The invention discloses a transporting protective pushcart used for building construction and preventing a pipe from rolling down. The transporting protective pushcart used for building construction and preventing the pipe from rolling down comprises a plate body, a cavity, a limiting plate, reserved grooves and stopping plates; an abutting piece is fixed at the lower end of the right side of theplate body; the cavity is formed in the plate body; a first stabilizing plate is mounted on the surface of the internal upper end of the cavity; the first stabilizing plate is connected with a secondstabilizing plate through a connecting shaft; the plate body is connected with a vertical plate through a connecting shaft on the right side; a drawing rod is welded at the upper end of the vertical plate; the limiting plate is connected with the plate body through a rotating shaft; a connecting plate is mounted at the upper end of the limiting plate; a mounting block is fixed at the front end ofan elastic net; the reserved grooves are formed in the surface of the vertical plate in an equally-spaced manner; the stopping plates are welded on the surfaces of the two sides of the upper end of the plate body; and a pipe body is arranged at the lower end of the elastic net. According to the transporting protective pushcart used for building construction and preventing the pipe from rolling down, the elastic net made of a nylon material conveniently presses and covers the pipe body, the situation that the pipe slides off due to internal loosening is avoided, and the structure is stable.
