Summary:A long-distance horizontal hole concrete pouring device solves the problem that long-distance holes are not completely filled with concrete. The device comprises a concrete feeding device and a vacuumizing connector, a discharge hole of the concrete feeding device is communicated with the preformed hole; and the vacuumizing joint is communicated with the hole. Municipal comprehensive pipe galleries, underground passages and subway stations are gradually subjected to large-scale pipe jacking construction, the structure adopts prefabricated assembly components, the construction method is used for a certain pipe jacking underground excavation subway station, and in the project, the construction is carried out strictly according to specifications, design requirements and construction process key points in the concrete construction process of vacuumizing and pouring duct piece reserved holes, and the construction efficiency is greatly improved. And the concrete pouring quality of the project is guaranteed, and the
