Study Of The Construction And Maintenance Of Speed-Lift Switch

The construction method to replace the existing switch by speed-lift switch,is described for operating rail line .Based on and conserve experience ,the repair rules and methods are given for speed-lift switch being used ,which may build the strengthen project,stabilities the technically predicament,and prolong the repair period . All of those had remarkable effects on the practices of maintenance.To maximize the structure strength and track framework rigidity of speed-lift switch,the standardized method of lay ,the preparation project before the construction and the problems construction as the result are the made out though the analyses of the design factors and structure of. the beforehand lay quality of is stabile.The paper begins with the investigation of the location of current switches analyses the technical factors of locale collocation,the traveling crane requirements and switches. And then the location design of is optimized,which makes the not only meet with the technical standards but also decrease the cost the rep-aeration of operating equipments.The paper details the construction safety,technique and organization methods from some aspects such as the location,the pushing process,and the labor distribution. It is promised the perfect accomplishment of engineering construction may reach by optimizing theconstruction program,and that a better economy effectmay get through reasonably decomposing the working procedure and alloy of work force.Combining the rules of conserve railroad equipments,with the structure and the force peculiarity of . to stability the switch fundament as fast as possible,and sustain the structure strength and track framework rigidity ,the check method ,repair period and item of are discussed. Furthermore,the problems how to bring into play the technical character of in the and operation...
