TECHNICAL FIELD The present invention relates to a keystone mattress, and more particularly, to a keystone mattress and a method of constructing the same,

The present invention relates to a keystone mattress to be installed on a river bottom and a slope surface, and more particularly, to a keystone mattress which is constructed by a key structure for fixing a ground to a natural stone or artificial stone disposed on a wire net, And more particularly, to a keystone mattress and a method of constructing the same.

Recently, urbanization and industrialization are proceeding rapidly, and therefore the need for land use of the river basin is increasing. Therefore, for the purpose of the purpose of preventing the flood or the purpose of landscaping of the river basin, (Slope) is under construction.

Protective construction for protection of the waterproofing of the gutter or the surface has been mainly used to block the entire waterproofing of the river by the concrete by using the artificial concrete structure, but it is pointed out that it is not preferable because it is an environment where it is impossible to vegetate. Recently, as an alternative to solve the problems of the concrete blockage method, a method of constructing a protection structure using a construction stone on a river surface or a surface of a river has been attempted.

Korean Patent Registration No. 10-0817471 (a method of constructing a vegetation stone net for vegetation protection for rivers and floors and its construction method) has been proposed as a background of the present invention. In the background art, a block made of a natural stone or an artificial stone; A vegetation sheet disposed at a lower portion of the block and having a predetermined width and length and having plant seeds attached to its surface; A coconut fiber mat disposed between the block and the vegetation sheet and made of a coconut shell and having a surface woven in a lattice pattern using jute; A grid disposed at a lower portion of the vegetation sheet and having a net shape; And a set anchor penetrating through the grid and being press-fitted into the block.

However, the background art has a problem that the vegetation stone net is not fixed to the slope side, and the flow is lost if the flow velocity of the stream increases.

As another background of the present invention, Korean Patent Registration No. 10-0774880 (a construction stone fixing structure for fixing a construction stone by directly connecting upper and lower wire nettings) is a fixed structure to be fixed, And a plurality of fixing members for firmly fixing the construction stone by directly connecting the cover net and the bottom net to a certain extent in a space between the construction site and the construction site, Wherein the cover net comprises a plurality of ropes; And a connecting clip for connecting the ropes to each other, and the rope is connected to the connecting clip.

In this technique, there is a means for binding the cover net and the bottom net to the fixing member, but there is no means for fixing them to the ground, so that there is a problem that whole flow is generated when the flow velocity is narrow.
