綜(zong)合管廊早拆(chai)滑(hua)架(jia)方案(an)的由來(lai)
綜(zong)合(he)管廊施(shi)(shi)工大體(ti)(ti)可(ke)分為(wei)三類：傳統（散拼散拆）方(fang)案(an)、整體(ti)(ti)臺車(che)方(fang)案(an)、早拆方(fang)案(an)。在管廊大斷面結(jie)構尺(chi)寸施(shi)(shi)工中，由(you)于頂(ding)(ding)板混凝土強度(du)需達到設(she)計拆模強度(du)方(fang)可(ke)拆模，需占用頂(ding)(ding)板支撐(cheng)架體(ti)(ti)較長(chang)時(shi)間，所以限制了(le)散拼散拆方(fang)案(an)和整體(ti)(ti)臺車(che)方(fang)案(an)支撐(cheng)架體(ti)(ti)的材(cai)料(liao)周轉(zhuan)率。為(wei)了(le)解決施(shi)(shi)工材(cai)料(liao)周轉(zhuan)率低的問題，早拆方(fang)案(an)應市場需求出(chu)現(xian)，其原理是通(tong)過在頂(ding)(ding)板預留晚拆帶以減小結(jie)構跨度(du)的方(fang)式提高(gao)支撐(cheng)架體(ti)(ti)材(cai)料(liao)的周轉(zhuan)率。傳統早拆(chai)(chai)方案(an)(an)施(shi)(shi)(shi)工(gong)(gong)雖然提高了(le)管廊支撐(cheng)(cheng)架體材(cai)料的周轉(zhuan)(zhuan)率(lv)，但對模(mo)板(ban)(ban)及支撐(cheng)(cheng)加(jia)固材(cai)料還是以散(san)支散(san)拆(chai)(chai)進行施(shi)(shi)(shi)工(gong)(gong)，其(qi)工(gong)(gong)效并沒有明顯提高。為提高項目施(shi)(shi)(shi)工(gong)(gong)效率(lv)，減少材(cai)料及人工(gong)(gong)費用投入，縮短項目施(shi)(shi)(shi)工(gong)(gong)工(gong)(gong)期，易(yi)安特推(tui)出早拆(chai)(chai)滑架方案(an)(an)，此方案(an)(an)結合(he)了(le)傳統早拆(chai)(chai)方案(an)(an)、整體臺(tai)車方案(an)(an)兩者的優(you)點(dian)，并配合(he)應用易(yi)安特復合(he)材(cai)料模(mo)板(ban)(ban)，方案(an)(an)在保留頂(ding)板(ban)(ban)晚拆(chai)(chai)帶的形式上，將頂(ding)板(ban)(ban)模(mo)板(ban)(ban)及支撐(cheng)(cheng)加(jia)固件同側(ce)墻模(mo)板(ban)(ban)加(jia)固材(cai)料整體周轉(zhuan)(zhuan)。以3*3.7m凈寬為例，周轉(zhuan)(zhuan)單元長(chang)度3.6m，重量(liang)僅1.2噸，材(cai)料周轉(zhuan)(zhuan)率(lv)及施(shi)(shi)(shi)工(gong)(gong)工(gong)(gong)效都得到了(le)顯著的提升(sheng)。
