沉入樁基礎(chǔ)
鋼筋混凝土樁采用錘擊沉樁時，施工場地應(yīng)保護平整清潔，打樁機的移動軌道，鋪設(shè)要平順、軌距要準(zhǔn)確、鋼軌要釘牢，軌道端部應(yīng)設(shè)止輪器。打樁架移動時，應(yīng)在現(xiàn)場施工負(fù)責(zé)人指揮下進行。樁架移動應(yīng)平穩(wěn)，樁錘必須放在最低位置，柴油打樁機后部的配重鐵必須齊全。采用滾杠滑移打樁架作業(yè)時，作業(yè)人中不得在打樁架內(nèi)操作。水上打樁平臺，必須搭設(shè)牢固，打樁機底座與平臺應(yīng)連接牢靠。浮式沉樁設(shè)備沉樁時，樁架與船體必須連接緊固。船體定位后，應(yīng)以錨纜封固，并防止施工中浮船晃動。起吊沉樁或樁錘時，嚴(yán)禁作業(yè)人員在吊鉤下或在樁架龍門口處停留或作業(yè)。打樁架及起重工具，應(yīng)經(jīng)常檢查維修，樁錘檢查維修，必須將樁錘放落在地面或平臺上，嚴(yán)禁在懸掛狀態(tài)下維修樁錘。采用高壓水泵等助沉措施，其高壓水泵的壓力表、安全閥、水泵、輸水管道及水壓等應(yīng)符合安全要求。高壓射水輔助沉樁，應(yīng)根據(jù)地質(zhì)情況采用相應(yīng)的壓力，并要防止因急劇下沉造成樁架傾倒。射水沉樁，應(yīng)在樁身入土達到穩(wěn)定時再射水。震動打樁機開動后，作業(yè)人員應(yīng)暫離心基樁。震打中如發(fā)現(xiàn)樁回跳動、打樁機有異聲及其它不正常的情況時，應(yīng)立即停震，并經(jīng)檢查處理后再繼續(xù)作業(yè)。所有開、停震必須聽從指揮。震動打樁機在停止作業(yè)后，應(yīng)立即切斷動力源。
墩臺工程  就地澆筑墩臺施工
 施工前必須搭好腳手架及作業(yè)平臺，并在平臺外側(cè)設(shè)欄桿。墩高在10m以上時，應(yīng)加設(shè)安全網(wǎng)。吊斗 升降應(yīng)設(shè)專人指揮。落斗前，下部的作業(yè)人員必須躲開，不得身倚欄桿推動吊斗。嚴(yán)禁吊

Sinking into the pile
Reinforced concrete piles sunk by hammer pile, the construction site should be protected flat clean, pile the mobile track, laying to ride, to accurately gauge, rail to clinch the track ends should be located just round device. Piling frame moves, the construction leader in the field should be carried out under the command. Post holder should be a smooth move, pile hammer must be placed in the lowest position, diesel pile driver to the rear complete with heavy rail. Piling frame with roll bars slip operation, the operation within the framework of those not in the piling operation. Water piling platform, to be strong erection, pile base and the platform should be connected securely. Floating pile driving equipment, pile driving, the pile fastening frame must be connected with the hull. Hull orientation, should be to anchor cable zonal isolation, and to prevent the construction of floating boat shaking. Lifting or pile hammer pile driving is strictly prohibited workers the hook or pile under the door frame long stay or work office. Piling frame and lifting gear, regular checks of maintenance, inspection, maintenance and pile hammer, pile hammer must fall on the ground or platform release is strictly prohibited in the state of maintenance of pile hammer hanging. Journal of high pressure pumps and other assistance measures, the high pressure pump pressure gauge, safety valves, pumps, water pipes and water pressure and so should be safe. High pressure water jetting auxiliary pile should be used according to the geological situation of the corresponding pressure and to prevent the dumping of rapid subsidence caused by pile frame. Water Jet pile should be buried in the pile to stabilize the water again when the shot. Vibration pile driver is activated, the operating personnel should be temporary centrifugal pile. Earthquake hit back to beat found piles, pile-drivers have different sound, and other irregularities should be stopped immediately shock, and then continue through check processing operations. All open, stop shock must obey orders. Vibration pile driver to stop work in, it should be immediately cut off the power source.
Construction works on the spot pouring pier pier
 Before construction and setting up the scaffolding and platforms, and the platform set up outside the railing. Pier height above 10m, should be added as a safety net. Skip command hand movements should be located. Off before the fight, the lower part of the work must escape, not skip body leaning against the railings to promote. Non-suspended
