본 발명은 교량 우물통기초의 세굴방지구조에 관한 것으로서, 더욱 상세하게 는 유속이 가장 빠른 부분에 해당되는 교량의 우물통기초 부분에 설치되어 유속에 의한 기초의 침식을 차단하여 시간이 경과함에 따른 교량의 내구성이 저하되는 것을 방지하도록 하는 교량 우물통기초의 세굴방지구조에 관한 것이다. The present invention relates to a scour prevention structure of a bridge well passage foundation, and more particularly, is installed in the well passage foundation portion of the bridge corresponding to the fastest flow rate to block the erosion of the foundation due to the flow rate over time The present invention relates to a scour prevention structure of a bridge well ventilation foundation for preventing the durability of a bridge from being lowered.

도 1에 도시된 바와 같이 교량의 교각(100) 하부에 있는 우물통기초(200)는 시간이 경과함에 따라 흐르는 물의 유속에 의하여 지속적인 침식이 일어나 세굴현상에 따른 세굴부(210)가 생기게 된다. As shown in FIG. 1, the well passage foundation 200 under the bridge 100 of the bridge has a scour portion 210 due to the scour phenomenon due to continuous erosion caused by the flow rate of water flowing over time.

이러한 세굴현상은 일단 진행되는 초기단계에서 빠른 속도로 세굴부(210)가 커지게 되며, 심한 경우에는 철근이 드러나 부식을 가속화시키며, 이를 계속 방치할 경우 교각이 지탱할 무게를 감당하지 못하게 되어 붕괴되는 지경까지 이를 수 있다. This scour phenomenon occurs at a rapid speed in the initial stage once the scour section 210 is large, and in severe cases the rebar is exposed to accelerate the corrosion, if left unattended, the bridge can not bear the weight to support the collapse It can be reached.

따라서 이러한 우물통기초(200)에 발생하는 세굴부(210)를 방지하기 위해 여러 가지 방안이 모색되어 왔고, 우물통기초(200)를 보수 보강하는 여러 방법이 제시되어 왔다.Therefore, various methods have been sought to prevent the scour portion 210 occurring in the well well base 200, and various methods of repairing and strengthening the well well base 200 have been proposed.

그러나, 종래의 보수 보강방법은 대체적으로 세굴부에 콘크리트나 철판을 덧대는 방식이 대부분이었기 때문에 시간이 경과함에 따라 세굴부가 다시 진행되는 문제점이 발생되었다.However, in the conventional repair reinforcement method, the method of adding concrete or steel plate to the scour portion is generally the problem that the scour portion proceeds again with time.

따라서 본 발명은 상기의 제반문제를 해결하기 위해 창출된 것으로서, 그 목적은 우물통기초에 세굴현상이 진행되기 전에 미리 설치하여 유속에 의한 기초의 침식을 차단하여 시간이 경과함에 따른 교량의 내구성이 저하되는 것을 방지하도록 하는 교량 우물통기초의 세굴방지구조를 제공함에 있다. Therefore, the present invention was created to solve the above-mentioned problems, the purpose is to install in advance before the scour phenomenon in the well well foundation to block the erosion of the foundation by the flow rate of the durability of the bridge over time It is to provide a scour prevention structure of the bridge well ventilation foundation to prevent the degradation.

본 발명은 도 2 내지 도 4에 도시된 바와 같이,As the present invention is shown in Figures 2 to 4,

양 가장자리에 수직방향의 결합레일(12)이 형성되고, 일정 원주율로써 원호 형상을 가지며, 습동 이동이 가능한 슬라이더(14)가 설치된 FRP코팅 철판패널(10)을 구비한다. Coupling rails 12 in the vertical direction are formed at both edges, and have an FRP-coated iron plate panel 10 having a circular arc shape with a predetermined circumference and provided with a slider 14 capable of sliding movement.

상기 FRP코팅 철판패널(10)은 다수개가 모여 결합될 때 우물통기초(200)의 직경보다 크되 상기 슬라이더(14)에 의해 상기 우물통기초(200)와 동심원을 이루는 하나의 패널 결합체(1)가 형성된다. The FRP-coated iron plate panel 10 is larger than the diameter of the well well base 200 when the plurality is combined, but one panel assembly (1) concentric with the well well base (200) by the slider (14) Is formed.

또한 상기 패널 결합체(1)를 위한 각 FRP코팅 철판패널(10)의 양쪽 결합레일(12)을 동시에 수용하는 "T" 자형 결합홈(22)을 갖고, 패널의 결합상태를 유지함과 동시에 우물통기초(200)와의 결합오차에 대응하도록 자체탄성력을 갖는 결합 지지틀(20)이 구비된다. In addition, it has a "T" shaped coupling groove 22 for accommodating both coupling rails 12 of each FRP-coated iron plate panel 10 for the panel assembly 1 at the same time, while maintaining the state of the panel combined with the well Coupling support frame 20 having a self-elastic force is provided to correspond to the coupling error with the base 200.

본 발명의 패널 결합체(1)는 물의 빠른 유속이 직접 우물통기초(200)에 직접적인 영향을 미치지 않도록 보호하기 위함이다. The panel assembly 1 of the present invention is intended to protect the rapid flow rate of water does not directly affect the well well base 200.

한편, 상기 각 FRP코팅 철판패널(10)의 상단에는 크레인과 같은 별도의 인양수단(도시하지 않음)을 통해 인양케이블(도시하지 않음)과 연결하여 패널 결합체(1)를 인양하도록 인양고리(16)를 형성하되, 이와 같은 목적은 임의 설치시간의 경과 후 세굴현상의 진행과정을 관찰하기 위함이다. On the other hand, the upper end of each of the FRP-coated iron plate panel 10 is connected to the lifting cable (not shown) through a separate lifting means (not shown) such as a crane lifting ring 16 to lift the panel assembly (1). ), But this purpose is to observe the progress of scour phenomenon after a certain installation time.

상기와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다. Referring to the operation of the present invention configured as described above are as follows.

본 발명에 따른 패널 결합체(1)의 시공은 도 2 내지 도 3에 도시된 바와 같이 일단 우물통기초(200) 주변에 물막이 작업을 한 다음 그 우물통기초(200)의 주위로 감싸도록 본 발명의 단위 패널로써 FRP코팅 철판패널(10)과 FRP코팅 철판패널(10)의 각 결합레일(12)이 서로 마주하는 형태로 나란하게 위치시킨 다음 그 결합 레일(12)로 결합 지지틀(20)을 상부에서 하부로 끼워 결합하는 방법으로 연속하여 상기 FRP코팅 철판패널(10)을 설치하게 되면 상기 FRP코팅 철판패널(10)이 결합되는 패널 결합체(1)가 우물통기초(200)의 중심과 동심원이 되고, 상기 FRP코팅 철판패널(10)의 내면측에 설치된 슬라이더(14)가 그 사이 간격의 지지수단이 되어 유속에 대한 우물통기초(200)의 안정적인 보호수단이 되는 것이다. The construction of the panel assembly (1) according to the present invention, as shown in Figs. 2 to 3, once the water barrier work around the well well base 200, and then wrapped around the well well base (200) As a unit panel of the FRP coated griddle panel 10 and each of the coupling rails 12 of the FRP coated griddle panel 10 are placed side by side in a form facing each other and then the coupling support frame 20 by the coupling rail 12 When the FRP coated griddle panel 10 is installed continuously in a manner of fitting from the top to the bottom, the panel assembly 1 to which the FRP-coated griddle panel 10 is coupled is the center of the well base 200. Being concentric, the slider 14 installed on the inner surface side of the FRP-coated iron plate panel 10 serves as a support means of the gap therebetween to be a stable protection means of the well passage foundation 200 against the flow rate.

이와 같이 시공되는 본 발명은 우물통기초(200)의 표면으로 가해지는 물의 유속을 지속적으로 차단시켜 우물통기초(200) 표면의 침식현상, 즉 세굴현상을 방지하게 되는 것이다. The present invention constructed as described above is to prevent the erosion phenomenon, that is, scour phenomenon of the surface of the well well base 200 by continuously blocking the flow rate of water applied to the surface of the well well base 200.

이와 같음에도 불구하고 우물통기초(200)에 세굴현상의 관측하기 위해서는 상기 FRP코팅 철판패널(10)의 상부에 위치된 인양고리(16)에 크레인과 같은 별도의 인양수단(도시하지 않음)에 인양케이블(도시하지 않음)을 연결하여 리프팅시키면 슬라이더(14)에 의해 슬라이딩 이동되어 그 침식상태를 파악할 수 있다. Despite the same, in order to observe the scour phenomenon in the well base 200, a separate lifting means (not shown) such as a crane is attached to the lifting ring 16 located on the upper part of the FRP-coated iron plate panel 10. When the lifting cable (not shown) is connected and lifted, it can be slid and moved by the slider 14 to grasp the erosion state.

이상에서 설명한 본 발명은 전술한 실시예 및 첨부된 도면에 의해 한정되는 것은 아니고, 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 여러 가지 치환, 변경 및 변경이 가능하다는 것이 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에게 있어 명백할 것이다.The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, changes, and modifications are possible in the technical field of the present invention without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

이상에서와 같은 본 발명은 앞서 설명한 바와 같이 단위 패널을 다수 결합될 때 우물통기초의 중심과 동심원이 되는 형태로 에워 싸 물의 유속으로부터 원천적으로 차단하기 때문에 우물통기초의 표면이 침식되는 세굴현상을 방지하거나 그 진 행속도를 최대한 늦추는 효과가 탁월하기 때문에 교량의 수명이 종래에 비해 크게 연장되는 효과가 있다. As described above, the present invention blocks the scour phenomenon in which the surface of the well passage base is eroded because it is enclosed in a form concentric with the center of the well passage base when the unit panels are combined as described above. Since the effect of preventing or slowing the progress as far as possible is excellent, there is an effect of greatly extending the life of the bridge compared to the conventional.
