打桩工艺
pile driving process
螺旋打桩机就位→埋设护筒→钻头轻着地后开钻→放下钻头→钻孔完成,清孔并测定深度→放入钢筋笼和导管→进行混凝土灌注→护筒并整理桩头沉淤回填,，成桩。
the screw piling machine is placed in position, embedded in the retaining tube, after the bit is light to the ground, the drill bit and the drill is completed, the hole is cleared and the depth is measured, and the reinforcement cage and catheter are put into the concrete filling, and the retaining wall is filled and the backfilling of the pile head is finished, and the pile is made.
桩位放样
pile layout
在进行场所整平后, 安排有资历的丈量放样人员将所有桩位放出, 钉好十字维护桩, 做好丈量复核, 并记载放样数据存案。
after the leveling of the site, all the posts with seniority are arranged to release all the pile positions, nail the cross maintenance piles well, check the measurement, and record the sample data.
埋设护筒
burial tube
用拉线法查看桩位误差, 应标准要求。
the drawing line method is used to check the error of pile position, and it should be standard.
成孔
pore forming
采用钻头钻进, 根据不同层次的土质结构挑选不同的转盘转速和进尺进行操控。在砂层钻进和强风化层后, 因土层太硬会引起钻锥跳动及偏斜、加大钻杆, 故应挑选低档慢速, 转盘转速参数取值 13~40v/ min, 成孔深度按规划要求进行操控。
using bit drilling, different turntable speed and footage are selected according to different levels of soil texture. after the sand layer is drilling and strong weathering layer, because the soil layer is too hard, the drill cone will jump and skew and increase the drill rod. so the low speed and slow speed should be selected and the rotating speed parameter of the turntable is 13~40v/ min. the hole depth is controlled according to the planning requirements.
钢筋笼制安
steel cage system
螺旋打桩机挖土清渣到达规划要求后,，开端下放钢筋笼, 其制安有必要严厉依照规划图纸进行,，主筋、箍筋应焊接均匀,，搭接长度及焊缝应契合标准要求， 装置时应装置护块,，以保证周正及维护层厚度,，钢筋笼的制作误差应契合规划及标准要求。
after the spiral piling machine excavating the slag to reach the planning requirements, the steel cage should be put down in the beginning. it should be carried out strictly according to the planning drawings, the main tendons and the stirrup should be welded evenly, the length of the lap and the weld should meet the standard requirements, the device should be equipped with the protective block to ensure the thickness of the circle and the maintenance layer, and the production error of the steel cage should be made. meet the requirements of the planning and standard.
混凝土灌溉
concrete irrigation
在导管接驳结束后, 将混凝土隔水栓吊临近泥浆面的方位,，导管底端到孔底间隔操控在0.4m左右，以便能顺利混凝土隔水栓。开端灌注前储料斗内储藏的混凝土量应不少于 1.0m3， 以便在混凝土隔水栓被挤出导管后能将导管底端一次性埋入水下混凝土中 0.8m 以上, 适时或拆卸导管, 保证导管底端埋入混凝土面以下 1~4m, 灌注应接连进行。一旦发活力具毛病或停电停水及导管阻塞或进水等事端时, 应采纳有用办法进行处理, 以便赶快康复灌注混凝土, 一起做好记载。
after the end of the pipe connection, the concrete water plugs hang near the azimuth of the mud surface, and the bottom of the pipe is controlled at about 0.4m at the bottom of the hole, so that the concrete water plugs can be smooth. the amount of concrete stored in the storage hopper before the beginning of the filling should not be less than 1.0m3, so that the bottom end of the pipe can be embedded more than 0.8m in the underwater concrete at the bottom of the pipe after the concrete water plug is extruded, and the catheter is dismantled in time or dismantled to ensure that the bottom of the conduit is buried under the concrete surface 1~4m, and the irrigation should be carried out. a useful method should be adopted in order to quickly rehabilitate the concrete and make a good record of the concrete.
