Claim:
An ocean water drawing system comprising: a first well adapted to be disposed adjacent to a seashore; a first working tunnel disposed underground and extending between said first well and the seashore, said first working tunnel being isolated from said first well and the ocean, and haying an end segment distal from said first well and proximate to the seashore; a first pipeline unit including a primary pipeline disposed in said first working tunnel, and having one end extending sealingly into said first well and the other end extending through said end segment of said first working tunnel and into the ocean so as to permit ocean water to flow into said first well through said primary pipeline; and an access tunnel isolated from said first well and extending downwardly from a ground surface to intersect said first working tunnel so as to communicate spatially with said first working tunnel and so as to permit access into said end segment of said first working tunnel for operation and maintenance of said primary pipeline; wherein said end segment of said first working tunnel defines a working chamber therein, said working chamber being partitioned so as to form a plurality of compartments which are isolated from each other, each of said compartments being defined by a compartment-defining wall that has a compartment entrance and that is provided with a compartment gate for opening and closing said compartment entrance, said primary pipeline including a main pipe and a plurality of branch pipes, each of which extends from an end of said main pipe through a respective one of said compartments and into the ocean, and each of which has a first section disposed in the respective one of said compartments and provided with a first control valve for blocking and unblocking ocean water flowing therethrough.
