The invention provides a cast-in-place hollow floor system using a steel mesh and inflatable tube combination box for pore-forming. The cast-in-place hollow floor system is composed of a main beam, a ribbed beam, an upper flange plate, a lower flange plate and the steel mesh and inflatable tube combination box. The main beam is a reinforced concrete combination beam or a fashioned iron beam. The steel mesh and inflatable tube combination box is formed by interacting a steel mesh and inflatable tubes. The steel mesh forms a box top, a box bottom and two side walls of the combination box. According to the inflatable tubes, plastic is made into air storage tubular bodies or polystyrene blocks to form the other two side walls of the steel mesh and inflatable tube combination box and the height of the inner space of the supporting box top and the box bottom.
