SAWTOOTH TYPE-SUBMERGED BREAKWATER BLOCK FOR PREVENTING COASTAL EROSION

摘要

The present invention relates to a sawtooth type-submerged breakwater block for preventing coastal erosion which is a coastal erosion prevention means in a new operation type. The present invention is provided to effectively and surely prevent coastal erosion caused by the movement of sea water through a complex functional effect obtained by combining a wave absorbing effect (wave dispersion effect) to disperse wave by properly dispersing and offsetting the pressure of sea current moving with a high speed and a nourishment effect to structurally prevent the loss of sand caused by the movement of sea water. The sawtooth type-submerged breakwater block includes a block body part, which includes a block tunnel part of a semi-circular section formed along the longitudinal direction, a plurality of body sawtooth protrusions with a sawtooth-shape, which protrude from the outer surface along the longitudinal direction, and sea water dispersion grooves formed between the body sawtooth protrusions, and a block bottom part having bottom supporting protrusions, which protrude from both lower sides of the block body part in order to be safely seated on the sea bottom and form a bottom supporting portion along the longitudinal direction of the block body part, wherein a plurality of sea water introducing holes pass through the sea water dispersing grooves in the lower part of the front portion of the block body part, which is directed toward the sea side in order to allow sea water, which is introduced from the sea side and pass through the holes, and a plurality of sea water discharging holes pass through the sea water dispersing grooves in the upper part of the rear portion of the block body part, which is directed toward the seashore in order to allow the sea water introduced into the block tunnel part through the sea water introducing holes to be discharged toward the seashore while offsetting the pressure of the sea water.;COPYRIGHT KIPO 2015
