The invention relates to a precast concrete hollow component, and a manufacturing method thereof, and belongs to the technical field of precast reinforced concrete structural components. The precast concrete hollow component comprises a precast wall plate component, a floor component, a T-shaped wall post component, an L-shaped wall post component, a cross wall post component and a wall body component provided with a hole; the precast concrete hollow component is internally provided with a plurality of longitudinal through holes along the length direction, and a plurality of horizontal non-through holes communicated with the longitudinal through holes along the width direction, wherein the longitudinal through holes are arranged parallelly to each other, and the horizontal non-through holes are arranged parallelly to each other. The manufacturing method comprises following steps: combining templates, such as a bottom die, a top die, a side die, a steel pipe inner die and the like, on a production field of precast slabs; arranging reinforcing meshes; then pouring concrete; drawing out a steel pipe after the strength of the concrete reaches to a certain degree; and dismounting the templates after the concrete reaches to an expected strength degree. The precast concrete hollow component can be used in multilayered, high-rise shear wall and frame-shear wall building structures, thus improving industrial level of the building structures, improving structural behaviors and saving sources.
