Description
본 발명은 해상 교량의 거더 브리지 설치 시공방법에 관한 것으로, 더욱 상세하게는 해상 교량의 교각 간에 거더 브리지(행교 또는 강교)를 설치함에 있어 시공수와 시공기간을 현저히 단축할 수 있을 뿐만 아니라 안전한 시공이 가능하여 시공성과 경제성 및 작업 안전성을 향상시킬 수 있는 해상 교량의 거더 브리지 설치 시공방법에 관한 것이다.The present invention relates to a method for installing a girder bridge of an offshore bridge, and more particularly, in installing a girder bridge (hanging bridge or steel bridge) between piers of an offshore bridge, it is possible to significantly shorten the number of construction and construction period as well as safe construction. The present invention relates to a method of installing a girder bridge for offshore bridges that can improve workability, economy, and work safety.
일반적으로, 교량은 상부구조와 교각과 교대로 이루어지는 하부구조로 이루어지는데, 상기 상부구조는 콘크리트구조물이나 철골구조물로 이루어진다.In general, a bridge consists of an upper structure and a lower structure made of alternating piers, and the upper structure is made of a concrete structure or a steel structure.
상기 철골구조물로 이루어지는 교량의 경우 플레이트 블럭과 상기 플레이트 블럭을 지지하기 위해서는 크로스 거더(cross girder)로 이루어진다.In the case of a bridge made of the steel structure, a plate block and a cross girder are used to support the plate block.
특히 현수교 및 사장교의 경우 크로스 거더(이하 '거더'라 한다)는 주케이블에 매달려 아래로 드리워지는 행어(hanger) 케이블에 의해 양단이 결합되고 그 위에 서로 맞대어 결합되는 플레이트 블럭들이 얹혀 순차적으로 연결되어 교량 상판을 이루게 된다.In particular, in the case of suspension bridges and cable-stayed bridges, cross girders (hereinafter referred to as ``girders'') are connected at both ends by a hanger cable hanging down from the main cable, and plate blocks that are joined to each other are placed on top of the cross girder. It forms the top of the bridge.
또한, 종래의 현수교 및 사장교의 설치를 위해서는 바지선으로 플레이트 블럭들을 실어와서 거대한 기중기(타워 크레인)로 이를 들어올려 거더에 올려놓고 결합하는 방식을 사용하고 있다.In addition, for the installation of conventional suspension bridges and cable-stayed bridges, plate blocks are loaded with a barge, lifted with a huge crane (tower crane), and mounted on a girder and combined.
그러나 종래 교량 시공 방법에 있어서 교각(pier)과 교각 사이에 거더 브리지(girder bridge: 행교)를 설치할 때, 바지선에 거더 브리지를 싣고 이를 교각 사이에 리프팅하여 설치하기 위해서는 바지선에서 거더를 잭업(Jack Up)하여 올려 설치하거나 바지선에 리프팅 타워를 설치하여 리프팅하여 거더를 설치해야만 한다. 이때 리프팅 타워의 높이가 타워 크레인의 높이가 교각의 높이보다 높아야 하고, 이에 따라 거더 브리지의 설치 후 바지선이 빠져나오기 위해서는 타워 크레인을 교각 높이보다 낮게 제거하거나 분리해야 하며, 이는 결국 공정수와 공사 기간이 증가하고, 이에 따라 교량 작업의 비용을 크게 상승시키는 문제점이 있었다.However, in the conventional bridge construction method, when installing a girder bridge between the pier and the pier, jack up the girder from the barge to install the girder bridge by loading it on the barge and lifting it between the piers. ), or by installing a lifting tower on a barge and lifting to install a girder. At this time, the height of the lifting tower must be higher than the height of the tower crane, and accordingly, in order for the barge to escape after the installation of the girder bridge, the tower crane must be removed or removed lower than the height of the pier. This increases, and thus there is a problem of significantly increasing the cost of the bridge work.
또한, 이러한 해상에서의 리프트 타워의 해제 작업 또는 제거 작업은 해상이라는 특성상 안전사고 발생을 초래할 가능성이 현저히 증가하는 문제점이 있으며, 이에 따라 해상에서의 교량 시공 방법에 대한 보다 효율적인 시공 방법에 대한 연구가 절실한 상황이다.In addition, the lifting or removal of the lift tower at sea has a problem that the possibility of causing a safety accident is significantly increased due to the nature of the sea, and accordingly, research on a more efficient construction method for a bridge construction method at sea It is a desperate situation.
따라서, 상기한 종래의 문제점을 해결하기 위한 본 발명은, 해상 교량의 교각 간에 거더 브리지(행교 또는 강교)를 설치함에 있어 시공수와 시공기간을 현저히 감소시킬 수 있을 뿐만 아니라 안전한 시공이 가능하여 시공성과 경제성 및 작업 안전성을 향상시킬 수 있는 해상 교량의 거더 브리지 설치 시공방법을 제공하는데 그 목적이 있다.Therefore, the present invention for solving the above-described conventional problems, when installing a girder bridge (hanging bridge or steel bridge) between piers of an offshore bridge, it is possible to significantly reduce the number of construction and construction period, as well as safe construction.

상기 바지선(B)에는 상단에 리프팅 설비로서 스트랜드잭이 설치된 스트랜드잭 리프트타워(L)가 소정 간격을 갖고 복수 설비되어 있으며, 여기에서 상기 스트랜드잭 리프트타워(L)는 거더브리지(110)가 설치될 교각의 높이보다 낮은 높이를 갖는 스트랜드잭 리프트타워로 설비된다. 이는 후술하는 설치 완료 단계에서 거더브리지(110)가 교각에 설치된 후 바지선의 진입방향과 반대방향으로 용이하게 빠져나올 수 있게 된다.The barge (B) is equipped with a plurality of strand jack lift towers (L) with a strand jack installed at the top as a lifting facility at predetermined intervals, wherein the strand jack lift tower (L) is equipped with a girder bridge (110). It is equipped with a strand jack lift tower with a height lower than the height of the pier to be used. This allows the

이러한 거더브리지 로딩 단계(S300)의 트랜스포터(S) 이동 과정에서, 트랜스포터(S)가 진입됨에 따라 바지선(B)의 평형수를 조절하여 육상 부두의 상면과 바지선(B)의 상면이 거의 동일 평면 상에 있도록 하게 된다.In the process of moving the transporter (S) in the girder bridge loading step (S300), as the transporter (S) enters, the ballast water of the barge (B) is adjusted so that the upper surface of the land pier and the upper surface of the barge (B) are almost They are on the same plane.

Then, the transporter (S) is moved to the land by the barge (B) while the first structure is separated from the upper surface of the barge (B) by the mobile support (M). The movable support (M) is fixed at a position having a space through which the transporter (S) can pass.
이후, 바지선(B)을 부두에 고박, 바람직하게는 도 6에 나타낸 바와 같이 거더브리지(110)가 부두에 평행하도록 바지선(B)을 접안하여 고박한 다음, 도 7의 우측 그림에 나타낸 바와 같이 스트랜드잭 리프트 타워(L)의 스트랜드잭을 로딩빔(110)에 연결하여 제1 구조물을 바지선(B)으로부터 소정 높이 리프팅한다.Thereafter, the barge (B) is anchored to the pier, preferably, as shown in FIG. 6, the barge (B) is docked and anchored so that the girder bridge (110) is parallel to the pier, as shown in the right figure of FIG. The strand jack of the strand jack lift tower (L) is connected to the loading beam (110) to lift the first structure from the barge (B) to a predetermined height.
다음으로, 트러스구조물 로딩 단계(S500)는, 도 8 및 도 9의 좌측 그림에 나타낸 바와 같이, 제작된 높이보상 트러스구조물(120)을 실은 트랜스포터(S)를 이용하여, 부두에 접안된 바지선(B)(교각 높이보다 낮은 높이를 갖는 스트랜드잭 리프트타워(L)가 설비된 바지선)으로 이동시켜서, 소정 높이 리프팅되어 있는 제1 구조물의 하부(즉, 로딩빔(110)의 하부) 측에 이동 완료 후, 도 9의 우측 그림에 나타낸 바와 같이, 트랜스포터(S)의 자체 승강장치를 통해 하강하여 높이보상 트러스구조물(120)을 이동식 지지대(M)의 상면에 안착시킨다.Next, the truss structure loading step (S500), as shown in the left figure of Figs. 8 and 9, using a transporter (S) loaded with the manufactured height
여기에서, 높이보상 트러스구조물(120)은 교각 높이보다 낮은 높이를 갖는 스트랜드잭 리프트타워(L)의 최대 상승 높이를 고려하여 설계 제작된 높이를 갖는 구조물이다.Here, the height
다음으로, 상기 로딩빔 컷팅 단계(S600)는, 스트랜드잭 리프트타워(L)를 이용하여 제1 구조물을 하강시켜, 이동식 지지대(M)의 상면에 안착된 트러스구조물(120) 상면에 안착시킨 다음, 리프팅용 로딩암(110)의 양 가장자리를 소정 길이 컷팅하여 높이보상 트러스 구조물(120)의 리프팅을 위한 통로를 확보하며, 확보된 통로를 통해 스트랜드잭 리프트타워(L)의 스트랜드 와이어를 트러스구조물(120)의 양단부에 결합시킨다(도 11 참조). 이하, 제1 구조물에 트러스구조물이 결합된 구조물을 제2 구조물이라 칭한다.Next, in the loading beam cutting step (S600), the first structure is lowered using the strand jack lift tower (L), and the
다음으로, 상기 거더브리지 설치 준비 단계(S700)는, 상기 로딩빔 컷팅 단계(S600) 완료 후, 거더브리지(200)를 설치할 교각(P) 측방으로 바지선(B)을 이동하고, 바지선(B)의 평형수를 조절하여 바지선(B)의 높이를 소정 높이로 밸런싱하게 된다. 이러한 거더브리지 설치 준비 단계(S700)는 생략되거나, 트러스구조물 리프팅 단계(S800)와 동시에 실행될 수 있다.Next, in the girder bridge installation preparation step (S700), after the loading beam cutting step (S600) is completed, the barge (B) is moved toward the side of the pier (P) where the
다음으로, 상기 트러스구조물 리프팅 단계(S800)는, 도 14에 나타낸 바와 같이 바지선(B)을 거더브리지 설치를 위한 위치로 안정적으로 이동시키기 위하여 바지선(B)의 양측에 복수의 윈치를 연결하여 고박한 다음, 바지선(B)의 스트랜드잭 리프트타워(L)를 이용하여 제2 구조물을 리프팅하되, 제2 구조물의 거더브리지(200)가 교각(P)의 높이보다 소정 높이 높은 위치까지 상승시킨다. 바람직하게는, 거더브리지(200)가 교각(P)의 상단보다 약 2.5M 정도 높은 위치에 있도록 제2 구조물을 상승시킨다.Next, the truss structure lifting step (S800) is secured by connecting a plurality of winches to both sides of the barge (B) in order to stably move the barge (B) to a position for installing the girder bridge, as shown in FIG. Then, the second structure is lifted using the strand jack lift tower (L) of the barge (B), but the
여기에서, 스트랜드잭 리프트타워(L)의 높이는 교각(P)의 높이보다 낮으나, 높이보상 트러스구조물(120) 및 로딩빔(110)의 높이에 의해 거더브리지(200)가 교각(P)의 높이보다 높게 위치되는 것이다.Here, the height of the strand jack lift tower (L) is lower than the height of the pier (P), but by the height of the height compensation truss structure (120) and the loading beam (110), the girder bridge (200) is the height of the pier (P) It is positioned higher.
다음으로, 상기 설치위치 이동 단계(S900)는, 도 16 및 도 17에 나타낸 바와 같이, 바지선(B)의 양측에 연결되어 고박된 윈치를 이용하여 일측의 윈치와 타측의 윈치를 서로 연동시켜 천천히 감고 풀면서 거더브리지(200)가 교각(P)의 설치 위치까지 바지선(B)을 이동시키게 된다.Next, the installation position moving step (S900), as shown in Figs. 16 and 17, by using a winch connected to both sides of the barge (B) and fixed by interlocking the winch of one side and the winch of the other side slowly While winding and unwinding, the
다음으로, 상기 설치 완료 단계(S1000)는, 도 18에 나타낸 바와 같이 제2 구조물을 하강시켜 교각(P) 사이에 거더브리지(200)의 양단부를 두 교각의 설치부에 설치시키고, 거더브리지(200)와 로딩빔(110)을 분리한 후, 도 19 및 도 20에 나타낸 바와 같이 로딩빔(110)과 높이보상 트러스구조물(120)을 소정 높이 하강시킨 다음, 즉 로딩빔(110)과 높이보상 트러스구조물(120)을 스트랜드잭 리프트타워(L)의 높이보다 낮게 하강시킨 상태 또는 이동식 지지대(M)에 안착시킨 상태에서 바지선을 설치 위치로부터 이동시켜서 거더브리지(200)의 설치 시공을 완료하도록 이루어진다.Next, in the installation completion step (S1000), as shown in FIG. 18, the second structure is lowered to install both ends of the
상기 설치 완료 후 바지선의 이동은 바지선(B)의 양측에 연결되어 고박된 윈치를 이용하여 일측의 윈치와 타측의 윈치를 서로 연동시켜 천천히 감고 풀면서 실행할 수 있으며, 설치 후 고박을 풀고 바지선(B) 자체를 이동시켜서 실행할 수 있다.After the installation is completed, the movement of the barge can be carried out by slowly winding and unwinding by interlocking the winch on one side and the winch on the other side by using a winch connected to both sides of the barge (B). ) It can be executed by moving itself.
예를 들면, 바지선(B)에 설비된 스트랜드잭 리프트타워(L)가 교각의 높이보다 높을 경우, 거더브리지(200)의 설치 후 그 거더브리지(200)로 인하여 교각으로부터 벗어날 수 없었으나, 상기와 같이 본 발명은 스트랜드잭 리프트타워(L)의 높이가 교각보다 낮더라도 높이보상 트러스구조물을 통해 설치 높이를 보상하고, 거더브리지의 설치 후 거더브리지에 의해 방해받는 일 없이 거더브리지의 설치 위치로부터 쉽게 벗어날 수 있게 된다.For example, if the strand jack lift tower (L) installed in the barge (B) is higher than the height of the pier, after the
물론, 스트랜드잭 리프트타워(L)의 높이를 교각보다 낮추기 위하여 상단부를 제거하거나 분리할 수 있으나, 이는 종래 기술의 문제점에서 언급한 바와 같이 공정수와 공사 기간이 증가하여 교량 작업의 비용을 크게 상승시킬 뿐만 아니라, 해상의 특성상 제거 또는 분해 과정에서 안전사고가 발생되는 문제점이 있었으며, 본 발명은 교각보다 낮은(다시 말해서, 설치된 거더브리지의 높이보다 낮은 스트랜드잭 리프트타워(L)를 이용하더라도 상기한 과정을 거쳐 이러한 문제점을 해결한 것이다.Of course, the upper part of the strand jack lift tower (L) can be removed or separated in order to lower the height of the pier, but this increases the number of processes and construction period as mentioned in the problem of the prior art, greatly increasing the cost of the bridge work. In addition, there was a problem that safety accidents occurred in the removal or disassembly process due to the nature of the sea, and the present invention has a problem with the above-described use of a strand jack lift tower (L) lower than the pier (that is, the height of the installed girder bridge). This problem was solved through the process.
