沖樁班技術(shù)交底內(nèi)容:
    1.樁架上的機(jī)長(zhǎng)和成員應(yīng)持證上崗。
    2.樁架人員每天交班都要交底，將上一個(gè)臺(tái)班沖孔記錄交代清楚。
    3.在成孔過程中，如發(fā)現(xiàn)偏孔應(yīng)及時(shí)采取糾偏措施。當(dāng)進(jìn)巖時(shí)，應(yīng)做好取樣、分類、記錄等工作。
    4.鋼筋籠入槽前，必須對(duì)槽底泥漿和沉淀物進(jìn)行置換和清除。置換量不小于該槽段總體積的1/3置換和清除必須采用底部抽吸，頂部補(bǔ)漿方法。使底部泥漿比不大于1.3。沉淀淤積物(沉渣）厚度不得超過規(guī)范要求。
    5.鋼筋籠的構(gòu)造應(yīng)有利于入槽后的準(zhǔn)確就位和固定。吊運(yùn)過程中、不應(yīng)產(chǎn)生不可恢復(fù)的變形，不得強(qiáng)行入槽。鋼筋籠應(yīng)在泥漿置換合格后及時(shí)入槽后至澆筑砼時(shí)的總停置時(shí)間不宜超過6小時(shí)。澆筑砼時(shí)應(yīng)防止鋼筋籠上浮。
    6.砼應(yīng)采用導(dǎo)管法澆筑，導(dǎo)管按需要長(zhǎng)度拼接。導(dǎo)管距槽段端部不宜大于2m；砼的澆筑速度不宜小于每小時(shí)上升3~4m，導(dǎo)管插入砼內(nèi)的深度宜為2~4m，鑿去浮漿層后的墻頂標(biāo)高應(yīng)符合設(shè)計(jì)要求。
    7.槽段接縫處已澆筑的砼表面，必須用專門工具在鋼筋籠入槽前進(jìn)行清刷，分段縫施工時(shí)不得破壞已澆筑的相鄰段的砼。
Stone Pile class technical disclosure content:
    1. Browse the captain and the members of the pile should certificates.
    2. Pile frame shift each day and have correspondent, will be on a station class punching record clearly.
    3. In the hole process, if found to be partial hole to take timely corrective measures. When into the rock, they should do a good job sampling, classifying, recording and so on.
    4. Reinforcement cage into the tank prior to the mud and sediment on the bottom for replacement and cleaning. Replacement is not less than the slot, and the total volume of 1 / 3 of replacement and removal must be the bottom of the pump, fill the top of slurry method. To the bottom of the slurry is not greater than 1.3 than. Precipitation sludge (sediment) may not exceed the thickness specifications.
    5. Reinforcement cage of the structure should be conducive to the exact place into the trough and fixed. Lifting process, should not result in irreversible deformation, not forced into the slot. Reinforcement cage shall be replaced in the mud into the tank after passing the post in time to pouring concrete when the total holding time should not exceed 6 hours. Pouring concrete should be reinforced to prevent the floating cage.
    6. Concrete should be poured catheter, catheter length required stitching. Catheter tip from the slot section of not greater than 2m; the pouring of concrete should not be less than the hourly rate increased 3 ~ 4m, depth of catheter insertion within the concrete might be desirable for 2 ~ 4m, drilled to the top of the wall after the floating pulp layer should conform to the design elevation requirements.
    7. Groove section joints have been pouring concrete surface, special tools must be used in the reinforcement cage into the groove before clearing brush, construction joints shall not be damaged section had been pouring the adjacent section of the concrete.
