Description

현장타설형 조립식 암거Cast-in-place prefabricated culvert

본 발명은, 조립식 암거에 관한 것으로서, 보다 상세하게는, 바닥부를 현장에서 그라우팅 타설성형되도록 함으로써, 물류비용을 점감할 수 있으며 시공을 용이하게 할 수 있도록 한 조립식 암거에 관한 것이다.The present invention relates to a prefabricated culvert, and more particularly, to a prefabricated culvert that can reduce the logistics cost and facilitate construction by allowing the bottom portion to be grouted in the field.

암거는 우수·오수 및 농공업용수 등의 수로를 형성하거나, 인도 및 차도 등의 통행로를 만드는데 사용되는 한편, 전기통신 및 온·냉관로 등의 매설을 위한 지하공동구의 제작 및 농수산물의 저장창고 등의 제작 등에 다양하게 사용되고 있다.Culverts are used to form waterways of stormwater, sewage and agricultural industry, or to create passageways such as sidewalks and driveways, while underground underground areas for laying telecommunications, hot and cold pipelines, and storage of agricultural and marine products. It is widely used for production.

특히, 암거를 부분별로 분할하여 예를 들면, 덮개판, 측면판, 바닥판 등을 공장에서 다량으로 미리 제작하고, 현장에서 이들이 조립되도록 함으로써, 공기를 단축할 수 있을 뿐만 아니라, 경제적 시공이 가능하도록 한 조립식 암거가 널리 이용되고 있다.In particular, by dividing the culvert into parts, for example, cover plate, side plate, bottom plate, etc. are produced in advance in a large amount in the factory, so that they can be assembled in the field, not only shorten the air, but also economical construction is possible Prefabricated culverts are widely used.

암거를 덮개판, 측면판 그리고 바닥판으로 나누어 제작하는 조립식 암거의 예로서, 측면판의 전후방에는 사다리꼴형 결합돌조를 돌설하고, 그 중심부에 투입공과 연통되게 밀폐접합층을 형성하여 상호 결합시키는 조립식 암거가 대한민국 실용신안공보 공고번호 제85-28호에 알려져 있다.As an example of the prefabricated culvert that divides the culvert into cover plate, side plate and bottom plate, the prefabricated claw is formed with a trapezoidal coupling protrusion in the front and rear of the side plate, and forms a hermetically sealed layer in communication with the input hole at the center thereof. The culvert is known from Korean Utility Model Publication No. 85-28.

그런데, 이러한 종래의 조립식 암거에 있어서는, 바닥판, 측면판 및 덮개판을 모두 공장에서 미리 제작하여 설치현장으로 이송하여야 하므로 제작 및 운반이 용이하지 않을 뿐만 아니라, 현장에서 이들을 시공할 때에도 비교적 많은 장비 및 인원이 소요되는 단점이 있다.By the way, in the conventional prefabricated culvert, all the bottom plate, side plate and cover plate must be manufactured in advance in the factory and transported to the installation site, which is not only easy to manufacture and transport, but also relatively large amount of equipment when constructing them on site. And there is a drawback in the number of people.

따라서, 본 발명의 목적은, 운반비용을 절감시킬 수 있으며 시공을 간편하게 할 수 있는 조립식 암거를 제공하는 것이다.Accordingly, it is an object of the present invention to provide a prefabricated culvert that can reduce transportation costs and simplify construction.

이와 같이, 상부판과; 저부영역에 수평방향을 따라 연장된 저부플랜지가 형성되어 있으며, 상기 상부판의 양단을 각각 접촉지지하는 접촉지지부가 형성된 측벽부재를 공장에서 미리 제작하여 현장에서 조립되도록 하고, 상기 저부플랜지와 인접되도록 대향배치된 저부플랜지사이에 현장에서 그라우팅을 타설하여 후그라우팅부가 형성되도록 함으로써, 바닥판을 공장에서 제작하여 현장으로 운반하던 종래와는 달리 운반을 용이하게 할 수 있으며 운반비용이 절감된다. 또한, 암거유니트의 바닥부를 현장에서 그라우팅 타설성형하게 됨으로써, 암거유니트의 조립설치가 용이하고 측벽부 및 중간측벽부가 일체로 연결되어 전체적인 암거결합체의 내구성이 향상되게 된다.As such, the top plate; A bottom flange extending along the horizontal direction is formed in the bottom region, and a side wall member having contact support portions for supporting both ends of the top plate is fabricated in advance in a factory to be assembled in the field, and adjacent to the bottom flange. By placing grouting in the field between the oppositely arranged bottom flanges to form a post grouting part, unlike the conventional production of the bottom plate at the factory and transporting to the site, it is easy to transport and the transport cost is reduced. In addition, by grouting the molding of the bottom of the culvert unit in the field, it is easy to assemble and install the culvert unit and the side wall portion and the middle side wall portion is connected integrally to improve the durability of the overall culvert assembly.

전술 및 실시예에서는 중간측벽부의 중앙영역에 연통부를 마련하여 설명하고 있지만, 인접배치되는 다른 중각측벽부와의 상호 인접영역에 상호 협조적으로 연통부가 형성되도록 할 수 있다. 또한, 연통부의 형상도 사각형상이외의 다른 형상을 가질수 있음은 물론이다.In the above-described embodiments, the communication unit is provided in the central region of the intermediate side wall portion, but the communication portion can be cooperatively formed in mutually adjacent areas with other intermediate side wall portions disposed adjacent to each other. In addition, of course, the shape of the communication portion may have a shape other than the rectangular shape.

그리고, 측벽부재의 하단에 수평방향을 따라 연장된 내측플랜지부 및 외측플랜지부를 구성하여 설명하고 있지만, 외측플랜지부는 현장상황에 따라 형성하지 않을 수 도 있다.The inner flange portion and the outer flange portion extending in the horizontal direction at the lower end of the side wall member are described, but the outer flange portion may not be formed depending on the site situation.

이상 설명한 바와 같이, 본 발명에 따르면, 운반비용을 절감시킬 수 있으며 시공을 간편하게 할 수 있는 조립식 암거가 제공된다.As described above, according to the present invention, there is provided a prefabricated culvert that can reduce the transportation cost and simplify the construction.
