Manual adjustment cannot ensure that the pouring time is consistent for each concreting area, and it is difficult to ensure that the concrete is poured evenly onto the surface of the building's top. In the later stages, a lot of manual labor is required to smooth the concrete poured onto the building's top, which reduces work efficiency.

[0004] Therefore, in this application, a concreting device for a prefabricated segmental beam is proposed to solve the above-mentioned problems. CONTENTS OF THE PRESENT UTILITY MODEL
