An assembly block for a bank is provided to prevent the scour and inundation of a river by high drainage pressure if flowing water is swollen by a heavy rain at a bank for a river or a reservoir, and to be used for a bank to drain off water in the appropriate quantity. An assembly block for a bank is formed by forming an inside space(36) with an upper side(49), and inside and outside walls(24,25), forming an inlet port(57) on the upper part of the inside wall, fixing a piston to the outside wall, assembling a removal plate to one side of a fixing bar assembled and connected to a support bar fixed to the upper side and connecting the fixing bar with a shaft of the piston, so that waste suspended on the inlet port is swept away by the reciprocating motion of the removal plate. |
