地(di)下綜(zong)(zong)合(he)管(guan)廊介紹地(di)下綜(zong)(zong)合(he)管(guan)廊主(zhu)體(ti)結構的施工(gong)(gong)(gong)(gong)環節(jie)中，兩者的施工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝截(jie)然(ran)不同，工(gong)(gong)(gong)(gong)期(qi)(qi)差別(bie)明顯(xian)。預制裝(zhuang)(zhuang)配式(shi)(shi)混(hun)(hun)凝土(tu)綜(zong)(zong)合(he)管(guan)廊的主(zhu)體(ti)結構施工(gong)(gong)(gong)(gong)大(da)部分(fen)在場(chang)外(wai)完成，管(guan)節(jie)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)(qi)較短。而現(xian)(xian)澆(jiao)混(hun)(hun)凝土(tu)整體(ti)式(shi)(shi)綜(zong)(zong)合(he)管(guan)廊的主(zhu)體(ti)結構施工(gong)(gong)(gong)(gong)則全部在場(chang)內完成，占用了大(da)量現(xian)(xian)場(chang)工(gong)(gong)(gong)(gong)期(qi)(qi)，是總工(gong)(gong)(gong)(gong)期(qi)(qi)的重要組成部分(fen)。施工(gong)(gong)(gong)(gong)中一個標準段對(dui)比，預制裝(zhuang)(zhuang)配式(shi)(shi)混(hun)(hun)凝土(tu)綜(zong)(zong)合(he)管(guan)廊的施工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)期(qi)(qi)比現(xian)(xian)澆(jiao)混(hun)(hun)凝土(tu)整體(ti)式(shi)(shi)綜(zong)(zong)合(he)管(guan)廊縮(suo)短18d左右，縮(suo)短近45%工(gong)(gong)(gong)(gong)期(qi)(qi)。
