Description

  The present invention relates to a greening pole for standing on a sidewalk, a park or the like and greening them.

  As a problem of the city of the near future, the problem of urban degeneration due to population decline is rapidly emerging.

  Population density will decrease and infrastructure in urban areas will be rapidly degraded.

  Securing greenery is indispensable to maintain and nurture a city with reduced tax revenue as a comfortable living space.

  A typical urban greenery is a roadside tree. Street trees are planted at intervals of about 8 to 12 meters as street tree planting regulations, but there are many cases where the trees are not necessarily in harmony with the beauty and landscape of trees. This is thought to be because the difference in growth rate and characteristics of the tree were not taken into account at the design stage. The tangle of the branches and the collapse of the tree shape due to strong pruning were conspicuous. Yes. I also often see that the roots of the trees lift the pavement.

  Trees continue to grow forever until they die. There is tree pruning management to suppress it.

  However, due to the decrease in tax revenue, the management area becomes smaller and the number of management times tends to decrease.

  The greening flow is starting to reverse. Greenery is needed to maintain a cityscape that will turn into a roadside tree in time.

  The condition must be a green lump full of vitality by photosynthesis and carbon assimilation.

  And I think that the charm full of beauty and change not found in the original tree is necessary. For example, the fact that some flowers bloom all year round is an attraction not found in trees.

  Accordingly, an object of the present invention is to provide a greening pole which is a new street tree that solves the above-mentioned problems, has a low management cost, and is kept beautiful in terms of scenery.

  In order to solve the above-described problems, the present invention provides a plurality of pillar portions that are provided standing on the ground at predetermined intervals in the circumferential direction, and a plurality of receiving plates that are provided on these pillar portions at intervals in the vertical direction. A cylindrical inner mesh layer provided on these backing plates and extending vertically; a core material for filling a space on the inner peripheral side of the inner mesh layer for growing plants; and an inner periphery on the outer periphery of the inner mesh layer A planting layer provided to cover the mesh layer for planting a plant, a water supply pipe provided in the planting layer for supplying water to the planting layer, and wound around the outer periphery of the planting layer And an outer mesh layer for holding the planting layer while allowing passage of plants implanted in the layer.

  A water retention container for accommodating the water retention layer may be provided on the receiving plate.

  A drainage hole for draining excess water in the water retention layer may be formed in the backing plate.

  It has a base part buried in the ground, and an insertion part for inserting the pillar part may be formed in the base part.

  It is preferable that three or more pillar portions are provided on the foundation portion and arranged in a ring shape.

  An ejection part for ejecting dry mist may be provided in the upper part of the implantation layer, and a dry mist supply pipe for supplying dry mist to the ejection part may be laid in the implantation layer.

  According to the present invention, it is possible to keep the landscape beauty for a long time with an inexpensive management cost.
