29、督和現(xiàn)場安裝，供應(yīng)科負(fù)責(zé)相關(guān)機(jī)具、材料的租用和購買。施工負(fù)責(zé)人分別為：檢修段限高架制作負(fù)責(zé)人×××，分管領(lǐng)導(dǎo)×××。工務(wù)段施工負(fù)責(zé)人：×××；分管領(lǐng)導(dǎo)×××。主管科室管理人員：×××；負(fù)責(zé)領(lǐng)導(dǎo)×××。2 工程施工方案2.1 開工前交底及開工準(zhǔn)備會：運(yùn)輸科組織工程相關(guān)單位現(xiàn)場交底，確定限高架設(shè)置的詳細(xì)位置（明確到具體尺寸）、高度。同時舉行開工準(zhǔn)備會，統(tǒng)一協(xié)調(diào)限高架制作與施工過程中的責(zé)任分工及注意事項(xiàng)，明確施工各工序檢查

30、和驗(yàn)收的步驟，確定開工時間。2.2 鋼結(jié)構(gòu)制作：鋼結(jié)構(gòu)制作前，工務(wù)段試驗(yàn)5根鋼軌按圖紙的布置方法和跨度安裝后，其下垂量達(dá)到多少，以根據(jù)橋梁高度具體確定限高架橫梁高度。鋼軌下垂量確定后，檢修段挑選具備使用條件的鋼軌等各種材料，按照圖紙要求進(jìn)行鋼結(jié)構(gòu)的加工，共需制作6個限高架立柱。其中雪楓路立交橋4個，橫梁底部的高度為3.75米（與橋梁頂部高度保持一致）。車集地銷路立交橋須立柱2個，位于橋梁以北，橫梁底部的高度為4米（與橋梁頂部高度保持一致）。限高架立柱具體做法見圖紙。加工完畢后形成可直接吊裝的立柱，橫梁可在立柱施工完畢具備承重條件后吊裝并連接。加工完成后進(jìn)行除銹，除銹完畢后刷每段20cm長、黑白

31、相間的反光漆。2.3 現(xiàn)場施工：在鋼結(jié)構(gòu)制作即將完成的時候開始現(xiàn)場基坑的施工和基礎(chǔ)鋼筋的綁扎，基坑挖深2.1米，下部10cm厚C30混凝土為墊層，用于支承立柱和控制立柱施工高度，上部2米為C30鋼筋混凝土基礎(chǔ)，將加工好的立柱的下部2米埋于該基礎(chǔ)之中?；邮┕ね瓿珊罅⒓词┕せA(chǔ)底部10cm厚墊層，墊層厚度可適當(dāng)增加用于調(diào)整墊層頂部標(biāo)高，確保立柱標(biāo)高正確，同時準(zhǔn)備好混凝土澆注的各項(xiàng)準(zhǔn)備工作?；讐|層達(dá)到足夠強(qiáng)度后將制作好的立柱運(yùn)至現(xiàn)場吊裝，吊裝完畢后復(fù)測各項(xiàng)標(biāo)高是否合格，確保合格后對立柱進(jìn)行可靠的固定，并安裝鋼筋進(jìn)行混凝土的澆注。待基礎(chǔ)混凝土達(dá)到足夠強(qiáng)度后進(jìn)行橫梁的吊裝和固定。具體做法見圖紙。2.4 竣工驗(yàn)收：全部施工完成后，由工務(wù)段進(jìn)行初驗(yàn)，初驗(yàn)合格后由運(yùn)輸科組織處領(lǐng)導(dǎo)、主管科室、項(xiàng)目單位、安監(jiān)科、監(jiān)察科等參加的竣工驗(yàn)收。3 限高架施工圖紙限高架施工圖紙包含平面圖、立面圖、基礎(chǔ)圖，由于兩個立交橋限高架完
