Description

지반침하를 보완하는 교각안전지지대{The Pier Safety Supporter Of Ground Subsidence}Pier Safety Supporter Of Ground Subsidence

본 발명은 교각을 지탱하는 지반의 침하를 최소화하여 교량의 안전기반을 확보하는 한편, 지반침하 정도에 따른 높낮이 조정을 통해 교각의 구조와 위치에 상관없이 적용 가능한 지반침하를 보완하는 교각안전지지대에 관한 것이다.The present invention is to secure the foundation of the bridge by minimizing the settlement of the ground supporting the bridge, while the height of the bridge according to the degree of ground subsidence to complement the ground settlement applicable irrespective of the structure and position of the bridge to the bridge safety support It is about.

일반적으로 도심지를 끼고 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 along urban centers, and most of them require traffic to be carried by 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 지반침하를 보완하는 교각안전지지대를 제공하려는데 그 목적이 있다.The present invention has been made in order to solve the above problems, it is an object of the present invention to provide a bridge safety support to complement the ground settlement that can minimize the ground settlement caused by running water while securing a safety base of the bridge.

It is possible to accommodate the descending gravel and soil inside to minimize settlement of the ground due to erosion, and to prevent the loss of gravel and soil.

위와 같은 구성으로 이루어진 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention made of the above configuration as follows.

우선, 본 발명에 따른 지반침하를 보완하는 교각안전지지대의 설치과정을 설명하면, 도 2와 같이 설치된 교각(1)의 둘레면에 토사유실방지부재(10)를 구성하는 밴드부(11)와 버켓부(12)를 배치한 상태에서 밴드부(11)의 각 말단 면과 버켓 부(12)의 각 말단 면을 상호 연접하고, 연접된 둘레면을 용접을 통해 상호 고정한다.First, when explaining the installation process of the pier safety support to complement the ground settlement according to the present invention, the band section 11 and the bucket constituting the soil loss prevention member 10 on the circumferential surface of the pier (1) installed as shown in FIG. In the state which arrange | positioned the part 12, each end surface of the band part 11 and each end surface of the bucket part 12 are mutually connected, and the joined circumferential surface is mutually fixed by welding.

상기와 같이 고정시켜 준 상태에서 바지선에 설치된 크레인의 후크를 이용하여 토사유실방지부재(10)를 서서히 하강시켜 교각(1)의 하부를 지지하고 있는 자갈과 토사의 상면으로 얹혀지도록 배치시켜 주면 된다.In the fixed state as described above, by using the hook of the crane installed on the barge, the earth and sand loss prevention member 10 is gradually lowered to be placed on the upper surface of the gravel and the soil supporting the lower part of the piers (1). .

한편, 교각(1)의 둘레면에 설치된 토사유실방지부재(10)의 주변으로 유수가 흐르게 되는데, 이때 교각(1)의 하부를 감싸고 있는 자갈과 토사가 유수에 의해 점진적으로 침식되면서 유수와 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) is gradually eroded by the flow of water along with the running water It is washed away.

이때, 유수로 인해 쓸려 내려가는 자갈과 토사는 버켓부(12)의 수용부로 유입되고, 비교적 큰 자갈은 버켓부(12)의 유수배출공(12a)에 걸려 수용부의 내부에 퇴적되게 되며, 퇴적되는 자갈로 인하여 유수만 유수배출공(12a)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 the flowing water flows into the receiving portion of the bucket portion 12, the relatively large gravel is seized in the inside of the receiving portion caught by the drainage hole (12a) of the bucket portion 12, Due to the gravel, only the running water is discharged through the running water discharge hole 12a, and the soil is accumulated in the inside without being discharged anymore due to clogging due to the gravel.

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 줌으 로서, 유수에 의해 교각(1)을 지탱하고 있는 자갈과 토사의 유출시 교각(1)의 주변을 따라 이동되는 유수와 함께 쓸려 내려가는 자갈과 토사를 내부에 수용할 수 있도록 하여 침식으로 인한 지반의 침하를 최소화하고, 자갈과 토사의 유실을 방지할 수 있게 되는 것이다.Thus, by installing the earth and sand loss prevention member 10 on the circumferential surface of the pier (1), along the periphery of the pier (1) when outflow of gravel and earth and sand holding the pier (1) by running water It will be able to accommodate the gravel and soil that is swept away with the flowing water to minimize the settlement of the ground due to erosion, and to prevent the loss of gravel and soil.
