非常に面倒で、時間が掛るものである。
さらに、緑化方法においても皿型容器同士を連結しなければならず、多大な費用と労力が必要となり、車両等の通行による支持力はあるものの、制動力は芝生にかかり、その育成を妨げる。Even in the latter case, a water passage portion is provided and water must be replenished during dry water.
Moreover, when replacing a greening plant, it is integrated with a dish-shaped container, and replacement (replacement) is very troublesome and takes time.
Furthermore, even in the greening method, the dish-shaped containers must be connected to each other, which requires a great deal of cost and labor. Although there is a supporting force due to the passage of a vehicle or the like, the braking force is applied to the lawn and hinders its growth.

本発明は、上記のような問題点に鑑みなされたもので、スベリ止部を形成することにより、車の走行の安全性を確立させると共に各植物栽培室の下部に貯水部を設けることにより、一年中安定した水を貯めることが出来る。
また、貯水部の底面より突出する水路部により、均一な水量を確保できる。
さらに、メッシュ板によりクッション材となると共に、植物栽培床の変形や傷付けることを防止できる。
さらにまた、流入部により、各植物栽培室に均一な水量を確保できる。
吸水ひもを設けることにより、より確実に水を植物に与えることができ、鋳鉄製とすることにより、マンホールと同様、長期使用可能となる。
緑化方法においても、植物栽培床を簡単に設置及び交換できる路面電車軌道用緑化容器及び路面電車軌道の緑化方法を提供することを目的とする。The present invention was made in view of the problems as described above, and by forming a slip prevention portion, by establishing a water storage portion at the bottom of each plant cultivation room while establishing the safety of traveling of the car, Stable water can be stored all year round.
In addition, a uniform amount of water can be secured by the water channel protruding from the bottom surface of the water reservoir.
Furthermore, it becomes a cushion material with a mesh board, and can prevent a plant cultivation floor from being deformed or damaged.
Furthermore, the inflow part can ensure a uniform amount of water in each plant cultivation room.
By providing a water absorption string, water can be more reliably supplied to the plant, and by using cast iron, it can be used for a long time, like a manhole.
Also in the greening method, it aims at providing the greening container for streetcar tracks and the greening method of a streetcar track which can install and exchange a plant cultivation floor easily.
