Composite rockfill submerged dike

Abstract

The invention provides a composite rockfill submerged dike. The composite rockfill submerged dike comprises three rows of supporting piles, three rows of longitudinal girders, a plurality of rows of beams, first rubbles and a wave absorption plate, wherein each longitudinal girder is fixedly arranged at the top of each row of supporting piles; the beams are arranged among the longitudinal girders, the end parts of the beams are fixedly connected with the longitudinal girders, and the beams and the longitudinal girders form a planar frame structure used for supporting the wave absorption plate which is provided with a plurality of through holes and arranged on the planar frame structure; and the first rubbles are piled among the supporting piles, and the wave absorption plate is arranged above the first rubbles. The piled stones stacked by the first rubbles can effectively take a wave absorption effect at a lower water level, and the wave absorption plate can effectively take a wave absorption effect at a high water level so as to provide effective shield for a coastline and improve the water body exchange capability of the composite rockfill submerged dike.

Description

technical field [0001] The invention relates to a breakwater for port and coastal engineering, in particular to a composite rock-fill submerged embankment. Background technique [0002] Rockfill submerged embankment is a commonly used coastal protection structure, which is submerged underwater and can emerge from the water when the water level is designed to be low. When the submerged embankment comes out of the water, it needs to bear a large wave load, and the weight of the armor structure needs to be increased. In addition, after the water comes out, it will affect the exchange of water inside and outside the shelter area. If the submerged embankment has a large submerged depth and remains submerged at low water levels, the structural stress is small and the investment is low; but at high water levels, because the submerged embankment is deeply submerged, the wave energy is mainly concentrated in the free Near the water surface, the submerged embankment cannot provide ef...
