[0002] A rainwater box culvert is a drainage facility installed under buildings such as roads, bridges, and tunnels. It is similar to a large underground reservoir. Its main function is to store rainwater on rainy days, thereby playing a role in drainage. When there is too much rain, if a rainwater box culvert is not installed, it is easy to cause water accumulation on the road and even cause urban waterlogging and floods. Rainwater box culverts can effectively store rainwater, prevent water flow from exceeding the carrying capacity of the pipeline, reduce the burden on the urban drainage system, and reduce the occurrence of floods.

[0003] The traditional method of rainwater box culvert construction is a secondary casting process, that is, one part is cast first, and after the construction of this part is completed, the other part is constructed. The secondary casting process will result in construction joints, which reduces the waterproofing effect. At the same time, the secondary casting process will also increase the construction progress.
