地(di)(di)下(xia)綜(zong)合(he)(he)管廊(lang)介紹地(di)(di)下(xia)綜(zong)合(he)(he)管廊(lang)主(zhu)體結構的施(shi)工(gong)(gong)環節中(zhong)，兩者的施(shi)工(gong)(gong)工(gong)(gong)藝截然不同(tong)，工(gong)(gong)期差別明顯。預制裝配式(shi)混(hun)凝土(tu)綜(zong)合(he)(he)管廊(lang)的主(zhu)體結構施(shi)工(gong)(gong)大部(bu)分(fen)在場外(wai)完(wan)成，管節的吊裝、拼裝等(deng)工(gong)(gong)序施(shi)工(gong)(gong)效(xiao)率高，所需工(gong)(gong)期較短。而(er)現(xian)澆混(hun)凝土(tu)整(zheng)體式(shi)綜(zong)合(he)(he)管廊(lang)的主(zhu)體結構施(shi)工(gong)(gong)則全部(bu)在場內完(wan)成，占用了大量現(xian)場工(gong)(gong)期，是(shi)總工(gong)(gong)期的重要(yao)組(zu)成部(bu)分(fen)。施(shi)工(gong)(gong)中(zhong)一個標準段(duan)對比(bi)，預制裝配式(shi)混(hun)凝土(tu)綜(zong)合(he)(he)管廊(lang)的施(shi)工(gong)(gong)工(gong)(gong)期比(bi)現(xian)澆混(hun)凝土(tu)整(zheng)體式(shi)綜(zong)合(he)(he)管廊(lang)縮短18d左右，縮短近45%工(gong)(gong)期。
