Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a permeable tree planting tree having a novel structure.

[0002]

[Prior art]

 The conventional planting stake is a general concrete secondary processed product, and the result is that the sprayed water washed from the road sprays dirt and dirt dust on the road onto the soil around the trees in the planting stake. If this is repeated over a long period of time, the oxygen supply necessary for planting will not be distributed to the root part of the tree, and water such as rainwater will not be able to penetrate into the soil, creating a very bad environment for the growth of street trees. The reality is that many tree species decay and die.

[0003]

[Problems to be solved by the device]

 The conventional techniques described above have the following problems. Water, oxygen, and nutrition are essential conditions for growing plants. In recent years, most of urban areas are covered with buildings and pavements, and bare land and green areas where rainwater can penetrate are decreasing. Therefore, once the rainwater falls, it will be washed away in a short time and cannot penetrate into the ground to circulate to groundwater. Therefore, trees surrounded by pavement such as street trees cause water shortage especially in the dry season of summer, and it is difficult to supply oxygen to roots.

The present application has been made in view of such problems of the conventional technique, and an object of the present application is to provide the following things. Among the three elements for plant growth, a flowerbed-type permeable planting basin was devised to smoothly supply water and oxygen. The following effects were aimed at by using a water-permeable planting tree made of water-permeable concrete. 1. Since it is about 30 cm higher than the sidewalk, oxygen can be supplied from the side (4) and 5 sides. 2. It becomes easy to supply rainwater and oxygen to the root through the porous part of the permeable tree. 3. Contributes to breathability, strength, freedom of color, freedom of finishing aggregate, and landscape.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is as follows. That is, in the present invention, the sidewalk side block portion 1A arranged along the sidewalk on the sidewalk side of the curb 2 and the both ends of the sidewalk side block portion 1A are connected in a direction orthogonal to the longitudinal direction of the sidewalk 2A. Consists of a side block 1B, left and right corner blocks 1C and 1C continuously provided at the inner end of the side block 1B, and an inner block portion 1D arranged between the left and right corner blocks 1C and 1C Each block is made of porous concrete, and the height of the sidewalk block 1A is higher than that of the sidewalk surface 2A1 of the sidewalk 2A, and the height of the side block 1B and the corner block. The height of 1C and the height of the inner block portion 1D are permeable tree planting blocks that are configured at the same level as the height of the sidewalk block portion 1A.

In this case, each block can be configured to be higher than the sidewalk surface 2A1 of the sidewalk 2A by about 300 mm. Further, known invert hangers 1B2, 1C2, 1D2 can be planted horizontally on the inner surfaces of the side blocks 1B, the corner blocks 1C, and the inner block unit 1D1.

【Example】

 Examples will be described with reference to the drawings. Reference numeral 1 is a water-permeable planting tree constructed of porous concrete of the present invention. Reference numeral 2 is a known curb disposed between the sidewalk 2A and the road 2B. 1A is a sidewalk-side block portion arranged along the sidewalk on the sidewalk side of the curb 2, and this sidewalk-side block portion is composed of an appropriate number of sidewalk-side block units 1A1. In the illustrated case, the number is three.

Reference numeral 1B is a side block continuously provided at both ends of the sidewalk-side block portion 1A in a direction orthogonal to the longitudinal direction of the sidewalk 2A. Reference numerals 1C and 1C are left and right corner blocks which are connected to the inner ends of the side blocks 1B and which are substantially L-shaped in a plane. Reference numeral 1D denotes an inner block portion arranged between the left and right corner blocks 1C, 1C, which is composed of a proper number of inner block units 1D1. In the case shown, it is two. Reference numeral 3 is a well-known hollow for a customer's earth which is dug with a predetermined depth in a portion surrounded by the sidewalk side block portion 1A, the side block 1B, the corner block 1C, and the inner block portion 1D. 3A is the tourist land.

Therefore, the height of the sidewalk block portion 1A is configured to be higher than that of the sidewalk surface 2A1 of the sidewalk 2A, and the height of the side block 1B, the height of the corner block 1C, and the inner block portion 1D. The height of the building is the same as that of the sidewalk block 1A. In this case, each block is constructed about 300 mm higher than the sidewalk surface 2A1 of the sidewalk 2A.

Known invert hangers 1B2, 1C2, 1D2 are planted horizontally on the inner surfaces of the side blocks 1B, the corner blocks 1C, and the inner block unit 1D1. The height of each block is 400 mm and the width is about 200 mm. In the figure, 4 is a foundation notch material, 5 is foundation concrete, and 6 is leveling mortar.

Note that porous concrete will be additionally described. Conventionally, it has been ideal that concrete is dense concrete with low air permeability and water permeability, and its application field was limited to the range where this property could be exhibited. The permeable concrete is a porous concrete (Porous Concrete) in which the range of the aggregate grain size is limited and it is joined by a special cement paste to form continuous voids. This is a special manufacturing method, and voids having a size of about 0.5 mm to 0.8 mm are continuously formed in the entire product. The permeable tree plant 1 is composed of a known standard composition for this porous concrete.

The operation will be described together with the effect.

[Effect of device]

 INDUSTRIAL APPLICABILITY As described above, the present invention is constructed by applying the advantages of water-permeable concrete to a tree planting tree, and therefore has the following effects. 1. Oxygen and water, which are essential elements of the plant, can be naturally supplied from this porous portion (void) to promote the growth of the plant. 2. Also in the mold body, since the same height as the conventional sidewalk surface is configured to be about 30 cm higher than the sidewalk surface, oxygen can be effectively supplied from the side surface. 3. In addition, by increasing the height in this way, it is possible to achieve the conventional purpose of preventing the soil from becoming dry and dry.

As a result, the topsoil can always keep a natural body due to the influence of the snowmelt season in a road with snowfall, and natural water can easily infiltrate due to rainfall. 4. The following effects can be expected because the sidewalk block 1A is formed on the sidewalk of the curb 2 along the sidewalk. The pedestrian side block portion 1A can prevent solidification and drying of the topsoil caused by accumulated dust such as sludge and car dust from the road cleaning car on the soil. 5. Since the invert hangers 1B2, 1C2, 1D2 are planted, the following effects can be expected. Conventional tree planting is a wind damage countermeasure that relies only on splints, but it has the effect of further stabilizing the tree before rooting by supporting it at two points with the underground part.
