Claims

[Scope of Claim for Utility Model Registration] 1. A paper having an outer diameter approximately equal to the inner diameter of the manhole cover receiving frame and inscribed in the manhole cover receiving frame on a concrete horizontal support frame to define the inner peripheral surface of the entrance of the manhole. a cylindrical tube; and a plurality of cylindrical tubes, each having an abutting edge at its inner end and fixed on a horizontal support frame on the outside of the cylindrical paper tube, with the abutting edge in contact with the outer surface of the cylindrical paper tube. A positioning plate, a connecting hole formed in a mounting collar provided around a receiving frame of a manhole cover, and a connecting rod that extends vertically between the positioning plates and connects the receiving frame to the positioning plate. Concrete pouring equipment for manholes. 2. A paper tube having an outer diameter approximately equal to the inner diameter of the manhole cover receiving frame and inscribed in the manhole cover receiving frame on a concrete horizontal support frame to define the inner peripheral surface of the entrance of the manhole; and an inner end portion. and a sliding guide groove on the upper surface that supports both ends of the nut and holds the nut slidably in the outward and outward directions, and the abutting edge is connected to the outer surface of the paper tube. a plurality of positioning plates fixed on the horizontal support frame outside the paper tube in contact with the manhole cover, a connecting hole formed in the mounting collar provided around the receiving frame of the manhole cover, and a connection hole between the positioning plates. A manhole concrete pouring construction device comprising: a connecting rod that extends vertically between the rods and connects the receiving frame to the positioning plate by screwing a male screw formed at the lower end of the rod into a nut provided on the positioning plate; .
