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 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. Prior to the connection, a through hole 6 is formed at the position leading to the connection opening 13 perpendicular to other two underdrainage blocks 1 and 1' and 1 and 1' inserted into each other in the direction of aligning the two remaining connection openings 11 and 12 facing each other. The underdrainage blocks are connected together in such a manner that the through hole 6 communicates to the block 1" on the side of the connection opening 13 perpendicular to the hole 6.
