본 발명은 수중구조물의 안전진단장치에 관한 것으로서, 보다 상세하게는 교량의 종류, 규모, 수리 및 수문 특성, 주변 지형 상태나 기후 상태에 상관없이, 간편하고 안전하게 교량의 세굴 심도를 측정할 수 있는 수중구조물의 안전진단장치에 관한 것이다.The present invention relates to a safety diagnosis device for an underwater structure, and more particularly, it is possible to measure the scour depth of a bridge easily and safely regardless of the type of bridge, size, repair and hydrological characteristics, surrounding topography or climatic conditions. The present invention relates to a safety diagnosis device for an underwater structure.

일반적으로 강이나 하천을 횡단하는 교량을 설치할 때에는 강의 바닥부분에 우물통을 이용하여 교각기초를 침설 고정하고, 그 교각기초 중앙부에 교각을 지지하도록 된 피어부인 교각기둥을 구축하게 된다.Generally, when installing bridges that cross rivers or rivers, the foundation of the bridge is settled and fixed by using a well at the bottom of the river, and the piers, which are peer parts, are constructed to support the bridge at the center of the bridge foundation.

이와 같이 구축되는 교각기초(60)의 하부측은 시간이 경과함에 따라 도 3과 같이, 흐르는 강물의 속도 또는 상류에서 하류로 이동되는 수중물체에 부딪혀서 변형(세굴현상)이 발생되기도 한다. 이때, 변형이 심할 경우에는 그 중심부에 위치한 피어부까지 손상시키게 되면서 교량이 붕괴되는 위험을 초래하기도 한다.As shown in FIG. 3, the lower side of the bridge foundation 60 constructed as described above may be deformed (washing phenomenon) by hitting an underwater object moving downstream from the speed or upstream of the flowing river. At this time, if the deformation is severe, even damage to the peer portion located in the center may cause the bridge collapse.

이렇게 교량 하부 지반의 세굴로 인한 교량의 피해를 줄이기 위해서는, 교량 하부 구조에 대한 지속적인 유지 관리가 필요하며, 이를 통해서 세굴의 진행 상태와 교량의 건전도를 정확히 조사하고 평가해야 한다.In order to reduce the damage of bridges caused by scour of the subsurface of bridges, continuous maintenance of bridge substructures is required. Through this, the progress of scouring and the health of bridges must be accurately investigated and evaluated.

이를 위한 종래의 교대나 교량의 세굴 상태의 조사는, 작업원이 교량 하부로 내려가 수심 측정 막대기(sounding pole)로 직접 세굴 상태를 측정하거나, 보트를 타고 세굴 심도를 조사하는 등의 기초적인 방법으로 수행되어 왔었다.Conventional scrubbing of bridges or bridges is based on basic methods, such as when a worker descends under a bridge and directly measures the scour depth with a sounding pole or examines the scour depth by boat. It has been done.

그러나, 이와 같은 방법은 기상 상태나 지형 조건에 따라서 작업이 어렵고, 작업속도가 느리며, 또한 정확한 세굴심을 측정하기가 곤란할 뿐만 아니라, 작업의 안전성도 결여되는 문제점이 있었다.However, such a method is difficult to work depending on weather conditions or terrain conditions, the work speed is slow, and it is difficult to measure accurate scour depth, and also there is a problem that the safety of the work is also lacking.

또한, 기존 교량 세굴 조사 방법 중, 수면 아래의 세굴 상태를 조사하는 방법에는 잠수부를 이용하는 방법이 있는바, 이러한 방법은 상당히 정밀한 세굴 상태나 교각의 파손 상태를 조사할 수 있으나, 유속이 빠를 경우 조사가 어려우며, 작업시 잠수부의 안전에 위험을 초래할 수 있고, 세굴 상태를 조사하기 위한 작업 시간이 길며, 조사 비용이 상대적으로 많이 소요되는 문제점이 있었다.In addition, among the existing bridge scrubbing methods, there is a method of investigating the scour conditions under the water, which can be used to investigate the precise scour conditions or breakage state of the piers, but if the flow rate is fast It is difficult, may cause a risk to the safety of the diver during the operation, the work time for investigating the scour state is long, there was a problem that the irradiation cost is relatively high.

따라서, 앞서 언급한 바와 같은 종래의 세굴 조사 방법의 문제점을 개선할 수 있는 새로운 교량 세굴 조사 장치의 개발이 절실히 요청되고 있다.Therefore, there is an urgent need for the development of a new bridge scrubbing apparatus that can improve the problems of the conventional scour irradiation method as described above.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 교량의 종류, 규모, 수리 및 수문 특성, 주변 지형 상태나 기후 상태에 상관없이, 간편하고 안전하게 교량의 세굴 심도를 측정할 수 있는 수중구조물의 안전진단장치를 제공함에 그 목적이 있다.The present invention is to solve the above problems, safety of the underwater structure that can easily and securely measure the scour depth of the bridge, regardless of the type, size, repair and hydrological characteristics of the bridge, the topography or weather conditions The purpose is to provide a diagnostic device.

The ball spring 30 is to close the fastening band 50 to the outer periphery of the bridge foundation 60, is installed on the opposite side of the flow rate sensor 40 on the basis of the bridge foundation 60, the bridge foundation (60) Located between the circumferential surface and the inner circumference of the fastening band 50 is to move the fastening band 50 to the outside as much as the scoured depth of the pier foundation 60.

상기 래크(20)는 탄발스프링(30)에 의해 외부로 이동되는 체결밴드(50)에 의해 외부로 동반이동되는 평기어로, 상기 탄발스프링(30)에 의해 외부로 탄발되는 체결밴드(50) 외주연 선단에 고정되어 교각기초(60)에 축고정되어 회동되는 피니언(21)에 기어결합되어 수평이동된다. The rack 20 is a spur gear that is externally moved by the fastening band 50 which is moved to the outside by the carbon spring 30, and the fastening band 50 which is carbonized to the outside by the carbon spring 30. It is fixed to the outer periphery of the gear is fixed to the pier foundation 60, the gear is coupled to the pinion 21 is rotated and is moved horizontally.

상기 측정대(10)는 피니언(21)에 기어결합되어 세굴변위를 외부로 나타내는 것으로, 상기 래크(20)와 기어결합된 피니언(21)의 타측에 기어결합되는 기어부(11)가 형성되고, 고정대(22)에 지지간(12)에 의해 승강가능하게 지지되어 교각기초(60) 상단에 고정된 측정핀(13)과 인접되어 승강변위를 외부로 표출한다.

이와 같은 본 발명의 사용상태를 설명하면 다음과 같다.Referring to the use state of the present invention as follows.

먼저, 도 1과 같이, 교각기초(60)의 하부에 세굴이 발생되지 않을 때에는 유속감지기(40)에 의해서 감지된 유속이 유속변화측정기(42)에 의해 표출되어 측정되고, 그 상태에서 측정대(10)의 상단이 측정핀(13)에 의해 지시된 부위가 측정되어 표시된다.First, as shown in FIG. 1, when scour is not generated in the lower part of the bridge foundation 60, the flow rate detected by the flow rate sensor 40 is expressed and measured by the flow rate change measuring unit 42. The upper end of 10 is measured and displayed by the measuring pin 13.

이 상태에서 도 2와 같이, 교각기초(60) 하부에 세굴이 발생되면, 체결밴드(50)는 탄발스프링(30)의 탄발력에 의해서 세굴심도만큼 외측방향으로 이동되면서 교각기초(60)의 외주연과 밀착되고, 이때 외부로 이동된 체결밴드(50)의 이동거리만큼 래크(20)는 기어결합된 피니언(21)을 회동시키며, 피니언(21)을 다시 기어 결합된 기어부(11)에서 측정대(10)를 상측으로 상승시키게 된다.In this state, as shown in FIG. 2, when scour is generated under the pier foundation 60, the fastening band 50 is moved outward as much as the scour depth by the repulsive force of the ball spring 30. In close contact with the outer circumference, the rack 20 rotates the geared pinion 21 by the movement distance of the fastening band 50 moved to the outside, and the gear unit 11 geared back to the pinion 21.
