RHEDA 2000®1617Installation techniquesMaximum precision during installation ensures exactand long-lasting track positioningThe great majority of the bi-block sleepers of the RHEDA 2000® systemare produced locally in especially constructed production plants.This arrangement reduces transport costs to a minimum. As a result of thesimple installation technology, which does not require special equipment,local track and civil-engineering companies can install the RHEDA 2000®. Inaddition, a surveying technique especially developed for the RHEDA 2000®system assures great exactness of track position and geometry. The alignmenttechniques used here – using spreader bars and spindle-base adjustmentunits – enable precise alignment and securing of the track panel, evenunder the most unfavourable of construction-site installation conditions.The spreader-bar adjustment system involves a combined technique consistingof the following two elements: vertical adjustment by means ofspindles attached at the ends of the sleepers, and horizontal adjustmentby special spreader bars at the centre of the sleepers. The spindle adjustmentsupports the track panel directly at the rail base and enables bothvertical as well as horizontal track-panel alignment.With both techniques, the adjustment procedures are completed with approvalgranted by the survey engineer. The next step includes the castingof the sleepers into a track concrete layer. Here, two measured points onthe rail may at intervals of 5 m have position or height differences of noGeneral overview of RHEDA 2000® production sequences, consisting of manual and mechanised steps of workPreparation ofthe substructureAssembly of thetrack panelRough alignmentof the track panelInstallation ofthe track formworkEmbankmentPlacing of the frost protection layerusing conventional constructionmachinesPlacing of the hydraulically bondedlayer using conventional constructionmachinesAssembly on sitePlacing reinforcementPlacing of single sleepers and installationof track reinforcementInstallation of rails (temporary or final)Manual rough alignmentLifting and rough alignment of the trackpanel using manual devices (rail jacks,track alignment frames, etc.) and surveyinstrumentsPossible kinds of formworkIndividually / manually (on site) manufacturedformwork (e.g., timber formwork)Pre-fabricated formwork system elements(usually of steel)Pre-fabricated (steel) formwork systemelements with integrated rails forconstruction vehiclesCivil structures• Preparation of the civil structuresurface and the possible track fixationelements according to the individualsub-/superstructure designPre-assemblyPre-assembly of the track panels onspecial sitesTransport and placing of the completetrack panels to the final installationlocationAutomatic rough alignmentLifting and rough alignment of the trackpanel using automatic devices: e.g.,rough alignment machines, remotelycontrolled by electronic surveyinginstrumentsLOGISTIC ACTIVITIES

The top-down installationprocedure inherent to this system can optimally satisfy these exactingrequirements. Production of special sleepers by RAIL.ONE – with manufactureand installation of the RHEDA 2000® system by local constructioncompanies – allows optimal economical cost/benefit relationship: both forRAIL.ONE as well as for the local industry.Final alignment ofthe track panelPlacing of the trackconcreteSupplementaryworking stepsVertical final alignmentVertical final alignment using the verticaladjustment spindles of the spindlebracketsAlignment of the required superelevation,with adjustment of the proper angle ofthe base plates of the spindle bracketsManual concrete placingManual concrete placing using concretebucket and craneManual concrete placing using concretepumpConcrete curingWetting of the concrete surfaceCoating of the concrete surface withcuring liquidCovering of the concrete surface withplastic or textile sheetsHorizontal final alignmentHorizontal final alignment using thehorizontal adjustment screws of thespindle bracketsAutomatic concrete placingConcrete placing using an automaticconcrete placing unit: e.g.,concreting unitAvoiding stress in unset concreteLoosening of the rail fasteningsLOGISTIC ACTIVITIES
