Title:
SPRAY SYSTEM FOR LOWERING TEMPERATURE INSIDE TUNNEL
Document Type and Number:
Japanese Patent JP2015113586
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To realize a mist spray capable of achieving both of suppression of temperature rise in a tunnel and securement of a visual environment for a driver using the inside of the tunnel.SOLUTION: A spray system for lowering temperature inside a tunnel sprays water in the form of mist from a spray nozzle (10) inside the tunnel as a semi-closed space, and suppresses temperature rise inside the tunnel while securing a visual environment. A mist spray section is divided into a plurality of sections, and a hygrometer is installed in a boundary of each of the sections or is installed in correspondence with the sections so that spray to one section on the windward side of the hygrometer, a measurement value of which exceeds a prescribed value, is stopped.
