地下綜(zong)(zong)(zong)合(he)管廊(lang)(lang)介紹地下綜(zong)(zong)(zong)合(he)管廊(lang)(lang)主體結構(gou)的施(shi)(shi)工(gong)(gong)(gong)(gong)環節中(zhong)(zhong)，兩(liang)者的施(shi)(shi)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝截然不(bu)同，工(gong)(gong)(gong)(gong)期(qi)差別明顯(xian)。預制裝配(pei)式(shi)混凝土(tu)綜(zong)(zong)(zong)合(he)管廊(lang)(lang)的主體結構(gou)施(shi)(shi)工(gong)(gong)(gong)(gong)大部分(fen)(fen)在場(chang)外完成(cheng)，管節的吊(diao)裝、拼裝等工(gong)(gong)(gong)(gong)序施(shi)(shi)工(gong)(gong)(gong)(gong)效率高，所需工(gong)(gong)(gong)(gong)期(qi)較短。而現澆(jiao)混凝土(tu)整體式(shi)綜(zong)(zong)(zong)合(he)管廊(lang)(lang)的主體結構(gou)施(shi)(shi)工(gong)(gong)(gong)(gong)則全部在場(chang)內完成(cheng)，占用了大量現場(chang)工(gong)(gong)(gong)(gong)期(qi)，是(shi)總工(gong)(gong)(gong)(gong)期(qi)的重(zhong)要組成(cheng)部分(fen)(fen)。施(shi)(shi)工(gong)(gong)(gong)(gong)中(zhong)(zhong)一(yi)個標準段對比(bi)，預制裝配(pei)式(shi)混凝土(tu)綜(zong)(zong)(zong)合(he)管廊(lang)(lang)的施(shi)(shi)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)期(qi)比(bi)現澆(jiao)混凝土(tu)整體式(shi)綜(zong)(zong)(zong)合(he)管廊(lang)(lang)縮(suo)短18d左(zuo)右，縮(suo)短近45%工(gong)(gong)(gong)(gong)期(qi)。
