PUZZLE TYPE DRAIN PLATE AND METHOD FOR QUICKLY CONSTRUCTING LAWN GROUND USING THE SAME

摘要

The present invention relates a puzzle type drain plate and a method for quickly constructing a lawn ground using the same. A drain plate (10) of the present invention includes a drain passage (12) penetrating the drain plate in the horizontal direction; a plurality of permeability holes (14) communicating with the drain passage; and combined unevenness elements (16, 18) formed on the sides of the drain plate in all directions. The method for constructing the lawn ground using the drain plate includes the steps of grading the surface of the earth including a drainage channel (20) at the edges of a subject ground; assembling drain plates (10) with the graded surface of the earth in all directions to construct drainpipes; coating a drainage coating (80) on the drainpipes; banking rubble stones of over a certain size on the drainage coating; banking sand and an earthy material on the banked rubble stone layer (70); and transplanting or growing lawns on the banked sand and earthy material layer (60).
