| 摘要: |
| 水平导向钻是当前进行非开挖市政建设施工的主流设备，为确保其施工安全，通常采用工作于地面的地下管线探测设备来掌握施工路线附近现有管线的分布状况。但由于探测原理的限制，一直存在探测盲区。本文提出一种新的解决方案，通过引进超声探测技术，将探测系统小型化并置于钻头上，形成随钻地下管线探测预警系统，实现随钻随测，当施工路线附近存在障碍管线时，向钻机操作人员实时告警。试验证明，本文提出的方案是可行有效的。 |

| Abstract: |
| Currently, horizontal direction drilling (HDD) has been considered as the mainstream in the trenchless technology used for municipal construction, in which the geo-radar and electromagnetic-based underground pipe detectors are widely used to find the distribution of pipes near the construction route so as to avoid destroying the latent buried pipes. Limited by detection principles, many objects cannot be detected effectively. In this paper, a novel solution for detecting underground pipes is proposed. By introducing tiny ultrasonic detecting system installed on the head of HDD, an online surveillance system for underground pipes was implemented with drilling and detecting implemented simultaneously. As a result, the system gave warning to the operators of the drilling when it detected pipes under the construction route. The experimental results show that construction risks of HDD were reduced considerately and the system proved to be effective. |
