碩士 === 中華科技大學 === 土木防災工程研究所在職專班 === 99 === Can renew the use already to have the land to plan the conformity, reduces the environmental pollution, the noise…And so on. Along with the engineering technology evolution, quarrels the mixed obsolete rail transportation system the urban district to dial moves to (railroad underground), namely nowadays government administration delivery targets, when railroad underground, the environment is moist and the tunnel percolating water the railroad produces the barrier to transport business, stops besides the structure division use leaks the medicinal preparation, to lead Shui Ban to design the improvement; Outside the high-pressured contact wire use an insulating sleeve prevent reason drive pipe prevents and controls partially; In 1984 started so as to actual surface Switzerland Furer+Frey Corporation to design the use conductor rail to solve railway electrification each problem, the time can the promotion tunnel high pressure electrical power system stability and reduces influence of the tunnel structure water leakage, only then could improve the execution smoothly. This research utilization literature review way, compared with between the pyrocondensation drive pipe, the water conduit and the conductor rail the difference, the research discovered the tunnel structure water leakage place uses frequently the foaming agent does not have the corrosive factor, must causes the contact wire to corrode has reason of the copper wire corrosion resultant phenomenon. Nowadays in has built is open to traffic cable car of line group part the road section, uses leads the water board way solution present leakage question, but future, if may use the conductor rail equipment, but effective put an end to tunnel percolating water to harm of the contact wire, but enhances the high-voltage cotton thread large scale stable and reliability.
