29、稳用溜绳控制，吊索保持垂直，操作平稳，尽量避免紧急制动，以便就位。d.校正：根据设计要求和规范规定，对梁平面位置、标高、垂直度等进行校正。(4)安全生产施工：a.吊装前对设备、工具等 进行安全性能检查；b.吊装人员进入现场必须戴安全帽，高空作业系统安全带。c.吊装时，禁止人员站在梁上指挥，起重臂下严禁站人。d.起重臂、吊索、吊绳与电源线要保持一定的安全距离。e.设置专人负责指挥，严禁乱指挥。5.桥面铺装：(1)伸缩缝：清理伸缩缝缝槽，如有顶头现象或缝宽不符合设计要求时，应凿剔平整，在桥面砼干燥收缩完成且徐变在部分完成后再进行安装，安装后的桥面伸缩缝的伸缩性能必须有效，缝面与桥面结合良好，并保持
30、平整。(2)桥面铺装a.清基：在桥面铺装前先清扫桥面，然后用水冲洗干净。b.槽缝灌浆：拌制水泥砂浆或细石砼灌注槽缝。c.立模：采用制作的定型钢模板进行模板的安装，模板要牢固、紧密，在整个长度上与基层紧贴，不漏浆。d.焊接、扎筋：按照设计要求焊接横向联结钢板，铺设纵向接缝钢网或桥面钢筋网。e.浇筑砼：1.0m3强制式搅拌机拌和；6m3搅拌车运输；25t塔式起重机配3.0m3吊罐吊运入仓；机械摊铺；振捣以砼停止下沉，不再冒气泡并泛出砂浆为准，表面整平时，铺设一层细石砼；待表面抹平砼初泞后，按照设计要求的表面构造深度沿横坡方向拉毛；根据图纸要求埋设泄水管。7.6.2.3钻孔灌注桩先基坑支护桩，后桥台
31、桩。由闸轴线向上、下游施工。1.根据地质剖面图知钻孔灌注桩范围内为粉质粘土、淤泥质粘土和淤层，拟选用CZ-22型冲击钻机，为防止振动使邻孔壁坍塌以及影响邻孔已浇筑砼凝固，采用隔孔跳打法进行施工。工艺流程如下图：平整场地构筑钻机平台桩位放样埋设护筒安设钻架制作护筒钻机就位钻 进固壁浆液循环系统下钢筋笼测量孔深孔径孔斜清 孔安设清孔设施测量淤泥土厚度制作吊运钢筋笼安设导管溜槽等浇筑砼制备、运输砼试装检验导管养 护拔除护筒测量砼高度护筒：使用5mm钢板制作护筒，护筒内径比钻头直径大20cm，根据灌注桩位置地形条件和地下水位情况，采用挖埋法安设护筒，护筒高出施工地面30mm,在护筒底及周围回填粘土、夯
32、填密实防止漏水，护筒中心与桩位中心的偏差不大于5cm，倾斜度偏差不大于1。钻孔：钻孔开始后分班连续作业，一次成孔。在钻孔过程中由专人进行钻孔记录，注意土层变化，采取渣样，判断土层；选用优质粘土，掺入膨润土粉，提高泥浆的粘度和胶体率，护筒内泥浆顶面保持高出筒外水位1.5m；做好泥浆回收净化，循环使用工作。清孔：采用掏渣清除法，保持孔泥浆的浆面高程，以保证孔壁的稳定。吊放钢筋：按设计图纸加工制作钢筋，利用钻机起重机起吊钢笼入孔，钢笼周围绑扎砼垫以保证保护层；准确牢固定位钢笼，防止浇筑过程中错位和浮笼。灌筑水下砼：砼的浇筑采用直开导管法，浇筑要连续作业；浇筑砼用专用浇筑(如下图)；浇筑到桩顶时，要高
