地(di)下綜(zong)合(he)(he)管廊(lang)(lang)介紹地(di)下綜(zong)合(he)(he)管廊(lang)(lang)主(zhu)體(ti)(ti)結構的(de)施工(gong)(gong)(gong)(gong)環節中，兩者(zhe)的(de)施工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝截然不(bu)同，工(gong)(gong)(gong)(gong)期差別明顯。預制(zhi)裝(zhuang)(zhuang)配(pei)式混凝(ning)(ning)土綜(zong)合(he)(he)管廊(lang)(lang)的(de)主(zhu)體(ti)(ti)結構施工(gong)(gong)(gong)(gong)大部(bu)(bu)分(fen)在(zai)場(chang)(chang)外完成，管節的(de)吊裝(zhuang)(zhuang)、拼裝(zhuang)(zhuang)等(deng)工(gong)(gong)(gong)(gong)序施工(gong)(gong)(gong)(gong)效率(lv)高(gao)，所需工(gong)(gong)(gong)(gong)期較(jiao)短。而現(xian)澆(jiao)混凝(ning)(ning)土整(zheng)體(ti)(ti)式綜(zong)合(he)(he)管廊(lang)(lang)的(de)主(zhu)體(ti)(ti)結構施工(gong)(gong)(gong)(gong)則全(quan)部(bu)(bu)在(zai)場(chang)(chang)內完成，占用(yong)了大量(liang)現(xian)場(chang)(chang)工(gong)(gong)(gong)(gong)期，是總(zong)工(gong)(gong)(gong)(gong)期的(de)重要組成部(bu)(bu)分(fen)。施工(gong)(gong)(gong)(gong)中一個標準段對比(bi)，預制(zhi)裝(zhuang)(zhuang)配(pei)式混凝(ning)(ning)土綜(zong)合(he)(he)管廊(lang)(lang)的(de)施工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)期比(bi)現(xian)澆(jiao)混凝(ning)(ning)土整(zheng)體(ti)(ti)式綜(zong)合(he)(he)管廊(lang)(lang)縮短18d左(zuo)右，縮短近45%工(gong)(gong)(gong)(gong)期。
