Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purification block for purifying water in rivers and waterways using a mortar containing charcoal mixed with mortar and the like, and a water purification quay wall using the water purification block. Structure and water purification riverbed (including seawall hardening) structure.

[0002]

2. Description of the Related Art Conventionally, with regard to seawall technology for water purification of rivers, coasts, waterways, etc., a mortar layer is formed using a mortar containing charcoal in which mortar is mixed with charcoal, and this mortar layer is integrally formed on the surface. There has been proposed a revetment block constructed on the surface of a river bank or the like to purify water in a river or the like. Therefore, in this water purification seawall technology, microorganisms and algae adhere to the mortar layer due to the porosity of the charcoal contained in the charcoal-containing mortar, and the microorganisms and algae are one of the causes of pollution of rivers and waterways. Water purification of rivers and the like can be performed while promoting decomposition of water.

[0003]

However, in the conventional revetment technology for water purification, the mortar layer formed by the mortar containing charcoal is merely formed on the surface of the revetment block. As a result, water flows too smoothly along the surface, and the surface of the mortar layer is washed away by the water flow, so that it is difficult for microorganisms and algae to adhere to the mortar layer. However, there is a problem that decomposition of organic substances is hardly caused by the above. In addition, there is a mortar layer whose surface is formed into a crushed stone-shaped uneven surface.
That is, it is formed in a pseudo-stone shape in consideration of the decorative surface, and there is no intention to improve the ability to adhere microorganisms or to improve the ability to decompose organic substances by microorganisms and algae by the unevenness.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems. In a revetment technology for water purification using charcoal-containing mortar, the speed of a water flow contacting the charcoal-containing mortar is reduced. A water purification block capable of improving the ability of microorganisms and algae to adhere, and at the same time, improving the ability of microorganisms and algae to decompose organic matter, and a water purification revetment wall structure and a water purification riverbed structure using the water purification block. The task is to provide.

[0005]

In order to solve the above-mentioned problems, a water purifying block according to the present invention (claim 1) includes a main body block having a water passage hole penetrating therethrough. At least a part of the surface of the water hole has a structure in which a mortar body containing charcoal in which mortar is mixed with charcoal is formed. In this water purifying block, a mode in which the charcoal-containing mortar body is a charcoal-containing mortar layer (claim 2) and a mode in which a number of charcoal-containing mortar protrusions are integrally formed on the surface of the charcoal-containing mortar layer (claim). There is item 3). Also,
In this water purification block, there is a mode (claim 4) in which the charcoal-containing mortar body is a charcoal-containing mortar protrusion, and a number of such charcoal-containing mortar protrusions protrude from the surface of a water passage hole formed in the main body block. is there.

In the water purifying revetment structure using the water purifying block, there is provided a water purifying revetment wall structure in which a revetment wall such as a river, a shore, or a water channel is constructed using the water purifying block. There is a water purification riverbed structure (claim 6) constructed by using this water purification block to construct a riverbed (including a seawall) such as a river or a waterway.

In the water purification block of the present invention, a charcoal-containing mortar obtained by mixing charcoal or the like with mortar is formed on at least a part of the surface of a water passage hole formed through the inside of the main body block. Therefore, in a water purification revetment wall structure or a water purification riverbed structure using the same, the water flow passes through the water passage hole, and the resistance of the water flow when passing through the water passage hole weakens the momentum of the water flow and lowers the flow velocity. Therefore, the water flow through the water hole is
The contact with the mortar body with charcoal formed on the surface of the water hole is gently contacted, and the surface of the mortar with charcoal is not washed away. And the ability to generate algae can be improved, and the ability to decompose organic substances by microorganisms and algae can be improved. In particular, in the aspect in which the charcoal-containing mortar projections are formed (claims 3 and 4), the water flow becomes stagnant due to the charcoal-containing mortar projections, so that the flow velocity further decreases, and the generated algae is reduced. Algae can be prevented from being washed away because it is entangled with the mortar protrusions containing charcoal, and the ability to decompose organic substances by microorganisms and algae can be greatly improved. In addition, when the mortar protrusions containing charcoal are formed, garbage and leaves are attached to the mortar, earthworms and crabs are settled therein, and a favorable environment for algae growth is formed.
