The present invention relates to an installation to prevent the scour of the piers caused by the flow velocity.
본 고안은 교각 기초부분의 세굴방지구조에 관한 것으로서, 더욱 상세하게는 교량을 지지하는 교각을 설치할 때, 그 교각 우물통 기초 하부의 외측 둘레면에 세굴방지대를 설치함으로써 우물통 기초 하부의 세굴현상을 방지할 수 있도록 하기 위한 교각 기초부분의 세굴방지구조에 관한 것이다.The present invention relates to the scour prevention structure of the foundation part of the bridge, more specifically, when installing the bridge supporting the bridge, the scour at the bottom of the well basin base by installing a scour prevention bar on the outer peripheral surface of the bottom of the bridge well basin base It relates to a scour prevention structure of the foundation part of the piers to prevent the phenomenon.
일반적으로 강을 횡단하는 교량을 설치할 때에는 강의 바닥부분에 우물통 기초(200)를 침설하여 고정시키고 그 중앙부에 피어부(100)를 축조하여 구축된다.In general, when installing the bridge across the river is settled by fixing the well base 200 in the bottom portion of the river and is constructed by constructing the pier part 100 in the center thereof.
이와 같이 구축되어진 상기 우물통 기초(200)의 하부는 도1에 도시된 바와 같이, 시간이 경과됨에 따라 흐르는 강물의 속도 또는 상류에서 하류측으로 이동되는 수중물체에 의해서 부딪혀서 변형(세굴현상)이 발생하게 된다.As shown in FIG. 1, the lower part of the well basin base 200 constructed as described above is hit by a velocity of the flowing river or an underwater object moving upstream from the upstream side as time elapses so that deformation (washing phenomenon) occurs. Done.
그러나 변형이 심할 경우에는 피어부(100)를 손상시키게 되고 상기 피어부(100)가 손상되면 교량이 붕괴되는 등의 문제점을 일으키게 된다.However, if the deformation is severe, the peer portion 100 is damaged, and if the peer portion 100 is damaged, problems such as collapse of the bridge are caused.
이러한 문제점을 해결하기 위하여 종래에는 포대콘크리트를 수중에 투하하는 공법을 이용하고 있으나, 이러한 공법은 크레인을 이용하거나 굴삭기 장비를 이용하여 투하하게 되므로 수중고르기가 일정하지 못하여 부실 시공사례가 발생하였고, 세굴방지용 콘크리트 포대가 터지는 등 재 시공비에 막대한 비용이 소요되는 등의 문제점이 있었다.Conventionally, in order to solve this problem, the method of dropping the bag concrete in the water is used, but such a method is dropped by using a crane or an excavator equipment. There was a problem such as a huge cost for the reconstruction cost, such as the explosion of the concrete sacks to prevent.
본 발명은 상기한 종래 문제점을 개선하기 위해 제안된 것으로서, 저렴한 시공비로 효율적으로 교량의 피어부의 세굴을 방지할 수 있도록 하는 것이 목적이다.The present invention has been proposed to improve the above-mentioned conventional problems, and an object of the present invention is to be able to effectively prevent scouring of a pier part of a bridge at a low construction cost.
상기 기술한 목적을 달성하기 위하여, 교량의 피어부 하단에 설치되는 우물통 기초의 세굴을 방지하기 위한 우물통 기초의 세굴방지대에 있어서, 하부에 회전바퀴가 설치되며 외측부는 평면이나 내측부는 유선형으로 형성된 세굴방지블록과; 내부는 중공부가 형성되며 외주면으로 나사형상의 세굴방지블럭 설치홈이 상부를 시작으로 하부까지 형성되는 한편, 상기 세굴방지블럭 설치홈에는 세굴방지블록이 구를 수 있는 레일부가 형성되며, 상기 레일부에 연장되게 형성되며 세굴방지블록의 이탈을 방지하는 가이드부가 구비된 나사선식 회전고정틀를 포함하여서 구성되는 것을 특징으로 하는 우물통 기초의 세굴방지대를 제공한다.In order to achieve the above object, in the well base of the well to prevent the scour of the well base installed in the lower end of the bridge portion of the bridge, the rotating wheel is installed in the lower portion and the outer portion is flat or the inner portion is streamlined Scour prevention block formed with; A hollow part is formed inside, and a screw-shaped scour prevention block installation groove is formed from the upper side to a lower portion, while the scour prevention block installation groove is formed with a rail portion through which the scour prevention block can be rolled. It is formed to extend to the scour prevention block provides a scrub prevention base of the well bucket, characterized in that it comprises a screw-type rotary fixing frame provided with a guide to prevent the separation.
