JP2008038452A - Concrete block having water retaining skeleton and water permeable head, and having epiphytic layer on front surface - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a concrete block which exerts an environmental conservation function. <P>SOLUTION: The concrete-stacked block is integrally formed of a skeleton 1 made of water retaining concrete, a head 2 made of water permeable concrete, and a plant epiphytic layer 3 made of a material effective for environmental conservation. A retaining wall constructed by using the concrete-stacked blocks thus formed functions to gradually evaporate retained water absorbed from a front surface of the block according to variation in ambient temperature and moisture, to thereby restrain the temperature from rising by virtue of heat of evaporation. The epiphytic layer helps adhesion of seeds and spores of plants, and water content supplement by evaporation contributes to budding and growth of plants. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention is a concrete block in which a skeleton excellent in water retention, a head excellent in water permeability, and an effective formation layer for plant growth and growth are integrated. The retaining wall constructed of the concrete block of the present invention absorbs external water into the block and gradually evaporates the water, thereby preventing global warming by the heat of vaporization, the wetting effect on the block surface and the formation layer Promote the greening of the wall by the action of.

There were water-retaining concrete (Patent Document 1) that uses water-retaining concrete alone, and pavement (Patent Document 2) in which water-retaining concrete is filled with a water-retaining material and integrated with ordinary concrete. There were no concrete building blocks that had greening functions such as settlement and cultivation.

  The conventional concrete block retaining wall is easily affected by the temperature, and its surface temperature is high in summer and low in winter, so it is easy to dry and there are almost no voids inside the wall. Therefore, the greening of the wall surface was difficult and it was harmful for the conservation of the natural environment such as prevention of global warming. The present invention has an effect of preventing global warming due to heat of vaporization because water absorbed in the voids inside the block is gradually evaporated. By maintaining the moist condition of the block surface and the effect of the epiphytic layer, the plant is easy to grow and grow, and the environment is preserved.

  The present invention relates to a retaining wall formed integrally using a water-retaining concrete housing 1 using a water-permeable concrete head 2 and a front surface thereof having an epiphysis layer 3 made of a substance effective for environmental conservation. Concrete block.

  The retaining wall constructed using the block of this plan continues to absorb the water that touches the surface of the block, such as spring water generated from the ground on the back of the wall body, during rainfall or river increase. Since the retained water once absorbed gradually evaporates according to the external temperature and humidity, the rise in temperature is suppressed by the heat of vaporization. Moreover, the replenishment effect of water by evaporation suppresses the drying of the retaining wall surface and promotes greening by the grown plants. Pumice and waste tiles used for the epiphysis layer make plant seeds and spores easy to settle due to surface irregularities and voids, and the shell has the effect of purifying water quality. The planted slope has various environmental conservation effects such as adsorption of carbon dioxide, supply of oxygen, and suppression of temperature rise on the retaining wall surface by the action of plants.

In order to produce water-retaining concrete that will be used as the block body 1, a suitable amount of AK-1 (trade name) released by Ast Japan Co., Ltd. is added to conventional concrete materials such as cement, gravel, sand, and water. Knead. (Patent Document 1) Porous concrete having an appropriate composition is used as the water-permeable concrete that becomes the head 2 of the block. Shells, pumice stones, waste tiles, etc. are crushed and used as environmentally effective materials for the formation layer 3. Crushed shells, pumice, and waste tiles can be used alone or mixed.

To manufacture the block, install a formwork with an appropriate shape and sufficient strength. On top of that, a permeable concrete to be the head is thrown and shaken. Furthermore, after uniformly spreading a substance effective for environmental conservation, which becomes a hardened layer, on the upper surface and uniformly pressurizing the whole, the frame is removed and cured in the same manner as in the case of conventional immediate de-concrete. The method of constructing the block stacking wall using the block after finishing the curing is the same as the conventional block stacking wall.

The block of the present invention has an environmental protection function added to a conventional concrete building block. The equipment and technology for constructing the block retaining wall are the same as those of the conventional concrete building block. The aesthetics are the same as the conventional block stacking walls.

The block of the present invention can be produced in a large amount in a factory like a conventional concrete building block, and has industrial applicability.

It is a perspective view at the time of applying this plan to a cognitive block. It is sectional drawing of the river revetment using the block of this plan.

Claims (3)

A concrete block composed of a water-retaining concrete frame 1, a water-permeable concrete head 2, and a formation layer 3 made of a material effective for environmental conservation. The settlement layer 3 is a concrete block made of pulverized pumice, shells, waste tiles and the like, and these materials can be used alone or in combination. In order to manufacture this, using a formwork that matches the shape of the block, water-retaining concrete that will be the housing 1 and water-permeable concrete that will be the head 2 will be put on it, and finally the material that will become the formation layer 3. A concrete block that is pressure-molded in one piece with an appropriate amount added.
