41、抗拉强度试验。为保证主筋间距和钢筋笼的整体刚度，固定架立筋应与主筋焊牢，箍筋与主筋绑牢，成形后的钢筋笼外形尺寸、主筋位置、数量等应与设计相符合。1.3钻孔： 钻机就位时,经专人检查桩位的偏差及垂直偏差，符合要求后方可开钻,终孔后经专人检查孔深符合要求后退出钻机。1.4验笼顶标高： 砼浇灌前, 应有专人检查钢筋笼的笼顶标高, 符合要求后方可进行浇灌。1.5浇灌砼： 单桩砼的浇灌要连续, 若遇两次浇灌，时间间隔要小于1小时, 以免形成断桩。1.6砼强度：按照规范要求及时留置试块（100100100mm），进行标养。2、护坡桩工艺流程: 平整场地复测孔位安装桩机调平钻机底座并对正桩位钻进到位后清孔检
