Description

Breakwater Head structure {The cephalic structure of a breakwater}

The present invention is a port area, various vessels anchored in coasts or docks, etc. are severely shaken by blue to prevent the docking facilities or ships from colliding with the ships to damage the facilities and ships in the harbor to ensure safe anchoring of the vessels. In order to maintain the calmness, the facility that is constructed to intercept the blue waves that are pushed towards the coast is a breakwater, and the breakwater usually has its tip. The tip is called breakwater tofu. It is easy to be damaged due to endless waves of waves from the side and side, so to minimize the damage, it is necessary to have a gentle slope so that the gradient is 1: 3 for the safety of the design. Weakening Wave Power by Tetrapod Bones To have to build the structure of the breakwater head.

Conventional breakwater (1) of a predetermined length, which is constructed at a pier where a large and small vessel enters or leaves a port, must have an opening through which the vessel can enter and exit at a suitable position for entering and exiting the vessel. In order to protect the head 2 from blue as the head 2 of (1), the inclination of the head inclined surface is set at a gradient of 1: 3 for the safety of design, and is attached with reference to the breakwater (1) tip. FIGS. 1 and 2 As shown by the dotted line and the two-dot chain line as shown in the figure, the construction of a large area in the shape of a fan is inclined. Tent of the inclined surface 2a of the head 2, which is gently inclined by the bottom of the ship submerged in the waterline below the ship's waterline when the ship enters and exits between the heads of the breakwaters 1 at both ends. There is a case that a very dangerous accident occurs that collides with Laford (3) and damages the bottom of the ship. Therefore, it is required to make a firm breakwater head (2) while minimizing the slope of the head (2) as much as possible. Bar,

In constructing the head 2 of the breakwater 1 according to the present invention, a plurality of circular arc hollow blocks 3, 3a having upper and lower surfaces opened at the lowermost end of the breakwater head 2 installed in the sea bottom 7. (3b) and (3c), the lower foundation barrier wall (6) which forms a female key (4) and a male key (5) in each of the bowls, and combines the female key (4) and male key (5) to form a single horseshoe. ) Is installed flat on the sea bottom (7) and filled with the sandstone (8) inside each arc hollow block (3) (3a) (3b) (3c), and each arc hollow block (3) (3a) (3b). (2c) the two mating surfaces having an outer circumferential surface coinciding with the horseshoe-shaped inner arc surface 6a of the lower foundation blocking wall 6 to be (3c) are connected at right angles, the other end of which is a 1/4 arc and becomes a main wall of constant height. Two fan-shaped hollow blocks (9) (9a) having a top and bottom opening and a hollow inside are treated in a semicircular shape, and a female key (4a) and a male key (5a) are formed on the abutment surface so that the female key (4a) and male key (5a) are formed. Inserted The two flat hollow blocks 9, 9a are treated with arcs, and the circular arc surfaces 10, 10a of the flat hollow blocks 9, 9a are inclined at a constant angle (about 15 °). The fan-shaped hollow blocks 9 and 9a are stacked in a plurality of stages at a required height, but a plurality of protrusions 11 and 10 are formed on the outer circumferential surface of the fan-shaped hollow blocks 9 and 9a to have a predetermined size. As the number is large, only one "11" is indicated in the drawing) in a zigzag fashion so as to deviate horizontally from each other, and the fan-shaped hollow blocks 9 and 9a are located on the back of the fan-shaped hollow blocks 9 and 9a. Connect the rectangular hollow blocks 12 and 12a that are coincided with each other, but each of the mating surfaces of the fan-shaped hollow blocks 9 and 9a and the quadrangular hollow blocks 12 and 12a respectively has a female key 4b and a male key ( 5b) is formed so that each of the female keys 4b and the male keys 5b are inserted into each other, and the top-shaped hollow blocks 9, 9a and the quadrilateral hollow blocks 12, 12a are stacked on top. Each corner welding portion is formed with a circular space portion 13 having a predetermined diameter, and the inside of each of the fan-shaped hollow blocks 9 and 9a and the quadrilateral hollow blocks 12 and 12a fills the sandstone 8a and is located at the top. On the top surface of the stacked hollow hollow blocks (9) (9a) and the quadrilateral hollow blocks (12) (12a), the upper concrete cap 14 is placed in a semi-circular shape, but the circular space portion 13 is located at the center of the concrete cap 14.
