Large-dip-angle trash rack one-time forming suspension type sliding formwork and construction method

The invention discloses a large-dip-angle trash rack one-time forming suspension type sliding formwork and a construction method. The large-dip-angle trash rack one-time forming suspension type sliding formwork comprises a formwork body system and a suspension system; the formwork body system comprises trash rack-shaped formworks formed by splicing panels, and reinforcing ribs and supporting trusses are arranged between the formworks; a working platform is laid on the upper surface of the formwork body system; a hydraulic control system is arranged on the working platform; the suspension system comprises a suspension supporting frame of a truss structure, and the suspension supporting frame is fixed to a trash rack upper platform through anchor bars and steel supports; a plurality of groups of suspension pull rods are connected below the suspension supporting frame; the bottom ends of the suspension pull rods are connected with a truss of the formwork body system through hydraulic jacks; the suspension angle of the suspension pull rods is consistent with the inclination angle of the trash rack; a concrete conveying system is arranged above the formwork body system along the installed steel bars and the installed rails; and a defect elimination maintenance system is connected below the formwork body system. The large-dip-angle trash rack one-time forming suspension type slidingformwork has the characteristics that steel bars are bound in place at a time, grid grooves and rails are installed at a time, second-stage concrete construction is omitted, and one-time forming is achieved through a suspension type sliding formwork.
