【正文】 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(yīng)事先套在波紋管頭部一同套入）。鋼鉸線穿好后，要仔細檢查波紋管，如發(fā)現(xiàn)有裂口或小洞，先用海綿堵住，再用膠帶纏牢。（七）混凝土澆注為保證工程質(zhì)量，箱梁采取兩次澆注，即先澆筑底板，再澆注腹板和頂板，施工縫留在底板與腹板交接處。采用泵送砼，由4墩向0臺方向澆注。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。準備工作主要從以下幾個方面進行檢查：原材料：用于本工程的原材料必須按技術(shù)規(guī)范的要求進行抽查，不合格的材料不能進場。原材料的數(shù)量要滿足混凝土的要求，不能出現(xiàn)缺料現(xiàn)象。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。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。此外還應(yīng)對備用機械、振搗設(shè)備等進行全面的檢查，確保滿足需要。對支架進行檢查：檢查支架下墊板是否與地面充分接觸，上、下托是否與墊板龍骨頂緊，發(fā)現(xiàn)問題及時處理，檢查各桿件是否橫平豎直，間距是否符合要求。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。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。預(yù)埋件再進行一次全面檢查，有無錯位、漏埋現(xiàn)象?；炷翝沧⑹┕ろ樞颍焊鶕?jù)砼初凝時間將箱梁分若干單元澆筑，從4墩向0臺逐次推進，每單元澆筑采用先底板后腹板的澆筑順序。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。待腹板面板混凝土施工，內(nèi)模拆除后，將面板的鋼筋接齊，用摻入鋁粉的微膨脹C50混凝土澆注補齊，并加強養(yǎng)護。Opinions and suggestions on the party39。s mass line educational practiceAccording to the central and provincial, municipal unified deployment, according to municipal Party mittee about carrying out the party39。s mass line educational practice activity in the city39。s implementation opinions, the spirit of the party39。s mass line educational practice activities from 20** in January to 99 months, carried out at all levels of departments and directly affiliated institutions and grassroots party organizations.
