A revetment block for preventing the loss of fertile soil is provided to make vegetation easy and to prevent the loss of fertile soil by piling up blocks to cross each other not to be moved vertically and horizontally and forming a vegetation space widely. A revetment block for preventing the loss of fertile soil comprises: unit blocks(10) arranged to intersect vertically to form many block lines(30,31), and composed of a lower structure formed in a rectangle, a horizontal projection formed on the lower structure to project horizontally, a pair of vertical projections formed to intersect with the horizontal projection and spaced out at regular intervals, and a pair of fixing holes(15) penetrated from the front to the rear of the lower structure and fitted with a connection member and spaced out at regular intervals; and space control blocks(11) arranged in spaces which are formed on both ends of the block line to fix the horizontal length of the block lines equally and not to form block lines projected after construction, and composed of a lower structure formed in a square, a horizontal projection projected horizontally on the lower structure, a vertical projection formed vertically by intersecting the center of the horizontal projection, and a fixing hole penetrated from the front to the rear of the lower structure and fitted with the connection member. The unit block and the space control block are connected with each other using the connection member, the lower structures of the unit block and the space control block are made with porous dry concrete to make plants such as lawn or wild plants absorb moisture and root easily after soil dressing and provided with many through holes to guide plants having large roots take the roots on the ground under the lower structure, and a vegetation space(20) of the unit block and the space control block is filled with gravel or stones to prevent the loss of fertile soil against water. |
