Description

Wave dissipating block, Structure for revetment and breakwater applied with the block, and Construction method for the structure}

The present invention relates to a sofa block, a shore or breakwater structure using the same, and a construction method thereof, and more specifically, it is constructed on a shore or a breakwater, etc. By controlling the amount of overtaking as well as protecting the shoreline or breakwater, it is possible to assemble it in a fit-to-fit method without the need for a separate fixing member. It relates to a sofa block that can reduce the construction process, simplify work, improve maintainability, and secure economic feasibility by reducing raw materials, a shore or breakwater structure using the same, and a construction method thereof.

In general, the shore or breakwater is protected by covering the slope of the shore or breakwater to prevent erosion and scouring due to the wave force that comes constantly. Accordingly, recently, as an alternative to that, the factory mass-produced blocks for installing the slopes of the shore or breakwater of a predetermined size and shape, and covering the slopes of the shore or breakwater with such a shore or breakwater coating block to Erosion and scour prevention and the exterior of the shore or breakwater have been constructed in an orderly manner.

As a prior art, in Patent Document 1, in a prefabricated lakebank for masonry of concrete forming blocks, the foundation stage is formed by laying sandstone with a certain thickness, and a hollow block is mounted on the slope of the shore, but the hollow block is placed at a constant height at the upper end. After separating the side wall of a certain thickness having the protruding protrusion by a certain distance, a partition of a certain thickness is vertically spaced between the side wall and the side wall, and a plurality of stages are addressed to provide a gap, and a certain amount is provided at the lower end of the gap. Filling the rock of the stone and laying the small-grained rock on the upper surface along the slope, and inserting a step block having a step shape of a certain size, this step block has a certain thickness and a predetermined slope at the bottom, and the upper part has a plurality of steps of the staircase, and at a certain distance in the middle part of the intermediate step part, a rectangular lifting hole inserting hole is drilled, and the gap between the gap and the step block is made by inserting a telescopic plate of a certain size. The assembly structure of the shore is disclosed.

However, in the revetment structure such as Patent Document 1 described above, in order to protect the structure by treating the covering block and the sofa block as separate components in order to prevent the destruction of the structure due to the waves that invade moisture, There was a problem in that it caused a complicated construction process such as leveling the cladding stone and mounting the intermediate cladding block, which caused a decrease in construction quality and an increase in construction cost.

In addition, in the conventional sofa block, it is difficult to control the rising height and the amount of overshoot due to the induction of wave rising during covering, and to solve this, it is possible to control the overshoot by reducing the wave rising phenomenon. There was a problem in that a separate sofa block is needed more or additional construction occurs.
