기초구조체의 보강구조물 및 이를 이용한 차수벽 형성, 세굴방지 및 지지력보강방법 { Reinforcement structure of footing body and Reinforcement method using this building cutoff collar, scouring protection and supporting }Reinforcement structure of footing body and Reinforcement method using this building cutoff collar, scouring protection and supporting}

본 발명은 기초구조체의 보강구조물에 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 보강구조물을 형성하고, 이를 이용하여 기초구조체의 차수벽 형성, 세굴방지 및 지지력 보강하는 기초 구조체의 보강방법에 관한 것이다.
The present invention relates to a reinforcing structure of 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. To form a reinforcement structure of the foundation structure that can prevent additional scouring and increase the bearing capacity of the foundation structure after the new reinforcement. It is about a method.

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 9에 도시된 바와 같이, 강이나 하천 바닥에 세워지기 때문에 흐르는 강물이나 하천에 의한 유수작용에 의해서 한계소류력 이상이 되면 기초구조체(P)의 가장자리(P1)가 점차 쓸려 패여나가는 세굴현상이 발생한다.As shown in FIG. 9, since the foundation is built on the river or river bottom, the edge P1 of the foundation structure P is gradually swept away when the limit flow force is exceeded by the flow of the river or the river. Scour occurs.

이러한 세굴현상이 일어난 기초구조체의 가장자리가 패여나가는 현상이 지속적으로 발생될 수 있으므로 교량의 지지력이 감소되어 내구성이 떨어지므로 기초지지체를 안정적으로 지지할 수 없어 기초지지체가 되는 교각, 교대, 벽체 등이 세굴현상에 의해 침하, 전도 변위 등으로 인하여 무너질 수 있는 문제점이 있으므로 기초구조체를 보강하여야 한다. Since the edges of the foundation structure where the scour phenomenon occurs can be continuously generated, the bearing capacity of the bridge is reduced and the durability is lowered. Therefore, the bridges, shifts, walls, etc. that become the foundation supports cannot be stably supported. Since there is a problem that can be collapsed due to sinking, conduction displacement, etc. due to scour phenomenon, the foundation structure should be reinforced.

이러한 세굴현상이 발생되어 가장자리가 패여진 기초구조체의 하부에는 기초구조체의 하부 즉, 가장자리를 감싸도록 추가 보강재를 타설한다.Such scouring occurs, and the bottom of the foundation structure in which the edge is dug, an additional reinforcement is poured to surround the bottom of the foundation structure, that is, the edge.

그런데, 종래의 이러한 기존의 기초구조체에 추가 보강재를 타설하는 것은 흐르는 물에 의해 추가로 타설된 보강재에도 지속적으로 세굴현상이 발생하는 문제점이 있다.However, in the case of placing the additional reinforcement to the existing existing basic structure there is a problem that the scour phenomenon occurs continuously to the reinforcement further poured by the flowing water.

또한, 기존의 세굴현상이 발생된 기초구조체의 패인 부분을 그대로 두고 추가 보강재만 타설하기 때문에 지속적으로 세굴현상이 발생됨에 따라 추가로 타설된 추가 보강재도 기초구조체를 안전하게 지지할 수 없는 문제점이 있다.
In addition, since the additional stiffening occurs continuously because only the additional reinforcement is poured while leaving the indented portion of the existing structure in which the existing scour occurs, the additional reinforcement that is additionally poured may not be able to safely support the basic structure.

본 발명은 상술한 문제점을 해소시키기 위하여 안출된 것으로서 본 발명이 해결하려는 과제는 기초구조체의 하부 가장자리에 유수작용이 발생하는 것을 방지하는 기초구조체의 보강구조물을 제공하는 것이다.SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and the problem to be solved by the present invention is to provide a reinforcing structure of the base structure to prevent the flow of water occurs on the lower edge of the base structure.

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 reinforcing material may be used, such as commonly used concrete. (S105)

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. (S107)
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: (S107)

도 7은 본 발명에 따른 기초구조체의 보강구조물을 설치하기 위한 보강부재 설치단계 및 보강재 타설단계를 나타낸 도면이고, 도 8은 본 발명에 따른 기초구조체의 보강구조물을 설치하기 위한 거푸집 제거단계 및 구조체지지부재 철거단계를 나타낸 도면이다.Figure 7 is a view showing the step of installing the reinforcing member and reinforcing member for installing the reinforcing structure of the foundation structure according to the present invention, Figure 8 is a formwork removing step and structure for installing the reinforcing structure of the foundation structure according to the present invention Figure showing the removal of the support member.

도시된 바와 같이, 보강재가 주입되어 기초구조체(P)의 하부 가장자리(P1)의 파여진 부분을 보강하고 나면, 작업자는 거푸집(20)과 기초구조체(P) 사이에 다수의 보강부재(55)를 설치한다. 보강부재(55)는 철근과 같이 보강구조물이 내구성을 갖도록 설치된다. As shown, after the reinforcement is injected to reinforce the excavated portion of the lower edge P1 of the foundation structure P, the operator has a number of reinforcement members 55 between the formwork 20 and the foundation structure P. Install it. The reinforcing member 55 is installed such that the reinforcing structure has durability, such as reinforcing bars.

이때, 물막이부재(30)의 상부로 돌출된 물막이보강부재(33)와 다수의 보강부재(55)를 연결하여 물막이부재(30)의 내구성도 강화시키도록 한다.At this time, the water barrier reinforcing member 33 and the plurality of reinforcing members 55 protruding to the upper portion of the water barrier member 30 are connected to enhance the durability of the water barrier member 30.

또한, 물막이부재(30)에는 물막이부재(30)와 물막이부재(30) 사이를 연결하는 연결보강부재(51)가 더 설치되어 물막이부재(30)의 내구성을 더욱 강화시키는 것이 바람직하다.(S108)
In addition, the water barrier member 30 is further provided with a connection reinforcing member 51 for connecting between the water barrier member 30 and the water barrier member 30 to further enhance the durability of the water barrier member 30. (S108 )

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. (S109)
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. (S109)

다음, 작업자는 도 8에 도시된 바와 같이, 최초에 설치하였던 구조체 지지부재(10)를 철거하여 기초구조체의 보강구조물을 완성한다.
Next, as shown in FIG. 8, the worker dismantles the structure supporting member 10 that was originally installed to complete the reinforcing structure of the basic structure.

이와 같은 과정을 통해 설치된 보강구조물은 유수작용에 의해 보강구조물의 가장자리가 세굴되더라도 어느 정도 세굴된 후 물막이부재(30)가 노출되면, 물막이 부재(30)가 물의 흐름을 막게 되므로 더 이상 세굴현상에 의해 추가적으로 보강구조물이 손상되는 것이 방지되고, 기초구조체의 지지력이 증대되는 것이다.
The reinforcement structure installed through the above process is scoured to some extent even though the edge of the reinforcement structure is scoured by the flowing water, and then the water barrier member 30 is exposed, the water barrier member 30 prevents the flow of water. By this, additional damage to the reinforcement structure is prevented, and the bearing capacity of the foundation structure is increased.
