PURPOSE: A gravity type quay wall structure using together with a porous construction method is provided to construct a quay wall with low expenses and to keep the stability of a quay wall to bear external force. CONSTITUTION: The gravity type quay wall structure(1) using together with a porous construction method comprises the steps of piling up many hollow blocks(4) provided with a female key(13) and a male key on the top of a riprap foundation(3), filling up an inner space of the hollow block(4) with riprap(5), forming a subsidence part(7) on the top of right or left walls of the hollow block(4a), forming a lower foundation(1a) while filling up riprap(5) up to the half of the subsidence part(7), and placing an intermediate block(1b) on the top of the riprap(5) of the lower foundation(1a).
