Self-locking polyethylene corrugated solid-wall pipe for top-pull installation
This construction technique, which employs a double-acting jacking and self-locking sealing process, strikes a balance between horizontal directional drilling and slurry-balanced pipe jacking. It constitutes an integrated construction system encompassing "technique + pipe material + working shaft." This method combines the broad geological adaptability and strong obstacle-handling capabilities of directional drilling with the precise elevation control offered by pipe jacking. At the same time, it requires minimal space, provides excellent pipe sealing performance, boasts high rigidity, and ensures overall structural integrity. As such, it can be applied to a wide range of projects characterized by high construction difficulty and restrictive construction conditions—such as areas with quicksand or silty soils, locations where excavation is impossible and conventional pipe pulling is impractical, and sites with limited space or underground water. In all these scenarios, this technique offers significant engineering advantages.
