Light prefabricated underground comprehensive pipe gallery

The invention relates to the technical field of underground pipe galleries, in particular to a light prefabricated underground comprehensive pipe gallery which comprises a pipe gallery prefabricated unit, a longitudinal temporary rib, a prestressed rib unit, a circumferential sealing rubber strip, a pipe gallery detection unit and a pipe gallery control unit. By adopting the arc-shaped side wall, the stress on the cross section of the prefabricated comprehensive pipe gallery is more reasonable, the thickness of the side wall can be effectively reduced, and the dead weight of the pipe gallery is reduced. Each pipe gallery prefabricated unit is formed by transversely abutting two cabin body units, so that construction and hoisting are more convenient; the prestressed tendons are adopted to effectively reduce cracks of the top flat plate and the bottom flat plate, so that the durability of the structure can be improved, and the thicknesses of the top flat plate and the bottom flat plate can be reduced; and by us
