The invention provides a rapid cooling system for a high-ground-temperature long tunnel. The rapid cooling system comprises a heat insulation sealing layer, an air supply system and a water supply system, wherein the air supply system comprises a surface air cooler, an air supply fan, an air return fan, an air return three-way pipe, an air supply three-way pipe, an air return adjustable flow valve, a first air supply pipe and an air return pipe; the first air supply pipe penetrates through the heat insulation sealing layer to supply cooled air to a tunnel face area; the air return pipe also penetrates through the heat insulation sealing layer; the air return three-way pipe communicates with the air supply three-way pipe; the air return adjustable flow valve is arranged on the air return three-way pipe; the water supply system comprises a refrigerator, a water supply pipeline and a water supplementing pipeline; and the refrigerator communicates with connectors at the two ends of an inner cavity of a liquid pipeline on the surface air cooler through the water supply pipeline and the water supplementing pipeline. The safe and rapid tunnel cooling effect is achieved, cooled cold air isleft in a main construction operation area on the inner side of the heat insulation sealing layer, and constructors can have a comfortable construction environment.
Description
technical field [0001] The invention belongs to the technical field of tunnel engineering, and in particular relates to a rapid cooling system for long tunnels with high ground temperature. Background technique [0002] With the needs of my country's economic development, the speed of infrastructure construction is also steadily advancing, and many of the projects involve the construction of tunnels. During the construction of long tunnels, in a semi-enclosed environment and in an environment with abundant underground heat sources, the construction of long tunnels is easily affected by high ground temperature. Excessively high temperatures in the tunnel will directly affect the safety of construction personnel and construction equipment. Safety. [0003] In order to reduce the temperature of the face area of the tunnel under construction so that the construction can proceed normally, some directly use water spray to cool down, but the hot and humid environment also does n...
