城市轨道交通停车场及车辆段库内立柱式检查坑整体道床的无轨施工工艺

Trackless Construction Technology of Pillar Inspection Pit Monolithic Track Bed in Urban Rail Transit Parking Lot and Depot

分析了城市轨道交通停车场及车辆段库内立柱式检查坑常规施工工艺存在的交叉施工干扰影响大,质量控制难,劳动强度大,工效低等缺点。介绍了立柱式检查坑无轨施工方法的新工艺,根据扣配件的尺寸加工精密的模具,减少施工单位交叉施工,土建仅负责轨道梁及立柱式预留纵筋施工,其余施工工序均由铺轨单位完成,此施工工艺较大地提高了施工工效,降低了人工架轨的劳动强度,节约工装成本,能较好地控制施工质量。

The disadvantages of regular construction technology of urban rail transit parking lot and depot pillar inspection pit include large disturbance of cross-construction,difficult quality control,high labor intensity,and low efficiency.The innovative technology of pillar inspection pit trackless construction is introduced:according to the size of buckle accessories,precise mold is produced to reduce the cross-construction among construction units.Civil construction is only responsible for the construction of track beams and pillar-reserved longitudinal bars.The rest of the construction processes are completed by the paving units.This construction process greatly improves construction efficiency,reducing labor intensity of artificial rails and saving cost of workmanship,which keeps construction quality in better control.
