32、.4防水施工防水是洞門(mén)工程施工的一個(gè)很重要的環(huán)節(jié)，它的質(zhì)量是通過(guò)第一道到最后一道工序內(nèi)各防水環(huán)節(jié)的質(zhì)量來(lái)綜合體現(xiàn)，任何一個(gè)環(huán)節(jié)做得不好，都有可能對(duì)整體防水效果產(chǎn)生很大的影響，因此在整個(gè)施工過(guò)程中，必須加強(qiáng)過(guò)程控制，一步一步地做好每一道工序的防水質(zhì)量。隧道洞門(mén)和盾構(gòu)隧道、盾構(gòu)工作井端墻的連接部位，拐角多，施工縫多，是防水工作的難點(diǎn)。洞門(mén)采用C40、P10補(bǔ)償收縮混凝土進(jìn)行施工，在洞門(mén)砼灌注前，認(rèn)真清理洞門(mén)預(yù)埋鋼環(huán)內(nèi)側(cè)污物，涂刷氯丁膠，粘貼兩道遇水膨脹橡膠帶，并涂刷緩膨劑，接下來(lái)預(yù)埋注漿管，然后灌注洞門(mén)抗裂防滲鋼筋砼，待砼凝固后及時(shí)通過(guò)注漿管壓注水泥漿，保證洞門(mén)背后密實(shí)。防水施工主要包括緩膨型遇水

33、膨脹橡膠止水條的粘貼以及洞門(mén)環(huán)梁澆注后進(jìn)行注漿堵水。緩膨型遇水膨脹橡膠止水條的粘貼在粘貼緩膨型遇水膨脹橡膠止水條的部位用高壓水槍清洗干凈，待表面干燥后，在均勻涂刷單組氯丁酚醛粘結(jié)劑。粘結(jié)劑涂刷后，涼置一段時(shí)間（1015min），待手指接觸不粘時(shí)，再將橡膠條粘結(jié)壓實(shí)。沿緩膨型遇水膨脹橡膠止水條長(zhǎng)度方向每隔500mm用高強(qiáng)釘加以固定。緩膨型遇水膨脹橡膠止水條延伸使用時(shí)，接頭處采用重疊的方法進(jìn)行搭接，搭接長(zhǎng)度100mm，并用高強(qiáng)釘加以固定，安裝路徑應(yīng)閉合成環(huán)，其間不得留斷點(diǎn)。緩膨型遇水膨脹橡膠止水條應(yīng)平順，不得出現(xiàn)脫膠、起鼓、歪曲等現(xiàn)象。澆注混凝土振搗時(shí)，應(yīng)避免振搗棒觸及緩膨型遇水膨脹橡膠止水條。5

34、.5綁扎鋼筋鋼筋在加工車間進(jìn)行加工，要保證主筋圓弧準(zhǔn)確、圓順；運(yùn)至工作面進(jìn)行綁扎、焊接，利用預(yù)埋鋼環(huán)或植筋作為固定鋼筋；靠近模板的鋼筋要綁上預(yù)制混凝土墊塊，以保證混凝土保護(hù)層厚度，避免露筋現(xiàn)象。5.6立模模板采用特殊加工的鋼模板（定制），確保洞口的尺寸精度，保證砼表面光潔、美觀。模板拼裝嚴(yán)密，不漏漿，使用前應(yīng)試拼一圈檢查。在模板與管片相接處的模板上貼一圈膨脹止水條防止兩者相接處漏漿。端頭模板采用弧形鋼堵頭。堵頭模板采用預(yù)埋螺桿固定，洞門(mén)模板在拱頂及拱腰設(shè)特殊堵頭板，方便砼的振搗。堵頭板與鋼模相接處及鋼模與管片相接處采用粘結(jié)膨脹止水條的方法防止漏漿。模板、鋼筋、防水層等經(jīng)檢查驗(yàn)收達(dá)到設(shè)計(jì)、規(guī)范要
