As shown in FIG. 2, the embankment block according to the present invention includes a base frame 30 having a center portion with a through hole, and a plurality of connection members 32 downwardly extended from a rim of the base frame 30.
The base frame 30 is formed of a rectangular frame shape having a certain width. The base frame 30 includes a through hole 34 formed at its center. A plurality of partition plates 36 partition the through hole 34 by a certain width.
The connection members 32 are downwardly extended from an outer surface of a rim of the base frame 30, and a connection part 38 is provided at an extended end portion wherein the connection part 38 is outwardly bent.
The connection members 32 are widened in an outer direction of the rim and are slanted at a certain slope. A plurality of reinforcing ribs 40 are formed in an inner surface of the connection member in a longitudinal direction. Here, the reinforcing ribs 40 are preferably connected with the partition plate 36 of the base frame for thereby achieving an enhanced reinforcing function with respect to the embankment blocks.
A connection hole 42 is provided in the connection part 38 of the connection member 32 for connecting the connection parts 38 each other in such a manner that the connection parts 38 of the same embankment block, in which the connection members 32 are opposite to each other, are abutted and overlapped for thereby horizontally connecting the same.
In the connection member 32, both sides of the front end of the connection part 38 are cut-away part by a certain width in such a manner that the connection parts 38 of the connected same embankment blocks are abutted with each other or are overlapped in multiple layers, so that the connection parts 38 are provided on the same height as the connection hole 42. A guide part 44 is formed at a portion in which the connection member 32 and the connection part 38 meet each other, so that the front end of the cut-away part connection part 38 is overlapped with the connection part 38 of the same embankment block.
An engaging protrusion 46 or an engaging hole 48 is formed in a lower surface of the connection part 38 of each connection member 32 for thereby being selectively engaged with the lower surface of the connection part 38 of the same embankment block. For example, in the present embodiment of the present invention, an engaging protrusion 46 is formed in the connection part 38 of one side formed about a diagonal line along four connection members 32 extended from the base frame 30, and an engaging hole 48 is formed in the connection part 38 of the other side.
FIGS. 3 and 4 are views illustrating an example of the engagement of the embankment blocks according to the present invention. The same embankment blocks in which the connection members 32 are opposite to each other are connected using an engaging member 50 in such a manner that the connection parts 38 are abutted with each other. At this time, the engaging protrusions 46 and the engaging holes 48 of the connection parts 38 are first engaged before the embankment blocks are connected using the engaging members 50.
Here, the engaging shoulder 50a is formed at both ends of the engaging member 50 wherein one end of the same is caught by an outer rim part of the connection hole 42, and the other end passing through the other side is widened and caught by the outer rim part of the connection hole 42 of the other side as the corresponding connection members 32 are inserted into a pair of the connection holes 42 that are at the same height in closely contacting state. A cut-away part 50b elastically cut-away in a longitudinal direction is formed at the center of the other end passing through the other side.
In addition, the widened end portion of the engaging member 50 is contracted for escaping the engaging member 50 engaged to the connection hole 42 and is pushed in the reverse direction for thereby releasing the engagement.

In the embankment blocks according to the present invention, the spaces formed in the blocks and filled with soil communicate with upper, lower, left and right sides in the same manner as the conventional embankment blocks. The soil is filled therein and is combined with other soil for thereby forming one lump, so that the embankment blocks are buried in a state that blocks and soil are integral with each other. Therefore, the buried state of the blocks is hard and stable. The soil is not lost and destroyed after a long time period. In particular, the spaces filled with soil communicate with upper, lower, left and right sides, stems or roots of plants can spread in the upper and lower directions as well as the left and right directions through the spaces, so that plants can naturally grow. The buried state of the blocks becomes more stable by the stems and roots of plants growing in the above manner.
In addition, water plants capable of purifying water may be planted in the portion submerged under water for thereby effectively purifying water. Since the blocks are formed of waste plastics, the resource is saved, and the fabrication cost is low. Economical fabrication is achieved.
