測設(shè)粉噴樁樁位，樁位誤差≤3cm，經(jīng)復(fù)核確認后，用白灰（或插明顯標(biāo)簽）準(zhǔn)確放出樁位點。2 樁機就位 粉噴樁樁機就位，鉆頭對位后調(diào)平樁機機臺，精確對位，偏差≤5cm,垂直度偏差≤%。3 水泥選擇 水泥必須有質(zhì)量合格證，并經(jīng)工地取樣復(fù)檢合格，不得使用受潮、結(jié)塊、變質(zhì)的水泥。3 鉆進開鉆前檢查鉆頭，如發(fā)現(xiàn)其直徑磨耗超過 1cm 時，應(yīng)及時修補或更換。鉆進時啟動電機下鉆，待鉆頭接近地面時，啟動自動記錄儀，空壓機送氣，并鉆進。4 噴粉鉆到設(shè)計深度時，停止鉆進，打開送料閥門，關(guān)閉送氣閥門，噴送加固料，再邊送料邊攪拌邊提升鉆頭，在噴灰攪拌過程中，送灰要連續(xù)足量，不得中斷。噴粉作業(yè)人員應(yīng)戴口罩和防護鏡。當(dāng)噴嘴接近地面時，應(yīng)防止噴粉傷人。噴灰必須均勻、攪拌充分，噴灰量不小于設(shè)計值。施工時應(yīng)做好記錄工作，簽認齊全，施工原始記錄不得弄虛作假和涂改。5 復(fù)攪 攪拌鉆頭再鉆至設(shè)計復(fù)攪深度，并反鉆提升進行復(fù)攪。6 成樁 樁長≥設(shè)計值，成樁直徑≥設(shè)計值。接受人： 交底人： 大西鐵路客專站前一標(biāo)漿體噴射攪拌樁施工工序作業(yè)要點卡片序號 工序 作業(yè)控制要點1 測量放樣 測設(shè)漿噴樁樁位，樁位誤差≤3cm，經(jīng)復(fù)核確認后，用白灰（或插明顯標(biāo)簽）準(zhǔn)確放出樁位點。2 樁機就位 鉆機就位，對正樁位，保證鉆桿垂直。樁位偏差≤5cm,垂直度偏差≤%。3 水泥選擇 水泥必須有質(zhì)量合格證，并經(jīng)工地取樣復(fù)檢合格，不得使用受潮、結(jié)塊、變質(zhì)的水泥。3
