[0002] The utility corridor is an underground urban pipeline corridor. It builds a tunnel space underground in the city or factory, and integrates various engineering pipelines such as electricity, communication, gas, heating, water supply and drainage. The main structure is a long-distance continuous construction. The utility corridor project mostly adopts the open-cut cast-in-place construction method, that is, the ground is first dug up, and the main concrete of the utility corridor is poured using traditional formwork in the open air, and then covered and backfilled.

[0003] At present, with the continuous development of modern construction projects, the requirements for construction efficiency, quality and safety are getting higher and higher. In the field of corridor construction, the traditional formwork construction method has many disadvantages, such as long construction period, high labor intensity, serious material waste, etc. Summary of the invention
