Water and soil conservation method and a retaining wall for performing the same

Abstract

A retaining wall for water and soil conservation use a plurality of stacking retaining plates. 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. The method for performing the water and soil conservation by the wall is also disclosed.

1 . A water and soil conservation method by using a plurality of stacking retaining plates each of which has a plurality of inner protrusion; wherein the protrusions of the lower retaining plate of the stacking retaining plates grab soil at a bottom of the slopeland. 
   
   
       2 . The water and soil conservation method as claimed in  claim 1 , wherein each retaining plate has outer protrusions at an outer side thereof. 
   
   
       3 . The water and soil conservation method as claimed in  claim 1 , wherein the inner protrusion is made of a soft material. 
   
   
       4 . The water and soil conservation method as claimed in  claim 1 , wherein the outer protrusion is made of a soft material. 
   
   
       5 . The water and soil conservation method as claimed in  claim 1 , wherein the retaining plate has a water spout. 
   
   
       6 . The water and soil conservation method as claimed in  claim 1 , wherein each of the four corners of the retaining plate has a notch; as multiple retaining plates are combined together, the notches of the retaining plates will combine together and form as a water spout. 
   
   
       7 . The water and soil conservation method as claimed in  claim 1 , wherein each inner protrusion of the retaining plate has a hole for being inserted by a pillar so as to form with a strong retaining structure against the slopeland. 
   
   
       8 . A retaining wall for water and soil conservation comprising:
 a retaining plate having a plurality of inner protrusions at an inner side thereof.   
   
   
       9 . The retaining wall for water and soil conservation as claimed in  claim 8 , wherein each of the retaining plate has outer protrusions at an outer side thereof. 
   
   
       10 . The retaining wall for water and soil conservation as claimed in  claim 8 , wherein the inner protrusion is made of soft material. 
   
   
       11 . The retaining wall for water and soil conservation as claimed in  claim 9 , wherein the outer protrusion is made of soft material. 
   
   
       12 . The retaining wall for water and soil conservation as claimed in  claim 8 , wherein the retaining plate has water spout. 
   
   
       13 . The retaining wall for water and soil conservation as claimed in  claim 8 , wherein each of four corners of the retaining plate has a notch. 
   
   
       14 . The retaining wall for water and soil conservation as claimed in  claim 8 , wherein the inner protrusion of the retaining plate has a hole.
