Method of construction for draining the ground and the like

Abstract

A method of construction for draining the ground in which water rarely permeates into the underground, and water is drained from the ground in a short period of time and dried. The method includes the steps of: as shown in FIG. 3 , digging the circumference of the surface of ground requiring draining of the ground ( 1 ) to form a waterway ( 3 ); building up a central portion of the surface of ground within the waterway ( 3 ) and carrying out leveling by rolling with roller to form a foundation bed ( 2 ); covering the whole surface of the foundation bed ( 2 ) with corrugated plates of plastics ( 7 ) having convex portions ( 18 ) and concave portions ( 19 ); laminating crushed stones; covering the crushed stones ( 8 ) with the ground surface earth ( 9 ), and causing water permeated into the ground surface earth ( 9 ) due to rainfall or the like to flow into the peripheral waterway ( 3 ) from the concave portions ( 19 ) of the corrugated plates of plastics ( 7 ) to effect draining.

What is claimed is:  
     
         1 . A method of construction for draining the ground, said method comprising the steps of: digging the earth around the ground requiring drainage of the ground to form a waterway around the ground; heaping up earth on a central portion of the ground within the waterway and grading the heaped ground with a roller to form a foundation bed of the ground; covering the whole surface of the foundation bed with corrugated plates of plastics of which surface comprises a continuous corrugated surface in which a number of convex portions and a number of concave portions are continuous alternately; laying crushed stones on the corrugated plates of plastics; covering the laid crushed stones with the earth to form the surface earth of the ground, and causing water permeated into the surface earth of the ground due to rainfall or the like to accumulate into the concave portions of the plates of plastics and to flow into the waterway from the concave portions of the plates of plastics to effect draining.  
     
     
         2 . The method of construction for draining the ground of  claim 1  wherein a water permeation mat is laid in place of the crushed stones which is laid on the corrugated plates of plastics.  
     
     
         3 . The method of construction for draining the ground of  claim 1  wherein a water permeation mat is interposed between the corrugated plates of plastics and the crushed stones laid thereon.  
     
     
         4 . The method of construction for draining the ground of  claim 1  wherein a water permeation mat is interposed between the crushed stones laid on the corrugated plates of plastics and the surface earth of the ground heaped thereon.  
     
     
         5 . The method of construction for draining the ground of  claim 1  wherein a water permeation mat is interposed between the corrugated plates of plastics and the crushed stones laid thereon, and a water permeation mat is also interposed between the crushed stones and the surface earth of the ground heaped thereon.  
     
     
         6 . The method of construction for draining the ground of any of  claims 1  to  5  wherein a water tank is constructed in the underground of the foundation bed of the ground surrounded by the waterway, and the waterway in the surroundings of the ground is connected to the water tank for storing the water gathered from the surface earth of the ground to the waterway.
