900t运架一体机隧道口零距离架设技术研究

摘要

It is relatively complex to construct the high-speed railway bridge,the problems such as erecting at zero-dis-tance in bridge-tunnel connection section are often encountered.The conventional erecting costs long time and with difficul-ty in construction and high safety risk.This paper analyzed the actual situation,and carried out an innovation of the regular zero-distance beam erection.According to the condition,the temporary outrigger hold hoop and roller were adopted instead of the auxiliary guide beam design.It could shorten the construction time,simplify the procedure and improve the safety.%高铁架梁施工，工况一般比较复杂，经常遇到桥隧相连的零距离梁架设问题。常规架设方式架设时间长，施工难度大，安全风险高。对工况实际情况进行分析，并对常规零距离梁架设进行了改进创新，根据工况去除了使用辅助导梁的设计，改换临时支腿抱箍及滚杠，缩短施工时间，简化施工步骤、提高施工安全。
