Sewage treatment plant, water purification plant Sewage culvert. sewer. Waste water. Wastewater culvert. road. railroad. Drainage culvert at the bottom of the bridge. Residential land. Only sewage culvert in industrial complex. Downtown underground drainage culvert. Can be applied to the construction of river culvert and culvert. Composite culvert of FRP and concrete to be constructed without form
The present invention relates to a composite body culvert comprising FRP and concrete which can be installed without a form by placing concrete in the FRP pipe body.;The composite culvert of FRP and concrete according to the present invention comprises an inner wall portion 3 defining an inner space forming a channel and a space formed by spacing a predetermined distance from the side wall of the inner wall portion and integrally formed with the lower end of the inner wall portion An FRP tube (1) including an outer wall part (5) joined thereto; And a concrete body (6) placed between the inner wall part and the outer wall part.;Composite culvert of FRP and concrete of this structure can be used to construct the culvert without form to shorten the air and increase airtightness, corrosion resistance and sewage throughput according to FRP characteristics.
