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.
