A steel chamber used as a manhole of a steam pipeline is provided to maintain an internal environment of the steel chamber in an optimum condition by installing a ventilation funnel. A steel chamber used as a manhole of a steam pipeline includes a steel chamber body(110), a disk-like floor sheet(120), a cover sheet(130), an inlet pipe(140), a manhole lid(145), and a ventilation funnel(170). The steel chamber body is made of steel in a cylindrical shape with a top opened. The steel chamber has a condensed water collecting unit integrally mounted in the inside of the cylindrical body. The disk-like floor sheet is attached to a bottom surface of the steel chamber body and has an area larger than the bottom surface of the steel chamber body. The cover sheet covers the opened top to hermetically seal the steel chamber. The condensed water collecting pipe is connected to the cover sheet. The inlet pipe has a ladder(270) attached to one side of an inner surface of the inlet pipe. The manhole lid is coupled with the steel chamber body to be opened and closed. |
