Description

A sofa block, an offshore structure using the same, and a construction method thereof

The present invention relates to a sofa block, and more particularly, to a sofa block provided with a vertical angle in the front and a horizontal angle connected to the vertical angle in the rear.

A sofa block is a unit block that is regularly (static) or irregularly mounted (hard loading) in order to dissipate the energy of seawater and waves to prevent damage to ports or offshore structures due to seawater and waves.

The widely known so-called tetrapods are mainly used as blocks with a small tonnage, and so-called C-Rock (refer to Korean Patent Publication No. 991914) and Dolos (refer to Korean Patent Publication No. 1400295) are mainly used for blocks with a large tonnage.

Among them, the sofa blocks such as Searock and Dolos have a body extending in the front-rear direction, vertical angles extending up and down from the front end of the body, and horizontal angles extending left and right from the rear end of the body. . And, when mounting such a sofa block on the slope, the horizontal angle part is mounted on the upper side of the slope, and the vertical leg part is arranged so that the sofa block is placed on the lower side of the slope and mounted. And the body between the horizontal angle part and the vertical angle part is such that the horizontal leg parts of the two sofa blocks mounted at the lower end are placed on the adjacent part.

However, according to this type of mounting method, only the body of the sofa block mounted on the upper end is supported by other sofa blocks mounted on the lower end, and the vertical angle part of the sofa block mounted on the upper end is at the lower end. There is a problem that the mounting becomes unstable because it is in a floating form without being supported by other mounted sofa blocks.

However, if the vertical angle part of the sofa block mounted on the upper end is extended longer in the front-rear direction to be supported on the other sofa block mounted on the lower end, the moment applied to the body increases and the body may break. There was a problem.

In addition, in the sofa block of this type, the vertical angle part takes a posture lying down considerably in the inclination direction of the slope, and a problem arises that the vertical angle part rides the vertical part and the wave overtake occurs.

The present invention has been devised to solve the above problems, and it is intended to provide a sofa block having a body, a horizontal and vertical angle, and a sofa block capable of stable mounting and preventing over-wave.

In addition, the present invention is to provide a sofa block that does not cause damage to the body.
