Because different culvert formwork construction projects have different conditions and requirements, it is not good to make a more detailed construction plan for you directly. However, according to the current construction situation, its construction technology is generally survey and lofting → foundation pit excavation → bearing capacity test → foundation treatment → foundation and bottom plate (reinforcement installation, formwork installation, concrete pouring and maintenance) → wall reinforcement installation, formwork installation and concrete pouring → cover plate reinforcement installation, formwork installation and concrete pouring. Quality control generally includes two aspects, namely, control items: concrete strength (meeting the design requirements), plane position (20mm in the light and 50mm in the dark), bottom elevation (20 mm) and section size (meeting the design requirements; The other is appearance control: the surface is straight and smooth, and the settlement joints are neat and vertical, running through from top to bottom.
