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 and other materials buried on both sides and at the top of the block.

These drainage materials perform their function when they are first laid, but they gradually become clogged due to the intrusion of plant roots, and unglazed earthen pipes become clogged with clay and no longer perform their function, so they are left as they are. If left untreated, it will affect not only the drainage function but also the living organisms of plants.

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

In the drainage block according to the present invention, as aggregate for concrete constituting the block body,
Since porous lightweight aggregates such as perlite and pumice are used, the water permeability of the block body is ensured.
Further, since a perforated drainage pipe is buried in the main body of the block, 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, the concrete constituting the main body of the drainage block according to the present invention contains shells such as oyster shells, which are eroded by neutralization with acids in the soil, and rice husks, which are eroded by bacteria in the soil. Concrete does not become denser and stronger over time, unlike conventional concrete, because it contains organic materials such as organic materials. It increases water permeability and air permeability, and always maintains a certain level of drainage performance.

Furthermore, in the present invention, by changing the mixing ratio of the block body concrete according to the purpose, it is possible to create a porosity and corrosiveness according to soil conditions and 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 a drainage block body made by kneading and molding water and organic materials such as cement, sand, porous lightweight aggregates such as perlite and pumice, and organic materials such as rice husks, oyster shells, and other shells. A perforated drain pipe 2 having a large number of through holes is buried in the center or lower part of the block body 1 so as to pass through the block body 1. Although the perforated drain pipe 2 has a large diameter through hole 2a in the upper half and a small diameter through hole 2b in the lower half, it has an impermeable structure.

When installing the drainage block A constructed in this manner, the earth and sand at the installation location is excavated and leveled as shown in FIGS.
At the same time, the adjacent drainage block A,
A connecting pipe 3 is fitted between the perforated drain pipes 2 and 2 of A to join both blocks together. This connecting pipe 3 is effective in passing water between the blocks and preventing the blocks from overturning and uneven settling.

In this way, the drainage block A is connected to the specified position.
When buried, chestnut stones 4 are placed on both sides of the blocks A to prevent them from moving laterally and to maintain drainage.

Next, if the growth of plants is to be promoted, an organic fertilizer 5 or the like is buried on the block A, and the soil is further covered with earth and sand 6 to complete the installation of the drainage block A.

In addition, when the drainage block A is installed between trees, a reliable drainage effect can be obtained, so it is also possible to install a vinyl coating 7 and a drip irrigation facility 8, which provides drainage and ventilation necessary for plant growth. This makes it possible to irrigate while ensuring water is maintained, and therefore this drainage block is particularly effective for orchard drainage.

Although the present invention has been described above with reference to embodiments, the present invention is, of course, not limited to such embodiments, and can be modified in various ways without departing from the spirit of the present invention. .
