35、越障碍物的敷设段。导向孔轨迹的形态取决于穿越起点(A点)、穿越终点 (B点)、敷管深度 (h)、造斜段曲率半径 (R1、R2)等参数,其中R1 由钻杆最小曲率半径 (Rd)和敷管深度 (h)决定,根据经验Rd1 000d(d为钻杆直径 ,50 mm);R2由所敷管的弯曲半径决定。工程中一次牵引敷设管线最大长度为按实际地形而定，但不得超过设计规范要求 ,当敷设长度过大或受场地等外界因素影响时牵引机械不足以一次完成拖管工作,这时需要采取分段牵引施工(见图2)。AB段的导向孔打通以后先用200 的回扩头回扩一次,然后把回扩头推至AB段中点O;在O点挖坑 (2 m 4 m 6 m),换上钻头沿曲线钻进

36、至M点出土,顺次回扩拖管 ,完成AO段管道的敷设;后退23 m 以点N作为入土点沿曲线钻进至O点(确保达到预定深度),然后换上回扩头顺着原孔推至P点出土 ,顺次回扩拖管,完成OB段管道的敷设。文档编码:CV10A7J4P5R1 HP9W7Y9D8X4 ZR1C3H1C8Q6文档编码:CV10A7J4P5R1 HP9W7Y9D8X4 ZR1C3H1C8Q6文档编码:CV10A7J4P5R1 HP9W7Y9D8X4 ZR1C3H1C8Q6文档编码:CV10A7J4P5R1 HP9W7Y9D8X4 ZR1C3H1C8Q6文档编码:CV10A7J4P5R1 HP9W7Y9D8X4 ZR1C3H1C8Q
