PURPOSE:To eliminate air extracting work at the site of construction and permit to construct in a short period of time by a method wherein the fluid flowing mat is filled previously with high soluble gas at a factory or the like. CONSTITUTION:The fluid flowing mat is constituted by a method wherein pillar- like terminal devices 4A, 4B, formed with cavities 3 communicated with respective flow paths 1, are connected to both ends of a flat plate-like piping section 2, formed with a plurality of flow paths 1 for circulating the fluid therethrough. The high soluble gas is sealed into the mat previously at the factory or the like. Ammonia, hydrogen chloride, carbon dioxide or the like, for example, may be employed as the high soluble gas. At the site of construction, a hose of supplying side, which is filled with water to a part immediately before a connecting part, is connected to an entrance 5A to introduce the water into the fluid flowing mat. When the water is introduced, the high soluble gas in the fluid flowing mat is absorbed into the water rapidly and the inside of the mat is filled with the water instead of the high soluble gas. After the mat is filled with the water, an exit 5B is opened and the hose of discharging side is connected thereto. According to this method, the air extracting work at the site of construction may be eliminated. |
