Manufacturing method of non-standard prestressed hollow slab

The invention provides a manufacturing method of a non-standard prestressed hollow slab. The manufacturing method comprises the steps that a mold cavity for pouring is included, prestressed tendons are tensioned in the mold cavity, end sleeves are arranged on the two opposite side walls of the mold cavity in a penetrating mode, and the inner ends of the end sleeves extend into the mold cavity and are used for forming hole channels in the ends of the non-standard prestressed hollow slab; a central sleeve is arranged in the die cavity, a supporting pipe sequentially penetrates through the end sleeve at one end of the die cavity, the central sleeve and the end sleeve at the other end of the die cavity, and the central sleeve and the end sleeves connected with the two ends of the central sleeve are kept on the same straight line; concrete is poured and vibrated in the membrane cavity; before final setting of the concrete, the supporting pipes are pulled out of the center sleeve and the end sleeves; the end sleeve
