JP2019007321A - Permeable block with water storage function - Google Patents

Abstract

To provide a permeable block having a bottom surface or a side face to which processing treatment such as waterproofing is partially applied to provide a region prohibiting the passage of rainwater, thereby storing a large amount of rainwater in a block; a large amount of storage of water becomes a source of generation of a large amount of evaporation heat so as to keep lowering surrounding ambient temperature for a long time; this alleviates heat island phenomenon more effectively; furthermore, the permeable function of the block is conserved because the processing treatment such as waterproofing is applied only to a part thereof; and thus a novel permeable block is offered which is provided with a water storage function.SOLUTION: A permeable block is characterized in that the processing treatment such as waterproofing is applied partially to a bottom surface or a side face so that a water storage function for storing rainwater is added.SELECTED DRAWING: Figure 7

Description

The present invention relates to a water permeable block having a water storage function.

Conventionally, a water-permeable block has been focused on allowing rainwater and the like to permeate, and has no function of storing water in the block. In addition, there are products with improved water retention functions, such as water retention blocks, but there are no structurally similar blocks that have a water storage function similar to water permeable blocks.

In recent years, roadbed construction using permeable blocks has been carried out in various places in order to reduce the excessive burden on the drainage ditch due to guerrilla heavy rain. In addition, the construction is said to be effective in reducing the heat island phenomenon, and when the water remaining in the permeable block evaporates after it rains, it takes away the heat of evaporation, which is the so-called water spray effect. However, the water-permeable block was originally designed to allow rainwater to pass through, so the amount of water remaining in the block was overwhelmingly small. If the amount of water in the block is small, the effect of reducing the heat island phenomenon will not be sustained.
The present invention has been conceived in order to eliminate the above drawbacks.

For example, a part of the bottom and side surfaces of the water permeable block is subjected to processing such as waterproofing to provide an area through which rainwater cannot pass. That will collect a large amount of rainwater in the block, which acts as a water storage function.
This invention is a water-permeable block with a water storage function which consists of the above structure.

For example, if processing such as waterproofing is performed on a part of the bottom surface or the side surface of the water permeable block, the rain water cannot be passed through the portion and the rain water is accumulated in the block. A much larger amount of rainwater can be stored than conventional permeable blocks through which rainwater passes. A large amount of stored water is a resource that can generate a large amount of heat of vaporization, and the duration of the water spray effect is prolonged.
This can further improve the effect of the heat island phenomenon.
In the present invention, for example, the bottom surface and a part of the side surface of the water-permeable block are only subjected to processing such as waterproofing, so that the function of allowing rainwater to pass through is preserved. We will see the completion of the block which has two characteristics of water permeability and water storage with newly added water storage function. Moreover, if processing such as waterproofing is applied, it can be applied to any shaped object having a water-permeable function.
As an example of processing such as waterproofing, a large amount can be industrially processed by applying a paint having a waterproof function, which is generally marketed, to a target portion of the water-permeable block.

It is an example which performed the processings, such as waterproofing, to the bottom face and side surface of a water-permeable block.
Portions subjected to processing such as waterproofing are indicated by hatching.
