Description

물막이 부재를 설치한 기초 구조체의 세굴방지 및 기초 보강방법 { Scouring protection and reinforcement method installing coffer dam footing body }Scouring protection and reinforcement method installing coffer dam footing body}

본 발명은 기초 구조체의 보강방법에 관한 것으로서, 더욱 상세하게는 교량이나 옹벽을 지지하는 기초구조체가 흐르는 물에 의해 세굴됨에 따라 지지력이 감소된 것을 보강하되 기초구조체가 설치된 바닥면에 물막이 부재를 설치하여 새로이 보강된 후에 추가 세굴이 발생하는 것을 방지하고 기초구조체의 지지력을 증대시킬 수 있는 기초구조체의 보강방법에 관한 것이다.
The present invention relates to a method for reinforcing a foundation structure, and more particularly, to reinforce that the bearing capacity is reduced as the foundation structure supporting the bridge or retaining wall is scoured by flowing water, but a water barrier member is installed on the bottom surface on which the foundation structure is installed. The present invention relates to a method of reinforcing a foundation structure, which can prevent additional scouring from occurring after the new reinforcement and increase the bearing capacity of the foundation structure.

일반적으로 교량이나 옹벽 등의 구조체는 강이나 하천을 건너기 위해 강이나 하천 바닥에 세워진 교각이나 교대와 같은 기초구조체에 의해 지지되도록 이루어진다.In general, a structure such as a bridge or a retaining wall is made to be supported by a foundation structure such as a bridge or a shift bridge built on a river or a river bottom to cross a river or a river.

이러한 기초구조체는 도 7에 도시된 바와 같이, 강이나 하천 바닥에 세워지기 때문에 흐르는 강물이나 하천에 의한 유수작용에 의해서 한계소류력 이상이 되면 기초구조체의 가장자리가 점차 쓸려 패이는 세굴현상이 발생한다.As shown in FIG. 7, since the foundation structure is built on the river or river bottom, the edge of the foundation structure is gradually swept away when the limiting force is exceeded due to the flow of the river or the river.

이러한 세굴현상이 일어난 기초구조체의 가장자리가 패이는 현상이 지속적으로 발생되며, 교량의 지지력이 감소되어 상부구조를 안정적으로 지지할 수 없어 기초지지체가 되는 교각, 교대, 벽체 등이 세굴현상에 의해 침하, 전도 변위 등으로 인하여 구조물이 붕괴될 수 있으므로 기초구조체를 보강하여야 한다.
As the scour phenomenon occurs, the edges of the foundation structures are continuously generated, and since the bearing capacity of the bridge is reduced, it is not possible to stably support the upper structure, so the bridges, shifts, walls, etc., which become the foundation supports, are settled by the scour phenomenon. As the structure may be collapsed due to overturning, displacement, etc., the basic structure should be reinforced.

대한민국 등록특허 제1038723호의 기초구조체의 보강구조물 및 이를 이용한 차수벽 형성, 세굴방지 및 지지력 보강방법은 본 출원인에 의해 기 출원된 것으로서, 기초구조체의 가장자리가 세굴된 부분에 별도의 보강재를 타설하여 보강하되, 추가로 세굴이 발생하는 것을 방지하기 위하여 기초구조체를 둘러싸도록 물막이부재를 추가로 시공하는 기초구조체의 보강방법에 관한 것이다.The reinforcement structure of the foundation structure of the Republic of Korea Patent No. 1038723 and the method of forming the order wall, scour prevention and bearing capacity reinforcement using the same as previously applied by the present applicant, the reinforcement by placing a separate reinforcement on the edge of the foundation structure scoured, In addition, the present invention relates to a method of reinforcing a foundation structure, which additionally constructs a water blocking member to surround the foundation structure to prevent scouring.

특히, 종래의 기초구조체의 보강방법은 물막이부재로서 원통형상의 콘크리트 파일 부재를 다수개 설치함에 따라 다수의 콘크리트파일 부재 끼리 연결하는 공정이 요구되고, 콘크리트 파일부재가 원통형상으로 형성됨에 따라 콘크리트파일 부재와 콘크리트파일 부재가 연속적으로 배치되더라도 여러 작업을 진행하는 중에 콘크리트파일 부재와 콘크리트파일 부재 사이의 틈으로 물이 지속적으로 인입되어 작업성이 떨어지는 문제점이 있다.In particular, the conventional method of reinforcing the basic structure requires a process of connecting a plurality of concrete pile members as a plurality of cylindrical concrete pile members as a water barrier member, and as the concrete pile member is formed in a cylindrical shape, the concrete pile member Even though the concrete pile member is disposed continuously, water is continuously drawn into the gap between the concrete pile member and the concrete pile member during various operations, thereby degrading workability.

그러므로 종래보다 공정과정을 줄이고, 시공품질을 확보하면서 공정 중에도 물이 인입되는 것을 방지할 수 있도록 이루어진 물막이부재가 요구된다.
Therefore, there is a need for a water barrier member that is configured to reduce the process process and to ensure the construction quality compared to the prior art while preventing water from being introduced during the process.

이하에서는 도면을 참조하여 본 발명에 따른 교각의 보강구조물 설치방법에 대한 바람직한 실시예를 설명한다. 본 발명을 설명하기에 앞서 관련된 공지 기능 혹은 구성에 대한 구체적인 설명이 본 발명의 요지를 불필요하게 흐릴 수 있다고 판단되는 경우에는 그에 대한 상세한 설명은 생략한다.Hereinafter, with reference to the drawings will be described a preferred embodiment of the reinforcing structure installation method of piers according to the present invention. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

도 1은 본 발명에 따른 기초구조체의 기초 보강방법의 일실시예를 도시한 순서도이고, 도 2는 본 발명에 따른 기초구조체의 기초 보강방법에서 물막이 부재와 보강부재가 일체로 형성되어 설치된 것을 나타낸 도면이며, 도 3은 본 발명에 따른 기초구조체의 기초 보강방법에 따른 보강구조물이 설치된 것을 도면이다.1 is a flow chart showing an embodiment of a method of foundation reinforcement of the foundation structure according to the present invention, Figure 2 shows that the water barrier member and the reinforcing member is formed integrally formed in the foundation reinforcement method of the foundation structure according to the invention 3 is a view showing that the reinforcing structure is installed according to the method of foundation reinforcement of the foundation structure according to the present invention.

도시된 바와 같이, 기초구조체(P)는 하부의 가장자리(P1)가 물의 유수작용에 의해 패여지게 되므로 내구성이 떨어진다. 그러므로, 기초구조체(P)의 하부에 보강구조물(50)을 설치하기 위하여 도 2에 도시된 바와 같이, 기초구조체(P)의 외측에 기초구조체(P)를 감싸도록 설치되되, 기초구조체(P)와 이격된 위치에 거푸집(20)을 설치한다. As shown, the foundation (P) is inferior in durability because the lower edge (P1) is dug by the flow of water. Therefore, in order to install the reinforcement structure 50 in the lower portion of the foundation structure (P), as shown in Figure 2, the outer structure of the foundation structure (P) is installed to surround the foundation structure (P), the foundation structure (P) Install the formwork 20 at a spaced apart position.

거푸집(20)은 기초구조체(P)를 감싸도록 보강재(55)를 타설하기 위한 것으로서, 보강재(55)가 타설되고 건조되면 철거될 수 있도록 설치된다.(S102)Formwork 20 is to pour the reinforcement 55 to surround the base structure (P), it is installed to be removed when the reinforcement 55 is poured and dried. (S102)

그 후, 기초구조체(P)와 거푸집(20) 사이에는 기초구조체(P)를 둘러싸도록 기초구조체(P)와 이격되게 배치되는 위치에 바닥면(B)을 굴착한다.Thereafter, the bottom surface B is excavated between the base structure P and the formwork 20 at a position spaced apart from the base structure P to surround the base structure P.

여기서, 바닥면은 후술될 물막이부재(30)의 크기에 맞게 굴착되어 물막이부재(30)가 삽입되는 물막이부재 설치부(31)가 형성되도록 한다. 물막이부재 설치부(31)는 소정의 깊이를 갖도록 굴착되는 것이 바람직하다. (S103)Here, the bottom surface is excavated according to the size of the water barrier member 30 to be described later to form a water barrier member installation portion 31 into which the water barrier member 30 is inserted. The water barrier member mounting portion 31 is preferably excavated to have a predetermined depth. (S103)

다음, 굴착된 물막이부재 설치부(31) 및 기초 구조체(P)와 거푸집(20) 사이에 일체로 형성된 물막이부재(30)와 보강부재(33)를 설치한다. 여기서, 물막이부재(30)와 보강부재(33)는 외부에서 미리 별도로 제작되어 굴착이 끝나면 삽입하여 종래와 같이 물막이 부재(30)를 설치하고, 물막이 부재(30)의 내측에 보강부재(33)를 형성한 후, 이들을 연결하는 공종을 생략할 수 있도록 하는 것이 바람직하다.Next, a water barrier member 30 and a reinforcement member 33 which are integrally formed between the excavated water barrier member installation unit 31 and the base structure P and the formwork 20 are installed. Here, the water barrier member 30 and the reinforcement member 33 are manufactured separately in advance from the outside and inserted after the excavation is completed, thereby installing the water barrier member 30 as in the related art, and the reinforcement member 33 inside the water barrier member 30. After forming, it is preferable to be able to omit the work that connects them.

이때, 물막이부재(30)는 물막이부재 설치부(31)의 굴착된 깊이만큼 바닥면 아래로 삽입되어 바닥면보다 아래에 위치됨에 따라 바닥면을 따라 흐르는 물이 물막이부재(30)의 내측으로 인입되지 않도록 차수벽 역할을 수행하고, 보강부재(33)와 물막이부재(30)는 도 2에 도시된 바와 같이, 철근구조물로 형성되어 보강부재(33)가 물막이부재(30)의 내구성이 향상되도록 물막이부재(30)를 지지한다. (S104)At this time, the water barrier member 30 is inserted below the bottom surface by the excavated depth of the water barrier member installation unit 31 and is located below the bottom surface so that water flowing along the bottom surface is not drawn into the water barrier member 30. As shown in FIG. 2, the reinforcing member 33 and the water blocking member 30 are formed of a reinforcing steel structure so that the reinforcing member 33 may improve the durability of the water blocking member 30. Support 30. (S104)

다음, 도 3에 도시된 바와 같이, 기초구조체(P)의 하부 가장자리(P1)의 패여진 부분에는 다수의 주입관(41)의 일측이 삽입되도록 설치된다. 상세하게 설명하면, 주입관(41)은 일측이 기초구조체(P)의 하부 가장자리(P1)에 삽입되고, 타측이 외부로 노출되도록 이루어져, 작업자가 주입관(41)을 통해 교각(P)의 하부 가장자리(P1)의 패여진 부분에 보강재를 타설할 수 있도록 하는 것이 바람직하다.Next, as shown in FIG. 3, one side of the plurality of injection pipes 41 is installed in the recessed portion of the lower edge P1 of the foundation structure P. In detail, the injection pipe 41 has one side inserted into the lower edge P1 of the base structure P, and the other side is exposed to the outside, so that the operator of the piers P through the injection pipe 41 is exposed. It is preferable to be able to pour a reinforcement in the recessed part of the lower edge P1.

또한, 주입관(41)의 일측에는 주입관(41)을 통해 주입된 보강재가 얼마나 주입되었는지 확인하기 위하여 확인관(43)을 더 설치한다. 확인관(43)은 주입관(41)을 통해 주입된 보강재가 기초구조체(P)의 하부 가장자리(P1)에 얼마나 확인하기 위한 것으로서 먼저, 주입관(41)을 통해 보강재를 주입한다. 이때, 주입되는 보강재는 일반적으로 사용되는 콘크리트 등이 사용될 수 있다.In addition, one side of the injection tube 41 is further provided with a confirmation tube 43 to check how much the reinforcing material injected through the injection tube 41 is injected. Confirmation tube 43 is to determine how much the reinforcing material injected through the injection pipe 41 to the lower edge (P1) of the base structure (P), first, the reinforcing material is injected through the injection pipe (41). In this case, the injected reinforcement may be used, such as concrete generally used.

그러면, 작업자는 주입관(41)을 통해 주입된 보강재가 확인관(43)을 통해 인출되는지 여부를 확인한다.Then, the operator checks whether the reinforcing material injected through the injection pipe 41 is drawn out through the confirmation pipe 43.

이때, 보강재가 확인관(43)을 통해 인출되지 않는다면, 작업자는 계속해서 주입관(41)을 통해 보강재를 주입하고, 보강재가 확인관(43)을 통해 인출되기 시작하는 것이 확인되면 보강구조물 설치를 위한 다음 작업을 수행하면 된다. (S105) At this time, if the reinforcing material is not drawn through the check tube 43, the worker continues to inject the reinforcing material through the injection pipe 41, and when it is confirmed that the reinforcing material is drawn out through the check tube 43, the reinforcing structure is installed Here's what you need to do: (S105)

다음, 작업자는 거푸집(20)과 기초구조체(P) 사이에 물막이부재(30)를 커버하도록 보강재(55)를 타설한다. 여기서, 보강재(55)는 일반적으로 사용되는 콘크리트가 될 수 있다. (S106) Next, the worker places the reinforcement 55 to cover the water blocking member 30 between the formwork 20 and the base structure (P). Here, the reinforcing material 55 may be a concrete generally used. (S106)

다음, 작업자는 거푸집(20)을 철거하여 기초구조체의 보강구조물을 완성한다. (S107)Next, the worker demolishes the formwork 20 to complete the reinforcement structure of the foundation structure. (S107)

이에, 이와 같은 기초 구조체 보강방법은 물막이부재와 보강부재가 일체로 형성되고 물막이부재가 굴착된 부분에 삽입되도록 하여 설치됨에 따라 물막이부재와 보강부재를 연결시키는 공종이 줄어드는 장점이 있다.
Thus, the method of reinforcing the basic structure has an advantage in that the work of connecting the water barrier member and the reinforcement member is reduced as the water barrier member and the reinforcement member are integrally formed and installed to be inserted into the excavated portion of the water barrier member.

기초 보강방법의 다른 실시예는 기초구조체(P)를 둘러싸도록 기초구조체(P)와 이격되게 배치되는 위치에 바닥면(B)을 굴착하되, 후술될 물막이부재(30)의 크기에 맞게 굴착되어 물막이부재(30')가 삽입되는 물막이부재 설치부(31)가 형성되도록 한다. (S202)Another embodiment of the foundation reinforcement method is to excavate the bottom surface (B) at a position spaced apart from the base structure (P) so as to surround the base structure (P), it is excavated in accordance with the size of the water barrier member 30 to be described later The water barrier member mounting portion 31 into which the water barrier member 30 'is inserted is formed. (S202)

다음, 물막이부재 설치부(31)에 물막이부재(30')를 삽입하여 설치한다. Next, the water barrier member 30 is inserted into and installed in the water barrier member installation unit 31.

이때, 보강부재(33')는 전술한 바와 같이 철근구조물로 형성되어 물막이부재(30')에 조립되고, 물막이부재(30')는 다수의 원통형 파이를 연결하는 종래와 달리 다수의 패널부재로 이루어져 패널부재의 연결됨에 의해 빈틈없이 설치됨에 따라 바닥면을 따라 흐르는 물이 물막이부재(30')의 내측으로 인입되지 않도록 차수벽 역할과 거푸집의 역할을 동시에 수행할 수 있도록 한다.(S203)At this time, the reinforcing member (33 ') is formed of a reinforcing structure as described above is assembled to the water barrier member (30'), the water barrier member (30 ') is a plurality of panel members unlike the prior art connecting a plurality of cylindrical pie As the panel member is connected by the panel member, the water flows along the bottom surface so as not to be drawn into the water barrier member 30 'so as to serve as the barrier wall and the formwork at the same time.

다음, 기초 보강방법의 일실시예에서와 같이 세굴부분에 보강재를 주입한다.(S204)Next, a reinforcing material is injected into the scoured portion as in the embodiment of the basic reinforcing method.

그 후, 물막이부재(30')의 내측에 기초 구조체(P)를 지지하도록 보강부재(33')를 설치한다. (S205)Thereafter, a reinforcing member 33 'is provided to support the base structure P inside the water barrier member 30'. (S205)

다음, 물막이부재(30')와 기초 구조체(P) 사이에 보강재(55)를 타설한다.(S206)
Next, a reinforcing material 55 is poured between the water barrier member 30 'and the base structure P. (S206)

이에, 이와 같이 이루어진 기초 보강방법의 다른 실시예는 거푸집을 설치하지 아니하고 물막이부재를 패널부재로 형성하여 물막이부재가 거푸집의 역할을 동시에 수행하도록 이루어짐에 따라 거푸집을 설치하는 단계와 이를 철거하는 단계가 생략될 수 있으므로 간단하고 빠르게 기초 구조체를 보강할 수 있다.
Thus, another embodiment of the basic reinforcement method made in this way is to install the formwork and the step of removing the form according to the water barrier member is formed so as to perform the role of formwork at the same time without forming the formwork member as a panel member Since it can be omitted, the foundation structure can be reinforced simply and quickly.

따라서, 전술한 바와 같은 기초 보강방법에 의해 형성되는 보강구조물은 유수작용에 의해 보강구조물의 가장자리가 세굴되더라도 물막이부재(30)가 물의 흐름을 막을 수 있도록 물막이부재를 이용하여 기초구조체를 보강하되 그 공정의 단계가 최소화되어 빠르고 간단하게 기초 구조체를 보강할 수 있어 보강공종이 진행되는 동안 추가적으로 보강구조물이 손상되는 것이 최소화된다.
Therefore, the reinforcement structure formed by the foundation reinforcement method as described above is used to reinforce the foundation structure using the water barrier member so that the water barrier member 30 can prevent the flow of water even if the edge of the reinforcement structure is scoured by the water flow action. The steps of the process can be minimized to quickly and simply reinforce the foundation structure, thereby minimizing additional damage to the reinforcement structure during the reinforcement work.

이상, 본 발명의 일 실시예로 설명하였으나 본 발명의 기술적 사상이 상기 일 실시예로 한정되는 것은 아니며, 본 발명의 기술적 사상을 벗어나지 않는 범주에서 다양한 기초구조체의 보강방법을 구현할 수 있다.
As mentioned above, although the embodiment of the present invention has been described, the technical idea of the present invention is not limited to the above embodiment, and various reinforcement methods of the basic structure can be implemented within the scope without departing from the technical idea of the present invention.
