The invention discloses a manhole / hand well forced ventilation cloth curtain and a using method thereof. The ventilation cloth curtain consists of frame rods (1), panel buckles (2), vertical rods (3), prefabricated fireproof cloth (4), balance weight rods (5), fixing belts (6), supporting feet (7) and transverse rods (8). The frame rods (1), the prefabricated fireproof cloth (4), the balance weight rods (5) and the fixing belts (6) form a cloth curtain, and the vertical rods (3), the supporting feet (7) and the transverse rods (8) form a support frame to achieve supporting and fixing effects. The panel buckle (2) is fixed on the frame rods (1). The positions, close to the middles, of the vertical rods (3) are punched, the frame rods (1) of the cloth curtain component are installed on the tops of the vertical rods (3) and the punched positions, and the prefabricated fireproof cloth (4) between the frame rods (1) forms a windward side. The supporting feet (7) are in a T shape, the vertical rods (3) are inserted into the supporting feet from top to bottom, the transverse rods (8) penetrate from the bottoms of the supporting feet, and the effect of expanding the supporting range is achieved.
