Background technique

Box culverts refer to culverts built with reinforced concrete box-shaped pipe joints. Box culverts are composed of one or more square or rectangular sections, generally made of reinforced concrete or masonry, but reinforced concrete is widely used. When the diameter is less than four meters, box culverts are used. For pipe culverts, reinforced concrete box culverts are a cheap substitute. Piers, abutments, and upper and lower slabs are all poured in the same way. Box culverts are generally cast-in-place, and box culverts in road engineering use The formwork pattern is relatively fixed for the constant-section structure of concrete pouring on site. Due to the long box culvert, the proportion of formwork turnover time in the construction period cannot be ignored.

However, in the prior art, during the pouring of the box culvert, a certain support structure, such as a support frame and formwork, needs to be applied to form and support the pouring of the box culvert. When the strength is reached, it cannot be disassembled, which directly leads to a longer turnaround time of the formwork and the supporting structure, directly leads to an increase in the supply of materials, and increases the construction cost of the box culvert. Therefore, a movable inner formwork of the box culvert is proposed device.
