随着隧道工程各工序施工技术的日趋成熟,铺底作业的施工机械化技术也在不断更新换代,传统的组合式弧形模板施工工艺,正逐步被更为方便快捷的机械化施工所替代。本文以黔张常铁路施工为例,阐述隧道机械化作业对工程降造的影响。机械化作业关键技术(一)自行式仰拱栈桥+配套弧形模板采用40m自行式液压仰拱栈桥,减少了掌子面开
With the maturing of construction technology in all tunneling processes, the construction mechanization technology of bottoming work is constantly being replaced. The traditional combined arc-shaped template construction technology is being gradually replaced by more convenient and quick mechanized construction. This article takes Qian Zhang-Chang Railway construction as an example to illustrate the influence of tunnel mechanization on engineering construction. Mechanized operation of key technologies (A) self-inverted arch trestle + supporting curved template 40m self-propelled hydraulic trestle bridge to reduce the face opened
