FIELD OF THE PRESENT INVENTION 
       [0001]    The present invention relates to a water and soil conservation method and a retaining wall for performing the same, and in particular to a conservation method and arrangement of protection against the soil and rocks of a slopeland. 
       DESCRIPTION OF THE PRIOR ART 
       [0002]    There are a lot of mountain areas but few plain areas in Taiwan. Debris flows happen during heavy rainfall in the mountain area. Because of heights of the mountains and short of rivers, soil and rocks need forest and plant to keep moisture and be retained by. Soil and water conservation is now an important issue after damages and disasters caused by debris flow and deforming of slopeland. 
         [0003]    To prevent the disaster mentioned above, a lot of actions are needed to be carried out in the same time. For example, encouragement to planting and prohibition against hewing and reclaiming is an important fundamental of soil and water conservation. For preventing an instant and accidental disaster, protection to slopeland retaining wall is needed to prevent debris flow invading roads or residential areas. Retaining walls are arranged along mountain roads to passively block the soil and rocks of the unstable slopeland. 
         [0004]    Furthermore, in a prior technique of blocking soil and rocks, it is performed by constructing retaining wall as a barrier to prevent collapse at a mid-slope or a foot of a mountain and the area near a steep slope. However, the prior retaining wall is a plate of wall inserted into a slopeland. The plate structure is simple, weak, and lack of adhesion to the land. When a heavy rainfall comes, the walls are sometimes toppled and collapse with the soil and rocks. 
       SUMMARY OF THE PRESENT INVENTION 
       [0005]    Accordingly, the inventor intends to provide an improved method and structure basis on the motive of research. 
         [0006]    To solve the problem mentioned above, a conservation method and a retaining wall are invented for the purpose of conserving water and soil. A plurality of retaining plates are stacking together. Each of the retaining plate has a plurality of inner protrusions at an inner side thereof. The protrusions of the lower retaining plate of the stacking retaining plates grab the soil at the bottom of the slopeland so as to form a steady retaining structure and method.

         [0015]    Referring to  FIG. 1 , a retaining wall for soil and water conservation is illustrated. The retaining wall  1  includes following components. 
         [0016]    A rectangular retaining plate  11  can be made of concrete. Water spouts  110  are formed on the retaining plate  11  for draining the rainwater of the slopeland. Each of four corners of the retaining plate  11  is formed with a notch  111 . With reference to  FIG. 2 , when a plurality of retaining plates  11  are combined together, notches of the adjacent retaining plates  11  will form as a water spout. An inner side of the retaining plate  11  is formed with a plurality of inner protrusions  112  which are adjacent one by one. An outer side of the retaining plate  11  is formed with a plurality of outer protrusions  113  which are adjacent one by one. The inner protrusion  112  of the present invention can be made of a soft material. For example, a part of waste tire is inserted into the concrete during the forming process of the retaining plate  11  and the waste tire will be fixed to the retaining plate  11  when the concrete is solidified. The retaining plate  11  of the present invention can be manufactured in a factory and be transported to the slopeland. 
         [0017]    The outer protrusion  113  of the present invention can be made of a soft material. For example, a part of waste tire is inserted into the concrete during the forming process of the retaining plate  11  and the waste tire will be fixed to the retaining plate  11  when the concrete is solidified. 
         [0018]    As shown in the drawings, the inner protrusion  112  or the outer protrusion  113  is formed with a hole  114  at a center thereof. The hole  114  is a partial round hole in the center of the waste tire divided by the retaining plate  11 . The hole  114  can also be a entirely round hole of the center of the waster tire.
