Description

Production of water-permeable grass block type hybrid grass turf with plant waste recycling and its construction method to hybrid turf}

The present invention relates to a hybrid permeable grass block and a method of constructing a lawn using the same. More specifically, the present invention relates to a hybrid permeable grass block and a method of constructing a lawn using the same. More specifically, it can solve the difficulties of manufacturing and maintaining a permeable grass block with natural grass attached, and can recycle plant by-products. This is about a new plant by-product recycling hybrid type permeable grass block and a method of constructing a lawn using it.

Various plant by-products or agricultural by-products are generated through various agricultural activities, including distribution, and the disposal of these by-products is emerging as a global environmental problem. It is known that domestic farms produce about 10 million tons of agricultural by-products every year. Although some of these agricultural by-products are reduced, most are incinerated or left behind as waste. However, this treatment method is causing another environmental problem due to the waste of biological resources, and is a huge burden, especially at this time when carbon neutrality must be achieved.

In addition, in Korea, in addition to agricultural by-products, various plant by-products such as plant-derived food, waste wood, fallen leaves, and green algae are generated in industrial or forestry fields, but the areas where these plant by-products can be reused in an environmentally friendly manner are limited.

Meanwhile, methods for planting natural grass on permeable blocks are being developed. In Korean Patent Publication No. 10-2004-0099935, a) a process of preparing a lawn landscaping block by applying a vegetation layer containing grass, fertilizer and soil on a pervious concrete block; b) a process of attaching the grass to the permeable concrete block; and c) providing a lawn landscaping method using pervious concrete blocks, including a step of installing the lawn landscaping blocks on a lawn greening target site. To this end, a pervious concrete block (11) of a certain shape having a planting space (22) is manufactured, and the planting space (22) is filled with soil mixed with grass seeds and fertilizers so that grass can grow (33), It provides a process of inserting grass stems instead of grass seeds, growing the grass until it settles on the block, and constructing the grass landscaping blocks thus created like regular blocks for creating or repairing a lawn. Through this, a grass block as shown in Figure 11 is provided.

However, this process not only requires a separate settlement process, but also has the problem that it is difficult to survive and become established due to the long winters due to the characteristics of the domestic climate. Additionally, when these blocks are used as blocks for pedestrians to pass through, there is a problem that the grass is easily killed by stepping on the hard sidewalk blocks.

Additionally, there is a need for new vegetation blocks that can solve the problems of grass vegetation blocks and promote recycling of plant by-products that should be classified as waste and disposed of.

The problem to be solved by the present invention is to solve the complex rooting problem that occurs when natural grass is planted on a permeable block, the problem that the grass dies by being stepped on and compressed into the block when used as a sidewalk block, and the problem of domestic climate characteristics. The goal is to provide a new hybrid permeable grass block that can recycle plant by-products that are classified as waste.
