| 中文摘要:介绍了一种适用于微型工作井并采用拉顶式工艺施工的新型矩形掘进机的设计思路和设计方法及其主要的技术参数。新型矩形掘进机与掘进系统的拉进动力配合，解决了常规矩形顶管施工中的机头在轴线方向的倾偏及后退问题；机头采用多刀盘设计，各刀盘可以实现正反转，且转速可任意调节，有效降低了机头的偏转；而采用了辅助的纠偏装置，使新型掘进机在只有顶进动力的情况下也能实现正常的顶进施工。对在复杂环境条件下，改造、提升原有的掘进机性能具有重要的参考意义。 |

| Abstract:A new rectangular driving machine is introduced about its design method and its main technical parameters, which is suitable for micro working well with jacking-pulling construction technology. Combining the pulling force of driving system with the driving machine, deflection and backward of the machine head are solved in common rectangular pipe jacking construction. The machine head is designed with multi-cutter, each cutter is positive inversion and rotary speed can be easily adjusted with less machine head deflecting. The new driving machine can also be operated only with jacking force. |
