Industry Challenge
传统探测方法难以解决“最后一公里”
Traditional detection struggles with the last mile
存量长输管道规模大，定向钻、顶管、盾构等穿越段埋深高、环境复杂，位置不清会直接放大施工、运营和第三方破坏风险。
Deep HDD, pipe-jacking and shield crossing sections are difficult to locate, increasing construction, operation and third-party damage risks.
01
位置资料不准
Uncertain Records
历史施工粗放、城市快速变迁，管道常出现“知其有，不知其精确位置”。
Historic records and changing terrain often fail to provide reliable coordinates.
02
交叉并行密集
Dense Corridors
公路、铁路、电网、通信与管线同廊带集中，施工风险持续上升。
Transport, power, telecom and pipeline corridors overlap, raising construction risk.
03
深埋复杂地形
Deep Complex Terrain
河流、山体、水域、构筑物和强电磁干扰使常规仪器精度不足。
Rivers, mountains, structures and interference limit conventional tools.
| 方法 | Method | 主要限制 | Limitation | 大埋深适用性 | For Deep Sections |
|---|---|---|---|---|---|
| 探管仪 | 埋深通常受限于 3-5 米，多管并行和高压干扰下失效 | Usually limited to 3-5 m and vulnerable to interference | 受限Limited | ||
| 探地雷达 | 构筑物、水域、并行管道和强电磁环境下误差大 | Large errors under structures, water, parallel lines and interference | 误差大High Error | ||
| 陀螺仪 | 需管道开口、停输并牵引，对在役油气管道不友好 | Requires opening, shutdown and traction for many applications | 需停输Shutdown | ||
| BPDS | 免开口、免打孔、非接触、抗干扰、可不停输探测 | No opening, no drilling, non-contact, anti-interference, no shutdown | 有效Effective |
BPDS Technology
极低频电磁探测，输出管道三维坐标
ELF electromagnetic detection with 3D coordinates
