Description

Eco-friendly porous gravel block manufacturing method {ECO FRIENDLY POROUS GRAVEL BLOCK MANUFACTURING METHOD}

The present invention relates to a method for manufacturing an eco-friendly porous gravel block, and in detail, by replacing natural stone (amber stone, processed stone, sandstone, stepping stone, stair stone, etc.) mainly used in conventional stone nets, gravel (crushed stone or recycled aggregate), etc. Problems such as supply and demand of natural stone and environmental destruction (stone destruction, etc.) by providing a porous gravel block (molded body) with pores formed between the gravel as a main material, and manufacturing a stone net using the gravel block To solve the problem, it relates to an eco-friendly porous gravel block manufacturing method that can purify water in an environmentally friendly manner through permeability and breathability.

In general, in the case of urban rivers with high land use density around rivers, slope protection works or river scour prevention works are performed to protect the slopes around the rivers. Such slope protection construction or river scour prevention construction mainly consisted of a construction method in which the entire river was blocked into a concrete structure using an initial artificial concrete structure.

However, the construction method of blocking with a concrete structure physically blocks the penetration of river water into the soil layer to build up vegetation plants along the natural river, while the shade provided by the vegetation along the river disappears, resulting in extreme changes in water temperature. It has lost its function as a habitat for fish and spawning, and has caused a problem of damaging the habitat of algae that take food around riverside vegetation and hide in the vegetation undergrowth.

Due to this problem, efforts have recently been made to construct more nature-friendly slopes such as river shores or slopes instead of concrete blocks, and stone net construction methods using natural stone or processed stone are known.

The stone net is usually a stone block made of natural or processed stone, and a grid, such as a wire mesh or synthetic resin mesh, fixedly fastened with the stone block so that a plurality of stone blocks can be stably settled on the foundation ground corresponding to the slope, and stone blocks. And an anchor for firmly fixing and fastening the grid and the anchor, and a plate fastened to a predetermined portion of the anchor corresponding to a position between the grid and the foundation ground to prevent separation of the anchor.

However, as the stone net according to the prior art is manufactured using natural stones mainly collected from nature such as amber stone, processed stone, sandstone, stepping stone, stepping stone, etc., manufacturing is not smooth due to the supply and demand problem of natural stone. In order to do so, it is necessary to destroy the rocks and the like, and thus, indiscriminate environmental destruction occurred.
