Generally, blocks containing cement as the main component are used for protecting the bank of the river and preventing scour.

As a block for the purpose of the above-described scour prevention, there is a Korean Patent Registration No. 10-0920490 (a porous lower floor protection block for restoration of a river ecology), which includes a frame portion formed along a rim and having a through- And a protrusion portion having a coupling protrusion protruding from at least one of the upper surface and the lower surface of the frame portion provided with the passage portion, wherein the frame portion There is disclosed a floor protecting block having a coupling portion formed with one side protruded outwardly and a recessed portion in which the other side of the frame portion is inserted inward so as to insert the coupling portion.

According to the above-described prior art, it is possible to prevent scouring of water at a high flow rate or falling water.

However, in the related art, when a neighboring lower floor protection block is coupled through a coupling portion and a recessed portion, a space is naturally generated between neighboring floor protection blocks and the rubble is filled in order to fill the generated space. There is a problem that is quite inconvenient.

In addition, since the neighboring lower floor protection block is coupled only through the coupling portion and the groove portion, the binding force is considerably weak, and when the falling water is applied to the lower floor protection block, lifting occurs and collides with the adjacent floor protection block. There is a problem that maintenance costs are incurred.

The object of the present invention is to provide a floor protection block and a method of constructing the floor protection block which can easily and easily be installed on a river floor and maximize the anti-scooping effect by increasing the binding force between the blocks.
