地(di)下綜(zong)合(he)管廊(lang)(lang)(lang)介紹地(di)下綜(zong)合(he)管廊(lang)(lang)(lang)主(zhu)體結構(gou)的施(shi)(shi)(shi)工(gong)環(huan)節(jie)中，兩者(zhe)的施(shi)(shi)(shi)工(gong)工(gong)藝截(jie)然不(bu)同，工(gong)期(qi)(qi)差別明顯(xian)。預(yu)制裝配式混凝(ning)土綜(zong)合(he)管廊(lang)(lang)(lang)的主(zhu)體結構(gou)施(shi)(shi)(shi)工(gong)大(da)部分在(zai)場(chang)外完成，管節(jie)的吊裝、拼裝等工(gong)序施(shi)(shi)(shi)工(gong)效(xiao)率高(gao)，所(suo)需工(gong)期(qi)(qi)較(jiao)短。而(er)現澆(jiao)混凝(ning)土整體式綜(zong)合(he)管廊(lang)(lang)(lang)的主(zhu)體結構(gou)施(shi)(shi)(shi)工(gong)則全部在(zai)場(chang)內完成，占用了大(da)量現場(chang)工(gong)期(qi)(qi)，是總工(gong)期(qi)(qi)的重要組(zu)成部分。施(shi)(shi)(shi)工(gong)中一個標準段對比(bi)，預(yu)制裝配式混凝(ning)土綜(zong)合(he)管廊(lang)(lang)(lang)的施(shi)(shi)(shi)工(gong)工(gong)期(qi)(qi)比(bi)現澆(jiao)混凝(ning)土整體式綜(zong)合(he)管廊(lang)(lang)(lang)縮短18d左(zuo)右(you)，縮短近45%工(gong)期(qi)(qi)。
