Abstract

PURPOSE: Breakwater cap concrete structure for blocking overtopping waves is provided to minimize the overtopping of waves when such high waves as a typhoon strike, at the minimum construction cost. CONSTITUTION: In building a breakwater(1) of an area having relatively low wave height, a wave-dissipating structure(10) is connected simultaneously with a cap concrete form(2) in placing the cap concrete form. The wave-dissipating structure has a rear wall(11) and a semicircular wall body(12) vertically disposed to the front of the rear wall. The semicircular wall body is connected with the right and left points of the rear wall. Vertical projected rods(13) are installed to the front of the semicircular wall body at regular intervals. Water-passing holes(14) are bored in the whole surface of the semicircular wall body except for the vertical projected rods. Two fixed support rods(15) are oriented on the rear of the rear wall. The front-end portion of the fixed support rods forms fixing projections(16) with thickness thicker than the thickness of the fixed support rod.

Description

Breakwater capconcrete structure for overflow waves interception

The present invention relates to a structure of a cap concrete provided at the top of a breakwater body. The breakwater structure is generally classified into a body structure such as a sandstone breakwater, a caisson breakwater (upright breakwater), and a hybrid breakwater. The top of the cap concrete can be used as a traffic road by finishing it with cap concrete, which is cast in place of concrete.

However, in the case of the area where the small wave of less than 5M is mainly applied, the site is equipped with a cap concrete having a rectangular cross section of a predetermined height, which is a simple form, and when the high blue waves due to the typhoon in summer, the cap concrete of the breakwater As blue waves enter the inland sea, they cause damage to ships and harbors targeting small ships by damaging ships and various dock facilities anchored in the inland sea. There is a problem of economic waste to construct a breakwater with a high system costing a lot of construction cost to block.

The present invention relates to the structure of the breakwater, which keeps the calmness of the inner sea at all times to protect the vessels and harbor facilities safely, and to block them when high waves such as typhoons occur, but it requires only minimal construction cost to block the wave. Based on the accompanying drawings, the present invention enables the construction of a breakwater with a cap concrete structure of a breakwater, which enables the breakwater to be described as follows.

In constructing the structure of the breakwater (1) cap concrete (2) of the known breakwater (1), the sofa structure (10) is separately formed by molding the cap concrete (2) to be cast at the same time when the cast structure, but the sofa structure (10) The structure of the back wall 11 is provided with a predetermined height and the front of the rear wall 11 is provided with a semi-circular wall (12) vertically connected to the left and right ends of the rear wall (11) and the front of the semi-circular wall (12) A plurality of vertical protrusions 13 are protruded in a state spaced apart by a predetermined distance, and a plurality of seawater passing holes 14 of a predetermined diameter are installed on the entire surface of the semicircular wall 12 except for the vertical protrusions 13. On the back of the rear wall 11, two fixed support sections 15 are oriented to protrude, but the front ends of the two fixed support sections 15 increase the frictional resistance to increase the fixed support force so as to increase the fixing support section ( 15) Sofa structure that is formed thicker than the thickness and made of this structure When the cap concrete (2) is cured by connecting the cap concrete (2) at the same time when the cap concrete (2) is poured, the fixing support section (15) of the sofa structure (10) is fixed and fixed together with the cap concrete (2) body. Will be.

When the sofa structure 10 separately molded and manufactured as described above is poured into the concrete while the fixed support section 15 of the sofa structure 10 is poured into concrete, the blue wave of high digging due to typhoons etc. Even though it is hit by the sofa structure (10), the blue waves can be minimized. Blue waves entering the seawater hole (14) installed on the sofa structure (10) hit the rear wall (11) and reflect, It is dissipated and the sofa structure 10 is a semi-circular shape to increase the contact surface of the blue to reduce the wave pressure and to build a breakwater having a function to sofa the blue wave of high digging with a low construction cost.

Claims (1)

In constructing the breakwater (1) in the region where the wave height is relatively low, the sofa structure (10) is molded and connected at the same time when the cast concrete is cast, but the structure of the sofa structure (10) is the rear wall ( 11) is provided at a predetermined height, and the semicircular wall 12 connected to the left and right ends of the rear wall 11 is vertically provided on the front surface of the rear wall 11, and a plurality of vertical protrusions are formed on the front surface of the semicircular wall 12. 13) is projected to be spaced at a predetermined distance, and a plurality of seawater hydraulic holes 14 having a predetermined diameter are laid on the entire surface of the semi-circular wall 12 except for the vertical protrusion 13, and the rear wall 11 is rear Orientation protrusions of the two fixed support intervals 15, but the front end portion of the two fixed support intervals (15) is formed so thicker than the thickness of the fixed support interval (15) of the fixed support interval (15) sofa structure (10) ) When cap concrete (2) is poured at the same time Breakwater structure for Overtopping cap concrete block characterized by.
