PE non-excavation crossing pipe case
Non-excavation technology can be divided into three categories: laying new pipelines, repairing and replacing old pipelines, and detecting existing pipeline networks.
1. Construction technology for laying new pipelines: shield method, pipe jacking method, guided / directional drilling pipe laying method, pneumatic spear pipe laying method, tamping hammer pipe laying method, and mini-tunnel pipe laying method, among which the pipe jacking method is applied Earliest.
2. Construction technology for repairing old pipelines: in-situ curing method, in-situ pipe replacement method, sliding interpolation method, deformation regeneration method, local repair method, etc.
3. Detecting underground pipeline networks: underground pipeline detectors, water supply pipeline network monitors, telecommunication line fault locators, gas fault detectors, pipeline cameras, ground penetrating radars, sonar series, etc.
