As shown in Figures 1 to 4, the surface protection block 100 according to a preferred embodiment of the present invention is installed on the surface in order to prevent the loss of soil and collapse of the inclined surface, respectively projecting portion 122 and The connection part 120 in which the fitting part 124 is formed has the long rod-shaped body 110 formed in mutual symmetry, respectively. The vertical groove 126 is formed at the end of the connecting portion 120. As shown in FIG. 5, the vertical grooves 126 form one vertical hole 128 as the vertical grooves 126 are connected in series when a plurality of front surface protection blocks are connected in a horizontal and vertical or diagonal direction. . The vertical hole 128 formed by the vertical grooves 126 is a hole for embedding an anchor rod or filling mortar in order to prevent a slim phenomenon of the block when the surface to be constructed is a steep slope or soft ground.

On the other hand, the body 110 is provided with a flange 140 formed wider than the upper end on both sides 112, the lower end portion so as to be buried in a stable surface. For example, as shown in Figure 3, the front surface protection block 100 is installed on the surface after being buried by the earth and sand by pressing the flange 140 in the vertical direction by the earth pressure, the front surface protection block 100 on the surface It can be installed more stably.

In addition, the upper surface 114 of the body 110 is formed with a waterway 130 that can drain rainwater (rainwater) flowing through the ground surface during the rain quickly and smoothly. The water channel 130 has a unique shape of the bottom 132 and both sides 136 to prevent the water flow of rainwater faster as it flows down the surface. As shown in FIG. 4, the bottom 132 is formed by successive stepped slopes 132a. 'Consists of shapes.

And, as shown in FIG. 3, the two side surfaces 136 are gradually widened in width, and are rapidly narrowed by the jaws 136a, and gradually widened again. 'Consists of shapes. The waterway 130 consisting of the bottom 132 and both side surfaces 136 of this unusual structure will be able to flow stably up to the drainage channel (not shown) of the lower surface of the law.

The structural feature of the present invention is to have a flange on the lower side of both sides of the body to be more stably embedded in the law. And another structural feature of the present invention is to have a channel that can mitigate the flow rate of rainwater flowing down through the channel.
