Description

  The present invention relates to a civil engineering block used for a retaining wall and the like, and more particularly to a civil engineering block capable of performing solar power generation using the civil engineering block used for a retaining wall.

  Conventionally, retaining walls have been widely used to cut soil and fill in order to resist earth pressure and prevent soil collapse. For example, a retaining wall that covers slopes such as mountains, banks, river embankments, etc. facing roads with concrete retaining blocks and anchors the ground and blocks with anchors etc. to prevent landslides, etc. A structure is used (see Patent Document 1).

  In recent years, environmental measures have been demanded for civil engineering blocks including the earth retaining blocks as described above. However, environmental measures in the conventional civil engineering block are mainly performed by planting plants on the surface of the civil engineering block and greening them (see Patent Document 2).

  On the other hand, as a technique that can effectively utilize sunlight, a so-called driving form that integrates a so-called solar cell panel for performing photovoltaic power generation has been proposed (see Patent Document 3).

Japanese Patent Laid-Open No. 5-31660 JP 2000-2448569 A JP-A-8-239948

By the way, in order to perform solar power generation, securing a space for installing a solar power generation system is a big problem. In this regard, civil engineering blocks are said to be 6 million m ² per year just for retaining the earth. If this vast civil engineering block is used as a solar power generation installation space, the earth will be discharged due to carbon dioxide emissions, etc. Environmental problems such as global warming are solved and energy problems are also potentially solved.
However, at present, as described in Patent Document 3, a slightly driven formwork is only used as an installation space for photovoltaic power generation.
In addition, in order to effectively use sunlight, it is usually preferable to incline the solar cell panel by about 30 ° with respect to the horizontal plane, whereas, for example, the angle of the wall surface of a normal building is 90 °. In the case of the earth retaining wall, 60 ° to 90 °, which is a steeper slope than an appropriate inclination angle, the power generation efficiency is poor simply by providing a solar panel on the surface of the civil engineering block.

  The present invention has been made in view of the above problems, and effectively uses a civil engineering block such as a retaining wall having a large area as an installation location of a photovoltaic power generation system, and an installation angle of the photovoltaic power generation system. It is an object of the present invention to provide a civil engineering block capable of efficiently generating electric power with adjustable power.

  In order to achieve the above object, claim 1 of the present invention has a bottom plate portion, a retaining wall portion, and a top plate portion, and a concave portion surrounded by the bottom plate portion, the retaining wall portion, and the top plate portion is formed on the surface side. The civil engineering is characterized in that the installation angle of the solar cell panel can be adjusted within the recess of the block main body, and the solar cell panel comprises a support body that supports the solar cell panel and the solar cell panel. The content is a block.

  According to a third aspect of the present invention, there is provided the civil engineering block according to the second aspect, wherein an upper part and a lower part of the solar cell panel are supported by an adjusting member.

  A fourth aspect of the present invention includes the civil engineering block according to claim 2, wherein the solar cell panel is pivotally supported by a bearing and supported by an adjustment member. .

  According to a fifth aspect of the present invention, the adjusting member includes an inner tube and an outer tube, and the inner tube is slidably inserted into the outer tube. The contents are the civil engineering blocks.

  A sixth aspect of the present invention includes the civil engineering block according to any one of the first to fifth aspects, wherein the block main body includes at least one wall surface greening portion.

  In the civil engineering block of the present invention, the solar cell panel is provided in the recess surrounded by the bottom plate portion, the retaining wall portion, and the top plate portion. There is no danger of the panel being blown away. In addition, since the solar cell panel is protected in the recess during storage and transportation, it is possible to reduce the work at the site by incorporating the solar cell panel in advance in the factory, so that the construction cost can be kept low.

  Furthermore, since the angle of the solar cell panel can be adjusted, the power generation efficiency can be improved by adjusting the angle to an appropriate angle.

Using such a support member, both the upper and lower parts of the solar cell panel may be supported, and the solar cell panel is pivotally supported by a bearing and another part is adjusted using an adjustment member. You may support.
As the structure of the adjusting member, a structure including an inner tube and an outer tube, in which the inner tube is slidably inserted into the outer tube, is preferable.

  In addition, since the block body has at least one wall surface greening portion, the inorganic wall surface is transformed into a moist green wall surface and becomes a landscape countermeasure, and the wall greening portion has a hollow portion of the block body. It is preferable to provide a grid-like vegetation part.
