The Application of the TY Fuel Additive to Reducing Air Pollution in the Tunnel which is being Constructed

Objective To reduce air pollution in the tunnel which is used the method of trackless transport to construct.Methods Use TY fuel additive to promote the fuel burning more sufficiently.Results Each average density of CO、NO_x and exhausted smoke in the culvert has been reduced by 46%,55%,42%.The determination values have extreme significant difference(P<0.001)after tested by variance analysis in statistics.Conclusion In the meantime of installing ventilation systems in the culverts,using fuel additive to improve the construction environment has very feasible significance in current construction condition of Chian.
