본 발명은 중공식 교각 배수구조에 관한 것으로, 특히 시공중의 우수나 시공 후 교각 내외부 온도차에 의한 결로를 배수시키기 위한 중공식 교각 배수구조에 관한 것이다.The present invention relates to a hollow pier drainage structure, and more particularly to a hollow pier drainage structure for draining condensation due to rain or rain during the construction and the temperature difference inside and outside the pier.

일반적으로 중공식 교각의 하부구조는 도 1에 도시된 바와 같이, 기초(1) 위에 교각(2)을 구축하되, 교각(2)의 내부에는 중공홀(3)이 형성된다.In general, as shown in FIG. 1, the hollow structure of the hollow piers has a piers 2 formed on the foundation 1, and a hollow hole 3 is formed inside the piers 2.

이때 교각(2)은 한 번에 콘크리트를 타설하여 시공하는 것이 아니라 교각(2)의 높이에 따라 여러 번에 걸쳐 콘크리트를 타설 및 양생하여 시공한다.At this time, the pier (2) is not constructed by placing concrete at a time, but by placing and curing concrete several times depending on the height of the pier (2).

따라서, 교각(2) 시공중 우천으로 인해 중공홀(3)에 물이 고이거나 또는 중공홀(3) 내외부의 온도차에 의한 결로로 인해 물이 고이는 것을 방지하기 위해 중공홀(3)에는 별도의 배수관(4)이 설치된다.Therefore, in order to prevent water from accumulating in the hollow hole 3 due to rainy weather during construction of the piers 2 or condensation due to condensation due to a temperature difference between the inside and the outside of the hollow hole 3, the hollow hole 3 has a separate structure. The drain pipe 4 is installed.

그리고 상기 중공홀(3)의 내부에는 지면보다 일정 정도 높게 콘크리트를 타설하여 버림콘크리트(5)를 형성하여 중공홀(3)의 하부로 물이 고이는 것을 방지토록 한다.And the inside of the hollow hole (3) to cast concrete to a certain degree higher than the ground to form the discarded concrete (5) to prevent the water is accumulated in the lower portion of the hollow hole (3).

상기한 바와 같은 구성으로 이루어진 종래의 중공식 교각은 별도로 중공홀(3) 하부에 콘크리트를 타설하여 버림콘크리트(5)를 형성하므로 콘크리트 타설에 따른 추가비용이 발생되고, 중공홀(3) 내 콘크리트 타설로 인하여 기초(1)에 막대한 상재하중이 작용하여 기초(1)에 손상을 가져올 뿐만 아니라 특히 기초(1)가 말 뚝기초인 경우에는 파일의 개수가 늘어나므로 공사비가 전반적으로 증가되는 문제점이 있다. The conventional hollow piers made of the above-described configuration separately casts concrete in the bottom of the hollow hole 3 to form the discarded concrete 5 so that an additional cost is generated according to concrete pouring, and the concrete in the hollow hole 3 is Due to the heavy load applied to the foundation (1) due to the casting, it not only damages the foundation (1) but also increases the overall construction cost because the number of piles increases, especially when the foundation (1) is pile foundation. have.

이에, 본 발명은 상기한 바와 같은 제문제점을 해결하기 위해 안출된 것으로서, 중공식 교각의 중공홀 내부에 고이는 물을 용이하게 배수시키도록 한 중공식 교각 배수구조를 제공하는데 그 목적이 있다.Accordingly, an object of the present invention is to provide a hollow pier drainage structure for easily draining water that accumulates inside the hollow hole of the hollow pier to solve the problems as described above.

상기한 목적을 달성하기 위한 본 발명에 따른 중공식 교각 배수구조는 내부에 중공홀을 갖는 중공식 교각 배수구조에 있어서, 상기 중공홀의 하부에 일정한 두께를 갖는 투수재를 설치하고, 상기 투수재의 하부에 집수된 물을 외부로 배수시키기 위하여 소정의 경사각을 가지도록 설치되면서, 중공홀의 측벽을 관통하여 배수관이 설치된 것을 특징으로 한다.Hollow pier drainage structure according to the present invention for achieving the above object in the hollow pier drainage structure having a hollow hole therein, to install a water permeable having a constant thickness in the lower portion of the hollow hole, the lower portion of the water permeable It is installed to have a predetermined inclination angle to drain the water collected in the outside, characterized in that the drain pipe is installed through the side wall of the hollow hole.

이하, 본 발명을 첨부한 예시도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

도 2는 본 발명에 따른 기초바닥면 중공식 교각 배수구조를 도시한 단면도이다.Figure 2 is a cross-sectional view showing a foundation bottom hollow pier drainage structure according to the present invention.

이 도면에 도시된 바와 같이, 본 발명에 따른 중공식 교각 배수구조는 내부에 중공홀(3)을 갖는 중공식 교각 배수구조에 있어서, 상기 중공홀(3)의 하부에 일정한 두께를 갖는 투수재(6)를 설치하고, 상기 투수재(6)의 하부에 집수된 물을 외부로 배수시키기 위하여 소정의 경사각을 가지도록 설치되면서, 중공홀(3)의 측벽을 관통하여 배수관(4)이 설치된 구조이다.As shown in this figure, the hollow pier drainage structure according to the present invention is a hollow pier drainage structure having a hollow hole (3) therein, a water permeable having a constant thickness below the hollow hole (3) (6) and installed to have a predetermined inclination angle in order to drain the water collected in the lower part of the water permeable material (6) to the outside, the drain pipe (4) is installed through the side wall of the hollow hole (3) Structure.
