Description
본 고안은 수중구조물 보수장치에 관한 것으로서, 보다 상세하게는 하천 등에 부설되는 교각과 같은 수중구조물의 손상된 부분을 용이하게 보수하여 견고하고 안정적인 보수효과를 발휘할 수 있도록 된 수중구조물 보수장치에 관한 것이다.The present invention relates to an apparatus for repairing an underwater structure, and more particularly, to an apparatus for repairing an underwater structure capable of easily repairing a damaged part of an underwater structure such as a pier attached to a river, etc., to exhibit a solid and stable repair effect.
일반적으로 수중에 부설된 교각 등은 흐르는 물에 의한 세굴이나 부식 등과 같은 여러 장애 요인에 의해 국부적으로 손상이 발생하게 된다. 이러한 손상은 구조물의 안전에 치명적이므로 보수가 필요하게 된다. 종래에는 손상된 부분을 보수하기 위해 거푸집 등의 보수장치를 수중구조물 둘레에 부설하고 이 거푸집 내로 팽창성 콘크리트 등 보강재를 채워 경화시키는 방법을 이용하였다.In general, the piers, etc. placed in the water is locally damaged by various obstacles such as scour or corrosion caused by running water. These damages are critical to the safety of the structure and require repair. Conventionally, in order to repair damaged parts, a repair device such as a formwork is placed around the underwater structure, and a method of hardening by filling a reinforcement such as expandable concrete into the formwork is used.
그런데, 상기 보수장치를 이용하는 방법은 보수 후 이전 구조물보다 두터운 구조물이 생기게 되고, 이에 따라 물의 흐름에 변화를 주어 유속이 빨라지거나 방향이 바뀌게 되어 새로운 세굴이 발생하는 등 장애 요인이 재차 발생되므로 의도한 보수효과를 발휘하기 어려운 문제점이 있었다.However, in the method using the repair device, after the repair, a thicker structure is formed than the previous structure, and accordingly, a change in the flow of water causes a flow rate to be changed or the direction is changed so that a new scour occurs. There was a problem that is difficult to exert a conservative effect.
본 고안은 전술한 바와 같은 문제점을 해결하기 위한 것으로서, 본 고안의 목적은 하천 등에 부설되는 교각과 같은 수중구조물의 손상된 부분을 용이하게 보수하여 견고하고 안정적인 보수효과를 발휘할 수 있도록 된 수중구조물 보수장치를 제공하고자 하는 것이다.The present invention is to solve the problems as described above, the object of the present invention is to repair the damaged parts of the underwater structure, such as the pier to be installed on the river easily repairing the underwater structure to be able to exert a solid and stable repair effect Is to provide.

이하, 본 고안의 바람직한 실시예를 첨부한 도면에 의거하여 설명하면 다음과 같다.Hereinafter, described with reference to the accompanying drawings, preferred embodiments of the present invention is as follows.
도 1은 본 고안에 따른 수중구조물 보수장치의 사용상태 정면도이고, 도 2는 도 1의 측단면도이다. 본 고안에 의한 수중구조물 보수장치는 손상부위(10)에 설치되는 밀폐부재(20)와, 그 일단부가 이 밀폐부재(20)에 연결되는 주입관(30)과, 밀폐부재(20)에 구비되는 배출수단(40)으로 구성된다.1 is a front view of a state of use of the underwater structure repair apparatus according to the present invention, Figure 2 is a side cross-sectional view of FIG. The apparatus for repairing an underwater structure according to the present invention includes a sealing member 20 installed at a damaged part 10, an injection pipe 30 connected to one end thereof to the sealing member 20, and a sealing member 20. It is composed of a discharge means (40).
상기 밀폐부재(20)는, 도 2에 도시된 바와 같이, 대략 강판으로 되어 소정 위치에 주입부(22) 및 배출부(24)가 형성되는데, 수중구조물(5)의 손상부위(10)에 설치될 때 이 주입부(22)가 하측으로 향하고 배출부(24)는 상측으로 향하도록 한다. 상기 주입관(30)은 스틸파이프나 플렉시블한 튜브 혹은 호스 등을 포함하는 것으로서, 그 일단부가 상기 주입부(22)에 연결되어 상기 손상부위(10)에 연통되고 타단부는 수면 위로 연장되어 보강재공급부에 연결된다. 상기 배출수단(40)은 대략 관체로 되어 그 일단부가 상기 배출부(24)에 연결되고 타단부는 수면 위로 연장되어 고정된다.As shown in FIG. 2, the sealing member 20 is formed of an approximately steel plate, and an injection part 22 and an discharge part 24 are formed at predetermined positions, and the damaged part 10 of the underwater structure 5 is formed on the sealing member 20. When installed, the injection section 22 faces downward and the discharge section 24 faces upward. The injection pipe 30 includes a steel pipe, a flexible tube or a hose, and one end thereof is connected to the injection part 22 to communicate with the damaged part 10 and the other end extends above the water surface to reinforce the material. Connected to the supply. The discharge means 40 is substantially tubular, one end of which is connected to the discharge part 24 and the other end extends above the water surface and is fixed.
상기 밀폐부재(20)는, 도 1 및 도 2에 도시된 바와 같이, 수중구조물(5)의 손상부위(10)를 깎아내어 칩핑부(12)를 형성하고 그 주변에 앵커볼트(25)와 너트(26)를 이용하여 고정설치된다. 앵커볼트(25)와 밀폐부재(20) 사이에는 칩핑부(12) 둘레부를 감싸도록 패킹부재(28)을 설치하게 되는데, 이 패킹부재(28)은 밀폐부재(20)가 부착되었을 때, 칩핑부(12)로 물이 침투되지 않도록 한다.As shown in FIGS. 1 and 2, the sealing member 20 forms a chipping part 12 by scraping off the damaged part 10 of the underwater structure 5 and the anchor bolt 25 and the periphery thereof. It is fixed by using the nut 26. The packing member 28 is installed between the anchor bolt 25 and the sealing member 20 so as to surround the chipping part 12. When the sealing member 20 is attached, the packing member 28 is chipped. Prevent water from penetrating into the part 12.
상기 주입관(30)을 통해 팽창성 콘크리트 등의 보강재가 주입되면 칩핑부(12)의 하부에서부터 채워지게 되며 이 칩핑부(12) 내부 공간의 물과 공기는 채워지는 팽창성 콘크리트의 압력에 의해 상부로 밀려가면서 상기 배출수단(40)을 통해 수면위나 외부로 배출된다. 이렇게 칩핑부(12)에 완전히 채워진 보강재가 경화된 후 상기 보수장치는 철거되지만 해당 지역의 유속과 구조물의 종류 등을 고려하여 철거되지 않을 수도 있다.When the reinforcing material such as expandable concrete is injected through the injection pipe 30, the reinforcing material such as the expandable concrete is filled from the bottom of the chipping part 12, and the water and air in the space inside the chipping part 12 are moved upward by the pressure of the expandable concrete. While being pushed is discharged to the surface or the outside through the discharge means 40. After the reinforcing material completely filled in the chipping part 12 is hardened, the repair device is dismantled, but may not be dismantled in consideration of the flow rate of the region and the type of the structure.
따라서, 상기 수중구조물 보수장치는 손상부위(10)의 보수 후에도 그 보수된 부분의 크기나 부피 등의 변화가 거의 없어 유속의 변화 등에 따른 2차 세굴 등 장애요인이 제거되므로 견고하고 안정적인 보수효과를 기대할 수 있다. 또한, 종래 보수장치에 의하면 손상부위분에 보강용 콘크리트를 주입할 때 수중으로 유출되는 콘크리트가 많아 수중 오염의 원인이 되었으나, 상기 수중구조물 보수장치는 콘크리트의 유출이 없으므로 수중환경오염을 방지할 수 있다. 그리고, 다량의 자재가 소요된 종래의 보수장치에 비하여 상기 수중구조물 보수장치는 자재의 양이 줄어들어 재료비 등과 같은 코스트가 절감될 수 있다.Therefore, the underwater structure repair apparatus has a hard and stable repair effect since the obstacles such as secondary scouring due to the change of the flow rate are eliminated because there is almost no change in the size or volume of the repaired portion even after repair of the damaged part 10. You can expect In addition, according to the conventional repairing device, when the reinforcing concrete is injected into the damaged part, a lot of concrete leaks into the water, causing water pollution. However, the repairing device for the underwater structure can prevent pollution of the underwater environment since there is no concrete leakage. have. In addition, the underwater structure repair apparatus may reduce costs such as material costs as compared to the conventional repair apparatus that requires a large amount of materials.
이상에서와 같이 본 고안에 의하면, 상기 수중구조물 보수장치는 손상부위의 보수 후 그 보수된 부분의 부피나 두께 등의 변화가 거의 없으므로 안정적이고 견고한 보수효과를 발휘할 수 있고, 보강재가 수중으로 유출되지 않으므로 환경을 보호할 수 있으며, 자재비가 줄어들어 코스트가 절감될 수 있는 장점이 있다.As described above, according to the present invention, the underwater structure repair apparatus can exhibit a stable and robust repair effect since there is almost no change in the volume or thickness of the repaired portion after repairing the damaged portion, and the reinforcement is not leaked into the water. Therefore, the environment can be protected, and material costs can be reduced to reduce costs.
