The pouring sequence is to pour the bottom plate concrete first, then the web plate concrete, and finally the wing plate concrete. The pouring thickness of each layer should not exceed 30 cm. The discharge in the two side webs should be balanced to avoid displacement caused by eccentric compression of the inner mold, which leads to uneven thickness of the web plate concrete. After each layer is vibrated, the next layer is distributed. The interval between the two layers should not be greater than the initial setting time of the concrete. The pouring speed is reduced in the steel dense area of the end anchor pad. After the web plate concrete is poured, a set time is set to allow the web plate concrete to fully settle, and then the wing plate is poured.

A highway T-beam production line according to claim 1, characterized in that, It also includes a T-beam formwork grinding and cleaning device, which comprises an electric walking mechanism, a side and top grinding mechanism, and a bottom grinding mechanism. Two side and top grinding mechanisms are used, symmetrically installed on both sides of the electric walking mechanism for grinding the inner side and top surfaces of the T-beam's side molds. Two bottom grinding mechanisms are used, symmetrically installed on the front and rear sides of the electric walking mechanism for grinding the bottom mold of the T-beam's traveling trolley. The electric walking mechanism is installed on the bottom mold of the traveling trolley. It also includes a first blowing and dust suction mechanism and a second blowing and dust suction mechanism. The first blowing and dust suction mechanism is installed on one side of the side and top grinding mechanisms to blow and suction the ground template surface. The second blowing and dust suction mechanism is installed between the two bottom grinding mechanisms to blow and suction the ground template surface.

10. A highway T-beam production line according to claim 9, characterized in that, The side and top grinding mechanism includes a first grinding disc, a first grinding frame, a first telescopic frame, a second grinding disc, a second grinding frame, a bending lifting frame, and a second telescopic frame. The first grinding disc is arranged in multiple staggered rows and is rotatably connected to the upper bent first grinding frame and driven to rotate by a first drive mechanism. The multiple rows of first grinding discs are arranged in a bent structure, which can cover the concave side and inclined top surface of the bottom of the side mold. The first grinding frame is fixedly connected to the first telescopic frame, which is mounted on an electric walking mechanism. The second grinding disc is arranged in multiple staggered rows and is rotatably connected to the second grinding frame and driven to rotate by a second drive mechanism. The multiple rows of second grinding discs can cover the upper vertical section of the side mold and, after bending, can cover the wing plate mold fixedly connected to the top of the side mold. The second grinding frame is fixedly connected to the bending lifting frame, which is used to lift and rotate the second grinding frame above the wing plate mold. The bending lifting frame is mounted on the second telescopic frame, which is fixedly connected to the electric walking mechanism. Both the first grinding disc and the second grinding disc are made of metal brushes.
