본 발명은 하수처리장·정수장 구내 하수암거, 하수·오수·폐수 암거, 도로·철도·교량 하부의 배수암거, 택지지구·공업단지내 단지 하수암거, 도심지 빌딩지하 배수암거, 하천복개암거 등의 공사에 적용할 수 있는, 거푸집없이 시공하는 FRP와 콘크리트의 합성체 암거의 시공방법에 관한 것이다.The present invention is for the construction of sewage culverts, sewage, sewage, wastewater culverts, sewage culverts under roads, railroads, bridges, sewage culverts in residential areas, industrial complexes, underground drainage culverts, urban building underground drainage culverts, etc. The present invention relates to a method of constructing a composite culvert of FRP and concrete that can be applied without formwork.

종래의 암거의 시공방법으로는 거푸집을 이용하여 철근 콘크리트 구조체 암거를 시공하는 방법 또는 수로의 일부 구간을 형성하는 암거 유니트를 조립·시공하는 방법 등이 널리 시행되어져 왔다. 거푸집을 이용한 암거의 시공은 현장에서 합판 거푸집을 제작·설치하고 철근을 가공·조립한 후 콘크리트를 타설하여 수로를 형성하고, 콘크리트가 굳으면 관거 내·외부의 거푸집을 해체한 후 콘크리트 표면처리를 하고 흙으로 되메우기를 함으로써 암거 시공을 완료한다. 반면에, 조립식 암거의 시공은 일률적으로 제작된 암거유니트를 터파기 작업이 완료된 작업 구간에 일렬로 정렬시키고, 각각의 암거유니트의 접합부에 에폭시 수지와 같은 접합제를 도포하고, 턴버클 또는 인장케이블 등과 같은 결합수단을 이용하여 각각의 암거유니트를 결합시킨후 흙으로 되메우기를 함으로써 시공이 완료된다.As a conventional method of constructing a culvert, a method of constructing a reinforced concrete structure culvert using formwork or a method of assembling and constructing a culvert unit forming a part of a channel has been widely practiced. For the construction of culverts using formwork, the plywood formwork is manufactured and installed on the site, the rebar is processed and assembled, and concrete is poured to form a waterway. And complete the construction of the culvert by backfilling it with dirt. On the other hand, the construction of the prefabricated culvert is aligned in line with the uniformly manufactured culvert units in the work section of the dig operation, apply a binder such as epoxy resin to the joint of each culvert unit, turnbuckle or tension cable, etc. Construction is completed by combining each culvert unit using the same coupling means and backfilling it with soil.

그러나, 상술한 거푸집을 이용한 암거 시공방법은 거푸집의 조립 및 해체에 상당시간이 소요되며, 거푸집을 해체하기 위해서는 타설된 콘크리트가 굳어질 때까지 최소 3일 정도 기다려야 하므로 작업 공기가 연장되고 작업이 번거로웠다. 또한, 관거의 형상은 현상 타설 콘크리트에 의해 형성되므로 복잡한 형상의 암거를 시공할 때 시공 부주의로 인한 관내부에 유수 장애물이 생성되는 문제점을 안고 있다. 그리고, 암거 유니트를 이용한 시공방법은, 각 암거유니트의 결합에 필요한 결합수단을 구비해야 할 뿐만 아니라, 결합시 강한 인장력을 필요로하기 때문에 시공이 어려운 문제점을 안고 있다.However, the culvert construction method using the above-described formwork takes a considerable time to assemble and dismantle the formwork, and in order to dismantle the form, it is necessary to wait at least 3 days until the cast concrete is solidified, so that the work air is extended and the work is cumbersome. It was. In addition, since the shape of the conduit is formed by developing cast concrete, there is a problem in that a flowing obstacle is generated inside the pipe due to carelessness when constructing a culvert having a complicated shape. In addition, the construction method using the culvert unit has a problem that the construction is difficult because not only the coupling means necessary for the coupling of each culvert unit is required, but also requires a strong tensile force for the coupling.

제1도는 본 발명에 따른 암거의 시공방법에 대한 흐름도로서, FRP와 콘크리트 합성체 암거의 시공방법은 시공계획에 따라 소정 규격 및 형상으로 FRP관체를 제작하는 단계와, 공사 예정구간의 바닥 콘크리트 타설단계와, 바닥 콘크리트상에 FRP관체를 설치하는 단계와, FRP관체에 형성되는 소정 공간에 콘크리트를 타설하는 콘크리트체 형성단계 및 되메우기 단계를 포함하여 이루어 진다.1 is a flow chart for the construction method of the culvert according to the present invention, the construction method of the FRP and concrete composite culvert is the step of manufacturing the FRP pipe to a predetermined size and shape according to the construction plan, and the concrete floor of the construction scheduled section And a step of installing the FRP pipe body on the floor concrete, and a concrete body forming step and refilling concrete in a predetermined space formed in the FRP pipe body.

FRP관체의 제작단계는 시공계획에 따라 공장에서 일괄적으로 수행되며, 유수 수용능력, 수로의 형상 등을 고려하여 수리학적으로 유리하게 FRP관체(1)를 제작한다. 제2도는 본 발명에 따른 FRP관체의 사시도로서, 이를 참조하여 FRP관체의 구조를 상세히 설명한다.The manufacturing step of the FRP pipe is carried out at the factory according to the construction plan, and the FRP pipe (1) is advantageously manufactured hydraulically in consideration of the flow capacity and the shape of the waterway. 2 is a perspective view of the FRP tube according to the present invention, with reference to this will be described in detail the structure of the FRP tube.

FRP관체(1)는 내부 공간을 규정하며 수로를 형성하는 내벽부(11)와, 내벽부의 외측 면과 대응하여 연장 형성되는 외벽부(13) 및 내벽부의 하측에서 외측으로 수평 연장되어 외벽부의 하부에 결합되는 받침면(16)으로 이루어 진다. 이때 내벽부(11), 외벽부(18) 및 받침면(16)에 의해 한정되는 소정 공간이 형성되어 콘크리트 타설 공간이 제공된다.The FRP pipe body 1 defines an inner space and defines an inner wall portion 11 forming a waterway, an outer wall portion 13 extending in correspondence with the outer surface of the inner wall portion, and a horizontal extension from the lower side of the inner wall portion to the outer side, so that the lower portion of the outer wall portion is lower. It consists of a support surface 16 coupled to. In this case, a predetermined space defined by the inner wall portion 11, the outer wall portion 18, and the support surface 16 is formed to provide a concrete pouring space.

내벽부(11)의 길이방향 일단은 다른 FRP관체(1)와 연결될 수 있도록 방사상 외부방향으로 확장되어 단을 형성하는 소켓부(16)가 제공된다. 또한, 수로를 형성하는 내벽부(11)의 단면형상은 수리적으로 유리하게 제작되며 암거의 규모 및 형상에 따라 다양하게 제공될 수 있다.A longitudinal end of the inner wall portion 11 is provided with a socket portion 16 extending radially outward to form a stage so as to be connected to the other FRP tube (1). In addition, the cross-sectional shape of the inner wall portion 11 forming the water channel is advantageously made hydraulically and may be provided in various ways depending on the size and shape of the culvert.

그리고, 바닥 콘크리트상에서 확고히 위치될 수 있도록 접촉 면적을 증가시켜주는 받침면(16)에는 바닥 콘크리트에 돌출 형성된 철근이 통과할 수 있도록 철근공(17)이 제공된다.And, the reinforcing hole 17 is provided on the support surface 16 to increase the contact area so that it can be firmly positioned on the floor concrete to pass the reinforcing bar formed in the floor concrete.

이러한 구성의 FRP관체(1)의 제작단계가 진행되는 동안 현장에서는 바닥 콘크리트 타설단계가 진행된다.While the manufacturing step of the FRP pipe body 1 of this configuration is in progress, the floor concrete pouring step is in progress.

바닥 콘크리트 타설단계에서는 공사 예정구간에 터파기를 하고, 시공 계획에 따라 바닥 철근의 가공조립 및 콘크리트를 타설한다. 이때 바닥 철근중 일부는 상부의 철근과 연결될 수 있도록 위쪽으로 구부려 진다.In the floor concrete pouring phase, the trench is excavated at the scheduled section of construction, and the processing reinforcement of the floor reinforcement and concrete is poured according to the construction plan. At this time, some of the bottom reinforcing bar is bent upwards to be connected to the upper reinforcing bar.

제3도는 본 발명에 따른 암거의 소켓부 접속 상태를 도시한 확대단면도로서, 이를 참조하여 FRP관체의 설치 단계를 설명한다.Figure 3 is an enlarged cross-sectional view showing a socket connection state of the culvert according to the present invention, with reference to this will be described the installation step of the FRP pipe.

바닥 콘크리트의 타설이 완료된 후, 바닥 콘크리트에서 상향 돌출된 바닥 철근이 FRP관체의 철근공(17)을 통과하도록 FRP관체(1)를 위치시킨다. FRP관체의 소켓부(16)는 인접한 FRP관체의 단부에 결합된다. 이어서, 바닥철근과 벽체수직 철근을 연결하고 상부 철근을 조립한다. 이때 사용되는 철근량은 상부하중 등을 고려한다. 철근 조립이 완료되면 FRP관체의 일체화 공정이 수행되는 바, FRP관체의 소켓부(16)와 타단부가 결합되어 형성된 외부접합부(18)에는 FRP액체수지가 주입되고, 내부접합부(19)에는 FRP수지가 도포되어 FRP융합에 의해 인접하는 FRP관체가 서로 일체화된다.After the casting of the bottom concrete is completed, the FRP tube 1 is positioned so that the bottom reinforcing bar protruding from the bottom concrete passes through the reinforcing hole 17 of the FRP tube. The socket portion 16 of the FRP tube is coupled to the end of the adjacent FRP tube. Then, the bottom reinforcing bar and the vertical wall reinforcing bar are connected and the upper bar is assembled. At this time, the amount of rebar used should consider the upper load. When the reinforcing bar assembly is completed, the integration process of the FRP pipe is carried out. The FRP liquid resin is injected into the external joint part 18 formed by combining the socket part 16 and the other end of the FRP pipe body, and the FRP pipe is connected to the internal joint part 19. Resin is applied and adjacent FRP tubes are integrated with each other by FRP fusion.

FRP관체(1)가 일체화되어 연속 정렬되면 관체의 내벽부(11), 외벽부(13) 및 받침면(16)사이에 형성되는 공간내에 콘크리트를 타설하여 콘크리트체(1)를 형성한다.When the FRP pipe body 1 is integrated and continuously aligned, concrete is poured into the space formed between the inner wall part 11, the outer wall part 13, and the support surface 16 of the pipe body to form the concrete body 1.

콘크리트체(2)가 어느정도 굳은후(7-8시간) 흙으로 되메우기하면 FRP와 콘크리트 합성체 암거의 시공이 완료된다.After the concrete (2) has hardened to some extent (7-8 hours), it is backfilled with soil to complete the construction of the FRP and concrete composite culvert.

이상과 같은 FRP와 콘크리트 합성체 암거의 시공방법에 의해 거푸집 설치 및 해체에 소요되는 공기를 단축시키게 되며, 특히 거푸집이 필요하지 않기 때문에 콘크리트가 완전히 굳어질 때까지 기다려 거푸집을 해체한 후 흙을 되메우지 않고, 콘크리트가 어느정도 굳는 7~8시간후 바로 흙을 되메울 수 있으므로 공기를 2일이상 단축할 수 있게 된다. 또한, FRP관체가 공장에서 일괄적으로 제작되기 때문에 복잡한 구조의 암거시공이 가능하게 되며, 시공부주의에 의한 유수장애가 발생되지 않아 우수한 유하능력을 얻을 수 있게 된다. 뿐만 아니라 별도의 결합수단 없이 FRP수지에 의해 FRP관체를 결합할 수 있으므로 보다 간편하게 시공할 수 있게 된다.The construction method of FRP and concrete composite culvert as described above shortens the air required for the installation and dismantling of the formwork.In particular, since the formwork is not needed, wait until the concrete is completely hardened and then remove the form and return the soil. The soil can be refilled immediately after 7-8 hours when the concrete hardens to a certain extent, thus reducing the air for more than two days. In addition, since the FRP pipes are manufactured in a batch at the factory, it is possible to culminate a complex structure, and excellent drainage ability can be obtained because water flow failure due to careless construction does not occur. In addition, since the FRP pipe can be combined by the FRP resin without a separate coupling means can be more easily installed.
