大直径盾构施工多编组长距离轨道运输关键技术研究

Study on the Key Technology of Multi-Group and Long-Distance Rail Transportation in Large Diameter Shield Construction

根据大型盾构机施工现场的实际需要和以往施工经验的对比数据,研究并实施了大直径盾构机多编组长距离轨道运输关键技术。通过对多编组长距离轨道运输编组和运行组织采取有针对性的运输技术保障措施,研究并实施了在运渣量巨大的情况下多编组长距离轨道运输施工方案,在大直径盾构机掘进出渣时,保障多编组轨道设备能在长距离运输状况下达到安全、稳定、快速的运输作业状态,所取得的经验可为类似隧道轨道运输项目提供借鉴和参考。

According to the actual needs of the large-scale shield construction site and the comparative data of the previous construction experience,the key technology of multi-group and long-distance rail transportation of the large-diameter shield is studied and implemented.By taking targeted transportation technical guarantee measures for the formation and operation organization of multi-group and long-distance rail transportation,the construction scheme of multi-group and long-distance rail transportation is studied and implemented under the condition of huge amount of slag transportation.When the slag is dug out as large diameter shield machine works,the multi-group rail equipment can achieve safe,stable and fast transportation operation under the condition of long-distance transportation.The experience obtained can provide reference for similar tunnel projects of rail transportation.
