수중보는 물의 흐름 속도를 낮추기 위해 물속에 일부가 잠기게 설치되는 구조물로, 하천이나 강에 설치되어 수위를 일정하게 유지하는 기능, 다시 말해서 물의 속도를 낮추는 둑의 기능을 수행함으로써 상류와 하류의 물이 섞이지 않게 한다.
Submarine is a structure that is partially submerged in water to reduce the flow rate of water. It is installed in a river or river to maintain a constant water level, that is, to function as a weir to lower the speed of water. Do not mix this.

그런데 종래의 하천 수중보는 하천 바닥을 굴착한 다음, 거푸집 설치, 철근조립, 콘크리트 타설 및 양생, 거푸집 해체 등의 공정을 거쳐 시공이 완료되기 때문에 공사기간이 길고 시공방법이 복잡하며 공사 중 홍수 발생 시 공사자재가 하천에 떠내려가 수질오염을 야기하는 문제점이 있다.
However, the conventional river underwater beam is excavated the bottom of the river, and then the construction is completed through the process of installing the formwork, reinforcing steel bars, concrete placing and curing, and dismantling the form, so the construction period is long and the construction method is complicated, and when the flood occurs during construction There is a problem that the construction materials float in the river causing water pollution.

본 발명은 상기한 종래 기술의 문제점을 해결하기 위해 안출된 것으로서, 시공기간의 단축을 가능하게 하고 수중보 시공에 의해 발생가능한 수질오염을 최소화할 수 있는 조립식 하천 수중보를 제공하는데 그 목적이 있다.
The present invention has been made to solve the problems of the prior art, it is an object of the present invention to provide a prefabricated river underwater beam that can shorten the construction period and minimize the water pollution that can be caused by underwater construction.

상기 목적을 달성하기 위하여, 본 발명은, 단면의 형상이 사다리꼴이고 수평방향으로 내부가 천공되며 그 천공된 내부와 연통되는 주입공이 상부에 형성되되, 모서리부에 형성된 통공으로 삽입되는 연결봉을 통해 상호간에 고정되고 측벽에 의해 양측 개방면이 밀폐되며 하천 상류 및 하류 사이에 배치되는 복수개의 PC(Polymer Concrete) 박스와; 상기 PC 박스의 천공된 내부에 배치가능한 입체적인 형상을 갖고 주입공을 통해 그 PC 박스로 인입되는 콘크리트에 매설되는 철근보강재;로 구성되는 것을 특징으로 한다.
In order to achieve the above object, the present invention, the cross-sectional shape is trapezoidal and the inner perforated in the horizontal direction and the injection hole communicating with the perforated inside is formed at the top, the mutually through the connecting rod inserted into the through-hole formed in the corner portion A plurality of PC (Polymer Concrete) boxes fixed to the sidewalls and sealed at both sides by the sidewalls and disposed between the stream upstream and downstream; Reinforced reinforcement material having a three-dimensional shape that can be disposed in the perforated interior of the PC box is embedded in the concrete introduced into the PC box through the injection hole.

여기서 상기 PC 박스 하부에는 하천 하류측으로 수평하게 연장되는 수평부와, 상기 수평부 끝단으로부터 수직하게 연장되는 수직부로 이루어진 낙차물받이부가 더 구비되며, 상기 PC 박스의 상류측면과 수직부 측면에는 복수개의 돌이 상호간에 고정된 상태에서 그물망으로 둘러쌓인 돌붙임 블록이 배치되는 것을 특징으로 한다.
Here, the lower portion of the PC box is further provided with a drop receiving portion consisting of a horizontal portion extending horizontally downstream of the stream, and a vertical portion extending vertically from the end of the horizontal portion, a plurality of stones on the upstream side and the vertical side of the PC box It is characterized in that the stone block is enclosed by a net in a fixed state between each other.

Figure 2 is a view showing a PC box of the prefabricated river underwater beam according to the present invention, Figure 3 is a view schematically showing the construction process of the prefabricated river underwater beam according to the present invention.

상기 PC 박스(100)는 사다리꼴 형상의 단면을 갖고 수평방향으로 내부가 천공되고 그 천공된 내부와 연통되는 주입공(101)이 상부에 형성되되, 모서리부에 형성된 통공(102)으로 삽입되는 연결봉(110)을 통해 상호간에 고정되고 측벽(10)에 의해 양측 개방면이 밀폐되는 구조를 갖는다.
The PC box 100 has a trapezoidal cross section and is formed with an injection hole 101 formed in an upper portion thereof in a horizontal direction and communicating with the punched inside, and inserted into a through hole 102 formed at an edge portion thereof. It is fixed to each other via 110 and has a structure in which both open surfaces are sealed by the side wall (10).

이와 같은 구조에 따르면, 상기 PC 박스(100) 자체가 일종의 거푸집 역할을 수행할 수 있음에 따라 공장 제작 이후에 하천 현장으로 운반 및 배치될 수 있어, 결과적으로 수중보 공기 단축과 수질오염 발생 확률을 감소시킬 수 있게 된다.
According to such a structure, since the PC box 100 itself can play a form of formwork, it can be transported and arranged after the plant production to the river site, resulting in shortening the underwater beam air and reducing the probability of water pollution. You can do it.

또한 횡방향에 따른 하천 끝단에 대향되는 측벽(10)을 시공한 다음으로 순차적으로 일측 측벽(10)으로부터 타측 측벽(10)을 향해 PC 박스(100)를 배치하면서 연결봉(110)으로 복수개의 PC 박스(100)를 상호간에 고정시키는 과정에 따라 그 PC 박스(100)의 전체적인 배치가 이루어지며, 처음과 마지막으로 배치된 PC 박스(100)의 양측면은 대향되는 한 쌍의 측벽(10)에 의해 밀폐되어 복수개의 PC 박스(100) 모두의 천공된 내부가 밀폐된 상태로 유지된다.
In addition, a plurality of PCs are connected to the connecting rods 110 while constructing the sidewalls 10 facing the end of the river along the transverse direction, and sequentially arranging the PC box 100 from one sidewall 10 toward the other sidewall 10. The overall arrangement of the PC box 100 is made according to a process of fixing the boxes 100 to each other, and both sides of the first and last PC boxes 100 arranged by the pair of side walls 10 are opposed to each other. Closed and the perforated interior of all of the plurality of PC boxes 100 is kept closed.

상기 철근보강재(200)는 PC 박스(100)의 천공된 내부에 배치가능한 입체적인 형상을 갖고 주입공(101)을 통해 그 PC 박스(100)로 인입되는 콘크리트에 매설됨으로써 PC 박스(100)로 인입되는 콘크리트의 인장력을 향상시키기 위한 것으로, 바람직하게는 PC 박스(100)의 단면과 같은 사다리꼴 형상을 갖도록 좌우종횡 방향으로 철근이 용접된다. 참고로 콘크리트는 레미콘을 통해 직접 투입되거나 현장에서 직접 제작된 콘크리트를 종래의 펌핑 수단을 사용하여 PC 박스(100)로 투입된다.
The reinforcement reinforcement 200 has a three-dimensional shape that can be disposed in the perforated interior of the PC box 100 and is embedded in the concrete that is introduced into the PC box 100 through the injection hole 101 is drawn into the PC box 100 In order to improve the tensile force of the concrete to be, preferably the reinforcing bar is welded in the left and right longitudinal and transverse direction to have a trapezoidal shape, such as the cross section of the PC box 100. For reference, concrete is directly injected through the ready-mixed concrete or concrete produced directly on-site to the PC box 100 using a conventional pumping means.

이에 따라 상기 PC 박스(100)와 철근보강재(200)는 콘크리트를 통해 전반적으로 일체화된 상태로 고정되게 된다.
Accordingly, the PC box 100 and the reinforcement reinforcement 200 are fixed to the overall integrated state through the concrete.

한편으로 상기 PC 박스(100) 하부에는 하천 하류측으로 수평하게 연장되는 수평부(121)와 그 수평부(121) 끝단으로부터 수직하게 연장되는 수직부(122)로 이루어진 낙차물받이부(120)가 더 구비된다.
On the other hand, the lower portion of the PC box 100, the drop portion 120 consisting of a horizontal portion 121 extending horizontally to the downstream side of the river and a vertical portion 122 extending vertically from the end of the horizontal portion 121 is further It is provided.

여기서 상기 수평부(121)는 PC 박스(100)의 위쪽을 따라 흐르는 하천수가 월류 낙하되는 부분에 위치됨으로써 하천바닥이 세굴되는 것을 방지함과 동시에 하천 저면에 PC 박스(100)가 접촉되는 면적을 확장시켜 보다 안정적으로 PC 박스(100)가 하천 내 배치된 상태를 유지하도록 하기 위한 것이고, 수직부(122)는 이하 기술되는 돌붙임 블록(300)을 지지하기 위해 구비되는 것이다.
Here, the horizontal portion 121 is located at the portion of the stream water flowing along the upper portion of the PC box 100 to prevent the riverbed from being scoured and at the same time the area where the PC box 100 is in contact with the bottom of the river The expansion is to more stably maintain the PC box 100 is disposed in the river, the vertical portion 122 is provided to support the stone block 300 described below.

추가적으로 상기 PC 박스(100)의 상류측면과 수직부(122) 측면에는 하상 바닥의 세굴을 방지하고 수중보 시공에 따른 공사자재가 떠내려가는 것을 방지하기 위한 돌붙임 블록(300)이 배치되는데, 이러한 돌붙임 블록(300)은 복수개의 돌이 상호간에 접착제를 통해 고정된 상태에서 그물망으로 둘러쌓인 것으로, 돌 사이의 틈으로는 하천수의 통수가 가능하여 하천수의 흐름을 방해하지 않으므로 그 틈보다 더 큰 크기의 이물질이 돌붙임 블록(300)을 통과하지 않게 되고 돌붙임 블록(300)의 하중에 의해 하천바닥의 세굴현상이 방지된다.In addition, the upstream side and the vertical portion 122 side of the PC box 100 is provided with a stone block block 300 to prevent scouring of the bottom of the lower floor and to prevent the construction materials from drifting due to underwater construction. Attachment block 300 is a plurality of stones are enclosed in a net in a state fixed through the adhesive between each other, the gap between the stones can be passed through the river water because it does not interfere with the flow of the river water of a larger size than the gap Foreign matter does not pass through the stone block 300 and scour phenomenon of the riverbed by the load of the stone block 300 is prevented.
