Description

Grass mat system {MAT SYSTEM FOR PREVENTING WEEDS}

The present invention relates to a grass mat system, and more particularly, to a grass mat system for preventing weed growth around road facilities such as roadsides, guard rails, and electric fences.

Weeds growing on highways or roadsides cause traffic accidents by corroding or damaging traffic facilities or obstructing the driver's vision when driving a vehicle. In particular, since the roadside where the guardrail is installed is in an optimal state for growing weeds due to severe exposure of the soil and a large amount of sunlight, there is an inconvenience that the weed removal operation must be performed frequently. In order to prevent this, a grass mat is installed on the side of the road where the guard rail is installed to suppress the growth of weeds.

The grass mat not only suppresses the growth of weeds, but also improves the aesthetics of the roadside and prevents the deformation of the road structure by blocking radiant heat, and also prevents soil from spilling into the road in rainy weather, or causing damage to the growth of street trees, etc. Prevent it.

In general, a grass mat made of a fibrous material is constructed by fixing one end to the post of a post stone or guard rail, and fixing the other end to the ground with a nail or spike. At this time, to install grass mats on long and wide roads, cut them into appropriate lengths and connect them with nails or spikes, which loosens the connection between grass mats and allows gaps between grass mats when spikes or nails fall off. As sea weeds grew, it frequently caused damage to the grass mat.

In addition, if the mat is cut and glued together, the cutting surface and the connecting surface are not smooth, which not only impairs the aesthetics, but also has a high risk of being separated from the guard rail or the pillar stone, and it is difficult to repair the damaged area for maintenance. There are also many disadvantages.
