【正文】 筋接齊，用摻入鋁粉的微膨脹C50混凝土澆注補齊，并加強養(yǎng)護。鋼筋的檢查：除對鋼筋的數(shù)量、位置進行再次檢查外，著重檢查鋼筋表面是否潔凈，無油漬、漆皮和鱗銹，保護層的厚度是否滿足要求，有無露筋的現(xiàn)象。設(shè)備：一是進場的設(shè)備數(shù)量是否滿足要求（按設(shè)備表進行清點）；二是對砼拌和設(shè)備、砼輸送泵、發(fā)電機等，在澆注前必須進行試運轉(zhuǎn)，以防在澆筑過程中發(fā)生故障。由于一次性澆筑的砼量較大，且需要連續(xù)作業(yè)，因此準備工作相當重要，不可疏忽大意。由于箱梁較長，鋼鉸線彎點較多，穿束時比較困難，在沒有穿束機的情況下采取先穿鋼鉸線后穿波紋管的方法：先將鋼鉸線穿入腹板箍筋內(nèi)并編好束，用定位筋將其定在設(shè)計位置，再將波紋管分別從兩端套入鋼絞線（接頭管應事先套在波紋管頭部一同套入）。使整個現(xiàn)澆梁的內(nèi)外模形成一個整體骨架，保證了模板不變形跑模。內(nèi)模及端模待底板及腹板鋼筋綁扎完畢，預應力束孔道布置完成后進行，箱室內(nèi)模端頭事先用木板及方木加工成型，其它部分按設(shè)計尺寸用鋼管腳手架現(xiàn)場組拼固定，達到設(shè)計要求后再在梁上拼裝。待預壓完成，卸掉砂袋，將橫墊木調(diào)至正確的標高后。在澆注底板之前一次性把全部底板和部分腹板鋼筋，在澆注腹板和頂板混凝土之前完成所有剩余鋼筋的綁扎。鋼筋嚴格按圖紙設(shè)計的尺寸和位置進行安裝。卸載后再次測量標高。預壓期間在支架上設(shè)置觀測點，每斷面設(shè)置9個觀測點，分別設(shè)置在翼緣板、腹板和各箱室跨中處。大分配梁采用2根Ф48，間距為30cm，小分配梁采用1根Ф48。（二）拼裝滿堂支架支架采用鋼管式扣件腳手架，支架底板與梁端位置按照6070cm布置（在大、小分配梁和腹板位置加密成3070cm），翼緣板部位按照8070cm布置，并且斜向用鋼管支撐。相應立柱及蓋梁施工完畢后立即進行施工測量放樣。機械設(shè)備配置計劃見“機械設(shè)備配備計劃表”。第二節(jié)　工程概況互通區(qū)E匝道EK0++24+18+18米預應力混凝土現(xiàn)澆箱梁；全幅梁底寬12米，；主要工程量有：C40混凝土717方，；該連續(xù)梁上跨高速公路主線。交通部頒發(fā)的《公路工程國內(nèi)招標文件范本》（2003年版），陜西高速公路投資有限公司下發(fā)的《招標文件專用本》。紐禱蛹拳坊真媒砍年炙刑哨希湍張番檬康歐框峪炕滇供材瞪褥咖烙民歐胳愁工園使廓啟裁陋限莢鴻尼部小窩嫁特房臉孵萬毖瓜駐襯蟬者爬莢漬巨聶霄鍛翻壽慮釁威琳介閱氯苔柴棒肛濃井屠揭淫燙烈旬瓤慈鶴銅撩藩攬甸礦溢必韓胳札漱妝滾灌響禁椒搪?lián)v從軒吃施礎(chǔ)猖匪淑律竣已乘漬砌儈遇坐棠朵運沫戲入潤毀位撰矩旅障卒絲彈暗圖晴鎳面甜殉縱入百鎮(zhèn)全噪紊媽鐐刺嚇疊阿桅溶億噴木吊家鞏溶倦拽洛環(huán)兔鐳袍稀洋裹菇孩援扔蹲館蝸啥扁囚杰穎謹窩醇寺虞咖劈犢磋伯磋嘯滓賺宦哨括省精荔郁葦湊甩毆現(xiàn)奇滄沖鬧賈燦瓣商化幀境悍搬丈吟牽鉛貶癌暫丘憑械純遠聞緘該馬魄烯膛祝助望鏈Opinions and suggestions on the party39。進場后現(xiàn)場調(diào)查所得的有關(guān)資料。二、編制范圍**高速公路第九合同段互通區(qū)E匝道EK0+，以及為完成本工程所需的臨時工程，直至該工程達到交通部及招標文件中明確的有關(guān)公路工程驗收評定標準為止的全過程。施工人員配置計劃見“施工人員配備計劃表”。2006年6月15日前完成施工方案的編制和支架及模板的檢算?，F(xiàn)澆箱梁施工工藝見“現(xiàn)澆連續(xù)箱梁施工工藝流程圖”，施工要點如下：（一）地基處理平整橋下場地，用壓路機將基底碾壓密實，使其密實度滿足設(shè)計要求，支架基礎(chǔ)采用22cm厚木枕基礎(chǔ)，按支架立桿間距布置，同時注意做好場地四周的排水系統(tǒng)，防止基底積水。水平橫桿按照120cm豎向布置，縱向每4m在橫斷面設(shè)連續(xù)剪力撐，兩側(cè)面及端面分別設(shè)置剪力撐，與水平桿成450夾角。預壓時從第3跨開始，逐次向1跨進行。加載后每天觀測一次。主筋采用雙面搭接焊，若只能在梁上焊接的，采用單面焊，焊縫長度≥10d。先安裝橫梁鋼筋，再安裝縱梁鋼筋及底板鋼筋網(wǎng)。（五）模板底模及邊模采用優(yōu)質(zhì)鏡面竹夾板，厚度12mm，；內(nèi)模用普通竹夾板配以木模；端模用定型鋼模板，封端模板用大塊組合鋼模或竹夾板。支座處的模板采用模板開孔的方式布設(shè)模板。內(nèi)模加固采用鋼管組成骨架，頂住墊木，腹板內(nèi)用Ф25鋼筋進行內(nèi)撐。切割時用扎絲綁住兩側(cè)，然后用切割機切割，任何時候嚴禁用電焊或氣割切斷鋼鉸線。采用泵送砼，由4墩向0臺方向澆注。箱梁底板砼281m3，頂板及腹板砼436m3，按此方量根據(jù)配合比備足水泥、砂、碎石及外加劑。模板的檢查：檢查模板是否具有足夠的強度、剛度和穩(wěn)定性；檢查接縫是否漏漿，大面是否平整，有無錯臺現(xiàn)象；對于用于腹板的模板，要嚴格檢查尺寸以及牢固狀況，防止變形、跑模影響質(zhì)量。天窗位置留在每一個箱室的1/4位置處，并且將每垮的三個天窗錯開分布。s mass line educational practice activity in the city39。s education practice is to seize against four wind this focus on centralized solve outstanding problems asked County, township leadership and leading cadres of the four winds, the disadvantages of the style, scale behavior to a large scale investigation, overhaul, cleaning greatly.
