The transverse ventilation system needs to perform an equal quantity ventilation from the blow and exhaust hole which was installed in the tunnel. These hole is equipped with the quantity adjustment board, the theoretical static pressure distribution for which it asks by calculation are compared with survey static pressure distribution, and the blow hole opening is tuned finely. The conventional coefficient used for the calculation of the opening had large deviation with this tunnel duct form, and it was expected that adjustment work is accompanied by difficulty. Our company performs examination of a coefficient by the degree adjustment work of blow hole opening in Nagoya Expressway Public Corporation / Higashiyama Tunnel, and since it carried out the degree calculation of blow hole opening and local adjustment which were based more on the actual condition.
