Description

유수에 의한 지반침식을 방지하는 교각안전구조{The Pier Safety Structure Of Ground Subsidence By Flowing Water}Pier Safety Structure Of Ground Subsidence By Flowing Water

본 발명은 교각의 하단의 기초가 되는 지반침식을 방지하고, 이를 통해 안정된 기반을 확보하여 교량의 안정된 구조를 유지할 수 있도록 된 유수에 의한 지반침식을 방지하는 교각안전구조에 관한 것이다.The present invention relates to a pier safety structure that prevents ground erosion that is the basis of the lower end of the bridge, and thereby prevents ground erosion by flowing water to secure a stable foundation to maintain a stable structure of the bridge.

일반적으로 도심지를 끼로 흐르는 하천이나 강에는 사람이 건널 수 있는 다리(교량)가 건설되는데, 대부분 차량통행이 가능하도록 되어 있어 비교적 큰 하중을 지탱하는 교각이 요구된다.In general, bridges (bridges) that can be crossed by people are built in rivers or rivers that flow through urban areas, and most of them are designed to allow vehicle traffic, requiring bridges that support relatively large loads.

그런데, 이러한 교각은 하천 애 토사층을 지지층으로 하여 입설되므로, 교각의 견고한 구성도 요구되지만, 기초가 되는 토사층의 안전성이 더욱 요구된다.By the way, since the piers are laid with the river soil soil layer as a supporting layer, a solid construction of the bridge is also required, but the safety of the foundation soil layer is further required.

한편, 하천의 유수는 하천바닥의 토사층에 침식 및 퇴적작용을 지속해서 가하므로, 교각을 지지하고 있는 토사층에도 지속적인 침식과 퇴적작용을 일으키게 되는데, 특히 교각은 하천의 소정 폭을 점유하여 일시적으로 유속을 증가시키므로 유수의 침식작용이 상대적으로 활발히 일어나게 되고, 결국 하천의 다른 위치보다 침하가 급격히 일어나게 되며, 지속적으로 침식된 틈에 의해 교각의 하중을 불균형적으로 지지하여 결국에는 교각을 붕괴시키는 원인이 되고 있는 바, 이러한 문제를 해소하기 위한 연구가 활발히 진행중이다.On the other hand, river runoff continuously exerts erosion and sedimentation on the sedimentary layers of the riverbed, causing continuous erosion and sedimentation on the sedimentary layers supporting the bridges. The erosion of the flowing water occurs relatively more actively, and the settlement occurs more rapidly than other locations in the river, and the erosion loads are disproportionately supported by the continuously eroded gaps, which eventually causes the pier to collapse. As a result, research is being actively conducted to solve these problems.

본 발명은 상기와 같은 문제를 해소하기 위하여 안출된 것으로서, 교각의 안전기반을 확보하면서 유수에 의한 지반침하를 최소화할 수 있도록 된 유수에 의한 지반침식을 방지하는 교각안전구조를 제공하려는데 그 목적이 있다.The present invention has been made to solve the above problems, to provide a bridge safety structure that prevents ground erosion caused by running water to minimize ground subsidence caused by running water while securing a safety base of the bridge. have.

위와 같은, 구성으로 이루어진 본 발명의 작동관계를 설명하면 다음과 같다.Referring to the operation of the present invention made of a configuration as described above are as follows.

우선, 본 발명에 따른 유수에 의한 지반침식을 방지하는 교각안전구조의 설치과정을 설명하면, 교각(1)의 둘레면에 토사유실방지부재본체(11)를 구성하는 밴드부(11a)와 버켓부(11b)를 배치한 상태에서 밴드부(11a)의 각 말단 면과 버켓부(11b)의 각 말단 면을 상호 연접하고, 연접된 둘레면을 용접을 통해 상호 고정한다.First, the installation process of the pier safety structure to prevent the ground erosion due to running water according to the present invention, the band portion 11a and the bucket portion constituting the soil loss prevention member body 11 on the circumferential surface of the pier (1) In the state where 11b is arrange | positioned, each end surface of the band part 11a and each end surface of the bucket part 11b are mutually connected, and the joined circumferential surface is mutually fixed by welding.

그리고, 상기 교각(1)의 상단에는 모터(21)와 권취드럼(22)으로 구성된 기중장치부(20)를 설치해주고, 교각(1)의 상단 양측에는 풀리를 각각 배치시켜 준 상태에서 와이어(W)를 이용하여 일단은 권취드럼(22)에 타단은 후크(h)를 매개로 견인부재(13)에 착탈가능하게 설치해주며, 상기 모터(21)의 작동을 ON/OFF 제어하는 스위치부(30)는 작업의 편의에 따라 교각(1)에 설치해주거나 또는 상판(2)에 설치해준다.In addition, the crane unit 20 including the motor 21 and the winding drum 22 is installed at the upper end of the pier 1, and the pulleys are disposed at both upper ends of the pier 1, respectively. Using W) one end of the winding drum 22, the other end is detachably installed to the traction member 13 via the hook (h), the switch unit for controlling the operation of the motor 21 ON / OFF ( 30 is installed on the piers (1) or on the top plate (2) according to the convenience of the work.

위와 같이, 설치한 상태에서 스위치부(30)를 눌러주게 되면, 전원이 인가되어 기중장치부(20)의 모터(21)로 전원이 공급되고, 공급된 전원에 의해 모터(21)가 구동됨과 동시에 모터(21)의 축핀에 연결된 권취드럼(22)이 함께 회전되면서 권취되어 있던 와이어(W)가 서서히 풀리게 되며, 따라서, 토사유실방지부재(10)를 서서히 하강시켜 교각(1)의 하부를 지지하고 있는 자갈과 토사의 상면으로 얹혀지도록 배치시켜 주면 된다.As described above, when the switch unit 30 is pressed in the installed state, power is applied to supply the power to the motor 21 of the crane unit 20, and the motor 21 is driven by the supplied power. At the same time, as the winding drum 22 connected to the shaft pin of the motor 21 is rotated together, the wound wire W is gradually released, and thus, the earth and sand loss preventing member 10 is gradually lowered to lower the pier 1. Place it on the top of the supporting gravel and soil.

한편, 교각(1)의 둘레면에 설치된 토사유실방지부재(10)의 주변으로 유수가 흐르게 되는데, 이때 교각(1)의 하부를 감싸고 있는 자갈과 토사가 유수에 의해 점 진적으로 침식되면서 유사와 함께 쓸려 내려가게 된다.On the other hand, the flow of water flows around the sediment loss prevention member 10 installed on the circumferential surface of the pier (1), the gravel and soil surrounding the lower portion of the pier (1) gradually eroded by the flow of water Swept down together.

이때, 유수로 인해 쓸려 내려가는 자갈과 토사는 버켓부(11b)의 수용부로 유입되고, 비교적 큰 자갈은 버켓부(11b)의 유수배출공(11b-1)에 걸려 수용부의 내부에 퇴적되게 되며, 퇴적되는 자갈로 인하여 유수만 유수배출공(11b-1)을 통해 배출되고, 토사는 자갈로 인해 퇴로가 막혀 더 이상 배출되지 않고 내부에 쌓이게 된다.At this time, the gravel and earth and sand are washed down due to running water flows into the receiving portion of the bucket portion (11b), the relatively large gravel is seized in the inside of the receiving portion caught by the drainage hole (11b-1) of the bucket portion (11b), Due to the gravel being deposited, only the discharged water is discharged through the discharged water discharge hole 11b-1, and the earth and sand are piled up inside without being discharged anymore due to clogging.

따라서, 수용부에 자갈과 토사가 어느 정도 유입되어 쌓이게 되면, 더 이상 자갈과 토사가 유입되지 못하게 되면서, 유수의 흐름 방향에 반대 방향으로 자갈과 토사가 점진적으로 퇴적되고, 점진적으로 퇴적되는 자갈과 토사로 인하여 유수에 의해 유실된 부분이 서서히 매꿔져 침식으로 인한 교각(1)의 기울어짐, 더 나아가서는 교각(1)의 붕괴를 방지할 수 있게 되는 것이며, 이러한 일련의 과정을 도 3 내지 도 4와 같이 도시하였다.Therefore, when some amount of gravel and soil is accumulated and accumulated in the receiving part, the gravel and soil are no longer introduced, and the gravel and soil are gradually deposited in the opposite direction to the flow of the flowing water, The part lost by the runoff due to the soil is gradually filled to prevent the inclination of the pier (1) due to erosion, and further to prevent the collapse of the pier (1). 4 is shown.

이와 같이, 상기 교각(1)의 둘레면에 토사유실방지부재(10)를 설치하여 줌으로서, 유수에 의해 교각(1)을 지탱하고 있는 모래 및 자갈 등의 토사(2) 유출시 교각(1)의 주변을 따라 이동되는 유수와 함께 쓸려 내려가는 토사(2)를 내부에 수용할 수 있도록 하여 침식으로 인한 지반의 침하를 최소화하고, 토사(2)의 유실을 방지할 수 있게 되는 것이다.In this way, by installing the earth and sand loss prevention member 10 on the circumferential surface of the pier (1), the pier (1) when the soil (2) such as sand and gravel holding the pier (1) by the running water outflows By allowing the sediment (2) to be swept down with the flowing water moving along the periphery, it is possible to minimize the settlement of the ground due to erosion, and to prevent the loss of the soil (2).

또한, 상기와 같이 교각(1)의 상부에 기중장치부(20)와 풀리 및 스위치부(30), 와이어(W)를 설치하여 줌으로서, 토사유실방지부재(10)를 안전하게 승하강 시켜 줄 수 있어 작업의 편의성을 향상된다.In addition, by installing the lifting unit 20, the pulley and the switch unit 30, the wire (W) in the upper portion of the pier (1) as described above, the earth and sand loss prevention member 10 will be raised and lowered safely It can improve the convenience of work.
