  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention.

  In the present invention, a large number of processed log materials 2 in which a side surface 2A is formed by machining are formed on the flat front surface 1A of the retaining wall 1 without providing a concave portion for log fitting or the like. Are arranged side by side so as to cover substantially the entire surface of the flat front surface 1A, and the processed log materials 2 are arranged on the front side of the processed log materials 2 arranged in parallel. The processed log 2 disposed in the direction orthogonal to the length direction is in contact with the side surface 3A of the presser log 3 having the same structure, and the presser log 3 and the processed log 2 are fixed to each other. 4, the pressing log 3 and the processed log 2 are fixed to the flat front surface 1 </ b> A of the earth retaining wall 1 by the fixture 4.

  Similarly to the above-mentioned Patent Document 1, the processed log material 2 uses a log material that is cut down when forming a retaining wall that has been treated as an unnecessary waste material until now. The processed log material 2 can be simply configured simply by forming.

  Further, the processed log material 2 and the presser log material 3 covering substantially the entire front surface 1A of the retaining wall 1 are formed by the fixture 4 through which the processed log material 2 and the presser log material 3 are penetrated. Since it is fixed to the flat front surface 1A, this fixing structure can be easily designed and fixed, and the fixing work can be easily performed. The fixing log 2 and the presser log 3 with this fixing structure have high fixing strength and are fixed with high strength. The processed log 2 and the presser log 3 reinforce the concrete block A itself, so that an excellent earth retaining action is exhibited, and at the same time, the log is placed on the front surface of the flat front surface 1A of the retaining wall 1A. A good landscape with a natural feeling will be revealed.

  In addition, since the retaining wall concrete block A can be an ordinary general-purpose retaining wall block, the flat front surface 1A of the retaining wall 1 is not provided with a log fitting recess and the like. Since the processing log material 2 has the same structure as the processing log material 2, it is not necessary to prepare the pressing log material 3 having a different structure separately. By preparing a large number of processing log materials 2, the processing log material 2 is used as a pressing log material. Since it can be used in common with No. 3, it becomes a concrete block for earth retaining with extremely excellent practicality.

  Further, for example, the processed log material 2 is formed with a pressing flat surface 2B on the opposite side of the side surface 2A, and a plurality of processed log materials arranged in parallel on the flat front surface 1A of the earth retaining wall 1. 2, the side flat surface 3 </ b> A of the presser log 3 disposed in a direction perpendicular to the length direction of each processed log 2 is brought into surface contact with the presser flat surface 2 </ b> B. The side flat surface 3A of the log 3 for contact comes into contact with the flat surface 2B for pressing of the processed log 2 so that the presser log 3 presses and fixes the processed log 2 more reliably. Therefore, a further excellent reinforcing action by the respective log members 2 and 3 can be obtained.

  Further, for example, the processed log 2 is formed with a parallel flat surface 2C having a surface direction in a direction substantially orthogonal to the side-by-side flat surface 2A, and a large number of the processed log members 2 are arranged in parallel on the flat front surface 1A of the earth retaining wall 1. If each processed log 2 is arranged so that the flat surfaces 2C for parallel arrangement come into contact with each other, the processed logs 2 can be stably arranged side by side. The parallel work can be easily performed, and the reinforcing effect of the processed log material 2 arranged side by side is further improved, and the processed log material 2 is arranged side by side with almost no gap, so the appearance is further improved. It becomes good.

  Further, for example, the length direction of each processed log 2 on the front side surface of the processed log 2 existing at least at both ends of each processed log 2 arranged in parallel on the flat front surface 1A of the retaining wall 1 The presser log 3 arranged in a direction orthogonal to the above-mentioned flat surface 3 </ b> A is brought into contact with the presser log 3 and the processed log 2, and a fixing tool 4 is passed through the presser log 3. If the presser log 3 and the processed log 2 are fixed to the flat front surface 1A of the retaining wall 1, a large number of processed logs 2 arranged side by side with the presser log 3 at both ends can be satisfactorily pressed. Therefore, the remarkably excellent reinforcing action of the concrete block A by the processed log 2 and the pressing log 3 can be obtained.
