The invention discloses a gas sleeve for penetrating a wall and going out of the ground. The sleeve penetrates the interior of a wall body or the ground. The gas sleeve comprises an inner pipe used for conveying gas, and an outer pipe arranged outside the inner pipe in a sleeving manner. The gas pipe and the steel sleeve are concentrically arranged. Sealing layers blocked by bituminous mortar are arranged at the two ends of the gas pipe. A filling layer formed by bituminous batched jute is arranged between the sealing layers, and close nipples are arranged at the two ends of the gas pipe. According to one purpose, the gas sleeve for penetrating the wall and going out of the ground is uniform in filling, not likely to rust, efficient in mounting and long in service life. According to the other purpose, a preparation method of the gas sleeve for penetrating the wall and going out of the ground is provided, and the method is designed aiming at manufacturing of the sleeve. 本发明公布了种用于穿墙、出地面燃气套管，所述套管穿过墙体或者地面内部设置，包括用
