7、橋,孔徑3-16m,交角105°,橋長84。86m,上部結(jié)構(gòu)采用裝配式先張預(yù)應(yīng)力混凝土空心板;下部結(jié)構(gòu)采用柱式墩、肋板式、樁基礎(chǔ)。二、施工工藝:施工前準(zhǔn)備:對臺背回填進(jìn)行強(qiáng)夯處理后整平,開挖基坑至設(shè)計(jì)標(biāo)高,坑底標(biāo)高和橫坡坡度根據(jù)線路標(biāo)高確定。搭板縱坡應(yīng)與路基坡度保持一致,基底進(jìn)行平整,夯實(shí)至設(shè)計(jì)要求。搭板墊層:立側(cè)模時(shí)務(wù)必保證模板的穩(wěn)定性,砼澆筑前,嚴(yán)格控制每輛車砼的塌落度,對不合格的堅(jiān)決退回。采用吊車配合灰車進(jìn)行澆筑。首先由人工將砼攤平,攤鋪厚度一般高出設(shè)計(jì)厚度1cm。采用插入式振搗棒振搗。插入
8、時(shí)宜快進(jìn)慢出,表面泛漿,不再冒氣泡時(shí)才能徐徐拔出振搗棒。振搗完成后,用木抹子進(jìn)行抹平,并進(jìn)行頂面高程的檢測,符合要求后將表面抹平。搭板鋼筋在加工場地集中加工,加工前應(yīng)對鋼筋進(jìn)行檢驗(yàn),合格后才能使用。嚴(yán)格按設(shè)計(jì)圖紙對鋼筋放樣加工,加工成型備用。鋼筋綁扎應(yīng)按圖紙要求進(jìn)行綁扎。鋼筋長度、間距等應(yīng)滿足設(shè)計(jì)和規(guī)范要求,并保證縱、橫向鋼筋直順。搭板鋼筋共兩層,下層縱向鋼筋為Φ22,上層縱向鋼筋為Φ16,為保證上下層鋼筋的間距和兩層間的整體強(qiáng)度,預(yù)先焊接梯形支架。綁扎上層鋼筋前將梯形支架安裝好,
