Description

Acrylic template construction device for box culvert concrete Technical Field The invention belongs to the technical field of box culvert construction, and particularly relates to an acrylic template construction device for box culvert concrete. Background Taking the construction of a concrete structure of a box culvert of a highway as an example, in the construction process of the concrete structure of the box culvert, the control on the appearance of the concrete structure of the box culvert is very strict, and the whole appearance quality of the concrete structure of the box culvert is ensured by adopting a mode of brushing a release agent after polishing a template in the prior art. However, due to environmental factors or manual factors, the template is not thoroughly polished, so that the release agent is not uniformly coated, and the appearance of the concrete is far from the requirement. The box culvert concrete control measures in the prior art can control the appearance quality of part of concrete, but the release agent is adopted, so that the construction process is complex, certain harm is produced to the body, each time the template is polished, the environment pollution and the energy consumption are required, the operation procedure is relatively complex, the influence of human and environment is large, and great inconvenience is brought to the construction.
