地下綜(zong)合(he)管(guan)廊(lang)介紹(shao)地下綜(zong)合(he)管(guan)廊(lang)主(zhu)體(ti)結構(gou)的施工(gong)(gong)(gong)(gong)環(huan)節中，兩者(zhe)的施工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝截然不同，工(gong)(gong)(gong)(gong)期(qi)差別明顯(xian)。預制(zhi)裝(zhuang)(zhuang)配式混(hun)凝土(tu)綜(zong)合(he)管(guan)廊(lang)的主(zhu)體(ti)結構(gou)施工(gong)(gong)(gong)(gong)大部(bu)分在場外完成，管(guan)節的吊裝(zhuang)(zhuang)、拼裝(zhuang)(zhuang)等工(gong)(gong)(gong)(gong)序施工(gong)(gong)(gong)(gong)效率高，所(suo)需(xu)工(gong)(gong)(gong)(gong)期(qi)較短。而現(xian)澆混(hun)凝土(tu)整體(ti)式綜(zong)合(he)管(guan)廊(lang)的主(zhu)體(ti)結構(gou)施工(gong)(gong)(gong)(gong)則全部(bu)在場內完成，占用(yong)了大量現(xian)場工(gong)(gong)(gong)(gong)期(qi)，是總工(gong)(gong)(gong)(gong)期(qi)的重要組成部(bu)分。施工(gong)(gong)(gong)(gong)中一個(ge)標準段(duan)對比，預制(zhi)裝(zhuang)(zhuang)配式混(hun)凝土(tu)綜(zong)合(he)管(guan)廊(lang)的施工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)期(qi)比現(xian)澆混(hun)凝土(tu)整體(ti)式綜(zong)合(he)管(guan)廊(lang)縮短18d左右，縮短近45%工(gong)(gong)(gong)(gong)期(qi)。
