Abstract

PURPOSE:To maintain drainage function, by a method wherein a drainage pipe having holes is buried in a block body which is produced such that cement, water, porous light aggregate, an organic material, such as shells, chaff, which is eroded by an acid and bacilli in soil, are kneaded and molded. CONSTITUTION:A block body 1 is produced such that cement, water, porous light aggregate, an organic material, such as shells, chaff, which is eroded by an acid and bacilli in soil, are kneaded and molded, and a porous drainage pipe 2 is buried in the body 1 to form a drainage block A. The blocks A are placed in an excavated ditch, a connecting pipe 3 is engaged with and between the drainage pipes 2 of the adjoining blocks A to join together the two blocks A. After cobble-stones 4 are laid on both sides of the block A, the blocks A are covered with organic fertilizer 5 and earth 6. This increases water and air permeability through erosion of the organic material for years, resulting in the possibility to maintain normally constant draining ability.

Description

[Detailed Description of the Invention] Conventional culverts are constructed by excavating earth and sand and burying unglazed clay pipes, perforated pipes, etc. at the bottom of the excavated hole, or by constructing ordinary concrete blocks for waterways with through holes in the side walls. It was constructed by placing chestnut stone, etc., and burying it on both sides and at the top of the block.

These drainage pipes fulfill their function when they are first installed, but they gradually become clogged due to the intrusion of plant roots, and in the case of unglazed earthen pipes, they become clogged with clay and no longer fulfill their function1. If left untreated, it will affect not only the initial water function but also the living organisms of plants.

The present invention was proposed in order to solve these problems, and it uses organic phase materials that are eroded by bacteria, such as cement, water, porous lightweight aggregate, shells, and rice husks, in soil, and water. This invention relates to a drainage block characterized in that a perforated drainage pipe is embedded in a concrete block main body formed by kneading and molding the following.

In the drainage block according to the present invention, porous lightweight aggregate such as perlite and pumice is used as the concrete aggregate constituting the block body, so the water permeability of the block body is ensured, and the block Since a perforated drainage pipe is buried in the main body, the drainage performance of the block is maintained by the drainage pipe, and rainwater, spring water, etc. at the site where the block is installed can be removed without any problem.

In addition, in the concrete constituting the drainage block body according to the present invention, there are shells such as oyster shells that are eroded by neutralization with acids in the soil, and shells such as rice husks that are eroded by bacteria in the soil. Since the IA additive is contained, the concrete does not become denser and stronger over time as in conventional concrete, but on the contrary, the organic additive corrodes over many years. It maintains water permeability and air permeability, and always maintains a certain level of drainage.

Historically, in the present invention, soil conditions,
It is possible to create a porosity and corrosiveness according to the vegetation.

Furthermore, since the drainage block according to the present invention is molded from concrete containing lightweight aggregate and organic material as described above, it is lightweight and easy to handle.

The present invention will be described below with reference to the illustrated embodiments.

(1) is for drainage made by kneading and molding water and porous lightweight aggregates such as cement, sand, orite, and pumice, as well as organic materials such as rice husks, oyster shells, and other shells. A large number of through-hole 7I-3 shoulder hole drain pipes (2) are embedded in the center or lower part of the block body (1) so as to penetrate through the block body (1). In addition, the upper half of the same perforated drainage pipe (2) has a large diameter hole (2α), and the lower half has a small diameter hole (2h), but it has an impermeable structure. There is.

When installing the υ1 water block (A) constructed in this way, as shown in Figures 6 and 4, the earth and sand at the installation location is excavated and leveled, and the block (A) is installed. , a connecting pipe (3) is fitted between the perforated drainage pipes (2) of the adjacent drainage blocks (A) (A) to join both blocks. This connecting pipe (3) is effective for water flow between the flocks and for preventing uneven settlement when the blocks fall over.

When the water control block (A) is connected and buried in a predetermined position, chestnut stones (4) are lined up on both sides of the block (4) to prevent each block (4) from moving sideways and improve drainage. hold.

Next, if you want to promote plant growth, bury organic fertilizer (5) on the block (N), and then cover it with earth and sand (6) to complete the installation of the drainage block (N). .

In addition, when the water control block (A) is laid between trees, a reliable drainage effect can be obtained, so the vinyl coating (7
) and drip seawater facilities (8) can be installed, making it possible to irrigate while ensuring water control and ventilation, which are essential for plant growth.Therefore, this drainage block is particularly effective for orchard v1 water. be.

The present invention has been described above using an actual Mli example, but the present invention is of course similar to 7c'J,! The present invention is not limited to the examples, and various modifications may be made to Proposition 1 without departing from the spirit of the present invention.

Claims (1)

[Claims] A perforated drainage pipe is installed inside the concrete block body, which is made by kneading and molding cement, water, porous lightweight aggregate, organic materials that are eroded by acids and bacteria in the soil, such as seashells and rice husks, and water. A drainage block characterized by being buried.
