Description

  The present invention relates to a moss greening concrete body and a moss greening structure of a concrete body used for greening an upper surface with moss.

  As a countermeasure against the heat island phenomenon in an urban area, a technique has been proposed in which the upper surface of a concrete curb as a concrete body is greened by moss or the like (see Patent Document 1).

  This concrete curb greening technology forms a vegetation recess for vegetation and vegetation on the top surface, and the bottom of the recess is a first water retaining body made of a material with good water retention embedded in soil. In addition, a water permeable pipe communicating with the second water retentive body is provided, and a second water retentive body made of a material having good water retentivity is disposed on the wall surface forming the recess.

  Thus, the conventional concrete curb absorbs moisture from the water retaining body provided in the ground below the concrete curb as a water replenishment means for the greening plant using the water permeable pipe.

  For this reason, it is necessary to form a hydration system such that the water-permeable pipe is extended from the bottom surface of the recess formed in the concrete curb and is connected to the water-retaining body embedded in the soil. There is a problem that the structure becomes complicated and construction takes a lot of work.

The present applicant has already proposed a moss greening concrete body and a moss greening structure of a concrete body prior to the present application (see Japanese Patent Application No. 2006-226605).
In this prior art, a concrete surface to be planted on which the moss vegetation mat is laid is formed on the upper surface, a water storage recess is formed in the area of the concrete surface to be planted, and the moss vegetation mat is laid on the concrete surface to be planted. In the state, the water storage recess is formed to be covered with a moss vegetation mat.

In this way, a water storage recess is formed under the moss vegetation mat, and water (rain water, etc.) accumulated in the water storage recess evaporates. Therefore, the moss vegetation can be grown in a damp and humid environment suitable for moss growth. Mats can be laid.
In particular, the water storage recess is formed in the concrete body itself, and the moss vegetation mat directly absorbs the water evaporated from the water storage recess, so there is no need to form a special water supply system, and the structure is simple. In addition, the effect that the construction becomes easy can be obtained.

However, in the above-described prior art, the moss vegetation mat absorbs moisture due to evaporation of the water accumulated in the water storage recess, and this alone may not allow sufficient moisture to reach the moss vegetation mat. In this respect, there was room for improvement.

FIG. 1 is an exploded perspective view showing a first embodiment of the moss greening structure of the present invention, and FIG. 2 is a sectional view thereof.
The first embodiment is an example in which the concrete body for moss greening is a concrete curb block 1a. This concrete curb block 1a is a pedestrian boundary block laid on the boundary between the roadway and the sidewalk, and is manufactured at the factory. It is a concrete secondary product.

On the upper surface of the concrete curb block 1a, a laying concave portion 10 for fitting the moss vegetation mat 2 is formed, and the bottom surface of the laying concave portion 10 is a concrete surface to be planted for laying the moss vegetation mat 2 11 is formed.
And the water storage recessed part 3 by a circular hole is formed in the area | region of this greening concrete surface 11, and the said moss vegetation mat 2 is fitted in the recessed part 10 for laying, and laid in the greening concrete surface 11, The water storage recess 3 is formed so as to be covered with the moss vegetation mat 2.

  In addition, although the hole diameter of the water storage recess 3 is about 10 to 20 cm and the depth is about 10 to 20 cm, the shape is not limited to this, and the shape may be a circle, a square, or a groove, and the depth and arrangement thereof. The number of installations, the arrangement pitch, and the like can also be appropriately determined according to the size, shape, structure, etc. of the concrete body.

Further, a string-like body 4 as a water absorbing body is provided so as to extend from the water-reserving recess 3 to the moss vegetation mat 2, and the water accumulated in the water-retaining depression 3 due to the capillary phenomenon of the string-like body 4 is moss.
