TTYJ900t穿隧式运架一体机施工技术的应用

The Construction Technology Application of TTYJ900t Tunneling All-in-one Machine

本文通过对穿隧式运架一体机架设箱梁施工的应用进行了分析,总结了穿隧式运架一体机"过隧低位运梁、隧道口零距离架梁、桥间路基快速转场"等施工技术,在工程设计与施工等方面起到了指导作用。

This article carries on the analysis of the box girder construction application of tunneling al-in-one machine, and summarizes the tunneling all-in-one machine construction tec-hnology of＂low girder beam across tunnel, zero distance set b-eam in the tunnel portal, and the rapid transitions of bridge and subgrade＂, which plays a guiding role in the aspects of the eng-ineering design and construction technology.
