Abstract
PURPOSE: To ensure a smooth flow of drain in the construction by making thoroughly even the drainage channel made up of groups of underdrainage blocks each arranged horizontally.
CONSTITUTION: A connection cover 10 with a shape of T, Y or the like which comprises connection openings 11W13 adapted to connect underdrainage blocks 1W1" as inserted into each other at the ends by a specified length, arranged in three or more ways is used to connect underdrainage blocks in a shape of T, Y or the like. In the connection, the end of the underdrainage block 1" inserted into the connection opening 13 perpendicular to other two blocks is grasped between the ends of the underdrainage blocks 1 and 1' inserted into the remaining two connection openings 11 and 12 facing each other.
