Abstract

PURPOSE:To maintain a landscape beautiful and to allow under-water creatures to live by providing grooves enough large to cultivate plants on the upper face of concrete material and studding drain holes on the bottom or near the bottom of the groove. CONSTITUTION:A groove 3 is formed on the face 2, which is the top block of a large block 1, and a drain hole 4 is also penetrated in the bottom or near the bottom of the groove 3. In the groove 3 soil is put and some plants, iris 11, for example, are cultivated. On the other hand, in the case where these blocks 1 are installed in rivers, which contact with the water surface 7, through holes 12 are made on the portions, which are always under the water surface, and extend to corrosion-resistant and water permeable cages 13 resulting in the formation of fish nest.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method for growing vegetation on the upper surface of an embankment that is in constant contact with the water surface of a river, an embankment that protects a riverbed, a concrete embankment on a road with a cliff, etc. The present invention relates to a landscaping embankment body that moisturizes concrete structures, which tend to have a bland landscape, and landscaping blocks used therefor.

(Conventional technology) In the past, in rivers, etc., cliffs were naturally formed along the flow of water, and rocks were exposed to form stable waterways.However, when the flow rate increases due to flooding, etc. Constructing artificial embankments to avoid flooding is an unavoidable necessity for the effective use of national land.In this case, the outside of the embankment should be left in its natural state, and the riverbed should be widened to meet the water surface. They often form dam bodies that do not touch each other.

In order to more effectively prevent river flooding, it is necessary to construct strong embankments made of concrete, including the parts that come into contact with the water surface.

[Problem to be solved by the invention]

However, the artificial concrete surface lacks moisture, and is difficult for organisms such as fish that live in the water to form natural cracks.
The environment is deteriorating and aquatic life is decreasing because there are no shelters such as crevices between rocks. In addition, water areas surrounded by concrete are lacking in moisture and seriously impede the landscape. Therefore, when carrying out bank protection work using concrete,
There was a need for a landscaping embankment body and landscaping blocks for use in it that would preserve the beauty of the landscape and ensure the habitat of aquatic life.

[Means of problem solving]

The present invention aims to solve the above-mentioned problems, and its configuration is such that, in an embankment whose bearing surface is protected using concrete material in a terrain with cliffs, the size is such that vegetation can grow on the upper surface of the concrete material. A groove is provided, the groove is filled with earth and sand, and various plants are grown in the groove, and the groove is characterized by having drainage holes scattered at or near the bottom of the groove.

In the present invention, the landform having a cliff is a landform having a slope, such as a water surface of a river, an embankment, and a road that crosses a slope. These are effectively protected by covering their surfaces with concrete materials to prevent river flooding, safe traffic for people and vehicles, and safety of houses and other structures hugging cliffs.

Therefore, the term levee body is not limited to embankments in the narrow sense of rivers, coasts, etc., but also includes slopes of roads, slopes near structures, etc.

In such an embankment body, the present invention provides a groove on the upper surface of the concrete material, fills the groove with soil, and grows various types of vegetation. Therefore, the size of the groove is limited to a range that does not affect the concrete thickness and strength of the embankment body, and it must be large. For example, if the width of the top surface is 25 cm or more, it must have a width of 10 cm or more to contain soil. It is possible to secure the minimum size for vegetation to grow, but preferably the width is 30 cm to 40 cm or more.

That is, since the upper surface of the embankment body forms an endless flower pot, a drainage hole is provided at the bottom of the groove.

The purpose of the present invention can be achieved as long as the drain hole is not necessarily located at the bottom but also at the side.

Although it is possible to construct such an embankment by directly pouring concrete, as shown in Figure 1, a groove large enough to allow vegetation to grow in the area that will become the top surface when constructed is shown in Figure 1. Then, large blocks with drainage holes drilled at or near the bottom may be placed and arranged at the top of the embankment body.

Furthermore, when constructing the present invention in a river that is in contact with the water surface, in order to secure an evacuation place for underwater fish, etc., a through hole is drilled in the concrete part that is always below the water surface, and this through hole is deformed by earth pressure. It has enough rigidity to prevent corrosion, and forms a fish nest when connected to a corrosion-resistant and water-permeable electric body. If the fish are in danger, they escape into the cage through this hole, and the cage is always filled with river water and is connected to the strata in the hinterland, so it receives groundwater supply during times of drought. It will be done.

Electrical materials include plastics, corrosion-resistant metals,
A perforated frame made of ceramic such as concrete is used. Among these, materials such as hard vinyl chloride with many perforations are preferred.

[Effect]

In the present invention, a groove is provided on the uppermost surface of the embankment body, and a drain hole is provided at the bottom of this groove. Therefore, the upper surface of the embankment body is like having endless flowerpots, and the vegetation grows thickly, adding moisture to the bland concrete material. In particular, when installed on an embankment that is in contact with the water surface, there is a synergistic effect between the water surface and the beauty of the vegetation, and because there are many fish nests under the water surface, many fish live there and the natural moisture is lost. It is possible to build an artificial dam without having to do so.

Furthermore, since the groove is provided at the top of the embankment, the strength of the embankment is not adversely affected.

[Example] FIG. 1 is a perspective view of a large block used in this example. 1 is a large block, and 2 is the top surface when constructed. Reference numeral 3 indicates a groove provided in the surface that will be the topmost part when the construction is completed, and reference numeral 4 indicates a drainage hole extending from the lower part of the side surface and communicating with the rear land 5. In this example, as shown in Figure 2, hard concrete with a slump close to 0 was used for the embankment body that is in direct contact with the water surface, so moss tends to grow on the surface, and in order to create unevenness that fish like, hard concrete with a slump close to 0 was used as a natural layer surface. was attached to the transferred shape. 6 is an uneven surface.

In FIG. 2, a through hole 12 is further drilled in the lower part of the large block 1, a pipe is passed through this through hole, and the pipe and mass body 13 are inserted.
were closely connected to form a fish nest. Although a part of the mass 13 is buried in the large block 1, there is no problem even if the entire mass is located in the hinterland. 14 is a dam that further protects the riverbed.

〔effect〕

According to the landscaping embankment body of the present invention, destruction of the natural scenery caused by the concrete material used for the embankment body can be alleviated by allowing vegetation to flourish.
